Effects of hesperetin and naringenin on the concentration of triacylglycerol in the serum and liver were studied in male golden hamster fed with the semipurified diet containing at 1% level of them for 3 weeks. The concentration of triacylglycerol in serum of the naringenin group decreased by 31%, whereas that in liver increased by 37% compared to the control group. The concentration of triacylglycerol in the serum and liver of the hesperetin group was slightly lower than the control group. The activity of microsomal phosphatidate phosphohydrolase in the liver, which is a key enzyme for biosynthesis of triacylglycerol, was significantly inhibited in the hesperetin group, whereas it was not affected in the naringenin group. The effect of hesperetin on phosphatidate phosphohydrolase was also measured in vitro. Hesperetin decreased the activity of phosphatidate phosphohydrolase with a dose-dependent manner. Both naringenin and hesperetin did not statistically affect the daily food consumption, body weight, liver weight, and total cholesterol in the serum. The observation accounts for the hypotriglyceridemic effect of hesperetin in the hyperlipidemic hamster.

Effects of powdered siho(bupleuri radix) on serum and liver lipid composition and antioxidative capacity were investigated in rat fed high oxidized fat. Sixty male Sprague-Dawley rats weighing 161.25$\pm$2.51g were blocked into four groups according to body weight and raised seven weeks with basal diet(normal group), basal diet and 10% oxidized fat(control group), basal diet, 10% oxidized fat and 2% powdered siho(2% powdered siho group) and basal diet, 10% oxidized fat and 3% powdered siho(3% powdered siho group). Feed intake, body weight gain and feed efficiency were not significantly different among oxidized fat diet groups. The values of total cholesterol and triglyceride in plasma and liver showed no significantly different(p>0.05) in the oxidized fat diet groups. Plasma HDL-cholesterol showed atendency to increase in powdered siho diet groups. The values of thiobarbituric acid in plasma and liver were lower in the powdered siho diet groups than control group. Plasma GOT and GPT activity showed a tendence to decrease in powdered siho groups. Liver glutathione peroxidase activity showed a tendence to increase in powdered siho diet groups. Thus, it seems that powdered siho had some antioxidative elements.

To evaluate an effect of liver xanthine oxidase on the induction of liver damage, carbon tetrachloride (CCl4) was intraperitoneally injected twice at 0.1ml/100g body weight to the rate fed a low (LP)or high protein diet(HP) while the control group fed LP or HP received only olive oil. The changing rate of liver xanthine oxidas activity was compared with that of a free radical generating enzyme, liver aniline hydroxylase and a scavenging enzyme, glutathions S-transferase activity between the rate fed a LP and those fed HP, and the two groups treated with CCl4. Concomitantly, the degree of liver damage which could be considered as the paramete for CCl4 metabolism in case of CCl4-intoxicated animal was observed in the present experimental conditions and the effect of allopurinol, xanthine oxidase inhibitor, on the CCl4-toxicity of rate liver was alos demostrated. On the other hand, the comparative effect of actinomycin D on the liver and serum xanthine oxidase of CCl4-treated rats fed HP with that of those fed LP and the kinetics of purifed liver enzyme from the liver of CCl4-treated rats fed HP was also compared with that of those fed LP to clarify the differences of xanthine oxidase activity between two groups. The increasing rate of liver weigth/body wt, serum levels of ALT and the decreasing rate of hepatic ALT activity and protein contents to each control group were higher in CCl4-treated rats fed HP than those fed LP. Under the animal models as indentified by the present data herein, the liver xanthine oxidase activity was higher in CCl4-treated rats fed HP than those fed LP, and the control group fed HP also showed the much higher activity xanthine oxidase than that fed LP, whereas there were no differences in the activity of hepatic aniline hydroxylase and glutathions S-transferase between the two group treated with CCl4. Although the hepatic aniline hydroxylase activity was somewhat higher in the rats fed HP than those fed LP, the increasing rate of liver xanthine oxidase to the rats fed LP was higher in those fed HP than that of liver aniline hydroxylase. The degree of liver damage identified such as liver weight and serum ALT activity was less in the CCl4-treated rats pretreated with allopurinol. These results suggest that even a system at which xanthine oxidase acts as well as the drug metabolizing enzyme may influence the acelatin of CCl4 metabolism. In addition, the purified liver xanthine oxidase from CCl4-treated rats fed HP showed decreased Km value when compared to its control group. The Km value of liver xanthine oxidase of CCl4-treated rats fed LP showed a similar Km value with its control group. Furthermore, the decreasing rate of liver and serum xanthine oxidase acitivity in CCl4-treated rats pretreated with actinomycin D to the CCl4-treated rats was higher in rats fed HP than in those fed LP. These results suggest that the inductino of xanthine oxidase in CCl4-treated rats fed HP may be greater than in those fed LP.

