查询词典 glutathione

In this study, we investigate the heat-induced inhibition of drug-metabolizing enzyme activity in mice fed with freeze-dried, heated freeze-dried or half amount autolyzed freeze-dried Brussels sprouts powder. 0.5% ethoxyquin diet was fed to another group of mice as a positive control. The study mice, four per group, were fed a diet consisting of 20% Brussels sprouts for 7 days. Each group had its own pair-fed group. We found significantly greater inductions of glutathione S- transferase, quinine reductase, and phase Ⅱ drug-metabolizing enzyme activities in groups fed within freeze-dried and heated freeze-dried Brussels sprouts than their pair-fed groups. These findings indicate that intestinal microflora still can hydrolyze glucosinolates without plant myrosinase activity, though the alteration of cytochrome- P-450 1A (CYP1A, a phase Ⅰ drug-metabolizing enzyme) induction was only 1.4-fold.

本实验欲进一步探討加热处理之抱子甘蓝对phase Ⅰ与phase Ⅱ解毒酵素活性之影响差异，实验分三组，抱子甘蓝(1)冷冻乾燥组（glucosinolate未裂解）(2)加热冷冻乾燥组(3)半量之裂解冷冻乾燥组（glucosinolate已裂解），(4)and 0.5% ethoxyquin diet was used as a positive control以2%重量混合成饲料，餵以小白鼠（4只／组）7天，结果发现，在第(2)组小白鼠GST phase Ⅱ酵素）活性显著上升，显示在植物裂解酵素不存在之状况下，肠胃道之微生物仍可促进裂解反应，但由CYP1A活性增加不显著（仅1.4倍）看来，根据定义：单独phase Ⅱ酵素活性增加，为monofunctional induction/inducer，可加速致癌物之代谢。

Methods : The levels of fasting blood glucose and fast plasma insulin, the activities of superoxide dismutase and glutathione peroxidase and level of lipid peroxidate were measured in the pancreas, heart and liver of normal and streptozotocin-induced diabetes-prone mice exposed to multiple stressors for 6 weeks. Results : The FBG level in STZ mice was elevated by stress, while the FINS level was not increased.

observing the influence on the weight of rats and the content of peroxidize lipid degradation product-malonaldehyde in blood and the activity of superoxide dismutase and glutathione peroxidase in blood.

方法采用观察对大鼠体重、血中过氧化脂质降解产物丙二醛含量及血中超氧化物歧化酶、谷胱甘肽过氧化物酶活力的影响。

The synergism ratios of piperonyl butoxide to alpha-cypermethrin in these three strains were similar(about 20-fold), which suggested metabolic detoxification probably confers about 20-fold inherent resistance in the B-type whitefly, as PBO is a mixed function oxygenase and esterase inhibitor and glutathione S-transferase is not affinity to resistance in B. tabaci. The synergism ratio of triphenyl phosphate to alpha-cypermethrin in the NJ strain was 12-fold, which implied the synergism of PBO in the B-type whitefly is mainly due to inhibiting esterase activity.

增效试验表明PBO对这三个品系的增效作用均为20倍左右，因为在烟粉虱中PBO即是多功能氧化酶抑制剂，也是酯酶抑制剂，而谷胱甘肽S-转移酶与抗性无关，因此推断代谢酶在B型烟粉虱对高效氯氰菊酯的抗性发展中起到的相对作用可能为20倍左右，而且这种抗性是B型烟粉虱天生的；TPP对NJ品系的增效作用为12倍，说明PBO增效作用主要是由于抑制酯酶而引起的，即代谢抗性大部分由酯酶所贡献。

The effects of capsaicin on glutathione S-transferase and Na(superscript +)-K(superscript +)-ATPase of Plutella xylostella were tested with conventional methods in laboratory.

采用常规生化方法测定了辣椒碱对小菜蛾体内谷胱甘肽S-转移酶和Na-K-ATP酶活性的影响。

The changed physiological parameters in the body of ladybird in every season caused these differences. The body weight including fresh and dry weight, content of fat and glycogen, activities of glutathione S-transferase in the body of H. axyridis all decreased gradually in overwintering. All these indices began to recircle after hibernation and would be up to the optimum status when they entered dormancy.

造成这种差异的原因是不同时期异色瓢虫体内的一些生理指标不一样，在越冬期异色瓢虫体重、脂肪和总糖含量逐渐降低，谷胱甘肽S-转移酶的活性也逐渐下降，出蛰后各项指标又开始回升，直至进入越冬时达到最佳状态。
