Andrographolide protects against isoproterenol-induced myocardial infarction in rats through inhibition of L-type Ca and increase of cardiac transient outward K currents.

Myocardial infarction (MI) is the irreversible injury of the myocardium caused by prolonged myocardial ischemia and is a major cause of heart failure and eventual death among ischemic patients. The present study assessed the protective potentials of andrographolide against isoproterenol-induced myocardial infarction in rats. Animals were randomly divided into four groups: Control (Ctr) group received 0.

Oxidative indices correlate with dyslipidemia and pro-inflammatory cytokine levels in fluoride-exposed rats.

The aim of this study was to establish the effects of fluoride on lipid metabolism and attendant inflammatory response by exposing rats to 50 mg L(-1) and 100 mg L(-1) of fluoride through drinking water for seven weeks. Both concentrations led to hypercholesterolemia while the 100 mg L(-1) concentration induced hypertriglyceridaemia. High density lipoprotein (HDL) cholesterol levels dropped in the exposed rats while interleukin 2 (IL-2) increased more than 1.

In Vitro and In Vivo Biochemical Evaluations of the Methanolic Leaf Extract of Garcinia kola.

Garcinia kola Heckel (Guttiferae) leaves have received limited scientific attention despite their traditionally acclaimed medicinal properties. The scavenging ability of the methanolic leaf extract (MLE) of G. kola was assayed for hydroxyl radical (OH(•)), superoxide anion (O2 (-)), 1,1-diphenyl-2-picrylhydrazyl (DPPH), azinobis-3-ethyl-benzothiazoline-6-sulfonic acid (ABTS(•+)), and lipid peroxidation (LP) activity in egg yolk, rat liver, and brain homogenates.

Impaired lipid levels and inflammatory response in rats exposed to cadmium.

To investigate the subchronic effect of cadmium intoxication on lipid metabolism and the inflammatory responses accompanying it, rats were administered 50 and 100 ppm cadmium through their drinking water for 7 weeks. At both concentrations, cadmium exposure resulted in significant elevation (p < 0.05) of total cholesterol and gave rise to hypertriglyceridemia in the plasma of the animals.
