Galgeun-tang (GGT) has been a great source for treating cold diseases in the folk medicine recipe. Carbon tetrachloride ($CCl_4$) is one type of hepatotoxin that can eventually cause liver injury. During the experiment, we first studied the protective effects of GGT against $CC_4$-induced hepatotoxicity. GGT was pretreated for 3 h, and 1% $CCl_4$ was added to mouse primary liver cells. After 4 h, ROS generation and expression of antioxidant enzymes (catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx)) were analyzed by FACS and real time PCR. Also, the activities of ALT and LDH were measured using cultured medium. The hepatic levels of TNF-alpha and iNOS, which are related to inflammation and stress response gene, HSP72 and HO-1 were analyzed by PCR or real time PCR. Liver tissues were analyzed by HE stain. From the observation, we discovered that GGT treatment protects $CCl_4$-induced hepatotoxicity, and that GGT pretreatment decreases ROS generation, TNF-alpha and iNOS expression. However, gene expression of CAT, SOD, GPx, HSP72 and HO-1 were increased by GGT. These results lead to the conclusion that GGT has protective effects against $CCl_4$-induced hepatotoxicity.

Inonotus obliquus is one of the immune-regulatory substances and is recognized to play the role in the metabolic process of inflammation, allergy and immuntiy. The purpose of this study was to evaluate the effects of water extracts of Inonotus obliquus (IOW) on the liver lymphocyte immune function in the Sprague-Dawley male rats treated with carbon tetrachloride ($CCl_4$) to induce liver damage. Rats were fed with each experimental diet and water for 4 weeks. We found that effects of IOW on interferon-gamma (IFN-$\gamma$), signal transducer and activator of transcription 1 (STAT1), phospho-signal transducer and activator of transcription 1 (pSTAT1) and GATA-binding protein 3 (GATA-3) were decrease in vivo. Interleukin-4 (IL-4), STAT6, pSTAT6 and T-box expressed in T-cells (T-bet) decreased significantly lower in $CCl_4$+IOW group than the $CCl_4$ group. Our data indicated that cytokine protein production were increased in $CCl_4$ group and $CCl_4$+IOW group. As a result of this study, we assume that IOW fed could regulate the immuno-modulating functions through regulate the cytokine production capacity activated by liver damage.

Several compounds and extracts isolated from a brown alga, Ishige (I.) okamurae, exhibit anti-oxidant and anti-inflammatory effects. The present study investigated whether the ethyl acetate (EtOAc) fraction of I. okamurae (EFIO) could ameliorate carbon tetrachloride ($CCl_{4}$)-induced hepatotoxicity in rats. Sprague-Dawley rats were intraperitoneally (i.p.) administered with EFIO at 10 or 50 mg/kg per day for 2 consecutive days before $CCl_{4}$ injection (3.3 mL/kg, i.p.). Twenty four hours later, the rats were anesthesized with diethyl ether and dissected. Pretreatment with EFIO significantly reduced the increased serum levels of alanine aminotransferase and aspartate aminotransferase in $CCl_{4}$-treated rats. Pretreatment with EFIO also significantly inhibited the reduced activities of superoxide dismutase and catalase in the $CCl_{4}$-injured liver. Histopathological evaluations showed that hemorrhage, hepatocyte necrosis, inflammatory cell infiltration, and fatty degeneration induced by $CCl_{4}$ treatment were ameliorated by the administration of EFIO. Additionally, liver immunohistochemical analyses revealed the marked reduction in ED1-positive monocyte-like macrophages in EFIO-pretreated rats given $CCl_{4}$. These results suggest that EFIO ameliorates $CCl_{4}$-induced liver injury, possibly through the inhibition of oxidative stress.

Opuntia ficus-indica is widely used as folk medicine for burned wound, edema and indigestion, etc. After the adaptation of rats for seven days, OF (200mg/kg) was administered into rats intraperitoneally every day for two weeks. On the 14th day, $3.3m\ell$ of $CCl_4$ (50% $CCl_4$ : Olive oil = 1 : 1) was treated to rats and on the 15th day, they were operated. We measured the levels of total cholesterol, HDL-cholesterol, LDL-cholesterol, total lipid and triglyceride (TG) in serum and Malondialdehyde (MDA) in liver tissue. Opuntia ficus-indica and $CCl_4$-treated group (OFC) significantly decreased lipid peroxidation by 32.6% compared to $CCl_4$-treated abnomal group (CTA). Total lipid and TC of OFC administered group were lower than those of CTA group. Cholesterol levels showed significant effect in OFC group. Total cholesterol and LDL-cholesterol in OFC administered group were decreased by 12.7% and 17.4%, respectively, compared to those of CTA group. HDL-cholesterol in OFC administration group was increased by 19.7% compared to CTA group. This finding suggests that lipid peroxidation was inhibited in the significant level when $CCl_4$-induced rats were treated with OF. Based on this analysis, further study to identify the active components in this sample is warranted.

