Comparative Review of two Anti-Diabetic Herbal Drugs - GymnemaSylvestreand CostusIgneus

Nisarg Bhatt, Mitali Shrimanker

Diabetes mellitus is one of the common endocrine disorders characterized by deranged secretion of insulin and/or glucagon with extensive disturbance of carbohydrate, protein and lipid metabolism. GymnemaSylvestre is a woody, climbing plant of tropical forests of central and southern India and in parts of Africa. Gymnema has played an important role in Ayurvedic medicine for centuries. Its use has been confined primarily to the management of diabetes mellitus and similar hypo/hyperglycemic conditions. The first scientific confirmation of G. sylvestre use in human diabetics came almost a century back when it was demonstrated that the leaves of G. sylvestre reduce urine glucose in diabetics. Costusigneus Nak commonly known as fiery costus, Step ladder or Spiral flag or Insulin plant, is native to South and Central America. This is a recent introduction to India from America as an herbal cure for diabetes and hence commonly called as 'insulin plant.

Microneedle based drug delivery system and advantages in ocular drug delivery

GuravAtul S, DaptardarTanvi A, KhakalNilima N, GavhaneYogesh N, SayyadFahim J

The stratum corneum of the skin or the sclera/cornea of the eye, the outermost layer of the skin and others has the principal barrier to topically-applied medications. Thus, many therapeutic agents are limited by their inability to reach the systemic circulation. Transdermal delivery of hydrophilic drugs and macromolecular agents of interest is problematic. Therefore, facilitation of drug penetration through this barrier may involve by-pass or reversible disruption of molecular architecture. Microneedles, when used to puncture skin, will by-pass the barrier and create transient aqueous transport pathways of micron dimensions and enhance the transdermal permeability. These micropores are orders of magnitude larger than molecular dimensions, and, therefore, should readily permit the transport of hydrophilic macromolecules. This microneedle based drug delivery system will useful for the eye treatments by avoiding drawbacks of topical administration of drug, multiple drug treatment and other dosage form intended in the eye. This review gives the details of history, various types of microneedles, drug delivery, fabrication methods, manufacturing, evaluation and, importantly, investigations of clinical safety of microneedles.

Mouth Dissolving Tablets -An Overview

Dipali Malhotra, Manish Sinha

Mouth dissolving tablets (MDT) have received ever increasing demand during last decade and It is a rapidly a growing area in the pharmaceutical industry. After introduction into the mouth these tablets dissolve or disintegrate in the mouth and leaving an easy to swallow residue. Novel MDTs address the patient and pharmaceutical needs of convenient dosing particularly for busy or traveling patient, pediatric, geriatric and psychiatric patients who have difficulty in swallowing (dysphagia) conventional tablets and capsules. These tablets also have faster onset of action due to buccal absorption of the drug. The popularity and usefulness of the formulation resulted in development of several MDT Technologies. It is expected that this delivery system will get more importance in future as that of conventional delivery systems.

An Overview on Solid Dispersion Techniques Implemented For Dissolution Enhancement of Glimepiride

Saroj Bala, Mahesh Kumar Kataria, Ajay Bilandi

Drugs belonging to BCS class II, low solubility and high permeability; undergo dissolution-rate limited gastrointestinal absorption. Glimepiride is one of the famous drugs belonging to BCS class II. Its poor aqueous solubility usually causes poor dissolution and unpredicted bioavailability. Hence, formulation techniques that accelerate drug dissolution can guarantee a parallel improvement in bioavailability. Now a days different techniques are available to enhance the solubility of drug like co-solvent, solid dispersion, chemical modification of drug, liquisolid technique etc. One of the favorable strategy to improve the solubility and hence bioavailability of poorly water soluble drugs is theformulation of solid dispersion. The solid dispersion may be prepared by solvent evaporation method, melting method, melt solvent method, kneading method, co-grinding method, co-precipitation method, modified solvent evaporation method, spray drying, gel entrapment techniqueand co-precipitation with supercritical fluid. This review article comprises of the research materialized in the field of solubility and dissolution enhancement of glimepiride.

