  • This study was performed to investigate the effect of fermented Hovenia dulcis Thunb fruit water extract on biomarkers for acute (a) ethanol-induced hangover and chronic (c) ethanol-induced liver injury in rats. For acute ethanol-induced hangover, the rats were administered distilled water (D.W., 10 mL/kg body wt.), Hovenia dulcis Thunb fruit water extract (HWE, 400 mg/10 mL/kg body wt.) and fermented HWE (FHWE, 400 mg/10 mL/kg body wt.), respectively, before 40% ethanol (5 g/kg body wt.) was administered. For chronic ethanol-induced liver injury, the rats were randomly divided into the normal control (cNC), ethanol (cET), cET-HWE and cET-FHWE groups. The cNC and cET groups were administered D.W. (10 mL/kg body wt.) before 40% alcohol (5 g/kg body wt.) was administrered for 21 days. The cET-HWE and cET-FHWE groups were administered HWE (400 mg/10 mL/kg body wt.) and FHWE (400 mg/10 mL/kg body wt.), respectively before 40% ethanol (5 g/kg body wt.) administration for 21 days. For acute ethanol-induced hangover, the serum alcohol and acetaldehyde concentrations were more significantly reduced in the aHWE and aFHWE groups than in the aET group. Moreover, the effect of FHWE was greater than that of HWE. For chronic ethanol-induced liver injury, the serum ethanol, acetaldehyde, ${\gamma}$-glutamyl transpeptidase (${\gamma}$-GTP) levels and the hepatic lipids concentration more significantly dropped in the cET-HWE and cET-FHWE groups than in the cET group. The FHWE administration showed faster recovery of the serum glucose concentration than in the cET and cET-HWE groups. The body weight reduction tended to normalize in the cET-HWE and cET-FHWE groups, which is ideal for chronic ethanol administration. These results suggest that FHWE has a protective effect against ethanol-induced liver damage, as evidenced by its ability to lower the serum ethanol and acetaldehyde concentrations after alcohol administration, and by its ability to decrease the level of ${\gamma}$-GTP and hepatic lipids. FHWE also elevated serum glucose concentration. Therefore, FHWE is effective in reducing ethanol-induced hangover and can play a beneficial role in the treatment of ethanol-induced liver damage as well as body weight reduction.

  • Alcoholics increased susceptibility to microbial infection that is associated with decreased immunity. but there has been little experimental evidence to support alcoholics-induced increase of microbial infection directly in non-specific immunity. Therefore, we were used the method of phagocytic-plaque including all the stimulating factors for the phagocytosis, subtypes of lymphocytes and T-lymphocyte proliferation. The experimental groups were divided into 3 groups: (1) alcoholics who were hospitalized less than 1 week (newly hospitalized alcoholics), (2) alcoholics who were hospitalized more than 2 weeks (old hospitalized alcoholics), (3) healthy blood donors. We have studied 98 alcoholics and 35 healthy blood donors and control groups. A physician has checked the biological markers and diagnosed the body-condition alcoholics. The immunity and non-specific immunity on the alcoholics were analyzed by using the simultest kit and flow cytometry. Proliferation of the lymphocytes was analyzed by the phytohemmagglutinine mitogen. Phagocytosis and migration properties of leukocytes were identified on the layer formed by Staphylococcus aureus Cowan I strain. Biological markers of alcoholics and control groups, by such as blood glucose, ${\gamma}$-glutamyl transpeptidase and mean corpuscular volumes of red blood cells, were determined by biochemical and hematological methods. Compared with control groups, cluster of differentiation (CD)3+, CD8+ and CD19+ in alcoholic were more decreased except CD4+/CD8+ ratio. Proliferation of the T-lymphocytes, phagocytosis and migration properties of the leukocytes in alcoholics were decreased compared with those of control groups. According to the results observed in our experiment, they can be summerized as follows: 1, Cellular, humoral and non-specific immunities, are markedly decreased in alcoholics than those in control groups. 2. It is inferred that Phagocytic plaque formation is a very useful method to evaluate phagocytosis and migration properties of the alcoholic leukocytes 3. It is thought that the subtypes of lymphocytes, especially CD4+/CD8+ ratio, are essential methods to analyzed the alcoholic immunity. 4. Specific and non-specific immunity on the old hospitalized alcoholics was slightly increased, which depends upon the alcoholic medication.

