  • This study was carried out to investigate the liver protective effects of extracts from Persicae Semen (WT-003, WT-005, WT-006). The acute hepatic injury was induced by intraperitoneal injection of alpha-naphtylisothiocyanate (75 mg/kg, p.o.) and treated with WT-006 (100 mg/kg/day, 200 mg/kg/day, 400 mg/kg/day). The experimental hepatic fibrosis was induced by bile duct ligation/scission(BDL/S), duration of 4 weeks and treated with WT-003, WT-005 or WT-006 (200 mg/kg/days for 4 week). In acute liver injury, WT-006 (200 or 400 mg/kg) lowered serum alanine transferase(ALT) and aspartate transferase(AST) significantly. In fibrotic rats, WT-006 treatment inhibited the hydroxyproline deposition in liver and lowered serum AST, ALT and ALP, significantly. These results suggest WT-006 extract, which does not contain amygdalin, from Persicae Semen have liver protective and antifibrotic effects in rats.

  • This study investigated the physiological effects of a diet containing calcium oxide (CaO) on the olive flounder, Paralichthys olivaceus. The results indicate that the amount of calcium in the blood was higher in the calcium group compared with the controls. The aspartate amino transferase (AST) and alanine amino transferase (ALT) levels were lower in the calcium group, while lysozyme activity was higher in the calcium group. Histologically, fish in the calcium group had more hepatocytes in the liver and more intact scales. In addition, an attack experiment using Vibrio anguillarum (KCTC-2711) and Edwardsiella tarda (KCTC-3657) showed that the survival was higher in the calcium group compared with the controls. These results suggest that feeding fish CaO when they require it, such as during periods of gonadal maturation and rapid growth, will increase their immunity and resistance to pathogens.

  • The laying performance of Japanese quails fed graded levels of high glucosinolate ($92.5{\mu}mole/g$) rapeseed meal (RSM) was assessed. One hundred and twenty Japanese quails aged 1 day-old were assigned at random to four dietary treatments consisting of 0, 50, 75 or 100 g/kg RSM in the diet replacing part of the soybean meal and de-oiled rice bran in a standard quail ration. 12 female representative quails from each diet were selected at random and housed in individual cages from 7-20 wk of age. The egg production, feed intake and FCR was comparable among the different dietary groups. The egg quality characteristics, organoleptic evaluation of boiled eggs as well as the haematological (haemoglobin, total erythrocyte count, total leucocyte count) and biochemical (glucose, protein, cholesterol, aspartate amino transferase, alanine amino transferase and alkaline phosphatase) constituents did not differ significantly among the groups. The gross and histopathological studies of vital organs did not reveal any appreciable changes. The feed cost was reduced by the incorporation of RSM in the diet, but only the production cost of quails fed the 75 g/kg RSM was lower in comparison to other groups. In the present study, the laying potential of Japanese quail was well-maintained up to the 100g/kg dietary level of rapeseed meal.

  • The present study was designed to estimate the protective effect of (-) epigallocatechin gallate (EGCG) on ethanol-induced liver injury in rats. Chronic ethanol administration (6 g/kg/day ${\times}$ 60 days) caused liver damage that was manifested by the elevation of markers of liver dysfunction - aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, lactate dehydrogenase, bilirubin and ${\gamma}$-glutamyl transferase in plasma and reduction in liver glycogen. The activities of alcohol metabolizing enzymes such as alcohol dehydrogenase and aldehyde dehydrogenase were found to be altered in alcohol-treated group. Ethanol administration resulted in the induction of cytochrome p450 and cytochrome-$b_{5}$ activities and reduction of cytochrome-c reductase and glutathione-S-transferase, a phase II drug metabolizing enzyme. Further, ethanol reduced the viability of isolated hepatocytes (ex vivo) as assessed by trypan blue exclusion test and induced hepatocyte apoptosis as assessed by propidium iodide staining. Treatment of alcoholic rats with EGCG restored the levels of markers of liver injury and mitigated the alterations in alcohol metabolizing and drug metabolizing enzymes and cyt-c-reductase. Increased hepatocyte viability and reduced apoptotic nuclei were observed in alcohol + EGCG-treated rats. These findings suggest that EGCG acts as a hepatoprotective agent against alcoholic liver injury.

  • The hepatoprotective activity of lactic acid bacteria (Lactobacillus brevis HY7401, Lactobacillus acidophilus CSG and Bifidobacterium longum HY8001), which inhibited $\beta$-glucuronidase productivity of intestinal microflora, on t-BHP- or CCl$_4$-induced hepatotoxicity of mice were evaluated. These oral administration of lactic acid bacteria lowered $\beta$-glucuronidase production of intestinal microflora as well as Escherichia coli HGU-3. When lactic acid bacteria at a dose of 0.5 or 2 g (wet weight)/kg was orally administered on CCl$_4$-induced liver injury in mice, these bacteria significantly inhibited the increase of plasma alanine transferase and aspartate transferase activities by $17-57\%$ and $57-66\%$ of the $CCI_4$ control group, respectively. These lactic acid bacteria also showed the potent hepatoprotective effect against t-BHP-induced liver injury in mice. The inhibitory effects of these lactic acid bacteria were more potent than that of dimethyl diphenyl bicarboxylate (DDB), which have been used as a commercial hepatoprotective agent. Among these lactic acid bacteria, L. acidophilus CSG exhibited the most potent hepatoprotective effect. Based on these findings, we insist that an inhibitor of $\beta$-glucuronidase production in intestine, such as lactic acid bacteria, may be hepatoprotective.