Co-Crystallization of Glipizide & Rosuvastatin Calcium and it’s Characterization

Ashwini Deshpande, Tanvee Patole

Co-crystals consists of API and a stoichiometric amount of a pharmaceutically acceptable co-crystal former. Pharmaceutical Co-crystals are nonionic supramolecular complexes and can be used to address physical property issues such as solubility, stability and bioavailability in pharmaceutical development without changing the chemical composition of the API. Maximum of the drugs belong to BCS class II, means these are drugs which have low solubility and high permeability. There are various methods of solubility enhancement such as salt formation, solvates, polymorphs, complexation, co-crystallization, etc. Co-crystallization mainly consists of two components the API and the coformer. Thse coformer is the one which acts as a main component for solubility enhancement. In case of ionization or salt formation there is a drawback as compared to co-crystallization. In case, of salt formation or ionization presence of an ionic center is required. This is not a requirement in case of co-crystallization.FDA has approved such combination called Juvisync1 (Sitagliptin and Simvastatin) in 2011.Glipizide belongs to the anti-diabetic class of drug and Rosuvastatin calcium is a cholesterol reducing agent. As both these drugs are class II drug, solubility issues has to be solved. As Glipizide was available not in its salt form, its co-crystallization was decided to do. Hence, co-crystallization method was selected as the method to enhance the solubility. The co-crystals were characterized and showed the conformance of the presence of both the APIs.

To evaluate the preliminary phytochemical, antioxidant and anti-inflammatory activity of77 Anaphyllum wightii Schott. Bovine Serum Albumin denaturation inhibition assay was used for the evaluation of in-vitro anti-inflammatory activity and DPPH. Free radical scavenging and super oxide scavenging assays were used to assess the antioxidant activity of chloroform and aqueous extracts of the tubers of Anaphyllum wightii Schott. In anti-denaturation study, it was observed that chloroform extract showed greater percentage of inhibition of bovine serum albumin denaturation ie 49.2% whereas aqueous extract showed 38.4% at the 400µg/ml concentration respectively. In case of antioxidant screening also, chloroform extract showed better antioxidant power compared to aqueous extract dose dependently. Among the two extracts evaluated for anti-inflammatory and antioxidant activities chloroform extract of Anaphyllum wightii was found to possess significantly good anti-inflammatory and antioxidant activities and this can be attributed to the presence of alkaloids, saponins, flavonoids and phenolic compounds.

Studies on the Control of Mosquito, Aedes Aegypti using the Ethanol Seed Extract of Annona Reticulata As A Biocide

Murukoli Muhammed, Hima Ramachandran Chennate, Muthusamy Manimegalai

In the present study the seeds of Annona reticulata was extracted with ethanol, and evaluated for mosquitocidal effect against the dengue vector Aedes aegypti. The preliminary phytochemical analysis showed the presence of alkaloids, flavanoids, glycosides, steroids and phenols in the ethanol seed extract of Annona reticulata. The percentage of egg hatchability in ethanol seed extract was 73% in 0.1%, 59% in 0.2% 42% in 0.3%, and 25% in 0.4%, 11% in 0.5% respectively and 100% hatchability was seen in control. The level of the toxicity of Annona reticulata was expressed in terms of LC50/24 hour value. The LC50 values of ethanol seed extract for I, III & IV instar larvae  and pupae of Aedes aegypti were 0.717 %, 1.263 %, 1.369 %, 1.425 % respectively. The morphogenetic abnormalities are commonly caused by botanical extracts and the disturbance from the growth regulating hormones. It is therefore suggested that Annona reticulata derivatives are considered for vector control operations besides their use in other fields after exploring field trails.

