Objectives : The purpose of this study is to observe the anti-oxidative effects of electroacupuncture at Taegye($KI_3$) in rats. Methods : The methods are measures of experimental items including change of body weight, relative liver weight, level of alblumin, total bilirubin, LDL-cholesterol, LDH, GOT and GPT in blood serum, level of SOD, GSH, catalase, NO and MDA concentration in liver, histological change of liver. Results: 1. The $KI_3$-EA group lost weight in the beginning, and gained it gradually. 2. The liver ratio of the $KI_3$-EA group increased compared to the holder group, without any statistical significance. 3. The SOD activity, Glutathione concentration, and Catalase concentration increased, and the NO concentration and MDA concentration decreased in the $KI_3$-EA group significantly, compared to the holder group. 4. $KI_3$-EA group had more similar density to the normal group, than the holder group. Conclusion : The electroacupuncture application on Kb has anti-oxidation effect, by improving the body defence against the oxidation stress- induced cytotoxicity, and by supressing the oxidative liver damage.

Biologically, MGK-264 (N-octyl bicycloheptene dicarboximide) acts as a synergists for insecticides mainly pyrethrins and pyrethroids. It's used extensively in combination with pyrethrin and piperonyl butoxide and also with personal insect repellent and cockroach repellents. But the toxic effect of MGK-264 in mamalians was a relatively little known therefore in this studies it was initiated to examine the toxic effect of MGK -264 in rats. For 5 weeks it administrated daily in each 250 mg and 500 mg of MGK-264 per kg of body weight in rats. 1) The body weight gain and the LYMPH (%) value in blood were observed a slight tendency to reduce in accordance with amount of dose and number treatment time. 2) The content of cytochrome P-450 and activity of NADPH-cytochrome c reductase were decreased in liver and those were observed some tendency in the kidney as liver but not significant. 3) The liver cholinesterase activity in the both 250 mg/kg and 500 mg/kg per kg of body weight with treated groups and the liver aniline hydroxylase in 500 mg/kg treated group were gradually decreased from 4 weeks after treated groups. In consequence it would sugested that the toxic effect of MGK-264 was low but in could offer hazard effect in liver and nervers system of rats if it was administrated move dose of MGK-264 and agumented in number of treated time.

The purpose of this study is to investigate dietary factors which influence the conditions of Korean fatty liver patients. The subjects were 83 fatty liver patients living in city, ages of 10 to 60 yrs old, and they were the same patients studied 9 months ago in previous study. The patients were groupsed into 3 groups(improved, similar, worsened groups) according to the changes in disease condition. Nutrient and alcohol intakes and health status were investigated. In improved group, the patients tended to lose weight, the number of exercising patients was increased, the consumptions of calorie, carbohydrate, calcium, phosphorus were decreased. And alcohol intake was decreased markedly and serum total amino acids(AA), EAA, NEAA, BCAA and AMAA contents, EAA/NEAA and BCAA/AMAA ratios were increased. In worsened group, patients tended to gain weight, the number of exercising patients decreased, the consumptions of calorie, protein, carbohydrate, calcium, phosphorus and niacin decreased but vitamin. A intake increased. And also, in this group, alcohol intake of male patients decreased and that of female slightly increased, and serum EAA, BCAA and AMAA contents, EAA/NEAA and BCAA/AMAA ratios, and total fatty acid contents increased and total AA and NEAA contents decreased. In conclusion, it is desirable to reduced weight, stress, alcohol, salt and animal fat consumptions, and to exercise, and to take adequate amount and quality of protein to improve conditions of fatty liver patients.

