Effects of ($\pm$)-camphor on liver cytochrome P450 enzymes were investigated in male ICR mice. Mice were treated intraperitoneally with 0, 200, 400 and 800 mg/kg of ($\pm$)-camphor in corn oil for 3 consecutive days. Twenty four hr after the final treatment, the animals were subjected to necropsy. The activities of serum aspartate aminotransferase and serum alanine aminotransferase were slightly changed by the treatment with ($\pm$)-camphor at the doses used. Administration of ($\pm$)-camphor to mice significantly induced the hepatic activities of pentoxyresorufin O-depentylase and benzyloxyresorufin O-debenzylase and weakly induced ethoxyresorufin O-deethylase in dose-dependent manners. The present results suggested that ($\pm$)-camphor might act as a relatively specific inducer of hepatic cytochrome P450 2B in male ICR mice.

이 증례는 드물게 보는 경우로 simvastatin과 gemfibrozil을 오랫동안 함께 복용했음에도, 특이한 문제가 발현되지 않았지만, 이들을 warfarin와 함께 치료하는 경우, 아주 높은 alanine aminotransferase (ALT), aspartate aminotransferase(AST) 혈중 농도, rhabdomyolysis, 급성 신장 장애가 발생하였다. 그 후, Simvastatin와 gemfibrozil을 복용 중단시켰더니, ALT/AST는 빠르게 정상수치로 돌아온 경우이다. 이 증례 보고서는 의료인들에게 simvastatin과 gemfibrozil을 함께 혹은 따로 warfarin과 함께 복용시켜 치료할 경우, creatine phosphokinase (CPK) 와 creatinine 혈중 수치들을 포함하여 ALT/AST 농도들을 주의 깊게 모니터하도록 경각심을 주고자 한다.

Heavy metals like Mercury and Cadmium cause various kinds of toxicities in the organs of Liver and Kidney. To observe the results of toxicity in the liver, kidney, and serum when the rats were injected subcutaneously with HgCl$_2$ and CdC1$_2$ and sacrificed after 24 hours and 72 hours from the last injection, we measured variation of lipidperoxide values in rat liver homogenate, variation of aspartate aminotransferase and alanine aminotransferase in rat serum. Variation of lipidperoxide values in rat kidney homogenate and variation of BUN in rat serum. It was found that Mercury and Cadmium administered subcutaneously to the skin in the air could cause the damages of liver and kidney.

An aqueous extract of oriental herbal composition named Onchengyeum and curcumin, an antioxidant isolated from turmeric (Curcuma Zonga L.) reduced hepatotoxicity induced by carbon tetrachloride ($CCI_4$). Improved liver function was observed by measuring the activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), blood urea nitrogen (BUN), creatinine (CRE), total cholesterol (T-CHO), triglyceride (TG), low density lipoprotein cholesterol (LDL-CHO), high density lipoprotein cholesterol (HDL-CHO), total protein (TP), albumin (ALB) and total bilirubin (BIL) in serum. Hepatic parameters monitored were levels of cholesterol (CHO), triglyceride (TG), and malondialdehyde (MDA) and activities of cytochrome P450 (CYP), NADPH-CYP reductase, superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), glutathione S-transferase (GST), glutathione reductase (GR), and glutathione peroxidase (GPx). The histopathological examination showed that the treatment of Onchengyeum and curcumin relieved the ballooning degeneration of hepatocytes which had been generated by $CCI_4$. The results suggested that hepatoprotective effects of Onchengyeum and curcumin possibly are due to their promising antioxidative activity.

The effect of treatment with pine needle oil complex (complex of pine needle oil and Korean medicinal herbs) upon rat hepatocytes exposed to alcohol was investigated. We compared body weight gain and ratios of liver and kidney to body weight and the serum biochemistry of rats administered both alcohol and Pine needle oil complex to control rats treated with alcohol alone. Pine needle oil complex treatment resulted in a significant reduction in the levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and triglycerides (TG) compared to the control rats. These data suggest that Pine needle oil complex represents an excellent candidate for protection of rat hepatocytes from alcohol-mediated damage.