Kiran B. Aher, Girija B. Bhavar, Hemant P Joshi, Sanjay R. Chaudhari

The objective of present study was to prepare and evaluate Zaltoprofen (ZLT) enteric coated oral mucoadhesive sustained release (SR) tablet in order to improve its GI residence time and improve its bioavailability by using natural biopolymers like xanthan gum and semisynthetic polymer HPMC for its safe use in rheumatoid arthritis, osteoarthritis, ankylosing spondylitis condition. The sustained release polymers, hydroxypropyl methylcellulose (HPMC) of different viscosities and xanthan gum evaluated in different proportions as a major matrix material. Drug-polymer compatibility studies by FTIR and DSC gave confirmation about their purity and showed no interaction physically between drug and selected polymers. ZLT matrix tablets were prepared by wet granulation.  The effect of polymer concentration on the drug release profile and in-vitro bioadhesion of the matrix tablets was studied. A 32 full factorial design was utilized in the optimizing the levels of HPMC and Xanthan gum. Concentration of HPMC K4M and the concentration of xanthan gum per tablet were used as the independent variables.  The dependent variables were the bioadhesive strength, percent drug dissolved at 2, 6 and 10 hours. The data obtained were fit to a model and polynomial equations were generated. Response surface graph was generated based on these equations. Formulation composition with desired release characteristics and bioadhesive strength were found to be predictive using this model. The optimized factorial batch was further given the coating of Opadry® enteric (94 series) polymer in order to avoid GI disturbances. The Z-22 tablets were kept for stability study at 40°C ±2°C and 75% ± 5% RH for a period of 6 months according to ICH guidelines. The formulation was found to be stable after 6 months of study. The pharmacokinetic parameters Cmax, Tmax, Mean Residence Time (MRT) and Area under Curve (AUC) of developed SR tablet were found to be improved with significant difference (p

Chitta Venkateswararao, K. Venkataramana, V.V. Rajesham

Kidneys are complex organs, which perform several important functions. Though the formation of urine is their most obvious role, but they also perform the vital co-ordination of water and salt metabolism, acid-base balance and secretion of hormones. The effects of occupational or therapeutically exposure to toxic metals on kidney have been known for many years. A large number of chemicals in common usage are potential nephrotoxic viz. Glycols (plastics solvents), paints, lacquers, cosmetics and flavouring extracts. The nephropreotective activity of the poly herbal formulation (composed of the extracts from Terminalia chebula, tinospora cordifolia, Phyllanthus emblica, Portulaca oleracea) was evaluated in Gentamicin induced nephrotoxicity in rats, Gentamicin like other aminoglycoside antibiotics causes nephrotoxicity by inhibiting protein synthesis in renal cells. The serum creatinine and blood urea nitrogen (BUN) were found to be significantly increased in rats treated with only gentamicin, whereas treatment with PHME the effect of gentamicin indicating nephroprotective activity. Among various doses, 200mg/kg, 400mg/kg has shown good nephroprotective activity.

Application of Factorial Design for Optimization of Spectrophotometric Determination of Cefdinir Using MBTH

Noura Hemdan Abou-Taleb, Dalia Rashad El-Wasseef, Dina Tawfik El-Sherbiny, Saadia Mohamed El-Ashry

The target of the present study is to use experimental design in screening and optimizing experimental variables to develop a spectrophotometric method for determination of Cefdinir (CFN) antibiotic. The proposed method is based on the oxidative coupling reaction of CFN with 3-methylbenzothiazolinone-2- hydrazone (MBTH) in presence of FeCl3 in acidic medium forming a green colored chromogen measured at λ max of 660 nm. A 25-2 fractional factorial design was utilized to screen the effect of FeCl3, HCl and MBTH concentrations, in addition to reaction time and nature of diluting solvent on the absorbance of the formed chromogen. One way ANOVA and Pareto ranking analyses have shown that all variables were statistically significant. Full factorial design was then utilized to evaluate the effects of the variables on the selected response. With the help of a response surface and contour plots the optimum value of each variable was determined and used for further experiments. These optimum values were 5mg/mL FeCl3, 0.06% HCl, 4mg/mL MBTH, reaction time of 10 min and methanol as diluting solvent. Beer’s law is obeyed in the range of 0.5-6.0 μg/mL. The proposed method was successfully applied for the determination of CFN in bulk powder and commercial dosage forms without interference from the commonly encountered excipients and additives. The mean recoveries of the analyte in pharmaceutical preparations were in agreement with those obtained from a comparison method, as revealed by statistical analysis of the obtained results using the Student's t-test and the variance ratio F-test.

