Maduryung Extract, one of herbal medicine was tested for inhibitory effect to alcohol, acetaminophen and d-galactosamine induced hepatitis in rats. The results were as follows. 1. Increaced serum GOT, GPT levels by alcohol were significantly decreased by Maduryung extract.(p<0.01) 2. Maduryung extract decreaced GOT value in acetaminophen induced hepatitis and this effect may be due to increace of GSH level in liver tissue.(p<0.05) 3. Repeat administration of Maduryung extract showed inhibitory effect on s-GOT, s-GPT levels in d-galactosamine induced hepatitis. (p<0.05) According to the above results, it seems that Maduryung could be use as drug for alcohol or drug induced hepatitis treatment.

Objectives : The present study attempted to reveal the effects of the combination of Fel Ursi and Bezoar on the improvement of the function of the liver, through examining the effects of Fel Ursi, Bezoar, and Woong-Whang Tang composed of Fel Ursi and Bezoar. Method : Acute hepatitis was induced by galactosamine to rats, and then Fel Ursi, Bezoar Bovis, and Woong-Whang Tang were introjected to measure the influence of serums such as AST, ALT, ALP, ${\gamma}GT$, and lipid peroxide of liver tissues which are considered as the index of the function of the liver. Results : 1. Fel Ursi decreased the lipid peroxide of ALT, ${\gamma}FT$, and liver tissue and that of mitochondria in liver tissues of the rats with galactosamine-induced acute hepatitis, but it did not have any significant effect on AST and ALP. 2. Bezoar Bovis decreased the lipid peroxide of AST, ALT, ALP, ${\gamma}GT$, and the liver tissues among serum of the rats suffering from acute hapatitis induced by galactosamine, but it did not have any significant effect on that of mitochondria of the liver tissues. 3. Woong-Whang Tang had a significant effects on the lipid peroxide of AST, ALT, ALP, ${\gamma}GT$, and the liver tissues, and on the decrease of lipid peroxide of mitochondria, among serum of the rats suffering from acute hapatitis induced by galactosamine. Conclusion : Fel Ursi and Bezoar Bovis were judged to be effective on the acute hepatitis of the liver by galactosamine. In particular, Woong-Whang Tang which was composed of the combination of Fel Ursi and Bezoar Bovis was more efficient in the improvement of the function of the liver and the amount of lipid peroxide than the respective use of Fel Ursi or Bezoar Bovis.

The acute toxicity of CJ-50005, an inactivated whole virus vaccine derived from hepatitis A virus (HM175) grown in human MRC-5 diploid fibroblast culture, was tested in Sprague Dawley (SD) rats and beagle dogs. CJ-50005 was orally and intramuscularly administered up to the maximum dose of 81$\mu\textrm{g}$/kg. as much as 3,000 times of the expected clinical dose, in SD rats and was intramuscularly administered up to 27 $\mu\textrm{g}$/kg, as much as 1,000 times of the expected clinical dose, in beagle dogs. In these experiments, there were no death and clinical changes which were related to CJ-50005 administration. In addition, there were no significant changes between control and treated groups in body weights and autopsy findings. In conclusion, the administration of CJ-50005 over 81$\mu\textrm{g}$/kg in SD rats and over 27$\mu\textrm{g}$/kg in beagle dogs was proved to be safe, and it is thought that CJ-50005 may not show any toxicity in its clinical use.

Hepatitis, liver cirrhosis and liver cancer caused by viral infection are among the most prevalent causes of death in Korea. Several medicines have been in use despite their nonsatisfactory effects on these disease. Some herbal medicines put to use recently have not shown beneficial effects, either. This paper evaluates the effects of extracts from 10 traditional Korean herbal medicines on rats with hepatic damage induced by galactosamine. Rubus coreanus showed an anti-inflammatory effect as shown on the data of activities of serum transaminases.

SCi-B-Vac, the 3rd hepatitis B vaccine , was selected for clinical evaluation on the basis of toxicologic profiles in preclinical studies. These studies were performed to obtain information on its toxic signs, organs which are mainly affected, and to estimate its lethality in mice and rats given Sci-B-Vac through two routes of administratin. In male and female rats given a single intragastrical dose of Sci-B-Vac, we estimated that $LD_{50}$ values were over 2.00 ml/100g B.W. (10ng/ml), respectively.

