These studies were carried out to observe the effect of Aqua-acupuncture with Woolgum extract on the recovery from liver injury of rats. The liver injury of rats induced with 0.5ml/200g carbon tetrachloride. The Aqua-acupuncture with Woolgum extract solution inserted into corresponding locus of the Kansu(BL18.) in Rats. Experimental group was divided into 4 groups: Normal group, $CCI_4$-intoxicated group, Saline treated group after $CCI_4$-intoxicated and Woolgum aqua-acupuncture treated group after $CCI_4$-intoxicated. Biochemical assays for each serum enzyme activity of GOT, GPT, LDH, total protein, triglyceride, albumin, WBC, neutrophils, lymphocyte were performed. The results were as follows : 1. GOT was decreased with statistical significance in the Woolgum aqua-acupuncture treated group after $CCI_4$-intoxicated. In GOT activity, the Woolgum aqua-acupuncture treated group after $CCI_4$-intoxicated showed higher level significant compared with the saline aqua-acupuncture treated group after $CCI_4$-intoxicated. 2. GPT was decreased with statistical significance in the Woolgum aqua-acupuncture treated after $CCI_4$-intoxicated. In GOT activity, the Woolgum aqua-acupuncture treated group after $CCI_4$-intoxicated showed higher level significant compared with the saline aqua-acupuncture treated group after $CCI_4$-intoxicated. 3. LDH was decreased with statistical significance in the Woolgum aqua-acupuncture treated group after $CCI_4$-intoxicated. 4. Total protein increased with statistical significance in the Woolgum aqua-acupuncture treated group after $CCI_4$-intoxicated. 5.

The prevalence of multi-drug resistant tuberculosis (MDR-TB), which is resistant to isoniazid and rifampin, has been increasing in Korea. And the side effects of 2nd line anti-tuberculosis medications, including drug-induced hepatitis, are well known. Although prothionamide (PTH) is one of the most useful anti-TB medications and although TB medication-induced acute hepatitis is a severe complication, there are only a few published case reports about prothionamide induced hepatitis. In this case report, a 22 year old male was diagnosed with pulmonary MDR-TB and was administered 2nd line anti-TB mediations, including PTH. Afterwards, he had a spiking fever and his liver enzymes were more than 5 times greater than the upper limit of the normal range. He was then diagnosed with drug-induced hepatitis by liver biopsy. His symptoms and liver enzyme elevation were improved after stopping PTH. Accordingly, we report this case of an association between PTH and acute hepatitis.

In order to investigate the protective effect of Samduhaejungtang on the liver injury of rats induced by $CCl_4$ and d-galactosamine, the serum transaminase(GOT& GPT), alkaline phosphatase(ALP), lactic dehydrogenase(LDH) for enzyme activities and triglyceride, total bilirubin amounts for serum component were measured. All animals were divided into 4 groups, those were normal group(untreated), control group(treated with vehicle 0.9% Saline solution), sample Ⅰ group(1000mg/kg administrated), sample Ⅱ group(2000mg/kg administrated). The results were as follows : 1. The inhibitory effects of the serum GOT activities in rats induced by $CCl_4$ were noted in both sample Ⅰ group(p<0.01) and sample Ⅱ group(p<0.001). In serum GPT activities, sample Ⅱ group(p<0.05) only showed the inhibitory effects. 2. The inhibitory effects of the serum ALP activities in rats induced by $CCl_4$ were noted in both sample Ⅰ group(p<0.01) and sample Ⅱ group(p<0.001). 3. The inhibitory effects of the serum LDH activities in rats induced by $CCl_4$ were noted in sample Ⅱ group(p<0.05). 4. The increases of the serum triglyceride content level in rats induced by $CCl_4$ were inhibited in both sample Ⅰ group(p<0.01) and sample Ⅱ group(p<0.001). 5. The increases of the serum total bilirubin content level in rats induced by $CCl_4$ were inhibited in both sample Ⅰ group(p<0.01) and sample Ⅱ group(p<0.001). 6. The inhibitory effects of the serum GOT& GPT activities in rats induced by d-galactosamine were noted in sample Ⅱ group(p<0.001), but sample Ⅰ group was not recongnized. 7. The significantly inhibitory effects of in the serum LDH activities in rats induced by d-galactosamine were note in sample Ⅱ group(p<0.05). 8. The increases of the serum triglyceride content level in rats induced by d-galactosamine were inhibited in sample Ⅱ group(p<0.01). 9. The increases of the serum total bilirubin content level in rats induced by d-galactosamine were inhibited in sample Ⅱ group(p<0.05). According to the above results, it is considered that Samduhaejungtang has protective effect against liver injury in rats induced by $CCl_4$ and d-galactosamine.