The present study was carried out to find the possible protective effects of Angelica koreana water extract on biochemical parameters in benzo(a)pyrene (B(a)P)-induced liver injury in rats. B(a)P treatment (0.1 mg/kg, 1.p.) caused a liver damages, which led to biochemical alterations in serum and liver enzyme activities and serum lipid levels. The activities of liver marker enzymes, especially, aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) were markedly changed in B(a)P treatment. Oral administration of Angelica koreana (50 mg/kg) recovered these biochemical Parameters to near normal levels. Therefore, the present results have revealed that Angelica koreana water extract might have the antihepatotoxic effect and consequently ameliorate liver damage associated with B(a)P in rats.

In order to investigate the effects of Yukmijihwang-Tang on the hepatic microsomal function of Cd-poisoned rats, 3 mg/kg of cadmium (Cd) and 500 mg/kg of Yukmijihwang-Tang extract (YJT), a herbal hepatoprotective medicine, were administered concurrently to rats for 4 weeks. The levels of protein, aniline hydroxylase (AH) and malondialdehyde (MDA) were increased in Cd-treated group. This increase was suppressed by treatment or YJT. The levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), glucose-6-phosphatase (G-6-P) and ${\delta}-aminolevulinic$ acid dehydratase (ALAD) of Cd-treated group were decreased. This decrease was inhibited by treatment of YJT. Treatment with YJT significantly protects cadmium-induced hepatotoxicity.

Dibutyl phthalate (DBP) is used extensively in the plastic industry and has been known as an endocrine disruptor. Present study was undertaken to examine whether DBP can induce oxidative stress in mice. In this study, oxidative stress was measured in terms of the modification of lipid peroxidation and gamma-glutamyl transferase (GGT) activity. The serum toxicity index, level of lipid peroxidation and triglyceride (TG), and activity of GGT were measured in male ICR mice after a single administration of DBP (5 g/kg, po). DBP did not alter serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine, glucose and cholesterol level. However, the treatment with DBP was found to significantly increase the level of lipid peroxidation in liver and lung. The TG content and activity of GGT in the liver of DBP-exposed animals was also increased. These results indicate that DBP can induce mild oxidative stress in mice. The GGT activity is considered to be increased as one of the adaptive defense mechanisms to oxidative stress induced by DBP.

The contents and the compositions of total free amino acids were investigated in the rice(Oryza sativa L. cv. Chuncheong) seedlings under low temperatures. Activities of some enzymes associated with the markedly changed amino acid content were also investigaetd. Under low temperature, the contents of soluble protein and the total free amino acids increased, while the content of total nitrogen decreased. Although asparagine＋glycine were the most abundant amino acid speceis in the rice seedlings at the control temeprature, low temperature treatment for 3days brought about the decrease in their amount to about 60% level of the control plants. On the other hand, alanine showed the highest increase in the content among all the free amino acids, though glutamine, proline, asprtic acid, valine and tyrosine also increased after low temperature treatment. To eludicate the decrease of asparagine＋glycine level under low temperature, the activities of asparagine aminotransferase and asparaginase which metabolize asparagine were investigated in the rice seedlings under low temperature. The activity of asparaginase increased markedly, while that of asparagine aminotransferase decreased under low temperatures. Therefore, it was suggested that asparaginase metabolizes asparagine predominatly in the rice seedlings under low temperatures.

The protective effect of Bifidobacterium breve K-110, K-111 and B. infantis K-525 on carbon tetrachloride induced hepatotoxicity in rats was investigated. Among them, B. infantis K-525 had the most potent hepatoprotective activity. It reduced serum aspartate aminotransferase and alanine aminotransferase levels to 51% and 80% of the $CCl_{4}-treated$ groups, respectively. In rat liver homogenate intoxificated with $CCl_{4}$, B. infantis K-525 inhibited in vitro as well as in vivo lipid peroxidation more than the other Bifidobacteria.