Cuscuta chinensis Lamak (CCL) has traditionally been used in Korea to treat sexual disorders and skin problems. The aim of the present study was to investigate the effects of CCL extract on surgical injury-induced ischemia in the hind limbs of mice. Specifically, female C57BL/6 mice were ovariectomized, and their hind-limb vessels were ligated with surgical silk (6-0) and excised. CCL (150 or 450 mg/kg/BW) was then administered to the mice for 3 weeks, and the blood flow rate was evaluated using a laser Doppler system at -7, 0, 7, 14 and 21 days following hind-limb ischemia. The serum expression profiles of angiogenic and inflammatory mediators were measured using an antibody array, and the transcript levels were reverse transcription-quantitative polymerase chain reaction. The rate of hind limb blood flow was normalized to non-ischemic lesions and revealed to be markedly elevated at 14 and 21 days following ischemia when compared with the vehicle group. The density of capillaries in the hind limbs was also significantly increased following treatment with CCL in a dose-dependent manner. In addition, the transcriptional expression of angiogenetic factors were upregulated, whereas that of inflammatory cytokines were downregulated. Finally, vascular endothelial cell migration and tube formation were evaluated in vitro using human umbilical vein endothelial cells (HUVECs) and identified to be significantly increased following treatment with CCL. Overall, the results of the present study indicate that CCL extract exhibits therapeutic potential for the treatment of hind-limb ischemia as it promotes peripheral angiogenic and anti-inflammatory effects in mice.

The role of iron as a possible pathogenic factor in the Infection of V. vulnificus was examined in thins paper The effects of iron and $CCl_4$ on the growth of V. vulnificus in human and rabbit sera were also done. Injection of iron to mice resulted in a lowering of the 50% lethal dose and in a reduction in the time of death postinfection. Serum iron levels were also elevated by damaged livers with infections of $CCl_4$- The inoculum size required to kill these mice was directly correlated with serum iron Irvels. Iron appeared to be the limiting factor In the ability of thins organism to survive or grow in mammalian sera. These results, both in vitro and In vivo, provided strong evidence that iron may play a major role In the pathogenesis of V. vulnificus.

Objectives: This study was designed to investigate protective effects of Sayeoksanhap-Pyeongweisan-Gamibang(SPG) on hepatological changes in rats damaged by $CCl_4$. Methods : We investigated the effects of SPG on hepatological changes in terms of AST/ALT levels, Total cholesterol, HDL-cholesterol and triglyceride in serum and lipid peroxidation in rat liver. Results : Combination treatment with acupuncture and oral administration of SPG decreased AST and ALT in serum. Combination treatment also decreased lipid peroxidation in liver and triglyceride in serum. In addition, HDL-cholesterol in serum was increased significantly by combination treatment. Contrary, level of total cholesterol was not changed by combination treatment. Conclusion : These results suggest that Combination treatment with acupuncture and oral administration of SPG was useful to protect liver against $CCl_4$ by its antioxidant action in liver tissues.

This study was carried out to investigate effect of lipid metabolism in Viscum album lectin on rats. The lectin was purified by sepharose 4B affinity chromatography and gel filtration using sephadex G-150 with plant material from Viscum album collected in Mt. Duk Yui. After 72 h of $CCl_4$ injection (in olive oil, 1:1, 2 mg/kg) there was a significant increase in serum total cholesterol and triglycerige levels relative to the control group. However, treatment of both Viscum album and purified lectin were significantly decreased lipid parameters against the $CCl_4$-induced. Histological observation basically supported the result obtained from serum lipid assay. The livers of rats challenged with $CCl_4$ produced a marked increase of cytoplasmic vacuoles in number, while the number of necrotic cells and swollen hepatocytes did not change significnatly. Rats administered olive oil alone did not alter the normal hepatic architecture. Histological observation of the liver section in rats treated 72 h with either Viscum album purified lectin or $CCl_4$-induced liver lipogenesis showed decreased numbers of cytoplasmic vaculoes and necrotic cells. The normal hepatic architectural pattern was observed in Hematoxylin-eosin stain. These results suggest that Viscum album lectin has a possible protective effect of lipid metabolim in rats.
