本世纪60年代以来,不少学者观察到:在分次加温中,正常细胞与肿瘤细胞经过42.5℃以下的长时间加温,或在43～45℃急性加温后回到37℃常温,会在短时间内降低对热的敏感性,对再一次的致死温度的加温不敏感。这种观象称为热耐受(thermo-tolerance)。学者们认为热耐受是所有生物组织的普遍现象。近年来有关热耐受的研究在下列方面取得进展。热耐受的发生与衰退大量的实践资料表明:细胞的热耐受一般在初次加温后7～10小时出现,以后迅速增大,12～16小时达到最大,24小时以后开始衰退,48～72小时明显衰退,120～144小
Since the 60s of this century, many scholars have observed that in the sub-heating, the normal cells and tumor cells after 42.5 ℃ for a long time under heating, or after 43 ~ 45 ℃ acute warming back to 37 ℃ normal temperature, Will reduce the sensitivity to heat in a short time, insensitive to the warming of once again lethal temperature. This image is called thermo-tolerance. Scholars think that heat tolerance is a common phenomenon in all biological tissues. In recent years, studies on heat tolerance have made progress in the following aspects. The occurrence and decline of heat tolerance A lot of practical data show that: the heat tolerance of cells generally appear in the first 7 to 10 hours after heating, rapidly increased after 12 to 16 hours to reach the maximum, 24 hours after the start of decline, 48 ~ Significant decline 72 hours, 120 ~ 144 small
