Ebselen is able to sim2 ulate the G lutathione hyperoxide enzymatic activity and to inhibit free radical loss leaded from high2intensity endurance motion obvi2 ously , perhaps because it have the enzymatic activity simulating G lutathione hyperoxide.

Results showed that L-THP possessed negative inotropic and negative chronotropic action, lowed left ventricular pressure and it's infinitesimal calculus, decreased heart output in per min., shorten 〓 and 〓 of action potential of ventricular papillary muscle of guinea pig and even the plate-phase of action potential disappeared in larger dose group , but prolonged 〓. we studied transmembrane transportation of 〓 after administering L-THP , L-THP not only depressed uptake and increased release of Ca 2+ in normal myocardium, but also it showed stronger inhibition in cell injured by ISO, and fully eliminated the effect of ISO increasing uptake and decreasing release of 〓. By detecting the 〓 content of ventricular single myocyte using fluorescent probe Fluo-3/AM, results correspond to that done above, L-THP decreased 〓 content inside of cell significantly. Using whole-cell mode, we observed the effect of L-THP on Ica in ventricular single cell, it was found that L-THP decreased Ica, the effect increased with increasing it's dose, and had voltage, frequency-dependency. Dose highly corelated to effect, corelative constant is 0.87. When washing cell with normal tyre's solution, Ica could recover, which proved the blocked action of L-THP on calcium channel once again. Meanwhile, L-THP reduced production of MDA in heart injured by ISO in dose-dependent manner, improved content of GSH-Px, in case tissue or cell free from free radical damage.

结果显示，该药物具有负性肌力和负性频率作用，降低左室压及其微分，终使每分心输出量减少；缩短豚鼠心室乳头肌动作电位时程的〓和APD〓，大剂量使动作电位平台消失，〓延长；同位素示踪法研究证实L-THP抑制〓摄取，促进〓释放，降低细胞内的〓含量；单通道水平的研究证实，L-THP减少豚鼠心室肌单细胞内向钙电流，且具有剂量，电压，频率依赖性，其作用易于洗脱，药物剂量与Ica也具有高度相关性（相关系数r为-0.87）；L-THP还可抑制ISO损伤心肌组织所致的丙二醛含量增加，增加谷胱甘肽过氧化物酶的量，使组织细胞免受损伤。L-THP阻断L-型〓通道，抑制〓的摄取，促进〓的释放，降低细胞内〓含量L-THP作用的离子基础。

In any cell equipped with the enzymes of the gamm-glutamyl cycle glutathione biosynthesis will be enhanced when the concentrationof the rate limiting substrate cysteine is increased intracellularly.

在含有谷氨酰循环酶的细胞内，当细胞内限速底物半胱氨酸浓度增高时，谷胱甘肽的生物合成提高。

in order to probe into whether glycine supplementation plays an adjusting role in sports performance and immune functions, the authors divided 30 mice randomly into an exhaustive exercising group (e1), glycine supplemented exhaustive exercising group (e2) and a normal resting control group, with 10 mice in each group, supplemented glycine to mice in group e2 and physiological saline to mice in the other two groups, let mice in groups e1 and e2 do an exhaustive swimming exercise 4 weeks later, applied the trace ch50 hemolysis method to analyze supplement activity, applied the mtt method to perform a quantitative analysis on the lymphopoiesis ability of spleen, and thus revealed the following findings: compared with mice in group e1, the time taken by mice in group e2 to swim to an exhausted state is significantly longer (p.05); total supplement activity in blood serum of mice in group e1 is significantly lower than the same of mice in group s (p＜0.01), and total supplement activity in blood serum of mice in group e2 is significantly higher than the same of mice in group e1 (p.01), but still significantly lower than the same of mice in group s (p.05); as observed from the test of the lymphopoiesis ability of spleen, the lymphopoiesis ability of spleen of mice in group e1 is significantly lower than the same of mice in group s, and the lymphopoiesis ability of spleen of mice in group e2 is significantly higher than the same of mice in group e1, but still significantly lower than the same of mice in group s.

四型肽精氨酸脱氨酶在类风湿性关节炎。。。以马来酸酐与氨水为原料热缩聚法合成。。。摘要：为探讨甘氨酸补充对运动能力及免疫功能是否具有调节作用，将30只小鼠随机分成力竭游泳运动组(e1)、甘氨酸补充后力竭游泳组(e2)和静息正常对照组，每组10只。在e2组补充甘氨酸，其余两组给予生理盐水，处理4周后，e1组和e2组均做力竭性游泳运动。采用微量ch50溶血法分析补体活性，采用mtt法定量分析脾脏淋巴细胞增殖能力。结果显示，与e1组比较，e2组游泳至力竭的时间显著延长(p＜0.01)。e1组血清总补体活性显著低于s组(p＜0.01)，e2组显著高于e1组(p.01)，但仍显著低于s组(p.05)。在脾脏淋巴细胞增殖试验中观察到，e1组显著低于s组，e2组显著高于e1组但仍显著低于s组。

Cows in the perinatal period were used in the experiment.Through clinical symptom and laboratory examination, they were divided into five groups that were healthy multiparity cows,healthy primiparity cows,cows with fatty liver disease, cows with ketosis and cows with rtention fetal membrance. We experimented blood of antepartum 15,8,1 day and postnatal 1,8,15,22 day,then assayed Thyroid hormone, thyroid-stimulating hormone, Iodine ,Selenium, GSH-Px in blood-serum. At last,we analysed data by statistical way .
