The protective effect of Carthamus tinctorius L. Semen on the carbon tetrachloride induced liver damaged rats were studied. First, methanol extract was prepared and the extract was fractionated with hexane, $CHCl_3$, BuOH and $H_2O$ respectively. Animals were divided into 6 groups and each group was treated with each fraction respectively. To investigate the hepato-protective effect of Carthamus tinctorius L. Semen AST, ALT, albumin, TP, cholesterol, TG, creatinine and total bilirubin values were measured in each treated group and compared with those of control group. GST activity was increased in BuOH group compared with the control group. In malondialdehyde levels, all fractions was decreased compared with the control group. In histopathologic examination, hexane and $H_2O$ fractions of Carthamus tinctorius L. Semen observed mild degree of ballooning degeneration. The results show the protective effect of Hexane,$CHCl_3$, BuOH and $H_2O$ fractions on hepatotoxicity of $CHl_4$ by decreasing ALT, AST, bilirubin, cholesterol, TG and BUN. It seems that the decrease of MDA are related to the recovery effect. The protective effects of Carthamus tinctorius L. Semen fractions in hepatotoxic pathogenesis by $CHl_4$ was suggested in blood chemistry analysis and histopathologic examination.

The studies were attempted to investigate the therapeutic effect of Solanum lyratum extract(SLE) on the liver damage induced by carbon tetrachloride in rats. Male rats (Sprangue-Dawley) were treated with subchronic concentration of $CCl_4$, which was 1 mg/kg of $CCl_4$ via per oral administration daily for three days. The level of serum cholesterol, transaminase, bilirubin and BSP were measured. Treatment of SLE significantly decreased the increment in serum transaminase activities, total cholesterol and enlargement of liver but serum bilirubin was not reduced. The protective effect was observed when SLE was given daily for 4 weeks after $CCl_4$ treated for 3 days. SLE administration to rats prevented the development of fatty change, necrosis, and fibrosis induced by $CCl_4$. The results suggest that SLE has appreciable therapeutic effect on $CCl_4$ induced hepatotoxicity.

In the present study, Thespesia populnea (Malvaceae) bark was extracted with methanol and water. The extracts were vacuum dried to yield the respective methanol (MET) and aqueous extract (AET). The extracts were evaluated for hepatoprotective activity against carbon tetrachloride $(CCl_{4})$ induced liver damage at 2 dose levels (250 and 500 mg/kg). The biochemical parameters observed in serum were total bilirubin, alkaline phosphatase (ALP), serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT) levels and total protein. Aspartate transaminase (AST), alanine transaminase (ALT) and total protein levels in liver were also evaluated. Histopathological study on the liver tissue was also performed. The extracts exhibited dose dependent reduction in total bilirubin, ALP SGOT, SGPT, AST, ALT and increase in total protein (serum and liver) levels. The extracts also exhibited only mild hepatocytic damage compared to the $CCl_{4}$ Treated group. MET was found to exhibit higher hepatoprotection than AET.

1, 1-dichloroethylene (DCE) is well known hepatotoxicant as a model acute hepatotoxicity and selectively injure the bile canalicular membrane of centrilobular hepatocytes. In this study, we investigated hepatic gene expression and histopathological changes in response to DCE treatment. DCE was administered once daily at 20 mg/kg up to 14 days via intraperitoneal injection. Five mice were used in each test group and were sacrificed at 1, 7, and 14 days. Serum biochemical and histopathological analysis were performed for evaluation of hepatotoxicity level. Direct bilirubin and total bilirubin activities were slightly elevated in treated group at 7 days. DCE treatment for 7 days resulted in centrilobular hepatocyte hypertrophy and hepatocyte vacuolation, and mild hepatocyte vacuolation and high hepatocyte basophilia were observed in 14 days treated group. One hundred twenty three up-regulated genes and 445 down-regulated genes with over 2-fold changes between treated and control group at each time point were used for pathway analysis. These data may contribute in understanding the molecular mechanism DCE-induced hepatotoxicity.

