The effect of treatment with pine needle oil upon rat hepatocytes exposed to alcohol was investigated. The body weight gain, ratio of liver and kidney to body weight, and serum biochemistry of rats administered both alcohol and pine needle oil were compared to control rats treated with alcohol alone. Normal untreated control rats, negative control rats with ethanol treatment, positive control rats with both alcohol and the commercially available hangover cure solution (HCS) treatment and the test group with both alcohol and pine needle oil treatment exhibited aspartate aminotransferase (AST) levels of $84.43{\pm}47.88\;U/L$, $254.57{\pm}463.20\;U/L$, $70.29{\pm}12.60\;U/L$ and $67.00{\pm}5.06\;U/L$, respectively, and cholesterol levels of $95.71{\pm}6.86\;mg/dl$, $113.80{\pm}38.19\;mg/dl$, $91.57{\pm}6.30\;mg/dl$ and $82.29{\pm}4.98\;mg/dl$, respectively. Alanine aminotransferase (ALT) levels were $44.00{\pm}9.04\;U/L$ in normal untreated control rats, increased to $215.43{\pm}428.93\;U/L$ with the administration of ethanol, but interestingly were significantly reduced to $37.83{\pm}6.57\;U/L$ in the test group (p<0.05). Triglyceride (TG) levels were $39.57{\pm}8.62\;mg/dl$ in normal untreated rats, increased to $73.71{\pm}61.20\;mg/dl$ in rats administered alcohol, but were reduced to $26.14{\pm}4.82\;mg/dl$ in the test group (p<0.0l). The pine needle oil treatment significantly reduced the levels of AST, ALT and TG compared to the control rats. These results indicate that pine needle oil can positively mediate the effects of alcohol on hepatocytes and general liver functions.

This study was conducted to investigate the effect of fermented blackberry drinks (BD) on carbon tetrachloride ($CCl_4$)-induced liver injury in rats. Male Sprague-Dawley rats were randomly divided into four groups with 6 rats per group: control, $CCl_4$, $CCl_4$ plus BD $3ml\;kg^{-1}$, and $CCl_4$ plus BD $6ml\;kg^{-1}$. We found that the levels of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were significantly increased and the activity of antioxidant enzyme glutathione peroxidase (GPx) in the liver was decreased in rats treated with $CCl_4$ alone when compared with the control group. However, the administration of BD attenuated the levels of serum AST and ALT in $CCl_4$-treated rats. Moreover, the administration of BD significantly increased the activity of GPx in $CCl_4$-treated rat livers. Taken together, these results suggest that BD could protect the liver from $CCl_4$-induced hepatic damage.

Objectives: Oxidative stress plays a central role in diabetes-induced complications. In the present study, the protevtive effect of Artemisia turanica (A. turanica) was evaluated against diabetes-induced liver oxidative stress and dysfunction. Methods: Fifty male Wistar rats were randomly divided into five groups: control, diabetic, diabetic + metformin, diabetic + A. turanica extract, and diabetic + A. turanica extract + metformin. Experimental diabetes was induced by a single-dose (55 mg/kg, intraperitoneally (ip)) injection of streptozotocin (STZ). Metformin (300 mg/kg) and A. turanica extract (70 mg/kg) were orally administrated three days after STZ injection for four weeks. The levels of malondialdehyde (MDA), total thiol content and superoxide dismutase (SOD) and catalase activities were measured in the liver tissue. Serum glucose concentration, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities were also determined. Results: In the diabetic group, serum glucose concentration, serum AST and ALT activities and liver MDA level were significantly higher while tissue total thiol content as well as catalase and SOD activities were lower, compared to the control group. Serum glucose in diabetic rats treated with metformin + A. turanica extract showed a significant decrease compared with the diabetic group. In all the A. turanica extract and metformin treated groups, serum ALT, tissue MDA level, total thiol content and SOD activity significantly improved compared with the diabetic rats. However, treatment of the diabetic rats only with metformin could not significantly change the activities of catalase and AST compared with the diabetic group. Conclusion: These findings suggested that A. turanica extract had a therapeutic effect on liver dysfuncyion and oxidative stress induced by diabetes, that may be probably due to its antioxidant and antiinflammatory effects.