Modem people have begun to have the nationwide interest in the rice wine called Makgeolri which is one of the traditional Korean alcoholic liquors. This study was performed to investigate the effects of San sung Makgeolri extract (SM) on antioxidation together with the determination of pH and dissolved oxygen (DO) in the progress of fermentation in the lipopolysaccharide(LPS)-treated rats. We examined the levels of SOD (superoxide dismutase), CAT (catalase), GPx (glutathione peroxidase) in liver homogenates and the histopathological observations in liver tissue. LPS-treated group markedly decreased the levels of SOD, CAT and GPx. But SM + LPS-treated group significantly increased the levels of them. Furthermore, the antioxidative effects of SM were supported by the histopathological observations in liver tissue which showed severe inflammation and necrosis in LPS-treated group, compared to the attenuated inflammation and necrosis in SM + LPS-treated group. This results suggested that SM could be a candidate of antioxidative material in spite of alcoholic liquors.

This study was carried out to investigate functional activities of the free radical scavenging and germ of Glycin max. Merrill fur cytotoxicity toward P338 and L1210 cells derived from mouse. Effect of crude saponin were examined to oxygen radicals and their scavenger enzymes in liver fractions of Spragae-Dawley(SD) rats. Male rats were fed basic diets of control and experiment diets of 0.5∼1.0% crude saponin. There were no significant differences in hydroxy radical($.$OH) formation of liver mitochondria and microsomes in 1.0% group, while $.$OH formations were significantly decrease in 0.5% and 1.0% saponin compared with control group. Their oxygen radical(O$_2$$\^$$.$/) scavenging activities were significantly decrease in liver cytosol of 0.5% and 1.0% saponin group compared with control group. Soybean germ saponin was isolated purified by the method of HPLC to investigate the cytotoxicity of mouse cells by using the MTT assay. SA-1 saponin fraction of soybean germ showed to inhibit toward growth cell of P338 and L1210 cells and its showed less than 50% cytotoxicity These results suggest that the saponin may play a effective role in attenuating a oxygen radical formations and increasing a scavenger enzyme activities.

The present study was designed to determine long-term feeding effects of vitamin E and BHT (butylated hydroxytoluene) on serum biochemical profiles, organ weight, and intestinal and hepatic antioxidant enzymes including superoxide dismutase (SOD), glutathione peroxidase (GSH-PX), and glutathione-S-transferase (GST) in ICR mice. Four wk old ICR mice (n=8 per group) were fed the diets supplemented with vitamin E (I ; 0.03% and II ; 0.3%) and BHT (I ; 0.05% and II ; 0.5%) for 12 months. Feeding the diets containing vitamin E and BHT had no effects on growth and serum biochemical profiles. However, feeding the diets supplemented with 0.5% BHT for 12 months significantly increased liver weight of the mice. In the small intestine, there were no effects of vitamin E or BHT on SOD and GSH-PX activities in the mucosa. However, the activity of intestinal GST of the mice that received 0.5% BHT was almost twice as high as that of control mice. In the liver, the activity of SOD was not affected by feeding antioxidants for 12 months, whereas GSH-PX activity was significantly increased in mice that received the diets containing BHT (0.05%, 0.5%) and vitamin E (0.03%, 0.3%). In addition, supplementation of 0.5% BHT markedly enhanced hepatic GST activity compared with other groups. Enhanced activity of GSH-PX in response to feeding vitamin E or BHT might aid hepatic enzymes to eliminate active oxygen in organs from mice. However, we could not exclude the possibility of increased lipid peroxidation by high dosage of BHT supplementation. More detailed study is necessary for assessment of preventive or toxicological effects of high dosage of BHT supplementation.

This study was to compare the effects of dietary n-6 and n-3 fatty acids and fat unsaturation on plasma lipids and chemical composition of VLDL and LDL fraction and lipogenic enzymes activity in rat liver under the conditions providing 1) a similar amount of n-6, n-3 fatty acids(LA, ALA, EPA+DHA) in diets and 2) the various degree of fat unsaturation. Male Sprague-Dawley rats weighing 420g were treated for 6-n with six experimental diets providing 25% of energy as fat and which were different only in fatty acid composition. The fats used for a source of each fatty acid were beet tallow for saturated fatty acid corn oil for n-6 linoleic acid(LA) perilla oil for n-3 $\alpha$-linolenic acid(ALA) and fish oil n-3 eicosapentaenoic acid (EPA) and n-3 docosahexaenoic acid(DHA). Plasma cholesterol level was increased by corn oil to compare with beef tallow but was decreased by perilla oil or fish oil. Plasma TG level was significantly decreased by perilla oil or fish oil. Fish oil significantly reduced the level of HDL-Chol and the proportion of Chol in LDL fraction and that of TG in vVLDL fraction. Overall there was a singificant negative correlation between the level of each plasma lipid(Chol TG, VLDL-TG, LDL-C) and the degree of fat unsaturation. However this rerlationship is not always true when compared the hypolipidemic effect of each fatty acid at a similar level of fat unsaturation. There was a trend such taht glucose 6-P dehydrogenase 6-phosphogluconate dehydrogenase and malic enzyme activites were reduced by n-3 fatty acids. Perilla oil significantly increased the incorporation of c20:5 and c22:5 into liver tissue and fish oil suignificantly increased the incorporation of c20:5, c22:6 into liver tissue and the effect of long chain n-3 fatty acid incorporation was greater by fish oil. therefore the hypotriglyceridemic effect of n-3 fatty acid could be resulted from the interference of hepatic lipogenesis by long-chain n-3 fatty acids and the reduced proportion of TG in VLDL fraction and its effect was greater by n-3 EPA+DHA than n-3 ALA even though plasma Chol and TG levels were also influenced by the degree of dietary fat unsaturation.

