  • Excessive endogenous endotoxin, especially lipopolysaccharide (LPS) reflux from gastrointestinal (GI) tract to the liver tissue is one of the most serious reasons of severe and acute liver injury which is mainly mediated by Kupffer cell activations. However, there is no clear molecular clues to explain the exact pathophysiological mechanism and effective drugs available till nowadays. We aimed to comprehend the pathophysiological features of LPS-induced liver injury and evaluate the efficacies of potential therapeutic drug, Ga-mi-Yuk-Mi-Jihwang-Tang (GYM), which is composed of herbal plants. GYM remarkably caused to normalize hepatic inflammation and oxidations against LPS-induced liver injury by evidence of serum liver enzymes, histopathological analysis, both hepatic protein and gene expression levels of pro-inflammatory cytokines, nitric oxide levels, and hepatic tissue levels of reactive oxygen species (ROS) levels, malondialdehyde (MDA), and 4-hydroxyneoneal, respectively. To assess molecular events in the hepatic tissue, we further found hepatic Sirtuin6 (Sirt6) levels were considerably depleted by LPS injection with aberrant alterations of Nrf2/HO-1 signaling pathways, whereas administration with GYM notably exerted to normalize these abnormalities. Our results exhibited that GYM would be one of target drug to diminish hepatic inflammation as well as oxidative stress by regulation of hepatic Sirt6 levels.

  • The effects on the radical scavenging activities and hepatic lipid levels in rats fed a high-fat diet (HFD) in the 70% ethanolic extract from Acer tegmentosum Maxim (ATM) were evaluated. Total phenol content of ATM was 168.60 mg catechin/g in the 70% ethanolic extract of Acer tegmentosum. The DPPH and ABTS radical scavenging activities were 18.32 mM TE/g and 32.25 mM TE/g, respectively. Food efficiency ratio was lower significantly in supplemented group with 150 mg/kg BW/day during 5 weeks (HFD+ATM) compared to HFD. Total cholesterol and triglyceride contents in liver tissue of HFD+ATM were lower significantly compared to those of the HFD. Supplementation of ATM significantly decreased lipid peroxide contents and increased radical scavenging activity in the liver tissue compared with that of HFD group. Moreover, the hepatocytes of HFD rats showed a typical fatty liver morphology showing the presence of cytoplasmic lipid droplets, whereas administration of ATM attenuated the number and the size of lipid droplets. In the liver tissue of ATM administrated HFD group, the mRNA levels of SREBP-1c, $PPAR{\gamma}$, and FAS were decreased. Therefore, these results suggest that Acer tegmentosum extracts could have antioxidant activities and the hypolipidemic effects in liver tissue by its phenolic compounds.

  • This study was carried out to evaluate the effect of Cnidi rhizoma (CR) water extract on fat accumulation In fatted rats induced by the oral high fat administration for six weeks. To accomplish this evaluation, the serum and liver tissue have been examined for enzyme activity, cortisol and insulin level. The change of liver or tissue have been observed by the light microscope. GOT GPT and LDH activities were lower than the control group. Insulin and cortisol were higher than the control group, due to the fat accumulation. The liver of the control group observed by the tight microscope appeared to the fatty liver, but CR group showed some improvement of the fatty liver Based on the above results, it was shown that it is possible to improve fat accumulation induced by high fat dietary through using the oral administration of Cnidi rhizoma water extract.

  • Liver is the major organ to regulate the systemic glucose homeostasis and insulin resistance. Excess energy intake leads to triglyceride accumulation in adipose tissue first and subsequent accumulation in liver, resulting in obesity and type 2 diabetes. The representative pathological animal model for obesity associated insulin resistance is a high fat diet (HFD) fed mice model. Given the essential role of liver fat accumulation in developing systemic insulin resistance in obesity, I measured the liver triglyceride contents in HFD fed mice as a function of time. As such, in this report, I show the cause and effect relationship with regard to time during a HFD feeding between a variety of factors that are related to systemic insulin resistance including glucose intolerance, plasma insulin level and inflammatory gene expression in liver and adipose tissue.

  • Folate coenzymes are involved in one-carbon transfer reactions needed for the synthesis of nucleic acids, amino acids, and proteins which are very important for cell proliferation and differentiation. To investigate the effects of dietary folate content on plasma and tissue folate concentrations and on folate excretions in urine and feces, male Sprague-Dawley rats were raised for 4-10 weeks on semi-purified experimental diets containing 0mg, 2 mg, 8mg folate/kg diet. Folate concentrations were determined microbiologically using Lactobacillius casei (ATCC 7469). When compared to the folate adequate diet, the folate deficient diet decreased folate levels in plasma, liver and kidney , and the values were further decreased with experimental period. In rats reviving folate supplemented diets, plasma , liver and kidney folate adequate or supplemented diets, folate concentrations weer increased compared to animals on the folate adequate diet. In the folate adequate or supplemented diets, folate concentrations in the plasma and kidney were maintained at essentially the same level for 10 weeks . Folate concentrations in the liver, however, continued to increase with experimental period. Dietary folate intake seems to influence plasma and liver folate concentrations more than kidney folate concentrations. Folate excretions unrine and feces were significantly increased with dietary foalte intakes and experimental period. Folate excreted via urine was consideerably greater than that via feces. These resutls indicated that the foate supplemented diet improved plasma and tissue foalte status. Whether folate supplmentation improves foalte-dependent reactions remains to be researched.

  • We investigated the effect of a green seaweed Capsosiphon fulvescens extract (CFE) on the serum, liver tissue, and fecal cholesterol levels in rats. Male Sprague-Dawley rats (four weeks old) were given on of three diets for four weeks: basal, high cholesterol, and CFE, The total serum and liver tissue cholesterol levels in the CFE group were significantly decreased compared to those in the cholesterol group. The CFE group showed increased amounts of feces, total fecal bile acid and dietary fiber as compared to basal and cholesterol group. Hematoxylin and eosin staining revealed fat droplets in the livers of the rats in the cholesterol group; however, a decreased number of droplets was observed in the rats fed the CFE diet. Our results suggest that CFE supplementation may improve lipid metabolism, by controling serum and liver tissue cholesterol levels, and by increasing the total amounts of bile acid, dietary fiber and cholesterol excretion in feces.

  • Alcohol is a major risk factor for several diseases and excessive, long-term alcohol consumption are caues physical alteration-fatty liver, hepatitis, cirrhosis, breaking down, Wernicke-karsakoff's syndrome, weight loss, and poor immunity-in virtually all organ and tissue. This study was observed that liver, kidney, and stomach were altered in mouse by the effect of chronic alcohol administration. The mouse were sacrificed to obtain the tissue after mouse were orally injected with 25 % ethanol $18m{\ell}/kg/day$ for 120days. The tissue were stained by hematoxylin and eosin and then observed by light microscope. The results of this study were as follows : 1. The congestion was appeared in liver after 120days alcohol admistration. 2. The destruction of glomerulus were increased and the parietal cell of Bowman's capsule were swelled such as cuboidal cell after 120days alcohol administration. The congestion was appeared in alcohol administrated group. 3. The mucosa and gastric pit were destructed and the ulceration was appeared in stomach after 120days administration. The parietal cells and chief cells were damaged. Above results were shown that the tissue were damaged by chronic alcohol administration.
