  • Objectives : This study was performed to investigate the anti-fibrogenic effect of Injinchunggan-tang on cultured rat hepatic stellate cells. Materials and Methods : Hepatic stellate cells(HSC-T6) were treated with various concentrations of Injinchunggan-tang extract for 24, 48, and 72 hours. The extraction was done with distilled water. After the treatment, cell viability, proliferation, procollagen levels and the mRNA of the TIMP-1, TIMP-2, and ASMA were measured by using MTT assay. BrdU assay, procollagen type I C-peptide EIA kit and RT-PCR. Results : The proliferation, mRNA expression and synthesis of collagen of the hepatic stellate cells were inhibited by Injinchunggan-tang treatment in a dose-dependent manner. This indicates the prescription has inhibitory effect on fibrogenesis of the liver by regulating the fibrogenesis associated genes in transcription. Cell viability was inhibited in time- and dose-dependent manners. It seemed that the drug should be used with sufficient dose to acquire treatment effect. Conclusion : These results suggest that Injinchunggan-tang is beneficial in the treatment of cirrhotic patients as well as for the patients with chronic hepatitis.

  • 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.

  • Idiopathic non-cirrhotic portal hypertension (INCPH) is a disease with an uncertain etiology consisting of non-cirrhotic portal hypertension and portal pressure increase in the absence of liver cirrhosis. In INCPH, patients exhibit normal liver functions and structures. The factors associated with INCPH include the following: Umbilical/portal pyremia, bacterial diseases, prothrombic states, chronic exposure to arsenic, vinyl chloride monomers, genetic disorders, and autoimmune diseases. Approximately 70% of patients present a history of major variceal bleeding, and treatment relies on the prevention of complications related to portal hypertension. Autoimmune disorders associated with INCPH are mainly systemic sclerosis, systemic lupus erythematosus and rheumatoid arthritis. To the best of our knowledge, a case of ankylosing spondylitis (AS) associated with INCPH has not been reported thus far. Therfore, we report our experience of a patient with AS accompanied by INCPH, who showed perisplenic varices with patent spleno-portal axis and hepatic veins along with no evidence of cirrhosis on liver biopsy, and provide a brief literature review.

  • Purpose: We investigated early postoperative morbidity and mortality in patients with liver cirrhosis who had undergone radical gastrectomy for gastric cancer. Materials and Methods: We retrospectively reviewed the medical records of 41 patients who underwent radical gastrectomy at the Chonnam National University Hwasun Hospital (Hwasun-gun, Korea) between August 2004 and June 2009. There were few patients with Child-Pugh class B or C; therefore, we restricted patient selection to those with Child-Pugh class A. Results: Postoperative complications were observed in 22 (53.7%) patients. The most common complications were ascites (46.3%), postoperative hemorrhage (22.0%) and wound infection (12.2%). Intra-abdominal abscess developed in one (2.4%) patient who had undergone open gastrectomy. Massive ascites occurred in 4 (9.8%) patients. Of the patients who underwent open gastrectomy, nine (21.9%) patients required blood transfusions as a result of postoperative hemorrhage. However, most of these patients had advanced gastric cancer. In contrast, most patients who underwent laparoscopic gastrectomy had early stage gastric cancer, and when the confounding effect from the different stages between the two groups was corrected statistically, no statistically significant difference was found. There was also no significant difference between open and laparoscopic gastrectomy in the occurrence rate of other postoperative complications such as ascites, wound infection, and intra-abdominal abscess. No postoperative mortality occurred. Conclusions: Laparoscopic gastrectomy is a feasible surgical procedure for patients with moderate hepatic dysfunction.

  • Lamivudine, an oral nucleoside analogue, effectively inhibits hepatitis B virus replication and reduces hepatic necroinflammation in patients with chronic hepatitis B. Although lamivudine has shown a promise in patients with chronic hepatitis B, a long-term data on Korean patients with hepatitis B are lacking. The purpose of this study is to evaluate the effects and safety of 52-week lamivudine therapy in Korean patients with chronic hepatitis B, A total of twenty-nine patients (27 male and 2 female) who had received 100 mg of oral lamivudine daily for 52 weeks were evaluated, retrospectively. The mean age of 29 patients in the study group was 37.7 $\pm$ 8.9 years (range 19-54). Pretreatment HBV PCR and HBsAg were positive in all 29 patients, and HBeAg were positive in 25 patients (86%). The serum HBV DNA of 28 patients (97%) significantly fell to undetectable levels (<5 pg/ml) within 12 weeks of therapy and it remained undetectable in 24 patients (83%) by the end of 52-week therapy (p<0.001). Mean serum ALT levels of 29 patients declined to the normal range within 12 weeks and remained within the normal range during the evaluative period (p<0.05). The proportions of patients with HBeAg seroconversion (loss of HBeAg, development of antibody to HBeAg, and undetectable HBV DNA) were 42% after 52-week therapy. The differences of response to lamivudine therapy in HBeAg- positive and HBeAg-negative patients were negligible (p>0.05). Furthermore, the study showed that pretreatment serum HBV DNA and ALT levels have no effect to the efficacy of lamivudine therapy (p>0.05). Further comparison of lamivudine's efficacy showed that lamivudine is just as efficacious in patients with cirrhosis as without cirrhosis (p>0.05). In conclusion, lamivudine is an effective and safe therapy for the treatment of chronic hepatitis B in Korean patients.

