In this study, we investigated the effects of green tea and Pueraria radix tea on the production of Apo B$_{100}$ in Hep G$_2$ liver cells and on the expression of the low density lipoprotein (LDL) receptor. Treatment with green tea resulted in a 60.7% decrease on the Apo B$_{100}$ concentration in Hep G$_2$ cells. Pueraria radix tea decreased Apo B$_{100}$ concentration by 63.5% in Hep G$_2$ cells. Green tea and Pueraria radix tea significantly decreased Apo B$_{100}$ concentration by 64.8% and 61.8%, respectively, in the media. Treatment of the cells with green tea and Pueraria radix tea also significantly decreased the intracellular total cholesterol, but total cholesterol concentrations in the media increased by 26.4% (green tea) and 23.6% (Pueraria radix tea) above that measured in the media of control cells. The addition of green tea and Pueraria radix to the media of the Hep Gz cells increased the LDL receptor binding activities by 84.1% and 79.4%, respectively.

This study was designed to investigate the effect of Pueraria radix extract on lipid metabolism in the rats fed high fat diet. Male sprague dawley rats were given 5% Pueraria radix extract and fed diet containing 20 weight % fat. The results obtained were summarized as follows. Serum ALT and AST activities were reduced by Pueraria radix extract. Levels of total lipid, total cholesterol and triglyceride in the serum were higher in the HF group than in the control, but showed no significant differences between control and HF Pue group. Liver total lipid, total cholesterol and triglyceride contents were increased by high fat diet, but were lower in the HF Pue group than in the HF group. Fat absorption rate was increased with high fat diet feeding and higher in the HF Pue group than in the HF group.

We have previously demonstrated that kudzu root extracts have a hypocholesterolemic effect on rats fed diets high in fat and cholesterol. To further elucidate the mechanism involved, in this study we investigated the effect of water extracts of kudzu root, Pueraria radix, on the production of apolipoprotein B$_{100}$ (APo B$_{100}$) in HepG$_2$ liver cells and secretion of apolipoprotein B$_{48}$ (Apo B$_{48}$) in Caco$_2$ cells. Human cell lines, HepG$_2$ liver cells and Caco$_2$ intestinal epithelial cells, were grown with various concentrations (0%, 0.5%, 1.0%, 1.5%, 2.0%) of water extracts of kudzu root in the media. The kudzu root extract decreased Apo B$_{100}$ production and secretion. Treatment of HeP G$_2$ cells with the kudzu root extract also significantly decreased the intracellular total and free cholesterol concentration, and also decreased esterified cholesterol but was only significant at the highest dose of 2%. Apo B$_{48}$ production, but not secretion, from enterocytes was lowered by the kudzu root extracts. This research provided evidence that the hypocholesterolemic properties of kudzu root may be a consequence of decreased production and secretion of Apo B$_{100}$ in the liver and Apo B$_{48}$ in the intestine.

Objectives Ethanol is a potent inhibitor of muscle protein synthesis. Muscle mass is regulated by the balance between rates of protein synthesis and protein breakdown. Both acute and chronic alcohol consumption inhibits synthesis to a greater extent than degradation. Protein synthesis is more intensely decreased in type II fibers than in type I fibers. Apoptosis has been shown to occur frequently in a variety of tissues in response to chronic alcohol feeding. Increased muscle fiber apoptosis has been shown in alcoholics with myopathy. Pueraria radix has been used for many disorders such as fevers, gastrointestinal disorders, muscle aches, allergies, respiratory problems, skin problems, high blood pressure, migraine headaches, lowering cholesterol and treating chronic alcoholism. We therefore tested the hypothesis that oral treatment with Pueraria radix could reduce the ethanol-induced muscle atrophy. Methods Young male Sprague-Dawley rats were orally given 25% ethanol (5 ml/kg, body weight) daily with Ethanol for 4 weeks. Normal group was similarly administrated with saline. The Rats of Pueraria radix treated group (EtOH+PR) were orally administrated Pueraria radix water extract, and rats of EtOH group were given with the vehicle only. After 4 week, the morphology of gastrocnemius and plantaris muscles were assessed by hematoxylin and eosin staining. The immunoreactivities of pre-apoptotic BAX and anti-apoptotic Bcl-2 proteins were also measured. Results The muscles from rats of EtOH group represented a significant reduction in average cross section area compared to Normal group. EtOH+PR group had increased fiber compared to the EtOH group. Moreover, to investigate the ethanol-induced muscular apoptosis, the immunohistochemical analysis of Bax and Bcl-2 was carried out. The treatment with Pueraria radix (EtOH+PR) significantly decreased BAX expression and increased Bcl-2 expression 4 weeks after ethanol administration when compared with Normal group. Conclusions These results suggest that Pueraria radix water extract has protective effects on chronic alcohol induced myopathy.