Chronic exposure to cadmium (Cd) is known to adversely affect renal function. Our previous studies indicated that Cd induces p53-dependent apoptosis by inhibiting gene expression of the ubiquitin-conjugating enzyme (Ube) 2d family in both human and rat proximal tubular cells. In this study, the effects of Cd on protein expression of p53 and apoptotic signals in the kidney and liver of mice exposed to Cd for 12 months were examined, as well as the effects of Cd on p53 protein levels and gene expression of the Ube2d family in various cell lines. Results showed that in the kidney of mice exposed to 300 ppm Cd for 12 months, there was overaccumulation of p53 proteins in addition to the induction of apoptosis, which was triggered specifically in the proximal tubules. Interestingly, the site of apoptosis was the same as that of p53 accumulation in the proximal tubules. In the liver of mice chronically exposed to Cd, gene expression of the Ube2d family tended to be slightly decreased, together with slight apoptosis without the accumulation of p53 protein. In rat small intestine epithelial (IEC-6) cells, Cd decreased not only the p53 protein level but also gene expression of Ube2d1, Ube2d2 and Ube2d4. In human brain microvascular endothelial cells (HBMECs), Cd did not suppress gene expression of the Ube2d family, but increased the p53 protein level. In human brain astrocytes (HBASTs), Cd only increased gene expression of UBE2D3. These results suggest that Cd-induced apoptosis through p53 protein is associated with renal toxicity but not hepatic toxicity, and the modification of p53 protein by Cd may vary depending on cell type.

In order to develop tools for an early serodiagnosis of Plasmodium falciparum infection, we evaluated the usefulness of P. falciparum liver stage antigen-3 (LSA-3) as a serodiagnostic antigen. A portion of LSA-3 gene was cloned, and its recombinant protein (rLSA-3) was expressed in Escherichia coli and purified by column chromatography. The purified rLSA-3 and 120 test blood/serum samples collected from inhabitants in malaria-endemic areas of Mandalay, Myanmar were used for this study. In microscopic examinations of blood samples, P. falciparum positive rate was $39.1\%$ (47/120) in thin smear trials, and $33.3\%$ (40/120) in thick smear trials. Although the positive rate associated with the rLSA-3 $(30.8\%)$ was lower than that of the blood stage antigens $(70.8\%)$, rLSA-3 based enzyme-linked immunosorbent assay could detect 12 seropositive cases $(10.0\%),$ in which blood stage antigens were not detected. These results indicate that the LSA-3 is a useful antigen for an early serodiagnosis of P. falciparum infection.

This study was conducted to investigate of hepatoprotective effect of dandelion water extract (DWE) according to repeated administration of thioacetamide (TAA) induced hepatotoxicity in Spraque-Dawley rats. Thirty rats were randomly assigned to 5 groups; normal control, DWE-control, TAA-control (TAA injection during the feeding of normal diet), TAA&DWE600 (TAA repeated injection during the feeding of DWE 600 mg/kg BW), TAA&DWE1200 (TAA repeated injection during the feeding of DWE 1,200 mg/kg BW). Rats in DWE-control and TAA&DWE groups were treated with DWE (600 or 1,200 mg/kg BW daily) by gavage for 20 days (twice a day). All the rats in the TAA-control and TAA&DWE groups were repeated injection of TAA (100 mg/kg BW) into the abdominal cavity 3 days interval and 12 hrs later, all rats were sacrificed. At the same time, normal control and DWE-control groups were injected normal saline. In TAA&DWE groups, serum alanine and aspartate aminotransferase (ALT, AST) were significantly decreased and triglyceride (TG) synthesis was significantly increased compared to TAA group. As well as total billilubin and GGT were slightly decreased by the treatment of DWE. Lipid peroxidation (MDA) concentration was significantly decreased and hepatic GSH content was slightly or significantly increased in the TAA&DWE groups compared to TAA group. Hepatic anti-oxidative enzyme activities, such as GSH, GST, SOD and catalase were slightly or significantly elevated by the treatment of DWE. According to these results, When dandelion extract was long term supplied, it could be used as a potential protective material for a longer time liver damage by repeated adminstration of the TAA.
