Glutathione s-transferase in thought to play a key role in initiating the detoxication of potential alkylating agents, including pharmacologically active compounds. It is widely accepted that garlic contained allin which is converted to allicin by allinase. Allicin is easily degraded to diallyl disulfide and other components. This report attempted to observe the effect of diallyl disulfide on some biological activities. It was observed that the activity of serum transaminase was not changed by the treatment of diallyl disulfide. The liver cytosolic glutathione s-transferase was significantly increased. where as the microsomal glutathione s-transferase was not increased.

During the biological screening of Chinese drugs, it was found that alcoholic extract of the roots of Patrinia scabiosaefolia (Valerianaceae) caused a significant prolongation of hexobarbital-induced sleeping time and elevation of serum transaminase activities accompanied by severe histopathological changes in the hepatic tissues in mice on three day pretreatments. The systematic fractionation of the methanol extract monitoring by bioassay led to isolation of toxic saponins such as $3-O-{\alpha}-{_L}-arabinopyranosyl$ hederagenin $28-O-{\beta}-{_D}-glucopyranosyl\;(1{\rightarrow}6)-{\beta}-{_D}-glucopyranoside$ and its 2'-acetate and $3-O-{\beta}-{_D}-glucopyranosyl\;(1{\rightarrow}3)-{\alpha}-{_L}-rhamnopyranosyl\;(1{\rightarrow}2)-{\alpha}-{_L}-arabinopyranosyl$ oleanolic acid and its $28-O-{\beta}-{_D}-glucopyranosyl\;(1{\rightarrow}6)-{\beta}-{_D}-glucopyranoside$.

Recently, waste plastic recycling technology is transforming from Incineration system to pyrolysis gasification system which can derive the resources from environmental waste and charge no more environmental burden to nature. The present study was carried out to investigate the potential acute toxicity of derived product of pyrolysis gasifications system for recycling of waste plastic by a single oral dose in Sprague-Dawley Rats. In order to evaluate the hepatotoxic effects of derived product of pyrolysis gasification system, activities of serum transaminase were measured in rats. No related changes in survivals, clinical signs and the ratio of the liver to body weights of rats were monitored. The results showed that the single oral administration of material of pyrolysis system for recycling of waste plastic did not induce any toxic effect at orally single dose level of 0 and 100, 200, 400, 800mg/kg body weight in rats. We could not find out any significant tocxicity induced by single oral administrate of material of pyrolysis system for recycling of waste plastic.

The effect of lxeris sonchifolia H.(godulbaegi) on lipid metabolism were studied in S. D. rats. Twenty four rats were divided into four groups and fed diets containing 1 % cholesterol, 0.25% sodium cholate, 10% coconut oil and 5% lard(control group)f for 3 weeks. An experimental diet group was added with 5% leaf(PL group) or root powder(PR group) of godulbaegi. The lipid components and enzyme activites of serum and liver were assayed. The concentrations of total cholesterol, triglyceride and phospholipid were significantly lower in the PL and PR groups than in the control group. The levels of HDL-cholesterol were not significant but showed somewhat higher values in the PL and PR groups compaired with the control. The activities of glutamic oxaloacetic transminase(GPT) and glutamic pyruvic transaminase(GPT) were significantly lower in the PL and PR groups compaired with the control. In view of these results Godulbaegi is expected to be an effective food in preventing and improving the hyperlipidemic state.

The effects of various fractions from the whole plant of Pelvetia siliquosa Tseng et Chang (Fucaceae) on the $CCl_4$-induced hepatotoxicity as well as on streptozotocin (STZ)-induced diabetes in rats were investigated. The ether fraction exhibited a potent rat lens aldose reductase (RLAR) inhibition in vitro and showed a significant inhibition of not only serum glucose concentrations but also sorbitol accumulations in the lens, red blood cells and sciatic nerves in the STZ-induced diabetic rats. When administered orally in Sprague-Dawley rats, $H_{2}O$ fraction was found to cause a significant inhibition of the rise in the serum transaminase activities in $CCl_4$-intoxicated rats. These results suggested that this plant might possess constituents with hepatoprotective, anti-diabetic effects and those effects on diabetic complications.

Ketoconazole is an imidazole antifungal agent which inhibits the biosynthesis of fungal cellmembrane ergosterol and has immunosuppressive properties in vitro. Biphenyl dimethyl dicarboxylate (PMC) has been utilized for antioxidative action and for liver-protective purposes. Studies were undertaken to investigate effects of biphenyl dimethyl dicarboxylate (PMC) on the immunosuppression of ketoconazole in ICR mice. In the combination of PMC and ketoconazole, as compared with the treatment of ketoconazole alone, there were significant increases in activities of natural killer (NK) cells and phagocytes along with circulation leukocytes. The elevation of serum glutamic-pyruvic transaminase (S-GPT) and total protein levels caused by ketoconazole were reduced by the combination of PMC and ketoconazole. In addition, lower serum albumin and albumin/globulin (A/G) ratio were also increased to normal level.

Chlorination of the polluted water may produce odoriferous and objectionable-tasting chlorophenols which are hazardous to health. These studies were undertaken to investigate the hazardous effects of chlorophenols to the rat. 1. The chlorophenols such as o-chlorophenol and 2,6-dichlorophenol inhibited rat growth and caused increment of the ratio between liver weight and body weight. 2. The hemoglobin content, hamatocrit ratio and A/G of rat blood were decreased by chlorophenols administration. The activities of alkaline phosphatase, lactic dehydrogenase (LDH) and glutamate oxaloacetate transaminase (GOT) in serum as well as in liver were increased provisonally and decreased after one or two weeks adminstration. 3. The liver mitochondrial respiration ($QO_{2}$) was inhibited by chlorophenols treatment in in-vivo and in-vitro test. 4. The liver microsomal cytochrome P-450 was decreased by chlorophenols administration 5. Liver tissue was degenerated with congestion, atrophy, swelling, vacuolation, dilation of rough endoplasmic reticulum and denature of mitochondrial particle with swelling, and cristal destruction by chlorophenols adminstration. 6. After one and two weeks of adminstration of chlorophenols to rat, the aberrations of bone marrow chromosome and inhibition of its mitosis were observed respectively.

This study has been carried out to understand the effect of Danchisoyosangagambang (DC) on the hyperglycemic mice induced with streptozotocin(STZ). Experimental groups were made diabetic mice by intraperitoneal injection of STZ(60 mg/kg of body weight) tw ice by 24 h interval and then 120 mg/kg STZ was injected again 3 days after the earlier treatment. Control group was administered mice with 0.9 % saline(2 mL/kg), and experim ental groups were administered DC extract(DCA group, 10 mg/kg/day; DCB group, 30 mg/kg/day) after hyperglycemic induction for 6 weeks. The body weight of experimental groups was lower than control. The blood glucose concentration increased continuously, rea ching to 298.9 mg/dL after 6 weeks, however, experimental groups of the DCA and DCB groups significantly(p<0.0l) decreased in the 4, 5, and 6 weeks groups. Blood glucose tolerance test was not significant between control and experimental groups. We examined the blood transaminase activities to know the effect of herbal medicine on liver function. The GOT activities were lower in group DCB than in control. The GPT activities were lower in group DCA and DCB than in control. The content of triglyceride was significantly increased in group DCA compared to control. The SOD and catalase activities were higher in the group DCA compared to control. The results of immunohistochemical study, a few of insulin positive cells observed in the control and experimental group. These results suggest that administration of DC extract to the hyperglycemic mice decreased the blood glucose level.
