RESUMEN
To investigate the effects of Baoganning on injury of liver cells induced by hydrogen peroxide (H 2O 2) in rats.Rat models of injury of liver cells were induced by H 2O 2 at final concentration of 2 mmol/L. Six kinds of suspension of isolated rat liver cells were prepared according to the addition of serum. They were group A ( blank control), group B (H 2O 2 model), group C (normal control), group D (vitamin E), group E (low dosage of Baoganning) and group F (high dosage of Baoganning). Superoxide dismutase (SOD) activity, nitric oxide (NO) and malonyl dialdehyde (MDA) contents and glutamic pyruvic transaminase (ALT) level were detected.SOD activity and NO and MDA contents were increased and ALT level was decreased in Baoganning groups.[Conclusion]Baoganning exerts a protective effect on injury of liver cells induced by H 2O 2 in rats.
RESUMEN
Objective To explore the mechanism of Borneolum combined with Rhizoma Chuanxiong in counteracting cerebral ischemia with reperfusion injury.Methods Rat Model of cerebral ischemia with reperfusion injury was set up by occlusion of bilateral carotid arteries.The effect of Borneolum combined with Rhizoma Chuanxiong on the content of nitric oxide(NO)and free radicals of model rat brain tissue was observed.Results Borneolum combined with Rhizoma Chuanxiong decreased the lipid peroxide(LPO)content and increased the activity of superoxidase(SOD)in model rat brain tissue(P