Amitha Shetty, Shruti Prabhu, Sarvesh Parsekar, Mohd Azharuddin, A R Shabaraya

Colon targeted drug delivery system is capable of protecting the drug in route to the colon i.e. drug gets released and absorbed once it reaches the colon. A multiparticulate system combining pH sensitive property and biodegradability has been investigated to prepare and evaluate Eudragit S-100 coated Sodium alginate microspheres for colon targeting of Tramadol Hydrochloride. Uncoated Tramadol Hydrochloride microspheres were prepared by ionotropic gelation technique using different ratios of Tramadol Hydrochloride and Sodium alginate. Coated Tramadol Hydrochloride microspheres were prepared by coacervation phase separation technique using different ratios of uncoated Tramadol Hydrochloride and Eudragit S-100/ Eudragit L-100. Uncoated and coated Tramadol Hydrochloride microspheres were evaluated for percentage yield, particle size, surface morphology, flow properties, drug content and entrapment efficiency and were found to be within the acceptable range. The uncoated microspheres sustained the release upto 8 hrs whereas coated microspheres sustained the release upto 12 hrs in a pH progression medium mimicking the condition of GIT. The drug release from MC4 formulation coated with Eudragit S-100 (1:4) showed desired rate as there was no drug release observed upto 4-5 hrs, while in colonic fluid controlled drug release was observed releasing about 69.66 % after 12 hrs. The release kinetics followed Peppas showing Super Case II transport. Stability studies suggested formulations were stable. It is concluded from the present investigation that Eudragit S-100 coated Sodium alginate microspheres are promising controlled release carriers for colon targeted delivery of Tramadol Hydrochloride.

A Liquid Chromatography Tandem Mass Spectrometry Method for the Quantification of Tamsulosin: Application to a Pharmacokinetic Study in Healthy Human Subjects

Kuldeep K Namdev, Shireen Rao, Manoj K Singh, Swapnil Sharma, Jaya Dwivedi

A simple, rapid and sensitive high throughput liquid chromatographic method coupled with tandem mass spectrometry (LC–MS/MS) has been developed and validated to quantify tamsulosin in human plasma using tamsulosin D4 as internal standard (I.S). The analyte and internal standard were extracted from 300 μL plasma via solid phase extraction and were separated on a Kromasil C18 column (100 × 4.6 mm, 5 µ) with isocratic elution using acetonitrile: 5 mM ammonium formate (70: 30, v/v) containing 0.05 % formic acid as mobile phase. Tamsulosin was quantified using a triple quadruple mass spectrometer operated in multiple-reaction-monitoring (MRM) mode using positive electrospray ionization. The mass transitions m/z 409.2→228.0 and m/z 413.2→228.0 were used to measure tamsulosin and tamsulosin D4 respectively. The calibration curves were linear (r2 >0.99) over the concentration of 0.1-89.4 ng/mL, where the regression model (1/x2) was best fitted. The intra- and inter-day batches precision (%CV) and accuracy values were found to be within the assay variability limit as per the FDA guidelines. The validated method was successfully applied to a pharmacokinetic bioequivalence study in human volunteers and found selective, sensitive and robust in quantitative measurement of tamsulosin in plasma samples.