A formula diet based on pork meat oligopeptides(pork meat protein hydrolysates) was designed for experimental hepatitic rats. The rats were given D-galactosamine for 6 days. During this period, the rats were provided with a 12% casein diet or the formula diet which was low in aromatic amino acids and rich in branched chain amino acids. The formula diet was prepared using pork meat oligopeptides as the principal nitrogen source. The hepatitic rats given the formula diet had lower plasma GOT and GPT concentrations. Additionally, the fischer ratio of the plasma was significantly lower in those rats. However, there was no significant difference in the plasma insulin-like growth factor-I concentration before and after acid-ethanol extraction among groups. These results suggest that the formula diet was better for the animals than the casein diet. Furthermore, these findings suggest that pork meat oligopeptides are an excellent material for preparation of formula diets for patients suffering from hepatitis.

CJC-50100 is a recombinant hepatitis B virus surface antigen (HBsAg) expressed in yeast. The general pharmacological properties of CJC-50100 were evaluated in mice, rats, dogs and isolated guinea pig ileum. The doses were 0.33~33.3 $\mu$g/kg i.m. for mice and rats and 3.3~9.9 $\mu$g/kg i.v. for dogs. The concentrations of 0.002~0.02 $\mu$g/ml were used for the assay with guinea pig ileum. Intramuscular administration of CJC-50100 at the doses did not alter general behavior and the responses for central nervous system, smooth muscle, gastrointestinal system, cardiovascular and respiratory system, and water and electrolytes excretion. In summary, CJC-50100 had no pharmacological effect in these studies even up to the 100-fold of the expected clinical dose, 20 $\mu$g/man/60 kg.

This study was undertaken to establish reliable diagnostic-procedures for the microbiological monitoring of laboratory animals. Murine(mice and rats) antibodies against hemagglutinating virus of Japan(HVJ), mouse hepatitis virus(MHV) and Mycoplasma pulmonis(Mp) were detected sensitively and specifically in experimentally and naturally infected animals' sera by an indirect enzyme-linked immunosorbent assay(ELISA), using urease conjugated antimurine immunoglobulin. The sensitivity and specificity of the complement fixation test which has been apllied widely for serodiagnosis of HVJ, MHV and Mp infections were apparently lower than those of ELISA. From these results, the ELISA was found to be available for the serodiagnosis of HVJ, MHV and Mp infections in mice and rats.

Gardenia jasminoides is a popular traditional herb used to treat inflammatory diseases including liver disorders. This study was performed to examine protective effect of G. jasminoides on galactosamine (GalN)-induced acute hepatitis. Rats were treated intraperitoneally with GalN (700 mg/kg). G. jasminoides (30, 100 and 300 mg/kg) was administered orally 48, 24, and 2 h before and 6 h after GalN injection. Serum ALT and AST activities were significantly increased after GalN injection, and these increases were attenuated by G. jasminoides. Histological studies showed that G. jasminoides inhibited hepatocellular necrosis with inflammatory cell infiltration. GalN decreased the serum levels of total cholesterol and this decrease was attenuated by G. jasminoides. Hepatic glutathione content was decreased and lipid peroxidation was increased after GalN treatment and these changes were attenuated by G. jasminoides. Furthermore, the level of tumor necrosis factor-${\alpha}$ mRNA expression was significantly increased after GalN injection, and this increase was attenuated by G. jasminoides. The level of interleukin-10 mRNA expression was significantly increased after GalN injection, and this increase was augmented by G. jasminoides. Our results suggest that G. jasminoides ameliorates GalN-induced acute hepatitis and this protection is likely due to antioxidative activity and regulation of inflammatory mediators.

Gamiinjinoryung-San is composed of eight crude drugs including Artemisiae capillaris Herba which is widely used for the treatment of acute jaundice, acute and chronic hepatitis at the Oriental hospital of Kyung-Hee Medical Center. This study was conducted to investigate the effects of water extract of Gamiinjinoryung-San on the liver function. The results obtained were as follows; the extract markedly reduced LDH and ALP activities, but slightly decreased GOT and GPT activities elevated with D-galactosamine in rat serum. The liver protective activities were shown in $CCl_4-intoxicated\;rats$. The extract prevented the prolongation of sleeping time in $CCl_4-intoxicated\;rats$. The bile flow and the biliary bile acid secretion were significantly increased in normal rats.
