Eight cattle and ten sheep were administrated various degree of PMA-B and EPN, and S-GOT, S-GPT and serum cholinesterase activity were tested. Serum cholinesterase activity showed no typical tendency, however, S-GOT/S-GPT ratios were decreased by the administration of PMA-B. It was suggested some degree of liver damage by the administration of the chemicals was recognized.

In order to evaluate the protective effects of extracts of Mori cortex radicis on carbon tetrachloride-induced hepatotoxicity, glutamic oxaloacetic transaminase, glutamic pyruvic transaminase, lactic dehydrogenase, malondiadehyde values and glutathione S-transferase activity were measured in ICR mice. The activities of serum aminotransferase and the hepatic content of lipid peroxide after carbon tetrachloride-treatment were markedly increased than normal control but those levels were significantly decreased by the treatment of butanol fraction of Mori cortex radicis mathanol extract. Glutathione S-transferase activity was decreased by carbon tetrachloride than control, but that also inhibited by the treatment of butanol fraction of Mori cortex radicis methanol extract. These results demonstrate a possible hepatoprotective role of extract role of extract of Mori cortex radicis against ${CCl_4}-induced$ hepatoxicity in vivo.

Objective: This study was performed to examine whether the porcine glutamic-oxaloacetic transaminase 1 (GOT1) gene has important functions in regulating adipocyte differentiation. Methods: Porcine GOT1 knockout and overexpression vectors were constructed and transfected into the mouse adipogenic 3T3-L1 cells. Lipid droplets levels were measured after 8 days of differentiation. The mechanisms through which GOT1 participated in lipid deposition were examined by measuring the expression of malate dehydrogenase 1 (MDH1) and malic enzyme (ME1) and the cellular nicotinamide adenine dinucleotide phosphate (NADPH) content. Results: GOT1 knockout significantly decreased lipid deposition in the 3T3-L1 cells (p<0.01), whereas GOT1 overexpression significantly increased lipid accumulation (p<0.01). At the same time, GOT1 knockout significantly decreased the NADPH content and the expression of MDH1 and ME1 in the 3T3-L1 cells. Overexpression of GOT1 significantly increased the NADPH content and the expression of MDH1 and ME1, suggesting that GOT1 regulated adipocyte differentiation by altering the NADPH content. Conclusion: The results preliminarily revealed the effector mechanisms of GOT1 in regulating adipose differentiation. Thus, a theoretical basis is provided for improving the quality of pork and studies on diseases associated with lipid metabolism.

This study was performed to investigate the effect of Mori Folium and Crataegus pinnatifida leave extracts on liver damage induced by CC1$_4$ in rats. 30％ and 60％ methanol extracts of Mori Folium and Crataegus pinnatifida leaves were administered orally at the dose of 10 mg/kg on every day for 6 days and liver damage was induced by intraperitoneal injection of $CCl_4$ (0.4 ml/kg) on 6th day. 30％ Methanol extracts of Mori Folium treated group showed significant protective effect on hepatotoxicity with the lowest Glutamic Oxaloacetic Transaminase (GOT) and Glutamic Pyruvic Transaminase (GPT). The low density lipoprotein (LDL) levels of 30％ methanol extracts of Mori Folium and Crataegus pinnatifida leave and 60％ methanol extracts of Mori Folium treated groups were significantly lower than normal group, respectively. In particular, LDL level of 30％ Mori Folium extracts treated group was significantly decreased compared to $CCl_4$ treated group. These results support that Mori Folium and Crataegus pinnatifida leave extracts are hepatoprotective effects against hepatotoxicity induced by $CCl_4$.

Effects of forced physical exercise on the CCl4 hepatotoxicity were examined in adult female rats. Rats were treated with CCl4 (2 mmol/kg, ip) and introduced into a cylindrical cage rotating at 9 rpm for 20 min/hr for 6 hr. Eighteen hr following the termination of exercise serum sorbitol dehydrogenase (SDH), glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT) activities and glucose-6-phosphatase activity were determined as parameters for hepatotoxicity. Physical exercise inhibited the $CCI_{4-}$induced increases in SDH, GOT, GPT activity, and glucose-6-phosphatase activity were determined as parameters for hepatotoxicity.

The effects of dichloromethane (DCM) on carbon tetrachloride (CT) toxicity were examined in adult male rats. A concomitant treatment of rats with DCM (0.3, 0.6, 1.2 g/kg, po) significantly potentiated the hepatotoxicity of CT (1.0 g/kg, po) as determined by increase in serum GPT (glutamic pyruvic transaminase), GOT (glutamic oxaloacetic transaminase), and SDH (sorbitol dehydrogenase) activity 24 hr following the treatments. Serum LDH (lactate dehydrogenase) activity was increased by either DCM or CT treatment.