Akshaya Alva, Roopa P Nayak, RashmiR. Rao, Mohandas Rai

Tuberculosis is a major infective disease affecting Indian population with high socio-economic impact. For eradication of tuberculosis and successful implementation of Revised National Tuberculosis Control Program – Directly Observed Treatment Short Course RNTCP- DOTS program regular assessment of the condition is imperative.The aim was to determine  the sputum carried out in District Tubercular Centre (DTC), Mangalore. The data of all patients registered from January 2011 to December 2011 were examined.The study was conducted on sample population of 297 patients. Of these, 183 (61.6%) patients were NSP cases and 114 (38.4%) patients were retreatment cases. The mean age of patients in category 1 and category 2 was 40.86± 18.20 and 42.49 ± 13.32 respectively. Males constituted 71.2 % and females were 28.8% of population. No significant difference in distribution with respect to gender (x2 = 1.327, p = 0.249) and residential area (x2 = 1.290, p = 0.256) in each categories. There is significant difference in distribution in category 1 and category 2 with mean age in years in different age category(x2 = 21.521, p = 0.001). Of 183 patients in NSP, 137 patients converted to negative at the end of the 2 month intensive phase with conversion rate of 86.33% and 21 patients converted to negative at the end of extended intensive phase with conversion rate of 67.54 %.The sputum conversion rate was comparable to other study but was less than national average. Conversion rate is less in category 2 compared to category 1 showing the importance of treatment completion in patients with TB. Majority of patients belong to a productive age group between 21-60 years indicating the impact of the disease on socio-economy of patient as well as on the country.

Formulation and Evaluation of Oro Dispersible Tablet of Desloratadine

Shikha Sharma, A. Geetha Lakshmi, Parul Grover

Desloratadine is an antagonist at histamine H1 receptors, and an antagonist at all subtypes of the muscarinic acetylcholine receptor. It has a long-lasting effect and in moderate and low doses, does not cause drowsiness because it does not readily enter the central nervous system. The present study is an attempt to formulate and evaluate the fast dissolving tablets of  Desloratadine. Fast dissolving tablets were prepared by direct compression after masking the bitter taste of drug by solid dispersion method with the aid of superdisintegrants. Seven formulations were developed using two different superdisintegrants in varying concentrations in such a way that total weight of the tablet remains the same. The drug-polymer incompatibility was ruled out by FTIR studies. All the formulated tablets were subjected for pre and post-compression evaluation parameters. A comparison of in vitro drug release of best formulation along with F1 formulation having no superdisintegrants is carried out. All the formulated tablets were shown satisfactory results which complies with official limits. Among the seven formulations, F7 was selected as the best formulation as its wetting time was 33 seconds, disintegration time was 29 seconds and %CDR after 8 minutes was 100.1%. F7 was found to be stable at 25°C ± 2 °C,  60°C ± 5°C and 40 °C ± 2 °C and 75 ± 5 % RH . Formulated tablets containing high concentration of croscarmellose sodium are better and effective than conventional tablets to meet patient compliance, give fast relief from allergy and cost effective.

Rheological Characterization of Bioadhesive Nasal Gels

Grace Rathnam, Narayanan N, Ilavarasan R

Bioadhesive gels improve both effectiveness and efficiency of the product due to intimate contact between a delivery device and the absorbing cell layer.  The interaction at the functional group level often results in the formation of mixtures capable of exhibiting rheological synergy.  Rheological synergy is the demonstration of greatly excess of viscosity and gel like properties when mixed with mucin than if the mucin and gels were examined separately.  This rheological synergism between gels and mucin could be used as an in vitro parameter to determine the mucoadhesive properties. In this study a simple rheological method is used to quantitatively determine various parameters like viscosity enhancement (ηenhance), relative viscosity enhancement of the combination system (ηrel), force of mucoadhesion (F) and viscosity component of bioadhesion (ηb). This is used to quantitatively compare different bioadhesive nasal gels prepared using carbopol which contain cyclodextrin as absorption enhancer. Composition of a gel can strongly influence its rheological properties and even one different constituent can lead to significantly different rheological behavior. The influence of the presence of cyclodextrin and different methods of addition of cyclodextrin was studied. The pattern noticed in this study was that the gels without the cyclodextrin showed the highest force of bioadhesion which was followed by the gels with cyclodextrin as inclusion complex and then by the gels with cyclodextrin as a physical mixture.  These gels were also subjected to Texture Profile Analysis.

