The prophylactic efficacy of garlic (Allium sativum Linn.) (Alliaceae) extract was studied on changes in WBC differential count pattern in male albino rats. The rats were divided into four groups A, B, C and D, keeping group A as a healthy control. The garlic extract was tried in three different doses, 1ml, 2ml and 4ml/ kg body weight as low, medium and high dose respectively and given orally for the period of 7, 14, 21 or 28 days daily to the rats of group B, C and D as stated above. The results clearly indicate that a significant increase (P<0.01) in lymphocyte and eosinophil percent and a significant decrease (P<0.01) in neutrophil and monocyte percent at low and medium dose but at higher dose their percentage increases within the normal values. This investigation indicates not only the benefits and drawback of raw garlic but also its uses in regulation of certain parameters for well-being of...

Direct compression is the preferred method for the preparation of tablets. Co-processing is the one of the most widely explored and commercially utilized method for the preparation of directly compressible vehicles. The objective of the present study is to prepare and characterize pregelatinized starch-poly vinyl pyrrolidone (PGS-PVP) co-processed excipient and to evaluate its application as directly compressible vehicle in tablet formulations. PGS-PVP co-processed excipient was prepared by gelatinizing potato starch in the presence of PVP and drying the resulting mass. The co-processed excipient prepared was characterized by determining melting point, solubility, swelling index in water, pH, and micromeritic characters namely particle size, bulk density, tapped density, angle of repose and compressibility index, by FTIR spectra and evaluated for its application in tablet formulations. PGS-PVP co-processed excipient prepared by gelatinizing potato starch (49 parts) in the presence of PVP (1 part) is a crystalline, discrete and free flowing powder. It is insoluble in water and aqueous fluids of pH 1.2, 4.5 and 7.4 and in several organic solvents. It exhibited...

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...
