Abstract

Stimulation of muscarinic cholinergic receptors with the highly potent and selective receptor agonist oxotremorine produced hypothermia in rats. Alaproclate, a purported selective serotonergic reuptake inhibitor, potentiated this response. Destruction of central presynaptic serotonergic terminals with the potent cytotoxin p-chloroamphetamine (PCA) failed to attenuate the hypothermic response to oxotremorine in alaproclate-pretreated animals. These results could be taken to suggest that alaproclate may act, at least in part, via a non-serotonergic mechanism to potentiate the oxotremorine-induced hypothermic response.

摘要

用高效且选择性的毒蕈碱胆碱能受体激动剂氧化震颤素刺激大鼠,可使其体温降低。声称是选择性5-羟色胺再摄取抑制剂的阿拉丙酯可增强这一反应。

用强效细胞毒素对氯苯丙胺(PCA)破坏中枢突触前5-羟色胺能终末,未能减弱阿拉丙酯预处理动物对氧化震颤素的低温反应。这些结果可表明,阿拉丙酯可能至少部分地通过非5-羟色胺能机制来增强氧化震颤素诱导的低温反应。
