氧中毒

Aim: To observe the changes of the expression of NSE, COX-2 in cerebral tissue in rats withgas toxicosis of acute Anchovy degeneration, and to discuss its molecular mechanism.

目的：观察鱼腐败气体中毒后大鼠脑组织神经元特异性烯醇化酶、环氧合酶(COX-2)表达的变化，探讨中毒的分子机制。

The mechanism of carbon monoxide poisoning are: access to it soon after the alveolar and hemoglobin have a strong affinity to enable the formation of hemoglobin carboxyhemoglobin, to stop the combination of hemoglobin and oxygen.

一氧化碳的中毒机理是：它进入肺泡后很快会和血红蛋白产生很强的亲合力，使血红蛋白形成碳氧血红蛋白，阻止氧和血红蛋白的结合。

Once the higher the concentration of carboxyhemoglobin, hemoglobin to carry oxygen to the tissues of the function will be hindered, and the impact of the shortage of oxygen supply the most sensitive central nervous system and cardiac function, caused by hypoxia, which lead to poisoning symptoms .

一旦碳氧血红蛋白浓度升高，血红蛋白向机体组织运载氧的功能就会受到阻碍，进而影响对供氧不足最为敏感的中枢神经和心肌功能，造成组织缺氧，从而使人产生中毒症状。

All accord with DMS of professional sex acute toxic diagnostic standard [2] , spend gently among them, in spend each 4. Classics mouth conduit gives to suck oxygen and heart report custody namely after 1.3 cure and result are admitted to hospital 8 times, diagnose hind all applies antibiotic to prevent infection all over, pulverization is inspiratory eliminate laryngeal oedema, and support treatment to disease, strengthen a foundation to nurse. Degree of saturation of 4 pulse oxygen (SpO2)75%~85%, 2 routine are tracheal dissection, epispastic gas secretion of appearance of the bubble inside the canal, afterwards grants to breathe out...

均符合职业性急性DMS中毒诊断标准[2]，其中轻度、中度各4例。1.3治疗及结果8例入院后即给予经口导管吸氧及心电监护，确诊后均全身应用抗生素预防感染，雾化吸入消除喉头水肿，以及对症支持治疗，加强基础护理。4例脉搏氧饱和度(SpO2)75%~85%，2例行气管切开，吸出气管内泡沫样分泌物，继予呼。。。

Our study showed that in the early stage of MODS RAL with or without hypoxemia might be present,and later or,there might be MA or even triple ABD.In order to detect and correct the primary disorders as early as possible,it is important to keep the balance of hydrolyte.

严重创伤后并发MODS患者早期多为呼吸性碱中毒，同时伴有低氧血症，随着病情的进展，在呼吸性碱中毒的基础上并发代谢性酸中毒，严重者可发生三重型酸碱平衡紊乱。

Methods Based on comprehensive trentment, the consciousness ,respiration and blood oxygen saturation of the patients are monitored closely, When the patients show the symptoms of heavy tetrodontoxism Such as coma, quadriplegia, respiratory muscle paralysis and blood oxygen saturation beginning to go down, they receive effective mechanical ventilation with artificial airway by endotracheal intubating in time.

综合治疗的基础上，密切监测河豚鱼中毒患者的神志、呼吸及经皮血氧饱和度，当患者出现重度中毒症状，如昏迷、四肢瘫痪、呼吸麻痹，监测经皮血氧饱和度下降时，及时气管插管、机械通气抢救。

paraquat is one kind of weedicide that comprehensive used all over the world ,for its little pollute to the environ accept a generally welcome .but the poisoning of paraquat have become a more and more severe problem,especially in developing county.the paraquat have a hypso-toxicity to human ,its mortality is 85%~95%.it show a multisystem injury to human body but the most serious injury of the paraqat to the viscera is lung .the mechanism of damnification is the great deal of super-oxygen ion procreant by paraquat in lung .at present the best technique to the diagonose of the paraquat poisoning to lung injury is ct.

百草枯是目前全世界范围内应用最广泛的除草剂，以其对环境的低污染性而受到广泛欢迎，但是百草枯中毒也随之成为一个越来越严重的题目，尤其是在发展中国家。百草枯对人体呈高毒性，死亡率约为85%~95%。百草枯中毒表现为多系统损伤，但是对人体脏器最主要的损伤是肺损伤，损伤机制主要为百草枯在肺组织内产生的大量超氧离子。目前对百草枯中毒致肺损伤的诊断最佳的方式是CT。

"There are four types: hypoxemic, from low blood oxygen content (e.g., in altitude sickness); anemic, from low blood oxygen-carrying capacity (e.g., in carbon monoxide poison ing);"

有四种类型：一、低氧血型，即血液里含氧量低，如高原病；二、贫血型，血液携氧能力低，如一氧化碳中毒

The results showed 3 types of aluminum compound prepared in this paper all had good poison protection effectiveness on such impurities as stannous chloride,lead oxide,sodium hydrogen sulfate,and so on.Moreover,the mechanism of the poison of catalyst was also discussed.

结果表明，合成的3种防中毒剂即防－1、防－2(主要成分为乙酰丙酮合铝)及防－3(主要成分为二乙酰丙酮基异丙氧基铝)对二月桂酸二丁基锡、氯化亚锡、二正丁胺、硫脲、氧化铅及硫酸氢钠等杂质均有较好的防中毒作用；不同防中毒剂对不同杂质的防中毒作用有一定的选择性。

Choice 36 carbon monoxide poisoning sufferer,application BIPAP breath machine assistance ventilate treatment,and with through nose pipe give oxygen treatment carry on comparison.

选择36例一氧化碳中毒患者，应用BIPAP呼吸机辅助通气治疗，并与经鼻导管给氧治疗者进行比较。结果：治疗组治疗后4h PaO2及。。目的：探讨采用经面罩正压机械通气给氧治疗急性重度一氧化碳中毒患者的作用。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
