Objectives : This study was carried out to determine if Dendrobii Herba have protective effect against cell injury induced by various toxic agents in rat kidney slices. Water(DWe) and methanol(DMe) extracts were prepared for this experiment. Methods : Cell injury was estimated by measuring lactate dehydrogenase(LDH). Lipid peroxidation was examined by measuring malondialdehyde, a product of lipid peroxidation. Results : DMe prevented the LDH release by $CCl_4$, menadione, tert-butyl hydroperoxide and mercury treatment in vitro in kidney slices, but DWe prevented the LDH release by $CCl_4$ and mercury. DMe also prevented reduction in GSH and lipid peroxidation induced by $CCl_4$ and mercury. Conclusion : Thus, DMe may have more powerful efficacy on anti-oxidative effects when compared with DWe. And further studies have to be followed concerned with extraction of Dendrobii Herba and its change of effects.

Objectives : This study was carried out to determine if Scutellariae Radix have protective effect against cell injury induced by various toxic agents in rat kidney slices. Methods : Water(SWe) and methanol(SMe) extracts were prepared for this experiment. Cell injury was estimated by measuring lactate dehydrogenase(LDH). Lipid peroxidation was examined by measuring malondialdehyde. Results : SMe prevented the LDH release by CCl4, menadione, tert-butyl hydroperoxide and mercury treatment in vitro in kidney slices, but SWe prevented the LDH release by CCl4 and mercury. SMe also prevented reduction in GSH by CCl4 and lipid peroxidation induced by mercury. Conclusions : Thus, SMe may have more powerful efficacy on anti-oxidative effects when compared with SWe. And further studies have to be followed concerned with procedure of extraction of SMe and its change of effects.
