Pretreatment with Taraxacum Mongolicum H(TMH) prior to the administration of on $CCl_4$ significantly prevented the increased serum enzymatic activity of aminotransferase(ALT, AST), gamma-glutamyl transpeptidase(GGT) and bilirubin concentration in dose-dependent manner. In addition, pretreatment with TMH also significantly restored the elevation of hepatic malondialdehyde formation and the depletion of reduced glutathione content in the liver $CCl_4$-intoxicated rats. The restoration of microsomal aniline hydroxylase and aminopyrine N-demethylase activities indicated the improvement in functional status of endoplasmic reticulum. $CCl_4$-induced hepatotoxicity was also essentially prevented, as indicated by a liver histopathologic study. TMH showed antioxidant effects in $FeCl_2$-ascorbate-induced lipid peroxidation in rat liver homogenate and in superoxide radical scavenging activity. Our results suggest that the protective effect of TMH against $CCl_4$-induced hepatotoxicity possibly involve mechanisms related to its ability to block p450-mediated $CCl_4$ bioactivation and free radical scavenging effects.

Dystrophic calcinosis cutis associated with spontaneous hyperadrenocorticism was diagnosed in a 8-year-old female Chihuahua dog with erythematous, erosive, numerous papules, plaques, and crusts on the bilateral trunk, and inguinal region. Serum biochemical abnormalities included increases in alkaline phosphatase (ALP), alanine aminotransferase (ALT), gamma-glutamyl transpeptidase (GGT), and cholesterol. Radiographs showed mild hepatomegaly and subcutaneous lobulated calcific deposits. Histopathologic examination demonstrated diffuse deposition of basophilic calcified material in the dermis. Von Kossa's stain confirmed calcium deposition. Therapy with diltiazem was useful in resolving calcinosis.

Human milk and bovine milk in normal stage were fractionated four parts : whey, skimmilk membrane, and casein pellet. The specific activity (nmole / mim / mg protein) and distribution ratio(%) of suborganella marker enzymes in each separated milk fraction were determined. Especially, neutral $Ca^{2+}$-ATPase, acid $Ca^{2+}$-ATPase, NADH-cytochrome C reductase, and acid phosphatase were higher in human milk. However, both $Ca^{2+}$-ATPases were not detected in all fractions of bovine milk. On the other hand, 5'-nucleotidase, phosphodiesterase I, alkaline phosphatase, and $\gamma$-glutamyl transpeptidase activities in bovine milk were higher than in human milk. Most of the marker enzymes were highly distributed in cream fraction of either human milk or bovine milk, and their specific activities were high to 24 fold from 3 fold when compared with that of whole milk. These results suggest that marker enzymes in mammary epitherial cell are transfered into cream fraction by the membrane rearrangement, and different biochemical reaction between human and bovine exists for milk secretion in mammary gland.

Genetic associations have been quantified using a number of statistical measures. Entropy-based mutual information may be one of the more direct ways of estimating the association, in the sense that it does not depend on the parametrization. For this purpose, both the entropy and conditional entropy of the phenotype distribution should be obtained. Quantitative traits, however, do not usually allow an exact evaluation of entropy. The estimation of entropy needs a probability density function, which can be approximated by kernel density estimation. We have investigated the proper sequence of procedures for combining the kernel density estimation and entropy estimation with a probability density function in order to calculate mutual information. Genotypes and their interactions were constructed to set the conditions for conditional entropy. Extensive simulation data created using three types of generating functions were analyzed using two different kernels as well as two types of multifactor dimensionality reduction and another probability density approximation method called m-spacing. The statistical power in terms of correct detection rates was compared. Using kernels was found to be most useful when the trait distributions were more complex than simple normal or gamma distributions. A full-scale genomic dataset was explored to identify associations using the 2-h oral glucose tolerance test results and γ-glutamyl transpeptidase levels as phenotypes. Clearly distinguishable single-nucleotide polymorphisms (SNPs) and interacting SNP pairs associated with these phenotypes were found and listed with empirical p-values.

The objective of this study was to understand changes of plasma metabolites, hormones, and mRNA level of cytoplasmic phosphoenolpyruvate carboxykinase (PEPCK-C) in liver in spontaneous clinical ketosis; 10 clinically ketotic cows and 10 healthy cows were chosen from the same dairy farm. Eleven blood parameters and liver fat content were measured in all cows, and mRNA levels of PEPCK-C in liver were measured by semi-quantitative reverse transcription (RT) polymerase chain reaction (PCR). In ketotic cows, concentration of plasma glucose decreased (p<0.01), concentration of plasma nonesterified fatty acids (NEFA) and $\beta$-hydroxybutyric acid (BHBA) increased (p<0.01), liver fat content (18.8% wet weight) and activity of plasma aspartate aminotransferase (AST) increased (p<0.01), but concentration of plasma total bilirubin (TBIL), $\gamma$-glutamyl transpeptidase ($\gamma$-GT), and cholinesterase (CHE) increased (p>0.05). In addition, concentration of plasma insulin decreased (p<0.05), concentration of plasma glucagons decreased (p>0.05), and mRNA level of PEPCK-C in liver increased (p<0.05). It is concluded that the adaptative changes of metabolites, hormones, and mRNA level of PEPCK-C in ketotic cows were in favor of the enhancement of gluconeogenesis, the decrease of fat mobilization and the relief of ketosis, but these were still inadequate to relieve ketosis.

