  • Objectives The purpose of this study was investigating effects of Jengjengamiyijin-tang (zhengzhuanjiaweierchentang) (JGYT) on lowering lipid, antioxidation and production of inflammatory mediators being used rats fed on high oxidized fat. Methods We divided fat Sprague-Dawley rats fed on high oxidized into 4 groups. Each of 8 rats was divided into a control group and experimental groups. We fed a control group of rats a basal diet and administered normal saline (100 mg/kg, 1 time/1 day) for 4 weeks. And We fed each experimental group of rats basal diet and administered an extract of JGYT extracts (100 mg/kg, 200 mg/kg, 300 mg/kg, 1 time/1 day) for 4 weeks. At the end of the experiment, the rats were sacrificed to determine their chemical composition. We measured lipid of plasma and liver, concentration of proinflammatory cytokines, antioxidative activity and plasma tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), plasma interleukin-6 (IL-6), Apo-B, Apo-E and Leptin gene expression. Results 1. Concentration of plasma FFA, LDL-cholesterol, plasma and liver total cholesterol showed a significant decrement in JGYT groups. However, concentration of plasma HDL-cholesterol showed a significant increment in JGYT groups. 2. Concentration of plasma and liver TG, TBARS showed a significant decrement in JGYT groups. However, concentration of liver GSH-Px, SOD and CAT showed a significant increment in JGYT groups. 3. Plasma GPT activity and concentration of plasma IL-6, TNF-${\alpha}$, NO, Ceruloplasmin, ${\alpha}1$-acid glycoprotein showed a significant decrement in JGYT groups. 4. In the analysis of RT-PCR, gene expression of Apo-B and Apo-E in the JGYT groups showed a low expression than that of control group. However, the gene expression of leptin showed no difference in all the treatment groups. 5. The ratio of leptin expression per ${\beta}$-actin expression showed no significant difference among all treatment groups. However, The ratio of Apo-B and Apo-E expression per ${\beta}$-actin expression showed a significant decrement in JGYT groups. Conclusions According to this study, extract of JGYT showed a positive effect in lowering lipid, antioxidation and control of inflammatory mediators production.

  • Although polysaccharide is believed to play an important role in the medicinal effect of Dendrobium chrysotoxum Lindl (DCL), its role as an antioxidant and in anti-hyperglycemic induction was not reported. In this study, polysaccharide with molecular weight of approximately 150 kDa, herein named DCLP, was isolated from the stem of DCL, and its antioxidative, hypoglycemic and immune stimulating effects were evaluated using various in vitro and in vivo assay systems. DCLP inhibited hydroxyl radicals ($^{\cdot}$OH)-mediated deoxyribose degradation by scavenging hydroxyl radicals directly as well as by chelating iron ions. DCLP also showed dose-dependent scavenging activity on superoxide anions ($O_2^{{\cdot}-}$) and offered significant protection (p < 0.001) against glucose oxidase-mediated cytotoxicity in Jurkat cells. DCLP had immune stimulating effects, as evidenced by the DCLP-mediated increases in the level of DNA synthesis, viability, and cytokine secretion in mouse lymphocytes. Moreover, oral administration of DCLP produced a significant reduction in blood glucose level in alloxan-induced diabetic mice. These findings suggest that DCLP has a potential utility in treating patients who require enhanced antioxidation, immune function and/or hypoglycemic activity.

  • Extraction of Sedum sarmentosum Bunge by super critical carbon dioxide was operated under $40-50^{\circ}C$and 200-250 atm, thus, yield of extraction was very low as 4 wt%. Rats were administrated with the extract orally once a day for succesive 6 days, followed by treatment with carbon tetrachloride ($CCl_4$) on the sixth day. The activities of aminotransferase, alkaline phosphatase, ${\gamma}$-glutamyl transpeptidase, lactate dehydrogenase and contents of triglyceride, total cholesterol in the extract-pretreated rats were decreased compared to the $CCl_4$controled rats, whereas content of HDL-cholesterol was increased. Especially content of hepatic malondialdehyde (MDA) and atherogenic index (AI) were decreased and HTR was increased in the extract-pretreated rats, and reduced peroxidative liver damage in the $CCl_4$-induced hepatotoxicity rats. In addition, activities of hepatic superoxide dismutase, catalase, glutathione peroxidase in the extract-pretreated rats were significantly decreased compared to the $CCl_4$ controled rats, but the content of glutathione was significantly increased. These results suggest that extract of Sedum sarmentosum Bunge has hepatoprotective effect in the $CCl_4$-intoxicated rats.

  • Basil is known to contain six types of polyphenols that engage in physiological activation; protocateuic acid, caffeic acid, chlorogenic acid, courmaric acid, rosmarinic acid and quercetin. In this study, the antioxidants in eight types of basil were evaluated. Specifically, the antioxidative activation of basil was evaluated based on the relationship between active oxygen scavenging (DPPH radical-scavenging), which was used as an index showing the content and functionality of the polyphenol compounds in basil, and $Fe^{2+}$/ascorbate (FTC) and 2-thiobarbituric acid (TBA). The total polyphenol content of the different types basil occurred in the following order: Dark-opal> Lettuce> Bush> Greek> Lemon> Sweet> Geno> Holy. The highest content Dark-opal was 173.3 mg, which was about three times greater than the lowest content Holy, which was 49.85 mg. In addition, DPPH radical-scavenging by Dark-opal 51%, which was the highest scavenging activity occurred in the folling order: Dark-opal> Lettuce> Bush> Greek> Lemon> Sweet> Geno> Holy. The antioxidative activation values measured using the FTC and TBA were the same as the value obtained using the DPPH method. Finally, the level of antioxidative activation measured using FTC, TBA and DPPH methods showed that the higher the content of polyphenol substance was, the stronger the antioxidative activation became.

  • Taurine is an abundant, ${\beta}-amino$ acid with diverse cytoprotective activity. In some species, taurine is an essential nutrient but in man it is considered a semi-essential nutrient, although cells lacking taurine show major pathology. These findings have spurred interest in the potential use of taurine as a therapeutic agent. The discovery that taurine is an effective therapy against congestive heart failure led to the study of taurine as a therapeutic agent against other disease conditions. Today, taurine has been approved for the treatment of congestive heart failure in Japan and shows promise in the treatment of several other diseases. The present review summarizes studies supporting a role of taurine in the treatment of diseases of muscle, the central nervous system, and the cardiovascular system. In addition, taurine is extremely effective in the treatment of the mitochondrial disease, mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS), and offers a new approach for the treatment of metabolic diseases, such as diabetes, and inflammatory diseases, such as arthritis. The review also addresses the functions of taurine (regulation of antioxidation, energy metabolism, gene expression, ER stress, neuromodulation, quality control and calcium homeostasis) underlying these therapeutic actions.
