Attenuation of myocardial injury by postconditioning: role of hypoxia inducible factor-1alpha.

Postconditioning (PostC) has regenerated interest as a mechanical intervention against myocardial ischemia/reperfusion injury, but its molecular mechanisms remain elusive. This study tested the hypothesis that hypoxia inducible factor-1alpha (HIF-1alpha) plays a role in PostC-induced cardioprotection. Male Wistar rats were subjected to 30 min ischemia followed by 3 h of reperfusion (Control).

Hepatoprotective role of Ganoderma lucidum polysaccharide against BCG-induced immune liver injury in mice.

Aim: To examine the effect of ganoderma lucidum polysaccharide (GLP) on the immune liver injury induced by BCG infection, and investigate the relationship between degrees of hepatic damage and NO production in mice.

Methods: Immune hepatic injury was markedly induced by BCG-pretreatment (125 mg.kg(-1), 2-week, iv) or by BCG-pretreatment plus lipopolysaccharide (LPS, 125 microg.
