The present study investigates neuroprotective effect of hydroxy citric acid (50%) on phenytoin induced cognitive impairment and oxidative stress in rats.Male Wistar rats were divided into 6 groups and each group received vehicle, phenytoin (25mg/kg, i.p) and hydroxy citric acid (400 and 800mg/kg, orally) for 14 days respectively. Memory and learning was evaluated by using the Rectangular maze, Mo...
Strychnos potatorum Linn. is a medium sized deciduous tree belonging to the family Loganiaceae. The collected seeds of Strychnos potatorum were dried and powdered. Methanolic extract of these seeds was prepared by cold maceration. The preliminary phytochemical screening of the crude extract revealed the presence of flavonoids and phenolic compounds. The crude extract was partitioned (gradient) wit...
The application of nanobiotechnology is an emerging area of nanoscience and nanotechnology. In the present studies, tungsten nanoparticles were synthesized and reduced chemically, and character-rization was done by UV, SEM, TEM, FT-IR, and XRD. The size of nanoparticles was found to be 20 nm. Further, these nanoparticles were teste for various biological applications. In antimicrobial activity, it...
PHARMACOGNOSTICAL EVALUATION AND PRELIMINARY PHYTOCHEMICAL ANALYSIS OF DIFFERENT PARTS OF LAGERSTROEMIA SPECIOSA
The present study aimed to determine the pharmacognostical evaluation and phytochemical analysis of the plant part of Lagersreomia speciosa. In this study, a macroscopical, microscopical evaluation was done. Various quantitative parameters such as total ash, acid insoluble ash, water-soluble ash sulphated ash, extractive value with various solvent were done. In the preliminary phytochemical analys...
The studies on the constituents of aerial parts of Stellaria media Linn. (Caryophyllaceae) have led to the isolation and characterization of three new compounds ─ (1), (2) and (3). Structure elucidation of the new compounds was carried out using 1H NMR, 13C NMR, Mass spectrometry together with other complementary techniques (UV and IR). The major findings of the study include: Compound 1 was sep...
Trandermal drug delivery systems are potential sources of administrating drugs through and have certain advantages as delivering a therapeutically effective amount of drug across a patient's skin. Medicated Tattoos is one of the upcoming approaches in transdermal drug delivery. Researches reveal that humans from the generations have used tattoos for various reasons like symbol of rank, religious/s...
DEVELOPMENT AND EVALUATION OF PEPTIDE LOADED MUCOADHESIVE MICROSPHERES: IN AN EFFORT TO IMPROVE NASAL BIOAVAILABILITY OF PEPTIDE
The nasal drug delivery system has been a promising route for delivery of proteins and peptides as it can avoid degradation in the gastrointestinal tract and metabolism by liver enzymes. However, due to the rapid mucociliary clearance, the bioavailability of proteins and peptides is still low. Hence, mucoadhesive microspheres may prolong the residence time of peptide drugs in nasal cavity and impr...
FORMULATION DEVELOPMENT AND EVALUATION OF FENOFIBRATE AND ROSUVASTATIN IN COMBINATION TABLETS AND RELEASE RATE IMPROVEMENT
The work was aimed to develop an immediate release tablet formulation of Fenofibrate and Rosuvastatin in combination for better treatment as well as management of hypercholesterolemia and prevention of cardiovascular diseases. The target was also set to improve the dissolution profile of poorly soluble Fenofibrate. For manufacturing these immediate release combined formulation tablets, Hot-Melt Te...
The majority of the drugs that are available in the market which are intended for activity in the central nervous system, are not capable of being transported across the Blood-brain barrier. The nasal route of drug administration is one of the most promising routes of drug administration that can permeate the drug through BBB. The permeability of drugs across the BBB is depending on the physicoche...
PRIMARY SCREENING FOR EXTRACELLULAR ENZYME PRODUCTION, POLY-HYDROXYBUTYRATE PRODUCTION AND SALT TOLERANCE BY BACTERIA ISOLATED FROM KUTCH REGION OF GUJARAT
Gujarat has the second largest mangrove ecosystem in India, and mangrove ecosystems are known for their extreme environments and hence extremophiles that can produce novel enzymes can be found in these extreme environments. In this study, ninety-three bacterial isolates were obtained in pure cultures from soil samples collected from Kandla, Mundra and Tuna of the Kutch region of Gujarat in the win...
