The present study aimed to screen the in vitro antimicrobial activity of ethyl acetate fraction isolated from the leaves of Heterophragma adenophyllum against Escherichia coli, Salmonella enterica, Staphylococcus aureus, Bacillus anthracis and Klebsiella pneumonia broad spectrum microorganism. The study was carried out by using standard nutrient broth for microbes and streptomycin was taken as a positive control. Ethyl acetate fraction used as a test sample and DMSO as a negative control. From the results of the zone of inhibition it was concluded that the ethyl acetate fraction was pusses in vitro antimicrobial activity while results of minimum inhibitory concentration, it was revealed that all bacterial strains were sensitive towards selected fraction for the study.

Antibiotic Prophylaxis should be appropriate to reduce the risk of postoperative surgical infections. Surgical Site Infections (SSIs) are responsible for Increased Mortality and Morbidity rate during surgical operations which lead to major complications. The inappropriate and overuse of antibiotics effects the cost and efficacy of drugs which leads to the resistant bacteria. To assess the pattern of antibiotic usage in surgical in-patients and for Postoperative wound infections. The present study is a prospective observational study done for a period of six months in Basaweshwara Medical College and Research Centre, Chitradurga in surgical ward. A Total of 162 patients were enrolled into the study. Among them, Surgical Site Infection (SSIs) was found in 37 (22.8%) patients and patients without SSIs are 125 (77.2%). The patients with age group 25-60 years were 104 (64.2%) in which SSIs are more (23).According to the study male patients underwent more surgeries (107 (66%)) in which 21 (56.8%) are with SSIs. Infection rate were more in males when compare to females in the study. A total of 265 antibiotics were used among 162 patients in which third generation cephalosporins are more preferred. The study concludes that there is a proper need to control the use of antibiotics appropriately. The inappropriate use leads to economic burden and resistance. SSIs may decrease the quality of life of the patients. Hence minimization of SSI is also very important in the developing countries by maintaining infection control plans by suitable organizations which makes an impact on the infections

To evaluate the effect of methanolic extract of leaves of Ocimum gratissimum linn. on neutrophil phagocytic function. Were we used different concentrations (50,100,200μg/ml) of methanolic extract of Ocimum gratissimum was subjected to study its effect on different in-vitro methods of phagocytosis. such as neutrophil locomotion, chemotaxis, immunostimulant activity of phagocytosis of killed Candida albicans and qualitative Nitro Blue Tetrazolium test using human neutrophils. This preliminary study revealed that Ocimum gratissimum extract has stimulated chemotactic, phagocytic and intracellular killing potency of human neutrophils at the different concentration. From the results obtained it can be observed that the methanolic extract of Ocimum gratissimum leaves stimulates cell-mediated immune system by increasing neutrophil function phagocytic activity.

A simple, economic and precise RP-HPLC method has been developed and validated for simultaneous estimation of thiocolchicoside (THC) and diclofenac (DCF) both in bulk drug and in capsule formulation. Reversed-phase chromatography was performed on a C18 Phenomenex-Gemini column with mobile phase acetonitrile: water (70:30 % v/v, adjusted at pH 3.0) at a flow rate of 1.0 ml/min. Detection was performed at 258 nm and sharp peaks were obtained for THC and DCF at a retention time of 1.537 min and 4.010 min respectively. The method was validated for accuracy, precision, detection and quantification limits, and system suitability in accordance with ICH guidelines. Linear regression analysis data for the calibration plot showed there was a linear relationship between response and concentration for THC in the range 4 - 24 μg/ml with the correlation coefficient 0.9998 and the linear regression equation y = 20.64x + 26.08. Linearity was observed in the range of 25 - 150 μg/ml with the correlation coefficient 0.9998 and the linear regression equation y = 11.13x + 65.27 for DCF. The detection (LOD) and quantification (LOQ) limits for THC were found to be 1.052 and 3.187 μg/ml and for DCF it was found to be 1.475 and 4.470 μg/ml. Statistical analysis proved that the method was precise, reproducible and accurate for simultaneous estimation of THC and DCF. The wide linearity range, sensitivity, accuracy, short retention time, and simple mobile phase imply that the method is suitable for routine quantification of THC and DCF with high precision and accuracy.

  Natural remedies from medicinal plants are considered to be effective and safe alternative treatment for liver toxicity. Our aim was to demonstrate the hepatoprotective effect of petroleum ether, methanol and aqueous extracts of Cassia tora seed with a view to explore its use for the treatment of hepatotoxicity in human. These extracts were used to study the hepatoprotective effect in paracetamol induced hepatotoxic model. In aqueous and methanol extracts treated groups there was statistical significant decrease in the levels of serum bilirubin, serum glutamate oxaloacetate transminase (SGOT), serum glutamate pyruvate transminase (SGPT) and serum alkaline phosphatase (SALP) as compared to the hepatotoxic group. In the histopathological study the hepatotoxic group showed hepatocytic necrosis and inflammation in the centrilobular region with portal triaditis. Aqueous and methanol extracts treated groups showed minimal inflammation with moderate portal triaditis and their lobular architecture was normal. It can be concluded that the aqueous and methanolic extracts of Cassia tora seed were not able to revert completely hepatic injury induced by paracetamol, but it could limit the effect of these drug in liver. The effects of extracts were comparable with standard drug silymarin. Keywords: Hepatoprotective, cassia tora seed, paracetamol.

Schiff Base derivatives are important class of compounds. They possess different types of Biological activities like antibacterial, antiviral, anti HIV, antifungal etc. Schiff base derivatives are prepared by the condensation of aldehyde and amine and these compounds are characterized by chemical and instrumental methods. Their important biological properties have been investigated. Key words: Schiff Base derivatives, Biological study, pyrimidine derivatives, Hydrazone derivatives