Karisetty Basappa, Mangala Lahkar, Anjana Devee

An organism is called “susceptible” to a drug when the infection caused by it is likely to act in response to treatment with this drug, at the suggested dosage. There are many bacterial species, including E.coli are showing an increasing resistance to antibiotics and E.coli is an important pathogen of urinary tract. The growing Prevelance of antimicrobial resistance is a most important health problem and is linked with high morbidity and mortality. Antimicrobial susceptibility pattern of gram negative was observed towards Nitrofurantoin (55.38%) followed by Cotrimaxazole (22.96%), amikacin (25.93) and Ceftriaxone (12.85%) in case of E.coli and Klebsiella. Enterococcus shown maximum sensitivity to linezolid (89.11%) followed by Nitrofurantoin (51.69%), but ofloxicin (9.7%), Imipenem (9.41%) and Amikacin shown very low sensivity. So, the decision on selection of antibiotic therapy should be made in discussion with microbiologist and pharmacist.

Study of Nitrofurantoin Susceptibility in Urinary Isolates of E.coli – A Need to Revert Back to Older Drugs

Raminder Sandhu, Kanwardeep Singh, Gaurav Sharma

Urinary tract infections have a high incidence in general population, with potential complications and constantly shifting trends in drug resistance that emphasizes the importance of selecting appropriate antimicrobial therapy. The present study shall focus on nitrofurantoin susceptibility in urinary E.coli isolates which heralds shifting trends in drug resistance among uropathogens and emphasizes on the need to revert back to older urinary antimicrobial agents. The study shall serve as an update on the susceptibility of E.coli to various commonly used antibiotics. A retrospective study was conducted by analyzing culture results and antimicrobial susceptibility pattern of E.coli isolated from 4533 urine samples collected from both inpatients and outpatients in Microbiology Department of tertiary care institute from January 2013 to December 2013. E.coli isolates depicted maximum sensitivity to Nitrofurantoin (87.12%) followed by Amikacin (86.53%) and Gentamicin (68.19%) whereas resistance remained high to Cefazolin (86.82%), Norfloxacin (84.53%), Cotrimoxazole (82.23%), Amoxyclav (82.23%) and Ciprofloxacin (76.22%). Nitrofurantoin susceptibility of E.coli isolates remained high in females (90.61%) as compared to males (83.09%). Among inpatients maximum sensitivity to nitrofurantoin was exhibited by isolates recovered from Gynae/obstetrics ward (94.59%) followed by pediatrics ward (82.35%). The study depicts promising use of Nitrofurantoin as narrow spectrum antibiotic to de-escalate the selection pressure and as fluoroquinolones sparing drug in areas where Cotrimoxazole resistance remains high in the uncomplicated cystitis. Clinicians should use local surveillance data to formulate empiric selection of antibiotic therapy in urinary tract infections.

Wound Healing Activity of Butea Monosperma in Wistar Rats

Malpani M. O, Rajput P. R

Wound is a physical injury that causes breakdown in the protective function of the skin and the loss of continuity of epithelium with or without loss of underlying connective tissues. Proper healing of wound is essential for the restoration of normalcy in disrupted anatomical continuity and altered functional status of the skin. Wound healing is a complex and dynamic process of restoring cellular structures and tissue layers. It can be divided into 3 distinct phases: an immediate haemostatic phase, an early phase of re-epithelialization, a later phase of dermal repair and remodelling. The present investigation was undertaken to determine the efficacy of Butea monosperma leaves aqueous extract, isolated acidic ingredient and its newly synthesized amide analogue along with silver sulphadiazine as control on burn wound in Wistar albino rats. The histopathological examinations confirmed that the treated animals showed improved rate of epithelialization and wound contraction. On comparison among the impact of test compounds; it was further revealed that, the Butea monosperma leaves aqueous extract and synthesized amide analogue showed significant wound healing activity than isolated acidic ingredient.

