T was found by Issaacs in 1957 when he made use of chick embryo chorioallantois to study interference phenomenons of flu virus.

ssacs(1961)认为，IFN是机体对异种核酸的反应性产物，如同机体对异种蛋白产生抗体一样。

Result revealed :Long time resistance training could increase the level of NO, iNOS and TNF-a in serum of rat, which had correctitude correlations in diversification . The level of NO, iNOS and TNF-a in serum of untrained rat had a markedly raise after one time exhausting exercise, which was likely to have relationto the answer of organism to exercise. During exercise, the raise of level of NO, iNOS and TNF-a in serum of untrained rat could promote blood circle ,transportation of substance and energy, level of immunity and was seasoned with other level of cytokines .

结果显示，大鼠长期有氧训练能够提高其血清中NO、iNOS和TNF一a水平，三者变化呈现正相关；未训练大鼠在一次性运动至力竭时，NO、NOS和TNF一a水平显著上升，这可能与一次性运动相适应机体生理应激有关，TN下一a、NO、iNOS含量/活性水平显著提高，促进血液循环，提高物质能量的运输，优化免疫水平以及与机体内其他细胞因子水平相适应。

Based on ANSYS software,this paper built up a precise cylinder block contact model for diesel engine.

以柴油机机体为研究对象，利用ANSYS软件构建了精确的机体有限元接触模型。

The aim of this study was an evaluation of the influence of HiLoon aerobic performance and its physical effects. Elite swimmers、 collegestudents major in physical education and rats were exposed to simulatedaltitude in a decompression chamber and the followings were investigated:(1) erythropoiesis and erythropoietin,(2)maximal oxygen uptake,(3)body weight and body composition,(4)serum parameters of metabolism andhormone,(5)erythropoietin gene expression in kidney and vascularendothelium growth factor gene expression in heart.1 Effects of simulated "living high-training low" on aerobic performancein elite swimmersFourteen swimmers (10 men, 4 women) from Shandong swimming team weredivided into two groups: experimental group (living high-training low,n=8,6men,2women),living at a simulated altitude of 2,800m for 13 to 14 hours per day for 3weeks in a decompression chamber and training at sea level; control group(living low-training low, n=6,4 men,2 women),living and training at sea level.

为系统探讨高住低练对机体有氧能力的影响及其机制，本研究利用低压舱来模拟高原气压条件，分别以优秀游泳运动员、体育专业大学生和大鼠为实验对象，从以下几个方面来初步探讨模拟高住低练对机体的影响：(1)红细胞生成和EPO，(2)最大摄氧量和无氧阈，(3)体重和身体成分，(4)血清物质代谢指标及激素水平，(5)大鼠肾脏EPO和心脏VEGF基因表达。1 模拟高住低练对优秀游泳运动员有氧能力的影响 14名山东省游泳队运动员(男10人，女4人)，随机分为两组：实验组(模拟高住低练组，男6，女2)和对照组(低住低练组，男4，女2)。

Superoxide dismutases family are thought to be one of the first lines of antioxidant defense and are highly efficient in protecting cells and tissues against oxidative stress by catalyzing the dismutation of superoxide radicals to form hydrogen peroxide and molecular oxygen.

但由于活性氧分子反应的非特异性，它们也会破坏宿主机体细胞内的功能蛋白分子、不饱和脂肪酸分子和核酸等，对细胞造成严重的伤害，进而导致机体生理机能的损伤和免疫系统的破坏。

Superoxide dismutase (EC 1.15.1.1;SOD) is a metal-containing enzyme that widely exist in organisms. It catalyzes the dismutation of superoxide free radical and produces hydrogen peroxide and oxygen.It plays an important role in protecting the plasmalemma from the reactive oxygen species.A recombinant plasmid pPICZA-sodM18 was constructed and after its linearization was transferred into chromosome of Pichia pastoris GS115 by electroporation.

超氧化物歧化酶(Superoxide dismutase；EC 1.15.1.1；SOD)是广泛存在于生物体内的金属酶，是机体内唯一以超氧阴离子自由基(O_2~-)为底物的酶，它能专一地催化O_2~-的歧化反应，生成过氧化氢和氧气，能有效的抵御氧自由基和其他氧化物自由基对细胞质膜的毒性，对机体防御氧化损伤起着十分重要的作用。

The analysis of HRV could distinguish the effects of diverse excitant. It was a sensitivity index when discussing the effect of music.

心率变异性分析能够区分机体对不同刺激的反映，是探讨音乐对机体作用的敏感指标。

Water buffaloes, goats and rats were selected to study the change of antioxidant function and to determine the change of eicosanoids and other immuno-factor during experimental fascioliasis in order to explain the role of free radical in the pathogentic course of fascioliasis.

本实验以水牛、山羊和大鼠为模型，研究肝片吸虫感染后机体抗氧化功能的变化，同时检测了山羊和大鼠血浆中花生四烯酸代谢物的变化以及部分其他因子，综合分析各因素在肝片吸虫感染中的作用，着重研究了机体自由基在肝片吸虫发病过程中的作用。
