Abstract

Thermoregulatory responses after treatment with nitric oxide (NO) donor, sodium nitroprusside (SNP-3 mg/kg/h), or NO synthase inhibitor, NG-nitro-L-arginine methylester (L-NAME-100 mg/kg) were investigated in febrile rabbits (lipopolysaccharide E. coli-1 meg/kg). Pretreatment with SNP attenuated pyrogen fever as well as metabolic rate. L-NAME also inhibited postpyrogen increases in metabolism; however, this effect did not lead to antipyresis.

摘要

在发热兔(大肠杆菌脂多糖-1毫克/千克)中研究了用一氧化氮(NO)供体硝普钠(SNP-3毫克/千克/小时)或NO合酶抑制剂NG-硝基-L-精氨酸甲酯(L-NAME-100毫克/千克)治疗后的体温调节反应。用SNP预处理可减轻致热原性发热以及代谢率。L-NAME也抑制了热原后代谢的增加;然而,这种作用并未导致解热。
