| 1 | 厚朴酚对高脂饲料-STZ 诱导的糖尿病大鼠血糖血脂及肝脏氧化应激损伤的影响 (英文)显示文摘本文研究了厚朴酚对高脂饲料-链脲佐菌素诱导的2型糖尿病大鼠高血糖、高血脂、肝脏氧化应激和CYP2E1活性的影响。与糖尿病模型组相比,连续给予厚朴酚(25、50和100 mg·kg-1·d-1,灌胃)10周后,其血糖、血脂(TC、TG和LDL-C)及肝脏CYP2E1活性和MDA含量显著降低,口服糖耐量和肝脏抗氧化酶(CAT和GSH-Px)活性显著增加。研究结果不仅证明厚朴酚对高脂饲料-链脲佐菌素诱导的2型糖尿病大鼠的高血糖、高血脂、肝脏氧化应激损伤有明显治疗作用,而且厚朴酚对糖尿病大鼠肝脏CYP2E1活性的抑制作用可能是其拮抗糖尿病所致肝脏氧化损伤及胰岛素抵抗的重要机制之一。 | 王俊俊 赵容 梁继超 陈勇 | 2014 | 药学学报2014，49，4： | 11 |

| 3 | In vitro and in vivo antioxidative and hepatoprotective activity of aqueous extract of Cortex Dictamni显示文摘AIM To investigate the antioxidant and hepatoprotective effects of Cortex Dictamni aqueous extract(CDAE) in carbon tetrachloride(CCl4)-induced liver damage in rats.METHODS The in vitro antioxidant effect of CDAE was investigated using α,α-diphenyl-β-picrylhydrazyl(DPPH), 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid)(ABTS), β-carotene bleaching, reducing power, and thiobarbituric acid reactive substance assays. A linoleic acid system, including ferric thiocyanate(FTC) and thiobarbituric acid(TBA) assays, was used to evaluate the inhibition of lipid peroxidation. The in vivo hepatoprotective and antioxidant effects of CDAEagainst CCl4-induced liver damage were evaluated in Sprague-Dawley rats. Silymarin was used as a positive control. Liver damage was assessed by determining hepatic histopathology and liver marker enzymes in serum. Enzyme and non-enzyme antioxidant levels and lipid peroxide content were measured in the liver. Cytochrome P450 2E1(CYP2E1) protein expression was measured via immunohistochemical staining. Nuclear factor E2-related factor(Nrf2), heme oxygenase-1(HO-1), NAD(P)H quinine oxidoreductase 1(NQO1), and γ-glutamylcysteine synthetase catalytic subunit(γ-GCSc) protein expression was measured by Western blot.RESULTS Our results showed that CDAE exhibited a strong antioxidant activity in vitro. CDAE scavenged DPPH and ABTS radicals in a dose-dependent manner. CDAE inhibited lipid peroxidation with a lipid peroxide inhibition rate of 40.6% ± 5.2%. In the FTC and TBA assays, CDAE significantly inhibited lipid peroxidation(P < 0.01). In vivo histopathological studies indicated that CCl4-induced liver injury was alleviated following CDAE treatment in rats of both sexes. CDAE(160 and 320 mg/kg) significantly prevented CCl4-induced elevations of alkaline phosphatase, glutamate pyruvate transaminase, aspartate aminotransferase, and total bilirubin levels in rats of both sexes(P < 0.05, 0.01, or 0.001). Moreover, CDAE restored the decreased activities of hepatic antioxidant enzymes, including superoxide dismutase, catalase, and glutathione peroxidase, as well as non-enzyme antioxidant glutathione, which were induced by CCl4 treatment. CDAE significantly suppressed the up-regulation of CYP2E1 and promoted Nrf2, HO-1, NQO1, and γ-GCSc protein expression.CONCLUSION CDAE exhibits good antioxidant performance in vitro, with marked radical-scavenging and anti-lipid peroxidation activities. CDAE is effective in preventing CCl4-induced hepatic damage in rats of both sexes. The hepatoprotective activity of CDAE may be attributable to its antioxidant activity, which may involve Keap1-Nrf2-mediated antioxidant regulation. | Lin Li Yun-Feng Zhou Yan-Lin Li Li-Li Wang Hiderori Arai Yang Xu | 2017 | World Journal of Gastroenterology2017，23，16： | 6 |

| 5 | 茶多酚对乙醇所致原代肝细胞损伤的保护作用研究显示文摘目的研究乙醇对原代肝细胞的氧化损伤作用,同时探讨茶多酚对乙醇所致的原代肝细胞损伤模型的保护作用。方法分离小鼠原代肝细胞,直接以不同浓度乙醇作用于肝细胞,或以茶多酚预处理后再用乙醇作用于肝细胞,测定各组细胞存活率、抗氧化酶及丙氨酸氨基转移酶(ALT)活性的变化。结果随着乙醇浓度的增加,小鼠原代肝细胞存活率逐渐下降,抗氧化酶活性降低,转氨酶升高;而茶多酚的预处理对于乙醇所致的小鼠原代肝细胞损伤具有明显的保护作用,表现为相同乙醇浓度作用下,随茶多酚浓度的升高,细胞存活率逐渐升高,抗氧化酶活性增加,转氨酶下降,且差异有统计学意义(P<0.05)。结论乙醇可以诱导小鼠原代肝细胞的氧化损伤,而茶多酚对其氧化损伤具有明显的保护作用。 | 张栗 冉云 王玲 陈晨 张遵真 | 2009 | 营养学报2009，31，4： | 4 |