To evaluate the effect of cyclohexane(CH) treatment on the liver cytochrome P-450 dependent aniline hydroxylase(CYPdAH) activity in alcohol-pretreated animals, CH(1.56 g/kg body weight) was intraperitoneally administered to Sprague-Dawley male rats, which had been drunk 15％ alcohol in distilled water for 1,3 and 6 weeks. CH was injected to rats 4 times every other day and the animals were sacrificed at 24 hours after injection of CH. In the alcohol-pretreated rats, liver injuries were not demonstrated on the basis of the liver weight per body weight, the levels of serum alanine aminotransferase and hepatic microsomal glucose-6-phosphatase activities. By the CH treatment, alcohol-pretreated animals showed the significantly increased activity of hepatic microsomal CYPdAH. Concomitantly $V_{max}$ value in CYPdAH was more increased, whereas $K_{M}$ value more decreased in alcohol-pretreated animals by the treatment of CH. In conclusion, the increasing cause of microsomal CYPdAH in CH-treated rats pretreated with alcohol may be due to induction of enzyme protein in rat liver.r.r.

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.

TO evaluate an effect of cyclohexane treatment on the degree of liver damage, rats were induced liver damage with 10 or 17 times $CCl_4$ injection (0.1 m1/100 g body wt., 50% $CCl_4$ dis-solved in olive oil) at intervals of every other day. Cyclohexane (1.56 g/kg body wt., i.p.) was administrated to the animals at 48 hours after the last pretreatment of $CCl_4$ . Rats were sacrificed at 4 hours after injection of cyclohexane. On the basis of histopathological findings, liver weight/body weight (LW/ BW, %), activities of serum alanine aminotransferase (ALT), xanthine oxidase (XO) and akaline phosphatase (ALP), and contents of liver protein and manlondialdehyde (MDA), $CCl_4$ -pretreatment induced liver damage. And $CCl_4$ 17 times treated group showed more severe liver damage than $CCl_4$ 10 times treated group. Administration of one dose of cyclohexane to $CCl_4$ 10 times treated animals resulted in the enhanced liver damage; liver necrosis with proliferation of fibroblast and bile duct abnormality, and increase in hepatic MDA content and the activities of serum ALP and ALT, But the enhanced liver damage was not found in $CCl_4$ 17 times treated animals. Serum cyclohexanone concentrations at 4 or 8 hours after injection of cyclohexane were higher in all liver damaged groups than normal group and were somewhat higher In $CCl_4$ 17 times treated animals than $CCl_4$ 10 times treated ones. Among the oxygen free radical metabolizing enzymes, hepatic cytochrome P45O dependent aniline hydroxylase (CYPdAH) activity in cyclohexane metabolizing enzyme system was meaningfully increased by the injection of cyclohexane to the liver damaged rats, with increased Vmax and high affinity to aniline. LW/BW (%) and activities of serum XO and ALT were more significantly increased in liver damaged groups than normal group by administration of cyclohexanone. In conclusion, it is assumed that an enhancement of liver damage by injection of one dose of cyclohexane to liver damaged animals might be caused by oxygen free radicals and cyclohexanone.

To evaluate an effect of cyclohexanone (CHO) treatment on the serum levels of glutathione S-transferase (GST) activity in acute liver damaged animals, acute liver damage was induced in rats with pretreatment of 50% $CCl_4$ in olive oil (0.1 ml/100 g body wt) intraperitoneally 14 times every other day. To liver damaged rats, CHO (1.56 g/kg body wt, i. p.) was injected once and then rats were sacrificed at 4 hours after injection of CHO. Increasing rate of GST activity to the control in serum was higher in CHO-treated rats pretreated with CCL$_4$ than the $CCl_4$-pretreated those. All the more, the injection of CHO to the liver damaged rats led to more enhanced liver damage on the basis of liver functional findings, i. e., serum levels of alanine aminotransferase (ALT) activity, liver weight per body weight, and malondialdehyde content. The changing pattern of serum ALT activity was similar with that of GST activity, whereas that of liver in both enzymes differed more or less from each other; the liver GST activity in CHO-treated rats pretreated with $CCl_4$ being more increased tendency than that of $CCl_4$-pretreated rats. Concomitantly the injection of CHO showed a increasing tendency of liver GST activity compared with the control. Furthermore, CHO injection to the liver damaged rats showed somewhat higher Vmax in the kinetics of liver GST enzymes. In conclusion, injection of CHO to the liver damaged animals led to more increased activity of serum GST, and it may be chiefly caused by the alteration of membrane permeability.