  • In order to determine the effects of annexing bile extracts of bears on the anti-fibrotic effect of Injinhotang. Mix compound of Injinhotang and bile extracts of bears were administered to the carbon tetrachloride ($CCl_4$)-induced cirrhotic rats during 20 days and the changes of serum levels of GOT (glutamic-oxalacetic transaminase), GPT (glutamic pyruvic transaminase), LDH (lactate dehydrogenase), ALP (alanine phosphatase), GGT (gamma glutamyl transpeptidase) and T-BIL (total bilirubin) were monitored with comparison to the results of Injinhotang administered group. The results were summarized as follows. 1. A significant (p<0.01) increase of serum GOT levels were observed in control group compared to those of normal group but these increased levels were dramatically decreased in Injinhotang and Injinhotang with Fel Ursi-administered group. In addition, a significant (p<0.05) increase were also detected In Injinhotang with Fel Ursi-administered group compared to that of Injinhotang-administered group. 2. A significant (p<0.01) increase of serum GPT levels were observed in control group compared to those of normal group but these increased levels were dramatically decreased in Injinhotang and Injinhotang with Fel Ursi-administered group. Although significances were not recorded, increase of serum GPT levels were also detected in Injinhotang with Fel Ursi-administered group compared to that of Injinhotang-administered group. 3. A significant (p<0.01) increase of serum LDH levels were observed in control group compared to those of normal group but these increased levels were dramatically decreased in Injinhotang and Injinhotang with Fel Ursi-administered group. Although significances were not recorded, increase of serum LDH levels were also detected in Injinhotang with Fel Ursi-administered group compared to that of Injinhotang-administered group. 4. A significant (p<0.01 or p<0.05) increase of serum ALP levels were observed in control group compared to those of normal group but these increased levels were dramatically decreased in Injinhotang and Injinhotang with Fel Ursi-administered group. In addition, a significant (p<0.05) increase were also detected in Injinhotang with Fel Ursi-administered group compared to that of Injinhotang-administered group. 5. A significant (p<0.01) increase of serum GGT levels were observed in control and Injinhotang-administered group compared to those of normal group but these increased levels were dramatically decreased in Injinhotang with Fel Ursi-administered group. 6. A significant (p<0.01) increase of serum T-BIL levels were observed in control group compared to those of normal group but these increased levels were dramatically decreased in Injinhotang and Injinhotang with Fel Ursi-administered group. Although significances were not recorded, increase of serum T-BIL levels were also detected in Injinhotang with Fel Ursi-administered group compared to that of Injinhotang-administered group. In conclusion, it is considered that bile extract of bears has some additional effect to the anti-fibrotic effect of Injinhotang but to know the exact mechanism of suitable dose and duration of administration, further studies such as pharmacokinetics and dose-dependent pharmacological studies were needed

  • The present study was performed to elucidate the recovery effect of needle-acupuncture (needle-AP) and moxibustion treatments at Gan Shu (BL18) on $CCl_4$ induced hepatic injury in dogs, Total 9 clinically healthy experimental dogs (1 to 2 years old, 2.3-5.3kg body weight) were divided into control (3 dogs), needle-AP (3 dogs) and moxibustion (3 dogs) groups, respectively. Hepatic iniw was induced by intraperitoneal injection with $CCl_4$ (olive oil : $CCl_4=1:1,\;1ml/kg$, once/day). As far the treatments in each group, control group was not treated at all after induction of the hepatic injury till the end of experiment. Needle-Af group was treated by AP at BL18 (once/day, 20 minutes) from the next day of induction of the hepatic injury for 11 days. Moxibustion group was also treated with commercial moxa at BL18 (once/day, 20minutes) for 11days. The changes of the serum alanine transaminase(ALT), aspartate transaminase(AST) and gamma glutamyl transpeptidase (GGT) activities were investigated on pre, 0, 1, 3, 5, 7 and 11 days after hepatic injury, respectively. Histopathological changes were also investigated in the liver tissues on day 11 in experimental and control groups. The results obtained in the present study were as follows. In needle-AP group, they showed significant lower values on the 1st (p<0.05) and $3^{rd} day (p <0.05)$ in serum ALT activities, and the $11^{th}$ day in serum GGT activities, compared with those of control group, respectively. However, the significances were not detected in serum AST activities of needle-AP group by comparison with those of control group. In moxibustion group, they showed significant low values on the $1^{st}(p<0.05)$, 3rd day (p<0.05) and $5^{th}$ day (p<0.05) in serum ALT activities, compared with those of control group, respectively. However, significances were not detected in serum GGT and AST activities of moxibustion group by comparison with those of control group. Among the experimental groups, the significant low values were found on $1^{st}\;and\;3^{rd}$ day in serum ALT activities (p<0.05), and $3^{rd}\;and\;5^{th}$ day in serum GGT activities (p<0.05) in needle-AP group, compared by those of moxibustion group, respectively. In addition, the marked recovery findings of histopathological changes in experimental groups were found, compared by those of control group: mild vacuolar degeneration and necrosis findings in needle-AP group, and moderate vacuolar degeneration and necrotic findings in moxibustion group were found, in contrast to severe changes such as accumulation of bile juice, vacuolar degeneration and necrotic findings observed in control group. In conclusion, needle-AP and moxibustion treatments at BL-18 were effective for the recovery for $CCl_4$ induced hepatic injury and needle-AP was more effective than that of moxibustion in dogs.