This study was performed to investigate the effect of chongkukjang intake on lipid metabolism and liver function in ethanol consumed rats. Twenty one Sprague-Dawley male rats aging 4 weeks old were used as experimental animals, which were divided into three dietary groups; casein diet(CA), soybean diet(SB) and chongkukjang diet(CJ). Alcohol was consumed with water as 25%(v/v) ethanol solution. After 4 weeks of experimental period, rats were sacrificed to get blood and liver samples for analysis of lipids, lipid peroxides, antioxidative enzymes and biochemical indices of liver function. The mean body weight, food intake and liver index were not significantly different among three groups. Serum level of total lipid, triglyceride and total cholesterol of chongkukjang diet group was the lowest among three groups although the difference was not significant. HDL-cholesterol level was significantly(p<0.05) higher in chongkukjang diet group than that of casein diet group. LDL-cholesterol level of chongkukjang and soybean diet group was significantly(p<0.05) lower than that of casein diet group respectively. Liver TBARS of chongkukjang and soybean diet group was significantly(p<0.05) lower than that of casein diet group respectively. The superoxide dismutase activity of chongkukjang diet group was significantly(p<0.05) higher than that of casein diet group. Catalase activity was not significantly different among three groups. As indices of liver function, glutamic oxaloacetic transminase(GOT), glutamic pyruvic transminase(GPT), $\gamma$-glutamyl transpeptidase($\gamma$-GTP) and lactate dehydrogenase(LDH) were not significantly different among three groups. Serum alcohol concentration and activities of alcohol dehydrogenase(ADH) and aldehyde dehydrogenase(ALDH) were not significantly different among three groups. The chongkukjang diet seems to give a beneficial effect for improving lipid metabolism by increasing HDL-cholesterol level and SOD activity while reducing liver TBARS level. However, effect on liver function has to be investigated further.

1. Objects: This case study reports a liver injury in treatment of constipation with Yeoldahanso-tang plus Rheum rhabarbarum. 2. Methods: The patient's subjective symptoms and the laboratory data including aspartate transaminase(AST), alanine transaminase(ALT), alkaline phosphatase(ALP), and gamma($\gamma$)-glutamyl transpeptidase(GGT) were observed before and after liver injury. We used the Roussel Uclaf Causality Assessment Method(RUCAM) scale in order to find out whether if Yeoldahanso-tang plus Rheum rhabarbarum was related with the liver injury. 3. Results: The patient's AST and ALT were elevated more than twice after a 3week administration period of herbal medicine. After discontinuation of the herbal medicine and administration of hepatic protective medication, AST and ALT decreased. The patient's general condition improved during hospitalization. The RUCAM score was estimated at 8. 4. Conclusions: This case is presented to bring more attention to the toxicity of herbal medicine.

Objectives : This study was carried out to investigate the hepatoprotective effects of mixture with Hovenia dulcis Thunb (HDT) and Acer tegmentosum Maxim(ATM) on D-galactosamine-induced liver failure in rats. Methods : The animals were divided into 4 groups: control, with liver failure and no treatment; H1A1, with liver failure and oral treatment with HDT 1 and ATM 1; H1A2, with liver failure and oral treatment with HDT 1 and ATM 2; H1A4, with liver failure and oral treatment with HDT 1 and ATM 4. The animals were treated for 3 weeks and then examinations of change of body weight, aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma glutamyl transpeptidase ($\gamma$-GTP), total cholesterol, triglyceride, total bilirubin, superoxide dismutase (SOD), catalase, histopathologic change, and complete blood count (CBC) were performed. Results : All experimental groups had significantly decreased AST in serum and markedly increased activity of SOD as compared with the control group. H1A1, and H1A4 significantly decreased ALT in serum and H1A4 at 2 weeks was significantly higher on the change of body weight as compared with the control group. In histopathologic change of liver tissue by light microscopy, all experimental groups showed recovery effects of liver cells which were damaged by D-galactosamine. Conclusions : Based upon these results, it could be assumed that a mixture of HDT and ATM has hepatoprotective and antioxidative effects on D-galactosamine-induced liver failure. Therefore, a mixture of HDT and ATM might be utilized as a protective agent in therapy for liver diseases.