  • The purpose of the present study was to investigate changes in hematological and serum biochemical parameters in ponies exercising 3 times a day. The study included 10 healthy 4- to 5-year-old Jeju crossbred ponies used in riding lessons at an equestrian riding school. Hematology and serum chemistry samples were obtained before the initial lesson and after the last lesson of the day. The post-exercise results showed that packed cell volume, white blood cell, red blood cell, hemoglobin, and total protein levels increased significantly (p < 0.05). Serum Na+ also increased significantly (p < 0.01), but serum Ca++ decreased significantly (p < 0.01). Creatinine kinase, aspartate amino transferase, gamma glutamyl transferase, blood urea nitrogen, creatinine, and bilirubin levels increased significantly (p < 0.05), but the glucose level decreased significantly (p < 0.05). Furthermore, the serum cortisol hormone level increased significantly (p < 0.01). The results suggest that participating in riding lessons three times a day may result in various physiological changes, indicating the presence of exercise-related stress in riding ponies.

  • McW의 간 해독효과를 조사하였다. 실험군은 총 4개군 즉, 증류수급여군으로 대조군(DC)과 증류수를 3주간 섭취케 한 후 희생직전에 BB를 처리한 군(DB), McW 급여군으로는 McW 대조군(MC)과 McW를 3주간 섭취케 한 후 희생직전에 BB를 처리한 군(MB)의 4개 군으로 구분하였다. DC군과 MC군의 혈청 ALT 및 AST 활성은 뚜렷한 차이를 보이지 않았으나 MB군에서는 DB군에 비하여 유의하게 낮았다. 간 AH 활성은 모든 실험군에서 유의한 변동이 없었으나 GST 활성은 MC군이 DC군에 비하여, MB군이 DB군에 비하여 각각 높았다. 간 조직의 LPO 함량은 DC 및 MC군이 유사하였으며, DB 및 MB군 모두 DC군보다 유의하게 증가하였으나 그 증가율은 MB군이 DB군에 비하여 낮았다. McW의 전자공여능은 DW에 비하여 유의하게 높았다. 이상의 결과 McW는 간 해독효소의 일종인 GST의 활성을 증가시킴과 동시에 McW의 지속적인 섭취에 의한 항산화 작용에 의해 해독작용을 나타내는 것으로 생각되나 추후 계속적인 연구검토가 행해져야할 것이다.

  • An aqueous extract of oriental herbal composition named Onchengyeum and curcumin, an antioxidant isolated from turmeric (Curcuma Zonga L.) reduced hepatotoxicity induced by carbon tetrachloride ($CCI_4$). Improved liver function was observed by measuring the activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), blood urea nitrogen (BUN), creatinine (CRE), total cholesterol (T-CHO), triglyceride (TG), low density lipoprotein cholesterol (LDL-CHO), high density lipoprotein cholesterol (HDL-CHO), total protein (TP), albumin (ALB) and total bilirubin (BIL) in serum. Hepatic parameters monitored were levels of cholesterol (CHO), triglyceride (TG), and malondialdehyde (MDA) and activities of cytochrome P450 (CYP), NADPH-CYP reductase, superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), glutathione S-transferase (GST), glutathione reductase (GR), and glutathione peroxidase (GPx). The histopathological examination showed that the treatment of Onchengyeum and curcumin relieved the ballooning degeneration of hepatocytes which had been generated by $CCI_4$. The results suggested that hepatoprotective effects of Onchengyeum and curcumin possibly are due to their promising antioxidative activity.

  • Automated system to analyze liver function test results is presented based on fuzzy logic knowledge. Clinician's knowledge and experience was first expressed in linguistic terms fol- lowed by conversion to numerical values to create membership functions of disease possibility for each test item and liver disease. Membership functions were then compensated for different relative importances of test items. Liver diseases considered were acute viral hepatitis (AVH), chronic persistent hepatitis(CPH), chronic active hepatitis(CAH), and liver cirrhosis(LC), Liver function test results of alanine aminotransferase(ALT), aspartate amino- transferase(AST) , glutamate dehydrogenase(GDH), ornithine carbamyltransferase(OCT) , ALT/AST, and 10* GDH/ALT in 218 patients were analyzed by the present system, welch resulted in 80% accuracy. AVH and CAH showed the highest 93 % and the lowest 58% ac- curacies, respectively, which was similar to the clinician's expectation. The simple mathemat- ical formulation of the present system would enable an easy implementation in commercial analysis instruments. Also, the identical fuzzy logic can be applied to similar diagnostic envi- ronments in general.