Isolation, Biochemical Characterization, Antibiotics Susceptibility of Enterobacteriaceae in Potable Water Sample and Primer Designing for their Rapid Detection

Juhi Saxena, Sonia Siwal, Mratunjay Pathak, Saksham Gupta, Aparna Datta

The contamination of processed or unprocessed drinking water by pathogenic bacteria has been reported worldwide. Even though a high incidence of waterborne diseases have been well documented, enterobacteriaceae is an under acknowledged pathogen of concern to public health in India. The study was aimed to isolate and biochemically characterize Enterobacteriaceae as well as to determine  antibiotic sensitivity pattern and primer designing specific to their signature gene sequences for rapid detection by PCR methods. Total plate count was determined in potable water sample collected from three different sites of Jaipur city and was found to be nearly equal or more than 105 cfu/ ml. Enterobacteriaceae were enumerated using the most probable number method (MPN index). Enterobacteriaceae (n = 36), randomly isolated from three sites, were identified, biochemically characterized and were screened for sensitivity to 9 antimicrobials by the disk diffusion method. The isolated bacteria had shown variable susceptibility and resistance patterns in response to different antibiotics used in the study. Polymerase chain reaction based methods can be a powerful molecular technique for rapid, sensitive and specific detection. Hence, in the present study primers were also designed specific to virulence signature sequences and their specificity was assessed by BLAST.

Adriana GeorgievaBakalova, RossenTodorov Buyukliev, AntoninaTzekova Nikolova, GeorgiTzvetanov Momekov

Four Pd(II) and Pd(IV) complexes with 3-thiolanespiro-5’-hydantoin and 4-thio-1H-tetrahydropyranespiro-5’-hydantoin were synthesized. Thechemical structures of newcomplexes were studied by elemental analysis, IR, 1H, 13C NMR spectra. The spectroscopic investigation of new palladium complexes in comparison with the metal free ligands show that the bonding of the ligands with metal ions is realized through the sulfur atom from the S-containing saturated rings. This coordination mode is in accordance with the data obtained for the platinum complexes with the same ligands. The new complexes were investigated for cytotoxicity on panel of human tumor cell lines. The tested compounds exerted concentration-dependent cytotoxic effects against some of the tumor cell lines.

Effect of drought stress on chlorophyll content, protein and total free amino acid in [Cajanuscajan(L.)Millspaugh]

S.Punyasheeladevi¹, B.Sujatha²

Physiological and biochemical analysis responses of 6-day-old seedlings of two pigeon pea (Cajanuscajan(L.) millspaugh) cultivars namely ICPL-85063 (short duration, lakshmi) and ICPL -87119 (medium duration, Asha) were studied. Stress was applied with polyethylene glycol (PEG-6000) and water potentials were: zero (control), -0.3Mpa (50mM),-1.1Mpa (100mM) and -2.3Mpa (150mM). In this study, the water stress effects on different parameters like chlorophyll content, protein and total amino acid content was measured following the standard methods. Total free amino acid content registered higher values in ICPL-85063. The protein and total chlorophyll content was observed as lower values when compared to their controls in lakshmi cultivar. It was observed that amino acid content was highest in stress level was -2.3Mpa and the least exist in blank. The results of chlorophyll content demonstrate a concentration dependant decline with increasing concentration of polyethylene glycol (PEG-6000). ICPL-85063 cultivar showed better performance in total amino acid content than Asha cultivar. It was established that the applied doses of PEG-6000 caused stress on young pigeon pea plants, which found suppression of photosynthesis.

Husnul Maab, Sattar Bukhsh Awan, Usman Zafar Paracha

Meloxicam has been analyzed in a number of ways but the methods proved to be slow and tedious due to the involvement of buffers, maintaining of pH and lengthy process of HPLC or potentiometric titration. Our aim was development and validation of a new, fast, simple and inexpensive method for the analysis of Meloxicam by UV visible spectrophotometry. A new solvent system consisting of Acetonitrile and Methanol (70:30) was formulated by trial and error method. Different concentrations of meloxicam were made in this solvent system and were analyzed by UV visible spectroscopy. The absorbance was studied over the range of 240 to 400nm. The obtained results were used to study and calculate various validation parameters of this technique.  The calibration curve was found to be linear over the range of 0.1 to 0.6ug/ml with linear coefficient of 0.999. The precision was calculated to be equivalent to 0.251%. The LOD and LOQ of this method were found to be around 0.006ug/ml and 0.02ug/ml respectively. The system showed accuracy over the range of 90-100%. This method proved to be a good alternative to existing reported methods as it showed sensitivity, accuracy as well as reproducibility with low cost and time.

