Systemic taurine prevents brain from lipopolysaccharide-induced lipid peroxidation in rats
Lipopolysaccharide (LPS), the major component of the outer membran of Gram-negative bacteria, can reproduce neuroinflammation and leads to oxidative stress in brain. Becausetaurine exhibits antioxidative properties, in this study, we aimed to evaluate the protective effects of taurine at the subtoxic dose of lipopolysaccharide-induced lipid peroxidation and oxidative stress. We measured malondialdehyde (MDA),...

A pharmaco-epidemiological survey of commonly used veterinary drugs in Southern Nigeria
A pharmaco-epidemiological survey was carried out on the commonly used veterinary drugs in Nigeria. This study was necessitated by the dearth of information regarding the side effects of the commonly used veterinary drugs in Nigeria. It has been noticed that most of the drugs used in the country were imported from developed countries. Though the drugs have been tested for side effects, it has not taken into cognizance...

Improving the physicomechanical properties of psyllium husk and evaluation its ret+arding properties on a water-soluble model drug
Psyllium is a natural polysaccharide which is administered as bulk laxative. This study wasundertaken to investigate psyllium's physicomechanical properties and also evaluation of its retardant properties. Several formulations containing variable amounts of psyllium and excipients examined to achieve optimized formulations. Then flowability, friability and hardness of prepared formulations were studied. Ultimately...

Postprandial hypolipidemic and hypoglycemic effects of Allium hertifolium and Sesamum indicum on hypercholesterolemic rabbits
Oxidative stress associated with postprandial hyperlipidemia contributes to endothelial dysfunction, which shifts hemostasis to a more thrombogenic state. The present study was undertaken to evaluate the effect of Allium hertifolium and Sesamum indicum on postprandial lipemic, glycemic profile and endothelial markers in hypercholesterolemic rabbits. A total of 32 male rabbits were randomized...

Roles of toll-like receptor 4 and immunomodulatory hormones in bovine endometritis
The aim of the study is to explore the role of Toll-like receptor 4 (TLR4) and immunomodulatory hormones in bovine endometritis. The bovine endometrial epithelial cell model (BenEpC) was used in the study. After contamination by Escherichia coli, BenEpCs were randomly divided into several groups according to the different concentration of 17-β estradiol (E2) treatment and the different stimulation,...

In-vitro pharmacological study and preliminary phytochemical profile of Viola canescens Wall. Ex Roxb
The crude ethanolic extract of Viola canescens whole plant was evaluated for their analgesic, gastrointestinal motility and preliminary phytochemical profile. The analgesic effect was assessed in mice, using acetic acid induced writhing test at a dose of 50, 100 and 200 mg/kg; the effect on GIT motility was tested in mice using activated charcoal as marker, as due to its black color the distance traveled in...

Quantitative determination of diosgenin in Dioscorea zingiberensis cell cultures by microplate-spectrophotometry and high-performance liquid chromatography
Quantitative determination of diosgenin was carried out by multi-well microplate-spectrophotometry and high-performance liquid chromatography (HPLC) in this study. Diosgenin detection by microplate-spectrophotometry depended on the formed yellow substance developed by perchloric acid, and measured at 410 nm. The calibration graph was linear over the range of 2 to 10 μg diosgenin in each well with correlation...
