The ethanolic extract of leaves of Acalypha hispida was evaluated for phytochemical, cytotoxic and antibacterial activities. Phytochemical studies revealed the presence of flavonoids, saponins, glycosides, reducing sugars and steroids. Cytotoxic activity was investigated by brine shrimp (Artemia salina) lethality assay. The extract showed potent cytotoxic effect (LC50 19.95µg/ml) which is comparable to standard cytotoxic drug chloramphenicol (LC50 7µg/ml). Antibacterial activity was tested by disk diffusion method. The extract exhibited significant antibacterial activity against Salmonella typhe and moderate activity against Enterococcus coli, Streptococcus saprophyticus and Streptococcus agalactin whereas Shigella dysentery found resistant at 250µg/disc and...

Bionanotechnology has emerged up as integration between biotechnology and nanotechnology for developing biosynthetic and environmental friendly technology for synthesis of nano materials. Silver has been known to have effective bactericidal properties for centuries. Nowadays, silver based topical dressings have been widely used as a treatment for infection in burns, open wounds, and chronic ulcer. As the pathogenic organisms are getting evolved day by day due to mutation and gaining antibiotic resistance, an important industrial sector of nanosciene deals with the preparation and study of nanoparticles in antibacterial clothings, burn ointments and coating for medical device. The size of nanomaterials is much smaller than that of most biological molecules and structures, therefore nanomaterials can be useful in both in vivo and in vitro biomedical research application. The purpose of the study is to synthesis and characterizes the fungal silver nanoparticles using F.oxysporum. Further investigation of the shape and size of fungal nanoparticle was done by X-ray diffraction and Scanning electron microscopic studies. A silver nanoparticle at different concentration was assessed...

Nalbari district is situated in between 26°N and 27oN latitude and 92oE and 97oE longitude. It lies between Kamrup and Barpeta district of lower Assam. Nalbari has a population of 1138184 (2001 census). An ethnobotanical Survey was conducted in 2010 in selected villages to explore the medicinal plant used by the villagers to cure Diabetes. This villages are inhabited by Boros, Koch, Muslim communities. The indigenous knowledge of local traditional healers and native plants used by the villagers to cure Diabetes were collected using a questionnaire and personal interviews. Total 30 villagers in the age group of 30-68 years were interviewed out of which 3 were local healers. The investigation reveals 35 species of plants belonging to 28 families which are used to cure Diabetes. It is found that the whole plant is used for curing the ailment but mostly fresh juice, powder, fresh leaves, paste or decoction in water remains the most preferred method of preparation. Most plants are very effective remedy when used in a combination or...

Objective: Analysis of prescribing pattern of antihypertensives in patients with hypertension alone and with coexisting diabetes mellitus. Materials and Methods: A cross sectional study was conducted in an outpatient and inpatient department of general medicine at JJM Medical College hospital for a period of 3 months (July 2011 to September 2011). Prescriptions of the patients were collected and relevant data was entered in the preformed proforma and analyzed. Results: A total of 210 prescriptions were analyzed using chi square test. Out of which 126 prescriptions were of patients with hypertension alone which contain calcium channel blockers (30%), beta blockers (26%), angiotensin receptor blockers (15%), angiotensin converting enzyme inhibitors (4%) and fixed dose combinations of angiotensin receptor blockers with hydrochlorothiazide (11%) and combination of amlodipine with hydro-chlorothiazide (2.5%).84 Prescriptions of hypertension with coexisting diabetes mellitus had calcium channel blockers (24%), angiotensin converting enzyme inhibitors (19%), angiotensin receptor blockers (13%), beta blockers (13%), and fixed dose combinations of angiotensin receptor blockers with hydrochlorothiazide (18%) and combination of amlodipine with hydrochlorothiazide (6%).[χ2=17.01,...

Phytochemical screening and antibacterial activity of aqueous and methanolic root extracts of Stachytarpheta indica Vahl. was assessed. Phytochemical analysis revealed the presence of flavonoids, terpenoides, tannins and reducing sugars. The antibacterial properties of both the aqueous and methanolic extracts were studied against clinically important bacteria viz., Escherichia coli, Bacillus cereus, Pseudomonas aeruginosa and Enterobacter aerogens by disc diffusion method. The aqueous extract showed significant activity against all the presently investigated species of bacteria which is comparable with standard antibiotic streptomycin. At the concentrations of 50-100µg /disc, aqueous extract showed significant zone of inhibition against E. coli, (14 mm), B. cereus (13 mm), P. aeruginosa, (17 mm), and E. aerogens (7 mm). Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) have been determined. The MIC values observed was 20, 30, 5 and 25µg/ml (for aqueous extract) and 40, 35, 20 and 30µg/ml (for methanolic extract) against E. coli, B. cereus, P. aeruginosa, and E. aerogens respectively. Further isolation of active compound responsible for the activity could be the potential...
