      hypothermia
    Cooling strategies and transport theories for brain hypothermia resuscitation
          
    Under such adverse situations, the potential for cerebral protection through hypothermia has been intensively investigated in clinics by lowering brain temperature to restrain the cerebral oxygen demands.
          
    It is now clear that hypothermia would serve as the principal way for neurologic protection in a wide variety of emergency medicines, especially in cerebral damage, anoxia, circulatory arrest, respiratory occlusion, etc.
          
    Compared with the expanded trials in clinics, only very limited efforts were made to probe the engineering issues involved, which turns out to be a major obstacle for the successful operation of brain hypothermia resuscitation.
          
    Aiming to provide a complete overview of the brain hypothermia resuscitation, this article comprehensively summarizes the recent progresses made in theoretical, practical and experimental techniques in the area.

    A comparative observation about histological and histochemical study were made onthe preservating methods of local ischemic kidney of dogs.The methods of this exp-eriment were divided into five groups:A.Local hypothermia;B.Hypothermic perfu-sion solution 500ml,4℃,containing Procaine 450 mg and Heparin 100 mg,infusedinto renal artery;C.Hypothermic perfusion solution 500ml,4℃,containing 20% Ma-nniton 32ml,25% MgSO_4 0.36 ml,Heparin 100 ml,infused into renal artery;D.Localhypothermia and heparin 30 mg injected...

    本文对局部低温、低温平衡液附加其它药物灌注等五种保护缺血肾的方法,在13只狗的实验中进行了组织学及组织化学的初步观察和比较。实验结果表明:A 组(局部低温)、D 组(局部低温加肝素)及 E 组(局部常温)实验处理四小时内的不同间隔及停止处理后存活30~60天的取材标本中均显示了不可逆的组织学变化。琥珀酸脱氢酶、碱性磷酸酶、三磷酸腺苷酶均于实验处理1~2小时后开始减少,四小时后呈弱阳性或阴性反应,反应肾组织因缺血受损程度严重,说明这三种护肾措施对缺血肾保护作用不明显。B 组(低温灌注液加普鲁卡因及肝素灌注)实验处理时组织学及组织化学变化轻微,实验处理后60天所有变化基本恢复。C 组(低温灌注液加甘露醇、硫酸镁、ATP 及肝素灌注),实验处理时及处理后60天均未发现组织学及组织化学有异常变化,说明该组措施对缺血肾的保护效果较其余各组为佳。

    The functional changes of the unperfused canine livers under hypothermia preservation were studied with histochemistry method. The glucogen of the liver specimen was stained and observed in different temperature and different preservation periods. The results showed that the liver function was mildy damaged under 25℃ for 3 hours and 15℃ for 4 hours. The proper hypohermia was beneficial to the preservation.

    本文是对犬肝进行不灌洗低温保存(25℃、15℃)的系列研究之一。采用临床少用的组织化学方法对反映肝脏物质代谢功能的肝糖原进行动态观察,发现25℃离体保存不灌洗犬肝3小时变化轻微、功能良好;而15℃保存可延长到4小时,证明适当的低温能够使保存效果更好。

    In this study we observed the effect of hypothermia on pulmonary circulation and explored the role of sympothicus.Hy- pothermia induced reduction of cardiac output,and increase of pulmonary artery pressure.Pulmonary vascular resistance in- creased by 51.6%,but no change in pulmonary artery wedge pressure was noticed during hypothermia.The plasma level of norepinephrine increased markedly after blood temperature fell and there was no effect of hypothermia on arterial gas tensions. Prazosin could prevent the pulmonary hypertension induced by hypothermia and propranolol was no effect on pulomnary circu- lation during hypothermia.The results showed that hypothermia-induced pulmmary hypertension was caused by sympathicus, which greatly release norepinephrine and constrict pulmonary artery through α1 adrenoceptor.

    本文观察了低体温对肺循环的影响,并探讨了交感神经在其中的作用。低温时(33.5±0.19℃)动物心输出量下降,肺动脉压升高,肺血管阻力增加51.6%,肺嵌压变化不明显。体温下降时血浆去甲肾上腺素浓度明显升高,但不影响动脉血气值。派唑嗪可以阻止低温引起的肺动脉高压,心得安对低温时肺循环变化无明显影响。结果表明:低温所致肺动脉高压,是由于交感神经兴奋,去甲肾上腺素释放增加,通过α_1肾上腺素能受体,促使肺动脉收缩,导致肺动脉高压形成。
