It is well known that oxidative stress of reactive oxygen species(ROS) may be a causative factor in the pathogenesis of bone disorder. The purpose of this study was to evaluate the cytotoxicity of oxidative stress. Cell viability by MTS assay or INT assay, activity of glutathione peroxidase(GPx), lipid peroxidation(LPO) activity and cell viablity. And also protctive effect of glutamate receptors against ROS-induced osteotoxicity was examined by protein synthesis, alkaline phosphatase (ALP) activity and lactate dehydrogenase (LDH) activity in cultured rat osteoblasts and osteoclasts. XO/HX decreased cell viability and GPx activity, protein synthesis and ALP activity, but increased LPO activity and LDH activity. In the protective effect, N-methyl-D-aspartate (NMDA) receptor antagonists or AMPA/kainate receptor antagonists such as D-2-amino-5-phosphonovaleric acid (APV), 7-chlorokynurenic acid (CKA), 6-cyano-7-nitroquinoxaline-2,3-dione (CNQX) and 6,7-dinitroquinoxaline-2,3-dione (DNQX), NMDA receptor antagonists but AMPA/kainate receptor antagonists showed protective effect on xanthine oxidase (XO) and hypoxanthine (HX) in these cultures by the increse of protein synthesis, ALP activity.

Objective : This study was undertaken to determine if Plantaginis Semen Aquacupuncture(PSA) has a protective effect against $CCl_4$ induced Hepatoxicity in Rats. Methods : The experimental group were divided into Normal group(untreated group), Control group, PSA group. Rats were administered orally $CCl_4$(0.1 ml/kg) for 4 days. In experiments for PSA effect, rats received 0.1 ml of PSA extraction in both sides of corresponding $G{\bar{a}}nsh{\bar{u}}$(BL18) of human body for 3 days after treated $CCl_4$. Variation of weight and biochemical assays(GOT, GPT, LDH, ALP, total cholesterol, triglyceride, albumin) were performed. Results : In Control group, $CCl_4$ increased serum GOT, GPT, LDH, ALP and albumin and decreased weight, total cholesterol and triglyceride. PSA significantly decreased serum GOT, GPT, LDH and increased total cholesterol as compared with Control group. Conclusion : These results indicate that PSA could be used in prevention and treatment of hepatoxicity. However, precise mechanisms of PSA protection remain to be determined.

The anticancer potency of the ethanolic extract of Terminalia arjuna on N-nitrosodiethylamine (DEN) induced hepatocellular carcinoma in Wistar albino rats was studied. Single intraperitoneal injection of DEN was administrated to induce liver cancer. After two weeks, phenobarbital (PB) was given orally for fourteen weeks to promote the cancer. The cancer bearing animals treated with ethanolic extract of T.arjuna (400 mg/kg body weight) for 28 days. Nucleic acids such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) were estimated in liver and kidney of control and experimental animals. Certain marker enzymes viz, alanine aminotransaminase (ALT), aspartate aminotransaminase (AST), acid phosphatase (ACP), alkaline phosphatase (ALP), 5'-nucleotidase (5'ND) and lactate dehydrogenase (LDH) were assayed in serum, liver and kidney of control and experimental animals. The levels of DNA and RNA were significantly increased in cancer bearing animals. The activities of ALT, AST, ACP, ALP, 5'ND, and LDH were significantly (P<0.001) increased in serum of cancer bearing animals. On the other hand, the levels of ALT, AST were decreased (P<0.001) and ACP, ALP, 5'ND, and LDH were significantly increased (P<0.001) in liver and kidney. These changes were reversed to near normal in drug treated animals. These observations suggest that the ethanolic extract of T.arjuna possess anticancer activity.

The protective effects of Rubus coreanum Miquel (RCM) extract against LPS-induced hepatotoxicity were studied in rats. Squrague-Dawley rats were intraperitoneally administered the RCM at 100 mg/kg per day for three weeks. Then single dose of LPS (5 mg/kg) was injected into rats. Four hours later, they were anesthesized with ether and dissected. We examined the levels of glutamate oxaloacetate transaminase (AST), glutamate pyruvate transaminase (ALT), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) in sera, superoxide dismutase (SOD) in mitochondrial fraction and catalase (CAT), glutathione peroxidase (GPx) in liver homogenate. LPS-treatment markedly increased the levels of AST, ALT, ALP, LDH and significantly decreased those of SOD, CAT and GPx. But RCM-pretreatment decreased the levels of AST, ALT, ALP and LDH by 57.9%, 37.4%, 62% and 69% respectively and increased those of SOD, CAT and GPx by 82.9%, 64.2% and 96.7% respectively. Subsequently, the protective effects of RCM was evaluated through histopathological examination of liver tissue. The LPS treatment increased the state of necrosis and cirrhosis surrounding the central veins (CV) and sinusoid, but RCM-treatment decreased the state of necrosis and cirrhosis in the liver tissue. These results demonstrated that protective effects of RCM against LPS-induced hepatotoxicity.

본 실험은 N-nitrosodiethylamine(NDEA)와 사염화탄소 ($CCl_4$)로 유발된 흰쥐의 간암 생성에 대한 인진호탕의 효과를 조사하였다. 실험은 8주 동안 실시하였고, 세 군으로 분류하였다. 정상군(Nor), 간암을 유발한 대조군(Con), 간암 유발 후 인진호탕 추출액(260 mg/kg/day)을 투여한 실험군 (IJH)으로 구분하였다. 체중은 정상군에 비하여 대조군에서 유의적으로 감소하였지만 실험군에서는 증가하였다. NDEA로 유발된 흰쥐의 혈청 AST, ALT, LDH, ALP와 AFP의 수준은 증가하였다. 반대로, 인진호탕 추출액을 처리했을 때, 혈청 AST, ALT, LDH, ALP와 AFP의 수준이 감소하였다. 흰쥐의 간에서 bcl-2 mRNA의 수준은 대조군에 비해 실험군에서 증가되었다. 그러나 c-myc mRNA의 수준은 대조군에 비해 감소하였다. 또한 NDEA로 손상된 간세포 조직의 공포화가 인진호탕 추출액의 투여로 감소하는 것을 관찰 할 수 있었다. 이상의 결과로 보아 인진호탕 추출액 투여가 NDEA와 사염화탄소로 유도된 흰쥐의 간암 생성을 억제 또는 지연하는 것으로 사료된다.
