Cyclosporine(CsA) is an immunosupressant drug widely used in post-allogeneic organ transplant to reduce the activity of the patient's immune system and so the risk of organ rejection. It has been studied in transplants of skin, heart, kidney, liver, lung, pancreas, bone marrow and small intestine. Initially isolated from a Norwegian soil sample, Both kidney and liver dysfunction are prominent side effects of CsA. The present study was designed to determine the possible protective effect of salidroside(Sal) isolated from the BuOH extract of Acer termentosum Max against oxidative damage in CsA-treated(50 mg/kg, ip) nephrotoxicity rats. Results showed oral administration of methanol and butanol extact of Acer termentosum Max(200 mg/kg, po) significantly reduced activities of marker enzymes(BUN, Creatinine) and LDH activity in serum to CsA induced experimental kidney injured rats. And significantly decrcease of protein amount level in urine and activities of free radical formation enzyme were significantly improved by the treatment of Sal. And significantly decrcease of MDA level in kidney and activities of calalase, glutathione peroxidation and SOD were significantly improved by the treatment of Sal(20 mg/kg, po). But glutathione concentration and glutathione S-transferase actitity was not affected. Results of this study revealed that Sal could afford a significant protection in the alleviation of CsA-induced nephrotoxicity injury.

Acer tegmentosum Max which is one of the specialized wildness medicinal herbs in gangwon province, has been widely used for hepatitis, liver cirrhosis, hepatic cancer, leukemia, diabetes mellitus, renal necrosis and edema, etc. In this study, the antioxidative and hepatoprotective effects of in vitro and in vivo were investigated in order to evaluate the possibility as hepatoprotective agents. Oral administration of methanol and butanol extact of Acer tegmentosum Max to d-galactosamine (D-GaIN) induced experimental liver injured rats was significantly reduced activities of marker enzymes(AST, ALT) and LDH activity in serum. Salidroside(Sal) isolated from the BuOH extract of Acer termentosum Max potenty showed the scavenzing effect on DPPH and inhibitory effect on lipid peroxidation. And significantly decrcease of MDA level in liver and activities of SOD GSH-Px and catalase were significantly improved by the treatment of Sal. Results of this study revealed that Sal could afford a significant protection in the alleviation of D-GaIN-induced hepatocellular injury.
