Abstract

Noradrenaline (10 microgram) injected into the lateral cerebral ventricle of guinea pigs aged 2 to 12 days produced a rapid increase in oxygen consumption and in colonic temperature at an ambient temperature of 30 degrees C. The increase was most pronounced in the youngest animals and decreased with advancing age, but was still significant at 12 days of age. Species differences and the role of ambient temperature in the responses are discussed.

摘要

给2至12日龄的豚鼠侧脑室注射去甲肾上腺素(10微克),在30摄氏度的环境温度下,其耗氧量和结肠温度迅速升高。这种升高在最年幼的动物中最为明显,并随着年龄的增长而降低,但在12日龄时仍很显著。文中讨论了物种差异以及环境温度在这些反应中的作用。
