In present study antiproliferative activity of Rutin was evaluated on HeLa cell line induced cervical cancer in rats. For this study, 30 rats were divided into 5 groups and each group containing 6 rats each. Group I- normal saline treatment for 45 days, Group II- cancer cells (1×106 cells in 0.1ml/rat), Group III– 5-Fluorouracil (20mg/kg + 1×106 cells in 0.1ml/rat), Group IV- Rutin (50mg/kg + 1×106 cells in 0.1ml/rat), Group V- Rutin (70mg/kg + 1×106 cells in 0.1ml/rat). After 24 h of tumour inoculation intraperitoneally, Rutin was administered daily for 45 days. After administration of last dose followed by 18 hrs fasting, rats were sacrificed for observation of antiproliferative activity. The change in body weight, body circumference of tumour bearing hosts and simultaneous alterations in haematological profile, serum (Triglycerides, Total protein, Total cholesterol, GGT, ALP and glucose) and liver biochemical parameters (lipid peroxidation, GSH and antioxidant enzymes-CAT, GPx) were estimated. The changes in tissue enzymes-Glucose-6 phosphate dehydrogenase, Hexokinase, Succinate dehydrogenase and CytochromeP450 levels were also estimated. Rutin maintained the...

Olmesartan medoxomil, a BCS class II drug, is an angiotensin-II receptor antagonist used for the treatment of hypertension. A liquisolid tablet of Olmesartan medoxomil was developed to improve its dissolution and flow properties. The commonly used carrier Avicel was compared with Neusilin. Because of higher liquid load factor, Neusilin was selected as a carrier for further optimization study using 32 Factorial design. Two independent factors, % drug concentration in a liquid vehicle (X1) and carrier coating ratio (X2) were studied, each with three levels and the systems was assessed for two dependent variables; % drug dissolution and angle of repose. Mathematical equations and response surface plots were used to relate the dependent and independent variables. All prepared liquisolid formulations were characterized for pre-and post- compression parameters. The optimized formulation F7 (15% drug concentration and 30 carrier coating ratio) was tested for X-ray powder diffractometry and FTIR. Results showed that maximum drug dissolution was exhibited by systems with minimum drug concentration in liquid vehicle and optimum carrier to coating ratio....

The present study was initiated to quantify the Isoflavones content that accumulated in soybean transgenics with RnPPARγ gene by using high performance liquid chromatography. The effects of methanolic leaves extract of transformed soybean in 3T3-L1 adipocyte cell line. The RnPPARγ transgenic soybean variety JS335 was developed and transgenics were confirmed by PCR and Southern blot techniques. The quantification of isoflavones compounds by HPLC showed that methanolic leaves extracts of transformed soybean contained Genistein (1.67µg/g extract), Daidzein (2.76µg/g extract), Rutin (32.06µg/g extract) and Quercetin (48.40µg/g extract) and methanolic leaves extracts of non-transformed soybean contained Genistein (1.23µg/g extract), Daidzein (2.33µg/g extract), Rutin (26.16µg/g extract) and Quercetin (43.03µg/g extract) by comparing the chromatogram of the reference standards. In the present study revealed that secondary metabolite content was higher in the transformed plant than non-transformed plants. After treatment of transformed methanolic leaves, extracts on 3T3-L1 mature adipocytes significantly ameliorated lipid droplet accumulation and droplet reduction in adipocytes might be the result of lipid metabolism by...

The aim of the present study was to investigate the potential of a micro-emulgel formulation for topical delivery of Terbinafine. Terbinafine showed highest solubility in propylene glycol among the available oil phase. Tween 80 and polyethylene glycol 400 were used as surfactant and co-surfactant respectively. Using pseudo-ternary phase diagram 1:2 ratio of surfactant: co-surfactant was selected. Using Central Composite Design thirteen formulations with varying ranges of Smix and oil phase were prepared. Final formulation was selected on the basis of transmittance. From optimization plot it was concluded that 27.93% of Smix and 6.51% of oil phase gave maximum transmittance. Then, optimized formulation was used to prepare final microemulgel of terbinafine. Thirteen gel formulation from varying concentration of carbopol 934 and hydroxypropylmethyl cellulose was prepared and evaluated for extrudability, spread ability, drug content, in-vitro drug release, rheological study and in-vitro antifungal activity against Teniapedis. Formulations with suitable consistencies were selected and optimization was done on the basis of drug release and ex-vivo permeation study in goat skin. Formulation with 0.45gm...

Lipid metabolism in animals has recently gained growing interest among researchers. Among organic compounds, it is only protein and nucleic acids that for a long time have remained in primary focus of research, though lipids are now known to be essential for the origin of life and development of organic forms. Metabolic processes are very active in the bodies of high-producing cows. Large amounts of energy and nutrients are utilized to synthesize milk; all body systems function intensely. Consequently, there are increased demands for adequate supply of energy and all nutrients including lipids. Insufficient or excessive intake of the latter leads to disruption of metabolism, lower productivity, and deterioration of animal health. At present, there is some controversy in the Russian and foreign literature in regard to on the optimal fat content in the dry matter of the rations of lactating cows, especially high-producing ones. Researchers recommend rather wide ranges of fat concentrations in the diets. The issue that remains insufficiently explored is the effect of various fat levels...
