发热是机体对入侵微生物的一种反应,是机体防御感染的组成部分。发热可限制或抑制传染因子的增殖,从某些方面增强宿主的抵抗力。本文主要讨论发热对机体免疫应答的影响。对温血动物来说,感染早期多形核白细胞(PMN)是抑制入侵微生物的重要细胞。温度对 PMN 功能影响的报道虽多,但结果很不一致。如温度升高对人 PMN 运动和吞噬金葡菌能力的影响,有人认为是起增强作 Fever is the body’s response to invading microorganisms and is part of the body’s defense against infection. Fever can limit or inhibit the proliferation of infectious agents, in some ways to enhance the host’s resistance. This article focuses on the impact of fever on the immune response. In warm-blooded animals, infection of early polymorphonuclear leukocytes (PMNs) is an important cell that invades microorganisms. The impact of temperature on PMN function has been reported for many times, but the results are very different. Such as temperature on the human PMN movement and phagocytosis of Staphylococcus aureus, some people think it is enhanced for