Hepatic cirrhosis is a common response to chronic liver injury from many causes and is one of the most common cause of all deaths. This study was carried out to compare experimental hepatic cirrhosis in rats to understand this disease and to apply for the pharmacokinetics in disease state. Following three kinds of experimental models were induced; 1) Bile duct ligation/scission (BDL/S), 2) N, N-dimethylnitrosamine(DMN), 3) Carbon tetrachloride. The hepatic cirrhosis was characterized by examing the liver/body weight ratio, serum biochemical values, hydroxyproline content in liver and histopathological lesions in cirrhotic rat liver. The results are as follows : (1) In BDL/S, the liver was enlarged to 250% of normal liver. In contrast the liver was shrinked to 48% and 78% of the normal liver in DMN and carbon tetrachloride, respectively. (2) In carbon tetrachloride and BDL/S, the serum ALT, AST, ALP and total bilirubin levels were significantly increased to 200~300% of normal level, while ALT and total bilirubin levels were significantly increased in DMN group. (3) Hydroxyproline content in cirrhotic rat liver was significantly 200~500% higher than that of normal liver. (4) Nodular formation with fibrosis was observed in BDL/S, DMN, carbon tetrachloride induced cirrhotic rat liver.

We executed this experiment to observe side effects of warfarin, the anticoagulant that is used for preventing thrombus in cardiovascular surgery for calves. The 6 calves(70-130 kg) were used in this experiment regardless of sexes. We administered warfarin at 0.07 mg/kg daily for 25 days. Blood was collected before warfarin administration, every five days for 30 days. PCV, RBC, WBC, fibrinogen, total protein and platelet as blood test, prothrombin time (PT) as blood coagulation test, and AST, SDH, total bilirubin, BUN and creatinine as serum biochemical tests were measured. As the result of the experiment, PT has been gradually increased after warfarin administration. It has been gradually increased and remains within the therapeutic range from the third day to the 28th day. PCV and RBC were decreased significantly from the value before the administration (p < 0.05). In the serum biochemical test, SDH shows significant increase comparing the value before the administration (p < 0.05). AST and total bilirubin were increased gradually from the value before the administration. Considering the result of the experiment, to give wafarin to prevent thrombus in cardiovascular surgery, we can get anticoagulation effect with minimal administration(0.07 mg/kg, PO) from the third day of the administration. However because of the decreased PCV and RBC, it may cause anemia. It may cause damage to liver based on the result of serum biochemical test.

Purpose: The purpose of the study is to investigate the relationship between total serum bilirubin(TSB) and transcutaneous bilirubinometry(TcB) in neonates with jaundice. Method: TcB from various sites(forehead, sternum, abdomen, buttock, hand, dorsalis-pedia) was measured using a JM-102 in a total of 102 neonate, 42 female and 60 male, with the mean 37.5 gestational week and the mean 2,903 gram of birth weight, as well as TSB from capillary punctures. Result: The mean bilirubin was 11.73 in serum, 20.55 on the forehead, 17.23 on the sternum, 16.19 on the abdomen, 18.22 on the buttock, 15.83 on the hand and 15.49 on the dorsalis-pedia. The relationship between TSB and TcBs were formulated by simple regression with 0.406 < r < 0.668(p < .000). A higher relationship was revealed between TSB and TCB at the forehead in infants of full-term, ABO incompatibility, and Hb greater than 16 mg/dl(r =0.725, 0.790, and 0.717, retrospectively). Phototherapy altered the measurement of TcB per site. Conclusion: TcB on the forehead is a reliable, noninvasive and convenient measurement of TSB in normal infants(Institutions need to establish quantitative equations representing the specific relationship between TSB and TCB according to the hemodynamic problems of infants such as ABO incompatibility, or low Hb).
