Aim of the current study was to evaluate the efficacy of non polar extract (NPE) of Aloe vera gel (AVG) for 60 days (~25μg/daily/orally) in rodent model of polycystic ovarian syndrome (PCOS). After treatment, steroid hormones and insulin levels were estimated by ELISA, serum lipid profile along with ovarian steroidal enzyme activity. Also, transcript as well as protein level of key receptors and steroidogenic enzymes were evaluated. Parallely, pairs of ovaries were excised and stained with Hematoxylin and Eosin (HE) to monitor the structural changes from group of animals. During course of study, stability of non polar extract (NPE) of AVG was evaluated by High Performance Thin Layer Chromatography (HPTLC) during study (15, 30, 45, 60 days). PCOS rats after treatment with NPE demonstrated a decrease in serum testosterone and insulin level with improved estradiol and progesterone levels. Also, decrease in transcripts level of steroid receptors while increased aromatase expression were observed after NPE treatment. These genes expression study was correlated with relative changes were observed with protein expressions....

The aim of this work is to prepare self-micro-emulsifying drug delivery system (SMEDDS) for oral bioavailability enhancement of a poorly water soluble drug, Pitavastatin. Solubility of Pitavastatin was determined in various vehicles. SMEDDS is mixture of surfactants, oils and co-surfactants, which are emulsified in aqueous media under conditions of digestive motility and gentle agitation that would be take place in the gastro-intestinal (GI) tract. Pseudo-ternary phase diagrams were made to detect the efficient self-emulsification region and particle size distributions of the resulting micro-emulsions were resolute using a laser diffraction sizer. Optimized formulations for in vitro dissolution and bioavailability assessment were Capmul PG 8, Tween 80 and Transcutol P. The release rate of Pitavastatin from SMEDDS have significantly higher than the conventional tablet. These suggest the superiority of prepared SMEDDS of Pitavastatin calcium for In-vitro drug release that may further in enhancement of bioavailability. Our studies illustrated the prospective use of SMEDDS for the delivery of hydrophobic compounds, such as Pitavastatin by the oral...

This study was designed to determine the extent of photolytic degradation of diazepam tablets, without light-protective packaging, available in the market. The UV spectroscopy method was designed and applied for this purpose. A total of 2160 tablets (each tablet contained 5 mg diazepam) of three different brand formulations A, B and C were chosen randomly. These tablets were then exposed to different indirect and direct lighting conditions i.e. normal room light condition (for 60 days), direct sunlight exposure (6 hours per day for 3 days), 25 Watt incandescent light bulb exposure and 40 Watt incandescent light bulb exposure (6 hours per day for 3 days). Samples from these light exposures were analyzed for potency determination using UV spectrophotometer and compared against the tablets kept in dark place (Control). Tablets of all three formulations showed marked degradation. The overall average degradations were 23.64%±5.53%; 28.36%±4.87%; 19.72%±4.83% and 25.40%±4.17% respectively for normal room light, direct sunlight, 25 Watt and 40 Watt incandescent bulbs whereas tablets kept in dark place showed little or...

Allium sativum (A. sativum), commonly known as garlic, is a species in the onion genus, Allium. The hypolipidemic activity of A. Sativum (Family: Amaryllidaceae) extract have been studied in alloxan-induced diabetic rats. In this model oral administration of extract (500mg/kg bw., p.o.) for 15 days in diabetic-dyslipidemic rats exerted significant lipid lowering effect as assessed by the reversal of serum levels of total cholesterol, phospholipids, triglyceride, free fatty acids, protein and lipid peroxide. The decrease of lipids and apoprotein levels of Very Low Density Lipoprotein and Low Density Lipoprotein were followed by stimulation of plasma post-heparin lipolytic activity as well as lecithin cholesterol acyltransferase, hepatic superoxide dismutase, catalase, triglyceride lipase and lipoprotein lipase activities with increase in reduced glutathione. Lipid and apoprotein level of High Density Lipoprotein were also recovered partially on treatment with A. sativum extract. The results of the present study demonstrated antidyslipidemic and antioxidant activities in A. sativum extract which could be used in prevention of diabetic dyslipidemia and related complications. The hypolipidemic activity of A....

The persent study was designed to investigate the anxiolytic activity of ethanolic extract of Leptadenia reticulata plant. It is a folk medicine traditionally used in treatment of eye diseases, seminal debility, general weekness, cough, fever, asthma, sore throat and gonorrhea. The anxiolytic activity was evaluated by Elevated plus maze Test, Light-Dark Test, Hole-board Test and Social-intraction Test models by using Wistar albino rats. The extract at oral dose 200mg/kg and 400mg/kg at body weight significantly increased time spend and no of entries in open arms in Elevated plus maze test and time spend in light area in light-dark test and no of head dipping in hole board test and also inceased social interaction time in social interaction test as compard to control animals. The effect was compared to the Diazepam (2mg/kg i.p.) as standard anxiolytic drug. The result of study indicate that the Leptadenia reticulata plant have potant anxiolytic...