Effects of Galgeun(Pueraria radix) extracts on plasma and liver lipid composition, liver function and antioxidative capacity were investigated in rat fed high oxidized fat. Plasma total cholesterol and triglyceride concentration increased in the high oxidized fat groups, however these values showed a tendency to decrease in the Galgeun extracts groups. Plasma HDL-cholesterol concentration revealed a tendency to increase in Galgeun extracts groups. The concentration of liver total cholesterol showed no significantly different in all treatment groups, however liver triglyceride concentration showed a tendency to decrease in galgeun extracts groups. Thiobarbituric acid(TBARS) concentration in plasma and liver showed a tendency to decrease in galgeun extracts groups. The galgeun extracts samples have also decreased the plasma GOT and GPT activities, whereas they have increased the liver glutathione peroxidase, superoxide dismutase and catalase activity.

The radix of Pueraria thunbergiana BENTHAM (Leguminosae) is traditionally prescribed to attenuate the clinical manifestations of inner ear dysfunction and various clinical situations including fever, gastrointestinal disorders, skin problems, migraine headaches, lowering cholesterol and treating chronic alcoholism in Oriental Medicine. In the present study, we examined the effect of ethanol extract of P. thunbergiana radix (EPR) on cisplatin-mediated HEI-OC1 auditory cell death. In addition, to investingate the protection mechanism of EPR on free radicals. Treatment of EPR protected cells from cisplatin and reduced lipid peroxidation in a dose-dependent manner. Furthermore, EPR demonstrated significant scavenging activity against various free radicals, including superoxide radical, hydroxyl radical, hydrogen peroxide, and DPPH radical. These results indicate that EPR protects cisplatin-induced damages of HEI-OC1 cells through inhibition of lipid peroxidation and augmenting scavenging activities against free radials.

Objectives : This study was performed to investigate the effect of root extract of Pueraria thunbergiana Bentham (Puerariae Radix, PR) in diabetic mice as similar as emaciation-thirst disease in Oriental medicine. Methods : C57BL/6 mice were fed high fat (HF) and high sucrose (HS) for 8 weeks, and then administrated with 90 mg/kg body weight (bw) of streptozotocin (STZ) for induction of diabetes which is similar to the middle emaciation stage. After 5 days, blood glucose levels were measured, and selected the mice with ranges above $250mg/d{\ell}$. PR water extract was administrated orally once a day for 4 weeks with high fat and high sucrose. The levels of glucose, insulin, total cholesterol, triglyceride, ${\gamma}glutamyl$ transpeptidase (${\gamma}GTP$), glutamic oxaloacetic transaminase (GOT) and glutamate pyruvate transaminase (GPT) were analysed in the serum. Also, observed their histological changes by hematoxylin and eosin (H&E) of different organs, lung, heart, pancreas, stomach, liver, and kidney. Results : PR extract significantly decreased the levels of serum glucose and insulin in diabetic mice. PR extract significantly increased the levels of triglyceride, total cholesterol, GOT and GPT in diabetic mice. In H&E stain, PR extract inhibited the histopathological changes of lung (as a channel of the upper emaciation stage in the channel-tropism theory), pancreas (as a channel of the middle emaciation stage) and kidney (as a channel of the lower emaciation stage) in diabetic damage. Conclusions : PR extract has an anti-diabetic effect in HF/HS and low-dose STZ-induced diabetic mice. This result suggests that PR follows the channel-tropism theory in the emaciation-thirst disease through the protection of lung, pancreas and kidney.

A mechanism of hair cell damage caused by noise and ototoxic agents is mediated through generation of free radicals and reactive oxygen species(ROS). It is known that most of animals have defense systems of ROS that protect against ROS, and the cochlea of animals also has ROS defense system, which appear efficient in detoxifying ROS generated under normal condition. This system includes several antioxidant enzymes such as superoxide dismutase(SOD), catalase(CAT), glutathione peroxidase (GPX), and glutathione reductase(GR). The radix of Pueraria thunbergiana(P. thunbergiana) is traditionally prescribed to attenuate the clinical manifestation of inner ear dysfunction and various clinical situations including fevers, gastrointestinal disorders, skin problems, migraine headaches, lowering cholesterol, and treating chronic alcoholism in Oriental Medicine. In the present study, to investigate the protection mechanism of ${\beta}-sitosterol$ from P. thunbergiana on cisplatin cytotoxicity toward HEI-OC1, we measured the effects of ${\beta}-sitosterol$ on activities of SOD, CAT, GPX, and GR in cisplatin treated cells. SOD, CAT, GPX, and GR activities were significantly increased in the presence of 0.001-0.1 ${\mu}g/ml$ of ${\beta}-sitosterol$ compared to the control group. These results indicate that ${\beta}-sitosterol$ protects cisplatin-induced HEI-OC1 cell damage through increasing the antioxidant enzyme system such as SOD, CAT, GPX, and GR.