In Nan-Gyung, showed that could know the lung condition taking pulse with the weight of three beans, the heart condition taking pulse with the weight of six beans, the spleen condition taking pulse with the weight of nine beans, the liver condition taking pulse with the weight of twelve beans, the kidney condition pressing to bone(骨). This theory is first suggested in Nan-Gyung(難經). In those case, the weight of three, six, nine, twelve beans and pressing to bone don't mean not the real weight but the relative weight(輕重) of taking pulse(按脈). In other words, those represent Boo Jung Chin(浮中沈), which are the conception of the upper, the meddle, the lower part(上中下). So, we could take pulse of the heart and the lung condition in Boo(浮), the spleen condition in Jung(中), and the liver and the kidney condition in Chim(沈). The heart and the lung pulse showed in the Boo(float level) must be seen with Boo-Mack(부맥 : float pulse), the liver and the kidney pulse showed in Chim (sinklevel) must be seen also with Chin-Mack(沈脈 : sink pulse). The result of the method of taking pulse of viscera with relative weight focused on the as pect of mornal pulse(平脈) and disease pulse(病脈) of five viscera in Mack-Gyung publeshed later than Nan-Gyung and special works which made a comprehensive survey the result is as follow. 1. In normal pulse of five viscera, the heart and the lunk pulse were shown with Boo-Mack(浮脈:float pulse) as the central figure, the liver's and the kidney's pulse were shown centering around Chim-Mack(沈脈: sink pulse) and the spleen's pulse was shown with Wan-Mack(緩脈) which is vital force of stomach(胃氣) and seen in only middle part. 2. In disease pulse of five viscera, frequently, the heart and the lung pulse was shown as Chim-Mack(sink pulse), the liver and the kidney pulse was seen as Boo-Mack (float pulse). 3. In the case of normal pulse. the method of taking pulse with relative weight in Nan-Gyung agree with the normal pulse of five viscera in Mack-Gyung. But in the case of disease pulse, they didn't correspond with the other. 4. So the method of taking pulse with relative weight in Nan-Gyung is not the exam pulse which ca be used in the clinical diagnosis but one of the feeling pulse way to bring in the conception of location of the visceras. 5. From now on, the method of taking pulse rdlated to relative weight need to be looked into minutely compared with later physician's theory than Mack-Gyung.

Severe protein-calorie malnutrition, common in patients with advanced liver disease, can seriously undermine the capacity for regeneration and functional restoration of liver. Nutritional supplementation for these patients can improve biochemical and hormonal abnormalities. However, these effects were not identified in patient with nonalcoholic liver cirrhosis. To determine effects of nutritional supplementation in patients with nonalcoholic liver cirrhosis, 77 subjects aged 29 to 69 years participated in this study for 12 weeks and were subdivided into three groups; normal diet group (Control group, n ＝ 16), branched-chain amino acid supplementation group (BCAA group, n ＝ 31), nutritional supplementation group (NS group, n ＝ 30). Anthropometric parameters, hemoglobin, hematocrit, blood cell counts, serum levels of lipids, vitamins, minerals and fatty acid composition, and plasma amino acids were examined. The mean values of age and height, and the initial values of weight and body mass index (BMI) were not different among all groups. After 12 weeks, there were no significant changes in these values in Control group. Only NS group showed significant increases in weight, lean body mass, midarm circumference, triceps skinfold thickness. Serum transferrins were increased both in BCAA and NS groups. Plasma levels of branched-chain amino acids, urea amino acids and glutamic acid were also significantly increased in these groups, but plasma levels of ammonia, serum LDL cholesterol and atherogenic index were decreased. However, there were no significant changes in serum levels of vitamin and mineral and composition of fatty acids in phospholipids in these groups. These results showed that the nutritional supplementation for patients with nonalcoholic liver cirrhosis can more improve nutritional status in these people together with increases of weight, body fat and lean body mass, compared to only BCAA supplementation. To ascertain and investigate the appropriate nutritional supplementation for patients with nonalcoholic liver cirrhosis, further studies are necessary.
