Objectives: Haeganjeon(HGJ) has been used for the treatment of liver disease in traditional medicine. The present study was carried out to evaluate the antioxidant and protective effects of HGJ extract on oxidative damage of hepatocytes by tert-butyl hydroperoxide(t-BHP). Methods: In the linoleic acid water-alcohol system, the levels of lipid peroxide(LPO) were determined by TBA method. The scavenging effect of HGJ on ${\alpha},{\alpha}-diphenyl-{\beta}-picrylhydrazyl$(DPPH) radical was determined according to the method of Hatano. In the Fenton system(ferrous ion reaction with hydrogen peroxide), the levels of hydroxyl radical induced LPO in rat liver homogenate were determined according to the method of TBA. Inhibitory effect of HGJ on superoxide generation was measured by xanthine-xanthine oxidase system. In order to evaluate antioxidative activity of HGJ in the liver cell, cultured normal rat liver cells(Ac2F) were prepared and incubated with or without HGJ. After 18hr, cells placed in DMEM medium without serum, and then incubated with 1mM tert-butyl hydroperoxide(t-BHP) for 2hrs. Viable cells were detected by MTT assay. Conclusions: In the linoleic acid autoxidation system, HGJ extract significantly inhibited the time course of the lipid peroxidation. These effects were similar to those of BHA HGJ extracts showed about 70% scavenging effect on DPPH radical. And HGJ extract inhibited the lipid peroxide formation in rat liver homogenate induced by hydroxyl radical derived from Fenton system. In addition, HGJ extract protected the cell death induced by t-BHP and significantly increased cell viability in the normal rat liver cell. These result indicated that HGJ extract might playa protective role against oxidative hepatic cell injury by means of free radical scavenger.

Purpose : Investigate the effects of Haeganjeon water extract (HGJ) on immobilization-stress or cold-stress in C57BL/6J mice. Methods : Male C57BL/6J 30 mice of weighting 18${\pm}$2g, were divided into sixs groups including the immobilization-stress group(5heads), after immobilization-stress HGJ oral administration(500mg/kg) groups(5heads), cold-stress group(5heads) and after cold-stress HGJ oral administration(500mg/kg) groups(5heads). then we observed changes in the serum histamine and corticosterone level and changes immune system. Results : HGJ decreased the serum level of histamine and corticosterone increased by immobilization-stress or cold-stress. HGJ inhibited the release of histamine from mast cells. In addition, HGJ enhanced the cell viability of thymocytes decreased by immobilization-stress or cold-stress and decreased DNA fragmentation of thymocytes increased by immobilization- stress or cold-stress. Also, HGJ increased the cell viability of splenocytes decreased by cold-stress and decreased DNA fragmentation of splenocytes increased by cold-stress. HGJ decreased the population of thymic CD4+ cells increased by immobolization-stress. HGJ increased the population of B220+ cells decreased by immobilization-stress and decreased the population of Thy1+ cells increased by immobilization-stress. Also, HGJ decreased the population of splenic CD4+ cells increased by immobolization-stress. HGJ enhanced the production of ${\gamma}-interferon$ decreased by immobilization-stress or cold-stress and increased the production of interleukin-4 decreased by immobilization-stress. Furthermore, HGJ enhanced the phagocytic activity decreased by immobilization-stress or cold-stress and enhanced the level of nitric oxide decreased by immobilization-stress or cold-stress. Conclusion : HGJ may be useful for the prevention and treatment of stress via suppression of serum histamine and corticosterone level and enhancement of immune response.

The purpose of this study is to observe the effect of Nanganjeon on serum reaction in $CCl_4$ treated rats. In this study, the experimental rats divided four group(Control group, $CCl_4$ group, Haeganjeon group, and Sample group) : Under the same condition, control group were administered water, sample group were administered Nanganjeon for 7days. And then, both $CCl_4$ group and sample group were injected to abdomen with $CCl_4$ for 1days. The change of GOT, GPT, ALP, LDH, and bile acid activity in blood serum. The obtained results are summarised as follows : 1. In the change of SGOT, SGPT contents, as compared with control group, sample group was significantly decreased. 2. In the change of serum ALP contents, as compared with control group, sample group was significantly decreased. 3. In the change of serum bile acid contents, as compared with control group, sample group was significantly decreased. 4. In the change of serum LDH contents, as compared with control group, sample group was significantly decreased.

Objective: To investigate the protective effects of Haeganjeon on a thioacetamide (TAA)-induced liver fibrosis mouse model and to determine the Haegan-jeon signaling pathway. Methods: Mice were randomly divided into 4 groups: Normal group (Nor), TAA-induced liver fibrosis group (Con), TAA-induced liver fibrosis group administered 50 mg/kg silymarin (S50), TAA-induced liver fibrosis group administered 200 mg/kg Haegan-jeon (H200). The liver fibrosis mouse model was established by intraperitoneal injection with TAA three times a week for 8 weeks. During the 8 weeks, mice were orally administered silymarin and Haegan-jeon every day. At the end of the study, serum was collected to measure the levels of AST, ALT, ammonia, and myeloperoxidase (MPO). Liver tissue was harvested and analyzed by western blotting and Masson's trichrome staining. Results: Administration of Haegan-jeon suppressed the increase in serum levels of AST, ALT, ammonia, and MPO due to TAA-induced liver fibrosis. Compared to the Con group, the H200 group showed increases in antioxidant-related factors (Nrf2, HO-1, catalase, and GPx-1/2) and decreases in inflammatory-related factors (NF-κB p65, p-IκB-α, Cox-2, iNOS, TNF-α, and IL-1β) in western blots. The H200 treatment inhibited the expression of α-SMA and Collagen I. Conclusions: Haegan-jeon showed a hepatoprotective effect induced by activation of antioxidant-related factors, such as Nrf2, and it regulated the inflammation response by suppression of NF-κB.