This was conducted to determine the effects of body weight, organ weight, hematological values and biochemical parameters by L-carnitine in the ovariectomized (OVX) rats. The animals were divided into 4 groups. Intact group (n=10) received no treatment and operation. Sham group (n=10) received only sham operation and no treatment. OVX group (n=10) received operation and no treatment. OVX+Carn group (n=10) received operation and L-carnitine. Body weight was significantly lower in OVX+Carn group than in all other groups. Also, organ weight such as heart, liver, spleen and kidney was measured. The heart and spleen weight were significantly lower in the OVX+Carn group than in the Intact and Sham group. The liver weight in the OVX+Carn group was significantly differences in comparison with those in the other groups. Also, there was significantly differences in the organ weight of kidney between in the OVX+Carn group and in the other groups. The hematological values of WBC, RBC, MCV, MCH and MCHC were no significant differences in any other groups. The total cholesterol, triglyceride and high density lipoprotein decreased significantly in the OVX+Carn group as compared to those in the OVX group. But, there were no significant differences in low density lipoprotein in any other groups. We conclude that L-carnitine enhanced the body weight in the ovariectomized rats. Our findings suggest that L-carnitine may influence the process of absorption of fat in the ovariectomized rats.

Objectives This study was performed to evaluate anti-obesity effects of Crataegus pinnatifida (CP) on high-fat-diet induced obese mice. Methods The experimental animals were divided into four groups: normal diet (NOR) group, high fat diet (HFD) group, HFD+Xenical (XEN) group, and HFD+CP (CP) group. NOR group was fed a normal diet and the other three groups were fed high fat diet during the experiment. After the first two weeks of diet, XEN group and CP group were administered with XEN or CP for seven weeks, respectively. After that, we measured body weight, liver weight, fat weight, food intake, and serum concentrations of lipids and liver enzymes. Also the liver, intestine, fat tissue was removed to estimate the obesity-related mRNA expressions and the stool sample was collected to analyze the gut microbiota. Results We found that body weight, fat weight, and triglyceride level were decreased significantly in CP group compared to HFD group. Also CP significantly suppressed gene expressions associated with lipogenesis and inflammation, and increased gene expressions of browning of white adipose tissue and mitochondrial biogenesis. Moreover, it shifted the microbial diversity closer to that of NOR group and increased Firmicutes/Bacteriodetes ratio. Conclusions These results suggest that CP decrease body weight, fat weight and serum triglyceride. Also it inhibit inflammation and adipogenesis, altering gut microbial diversity and abundance. In conclusion, CP could be used as a therapeutic drug for obesity via gut microbiota modulation.

To assess the clinical and nutritional status of long-term survivors of biliary atresia, history taking, medical record review, physical examination (height, weight, MAC, TSF), blood tests (LFT, prothrombin time, platelet count, prealbumin, calcium) and liver needle biopsy were performed in 12 patients in whom Kasai procedure were performed more than 10 years ago at Department of Pediatric Surgery in Seoul National University Hospital. None were below the 5th percentile in height and weight. TSF was above the 75th percentile in all patients and showed good subcutaneous fat deposition. MAC was above the 5th percentile in all patients. Serum prealbumin level was abnormal in 2 patients with abnormal liver function and revealed visceral protein malnutrition. Serum calcium level was decreased below normal range in 4 patients with abnormal liver function. One patient had mild ascites. Five patients had abnormal liver function and 7 patients showed clinical manifestation of portal hypertension. Liver needle biopsy was performed in 5 patients and no cirrhotic change was observed. Although some patients who have survived for more than 10 years after Kasai procedure developed protein malnutrition and vitamin deficiencies, growth and development and nutritional status were generally satisfactory. Five patients(42%) showed normal liver function and no portal hypertension. In conclusion, Kasai procedure is satisfactory as a primary treatment in biliary atresia but significant portion of long-term survivors had abnormal liver function and portal hypertension. Continuous and careful follow-up is necessary to determine when liver transplantation may be indicated.

This study was conducted to investigate the reference value of mercury (Hg) in liver and kidney of Korean population. The mercury concentration in 244‘sudden and unexpected death’autopsies (male: 180, female: 64) aged from 0 to 87 years was analyzed. The concentration of mercury was measured by atomic absorption spectrophotometer (Perkin-Elmer Model 5100) with mercury/hydride generating system (FIAS 400). The contents of mercury in liver and kidney fitted well the log-normal distribution rather than normal distribution. Geometric mean concentration of mercury in liver and kidney was 0.115 $\mu\textrm{g}$/g wet weight and 0.149 $\mu\textrm{g}$/g wet weight, respectively. Geometric mean concentration of mercury in female was higher than in male (p < 0.01). The mercury content in liver and kidney increased with age up to the forties and slightly decreased there-after. The regression model of mercury deposit in liver and kidney by age was predicted as the following equation : Log LHg : -1.0576＋0.0045$.$Age-0.0001$.$Age$^2$＋0.0873$.$Sex, Log KHg = -1.0576＋0.0152$.$Age-0.0002$.$Age$^2$＋0.1935$.$Sex. The liver burden of mercury was estimated to be 158.3∼161.3 $\mu\textrm{g}$ in male and 163.0∼166.9 $\mu\textrm{g}$ in female. The kidney burden of mercury was estimated to be 42.0∼42.9 $\mu\textrm{g}$ in male and 55.5∼57.1 $\mu\textrm{g}$ in female.
