Abstract

In control and capsaicin-treated (300 mg/kg) rats tail skin vasodilatation was studied while the body temperature was raised to 38 degrees C, 39 degrees C or 40 degrees C and held at these levels. In the capsaicin-treated rats, at 38 degrees C vasodilatation was weaker than in the controls but at temperatures of 39 degrees C and 40 degrees C a delayed increase in tail vasodilatation occurred to the level observed in the controls. It is concluded that the threshold of vasodilatation response to heat is elevated after capsaicin treatment.

辣椒素治疗后大鼠热调节性血管舒张阈值升高。
在对照组和辣椒素(300 mg/kg)处理的大鼠中,当体温升高到38℃、39℃和40℃并保持在这些水平时,研究了尾部皮肤血管舒张。在辣椒素处理的大鼠中,在38摄氏度时血管扩张比对照组弱,但在39摄氏度和40摄氏度的温度下,尾部血管扩张的延迟增加出现在对照组中观察到的水平。结论:辣椒素处理后,热血管舒张反应阈值升高。
