【摘要】 <正> 热对机体的影响,除引起与体温调节有关的生理机能紧张外,严重时可导致多系统的功能障碍。由于热致疾病的病理生理过程和临床表现不尽相同,因而导致热病在分类上的不一致。苏联学者将急性热病分为热射病与日射病两类,认为日射病是由于日光或热辐射强烈而持久地作用于无防护的头部而引起中枢神经系更多还原

【Abstract】 This report presents the results of model of experimental heat stroke in anaesthetised dogs. The experimental animals were divided into three groups: (1) heat stress over whole body; (2) heat radiation for head located; (3) heat stress over whole body heat radiation for head located. The observational indices Comprises: rectal temperature, tympanic temperature, breath, heart rate, ECG, and biochemical parameters. The results showed that the rectal temperature of all experimental animals exposed to heat raised with the increasing of the tympanic temperature. The most obvious. changes were seen in the group which exposed to the highest level of heat, but the differences among three groups showed no statistical significance, It suggested that the manifestations of physiological head strain and hyperthermia under the different conditions between whole body and local head heating be essen tially the same.更多还原