A Study on Contamination of Water by Salmonella in and Around Coastal Regions of Trivandrum District, Kerala State, India

I .S. Aruni, P. Prbakaran

During June 2013 to October 2013, a total of 100 water samples were collected from various coastal regions of Trivandrum district, Kerala state, India. These samples were examined for the presence of pathogenic bacteria especially the pathogenic salmonella species. Water samples were collected in sterilized screw caped glass bottles, transported to the microbiology laboratory of Noorul Islam Institute of Medical Sciences, Neyyattinkara, Trivandrum, Kerala and processed according to the standard protocols for the identification of pathogenic Salmonella species, within 6 hours. The type of water included in the present study were pond water, river water, household water, well water, municipality supplied tap water and packaged bottled water. The present study revealed that the pond water, river water and household water were contaminated with pathogenic Salmonella species. The packaged bottled water and municipality supplied tap water devoid of Salmonella contamination. So based on the present study it is strongly suggested that water should be boiled before use or use packaged bottled water of good quality for drinking purposes.

Detection of oncoproteins in the Acute Promyelocytic Leukemia (APL) subtypes

Mohsen Hmidpour, Baharak Jalali1 Mostafa Rezaie Tavirani, Abbas Hajfatali3 Kamran AliMoghadam, Rafie Hamidpour

Acute promyelocytic leukemia is classified with a classic translocation  t(15;17) (q22;q12), and the other subtypes such as: t(11;17 ( (q23;q21) , t(11;17)) q13;q21)  t(5;17) (q35;q21).   Unfortunately, about 5% of APL subtypes, do not have a good prognosis due to resistance to ATRA.   Therefore, there is a major concern for hematologists and oncologists to diagnosis subtype of APL and start the treatments as soon as possible. 28 patients with suspected acute promyelocytic leukemia who hospitalized in two Iranian general hospitals were under study . In this study, we applied molecular and western blotting methods to detect major oncoproteins in APL subtypes. Cytogenetic results have been shown that the PML / RARa oncogene is positive in 26 of patients, and two of them did not have appreciated result. The results of western blotting showed that in 26 patients, the proteins with molecular weights 115 and 85 KD was detected by specific anti-RARa antibodies. The western blotting assay for one patient showed the protein with molecular weight of 85 KD was detected by specific anti- PLZF antibodies. The results indicate that the molecular and western blotting techniques were able to differentiate the APL with t (15; 17) from the other subtypes, like t (11; 17). We indicated by western blotting, two oncoproteins:  PML / RARa and PLZF / RARa, respectively to the relative two translocation t (15; 17) and t (11; 17). Western blotting techniques can be a substantial contribution of to the final diagnosis of leukemia.

3-(2-bromacetyl) phenyl benzoate is key starting material used in synthesis of phenylephrine, (R)-3-[-1-hydroxy-2-(methylamino)ethyl]phenol which is selective α1-adrenergic receptor agonist used primarily as decongestant, as an agent to dilate the pupil, and to increase blood pressure. Hence the current research work was aim to synthesize a series of 3-(2-bromacetyl) phenyl benzoate  derivatives by treatment of secondary amines with carbon disulphide and 3-(2-bromacetyl) phenyl benzoate  in presence of strong base in ethanol afforded the corresponding Dithiocarbamates. Their chemical structures are characterized by 1H &13C NMR, MS, Elemental analysis, and chromatography methods (TLC). The antimicrobial activity was evaluated by their MIC and zone of inhibition by taking Penicillin, Streptomycin and Amphotericin as standard reference drugs. The microbial assay revealed that compounds D4 and D5 showed the most potent antimicrobial activity against variety of bacteria as well as fungal isolates, which may be a promising antimicrobial leading compound for the further research.
