1 publicationEvaluation of Methanol Extract of Tephrosia Pumila for Anti Ulcer properties.
The objective the present work was to investigate anti ulcer potentials of methanol extract of Tephrosia pumila. The aerial parts of Tephrosia pumila were dried under shade, powdered and deffated with petroleum ether and then marc left over was subjected to methanol extraction using soxhlet apparatus using soxhlet apparatus. Antiulcer activity of methanol extract was determined against stress induced and aspirin induced ulcers in experimental animal models. The total number of ulcers formed, ulcer index, percentage inhibition, ulcerated area, protected area, pH and Total acidity were parameters in the study. In present study, methanol extract of Tephrosia pumila have significantly reduced the total number of ulcers formed, ulcer index, ulcerated area and total acidity in therapeutic groups compare to vehicle control and there by significantly increased percentage inhibition of ulcers and protected area which was evident by significant rise in pH of gastric content. The effect of extracts was dose dependent and results were comparable to that of standard drug omeprazole. The results of the present work suggest that the methanol extract of Tephrosia pumila possess significant anti-ulcer potentials against experimentally induced ulcers in albino rats. Â

1 publicationNanosponges: Revolution in Nanotechnology
Nanosponges are the advancement in nano technology, which are the conspicuous answers for the various formulation challenges like low aqueous solubility, controlled release and targeted release. Nanosponges do not show the bursting release which is the main obstacle in the most of the nano particles formulations. Nanosponges are a novel class of nanoparticles with nanostructured hyper branched polymers and few nanometres wide cavities, in which a large variety of substances can be encapsulated. Nanosponges also have colloidal sizes with a mean diameter of less than 1 μm and narrow size distribution and form opalescent suspensions on dispersion in water. The formulation of nanosponges involves simple chemistry. Nanosponges could be a perfect solution for resolving the scalability issues of various nano approaches in the pharmaceutical industry, paving the way for a nano-revolution.