This paper was intented to charily the cause of an increase of serum guanase activity in rats following injection of $CCI_4$. The cause of increasing serum guanase was focused on the change of guanase activities in both serum and liver, and additionally, these results were compared with the previously known alanine aminotransferase (ALT). Concomitantly the microscopic investigation on the histologic changes, and the determination of lipid peroxides of liver were combined in this experiment for a correlation to observe that the activity of guanase would be effected by the various degree of hepatic injury induced by $CCI_4$. The serum levels of guanase were increased about 2 fold in the fatty change stage (3-12 days), 5.2 fold representing the peak value in necrosis stage (21days), 4.5 fold in early cirrhosis stage (48 days), and 2 fold in severe cirrhosis stage (92 days). These changes of serum guanase activity showed similar patterns to those of ALT activity and lipid peroxides in liver cell. The changes of liver guanase activities showed an increase, whereas ALT activities in liver were markedly decreased. It is likely that the increase of serum guanase activity is based on the excess leaking of guanase into blood by the result of accelerated enzyme synthesis in liver cell of $CCI_4$ intoxicated rats. In addition, the possibility could not be ruled out, however, that the increase of serum guanase activity would be caused by the alteration of membrane permeability.

The author investigated the zinc concentrations in sera of 110 methamphetaimine abusers (male 87, female 23) and of 41 healthy official workers(male 29, female 12) using inductively coupled plasma emission spectrometer. The serum zinc concentrations were analysed according to hepatitis C virus antibody(Anti HCV), hepatitis B surface antigen(HBsAg) and alanine aminotransferase(ALT) value in both groups. The analytical results were obtained as follows 1. The mean zinc concentration of MAP abuser group($298.5{\pm]246.9{\mu}g/100ml$) was 2.5 times higher than that of control group($118.8{\pm}25.4{\mu}g/100ml$). 2. The distributions of zinc concentration in both groups were skewed pattern. 3. The zinc concentrations were higher in Anti HCV-positive group and abnormal ALT value group than Anti HCV-negative group and normal ALT value group. But HBs-Ag positive group had lower zinc concentration than HBs-Ag negative group. 4. The number of anti HCV-positive subjects was increased and the zinc concentrations were decreasd in proportion to the abusing duration of MAP.

Objectives : Effects of Rhizoma Alismatis extract on lipid composition and TBARS (thiobarbituric acid reactive substances) formation were investigated in rat fed high fat diet. Methods : Seventy male Sprague-Dawley rats were used in these experiments and housed with food and water ad libitum and Twenty rats were selected healthy over 400g body weight and fed high fat diet for 8 weeks. Rhizoma Alismatis extract was administerd at dose 100mg/kg/day, 200mg/kg/day and 300mg/kg/day p.o. for 4 weeks. Then Triglyceride, Total cholesterol, HDL-cholesterol, LDL-cholesterol, TBARS concentration and ALT(Alanine Aminotransferase), AST(aspatate transaminase) activities were determined. Results : Plasma total LDL-cholesterol showed a tendancy to decrease in all treated group(P<0.05), however plasma HDL-cholesterol, total cholesterol, triglyceride showed no significantly different. Rhizoma Alismatis extract feedings resulted in a decrease in plasma TBARS(p<0.05) concentration and AST, ALT activites but contents of TBARS in liver showed no significantly different among all the treatments. Conclusions : Reviewing these experimental results, it appears that Rhizoma Alismatis extract was effective for inhibiting lipid peroxidation and decreasing LDL-cholesterol concentration.

Protective effects of various natural flavonoids on carbon tetrachloride $(CCl_4)-induced$ hepatotoxicity were investigated in primary cultured rat hepatocytes. Some of these flavonoids decreased the ALT and LDH releases induced by $CCl_4$ in A dose-dependent manner. Neohesperidin, hesperetin, baicalin, baicalein and quercetin inhibited $CCl_4-induced$ alanine aminotransferase (ALT) release. In addition, quercetin, quercitrin, neohesperidin, baicalin, baicalein and naringin reduced $CCl_4$ induced lactate dehydrogenase (LDH) leakage. Among these flavonoids, quercitrin, quercetin, baicalin and baicalein possessed potent protective effects and were selected for the further investigation on lipid peroxidation. These four flavonoids inhibited dose dependently $CCl_4-induced$ lipid peroxidation. Especially, the protective effects of quercetin and baicalein were similar to silybin as a well-known hepatoprotective agent. These results suggest that these four flavonoids have significant cytoprotective effects and possibility of therapeutic effect on chemical-induced liver diseases.