  • Artemisia Iwayomogi Compositae) has been used clinically for jaundice, hepatitis, liver cirrhosis etc. The purposes of present study were to examine pharmacological effects of Artemisia Iwayomogi water extract(AIWE) on biochemical parameters (activities of ALP and LAP, contents of glucose, total bilirubin, total protein and albumin in serum, A/G ratio, and levels of hepatic glycogen) against hepatic injury by carbon tetrachloride($CCl_4$) in rats. The results were as follows ; 1. Increased ALP activities by $CCl_4$ were very significantly(p<0.001) decreased in AIWE posttreatment groups at 72 hours and significantly(p<0.05) decreased in AIWE pretreatment groups at 72 hours. Increased LAP activities by $CCl_4$ were significantly (p<0.05) decreased in AIWE posttreatment groups at 72 hours. A little increased total bilirubin contents by $CCl_4$ were very significantly (p<0.001) decreased in AIWE posttreatment groups at 24, 48 and 72 hours. 2. Increased glucose contents by $CCl_4$ were decreased in AIWE posttreatment groups. Decreased hepatic glycogen levels by $CCl_4$, were significantly (p<0.05) increased in AIWE posttreatment groups at 48 and 72 hours. 3. Decreased total protein contents by $CCl_4$ were significantly (p<0.05) increased in AIWE posttreatment groups at 48, 72 hours. Decreased albumin contents by $CCl_4$ were increased in proportion to numbers of AIWE treatments in AIWE pre- and posttreatement groups. Decreased A/G ratios by $CCl_4$ were significantly (p<0.05) increased in AIWE posttreatment groups at 48 hours. In conclusion, AIWE did not affect normal liver function and had hepatoprotective effects rather than direct preventive effects to $CCl_4$-induced cholestasis, damages in metabolisms of glucose, protein and bilirubin.

  • Objectives : This study was performed to investigate the anti-fibrogenic effect of Angelica Gigantis Radix on cultured rat hepatic stellate cells. Materials and Methods : Hepatic stellate cells(HSC-T6) were treated with various concentrations of Angelica Gigantis Radix extract for both 24 and 48 hours. The extraction was done either with distilled water or 80% EtOH. After the treatment, cell viability, cell proliferation, procollagen production and the mRNA expression of the ASMA, TIMP1, TIMP2, procollagen Type 1a2, and Cytokine IL-6 production were measured by using MTT assay, BrdU assay, RT-PCR, procollagen Type I C-peptide EIA and IL-6 ELISA assay. Results : The cell viability treated with water extraction was significantly increased, but there were no significant changes treated with 80% EtOH extraction. The cell proliferation treated with water extraction decreased only in the 24 hours group, while there were significant decreases either in the 24 and 48 hours groups treated with 80% EtOH extraction. The mRNA expressions of the ASMA, TIMP2 and procollagen 1a2 decreased in a concentration-dependent manner in the 48 hours group. Procollagen production decreased in a concentration-dependent manner in both the 24 and 48 hours groups. Cytokine IL-6 production increased in a concentration-dependent manner in both the 24 and 48 hours groups. Conclusion : These results suggest that Angelica Gigantis Radix is beneficial in the treatment of cirrhotic patients as well as for patients with chronic hepatitis.

  • Hepatic fibrosis refers to the scarring of liver tissue, often resulting from chronic liver injury or inflammation. It is characterized by excessive deposition of extracellular matrix proteins, impairing liver function and potentially progressing to cirrhosis if left untreated. To improve the liver functions, Cordyceps militaris, a species of parasitic fungus known for its medicinal properties, is used in the form of extract. It has been traditionally used in Chinese medicine to boost energy, improve stamina, and support overall health. In this study, we investigated the hepatoprotective effects of Cordyceps militaris extract powder in a liver injury model induced by hepatic fibrosis. Sprague-Dawley (SD) rats were administered Dimethylnitrosamine (DMN) to induce liver injury, and the hepatoprotective effects of Cordyceps militaris extract powder intake were assessed by comparing changes in liver enzyme levels and histological observations. Rats injected with DMN were orally administered Cordyceps militaris extract powder at doses of 0, 125, 250, and 500 mg·kg-1·day-1 for three weeks. After three weeks of treatment, no significant differences were observed in hematological, clinical chemical, organ weight, gross examination, or microscopic examination between the DMN-alone group and the Cordyceps militaris extract powder-treated group. In conclusion, hepatoprotective effects against DMN-induced liver injury in SD rats treated with Cordyceps militaris extract powder were not observed under this study condition.
