Relationships between Hypothalamic Catecholamines, Blood Pressure and Body Temperature in Spontaneously Hypertensive Rats

Abstract

Rectal temperature, catecholamine contents in the hypothalamus, and blood pressure were measured in spontaneously hypertensive rats (SHR) and normotensive Wistar-Kyoto rats (WKY).SHR had a significantly higher rectal temperature than WKY.Noradrenaline contents were lower in SHR than WKY.Noradrenaline was inversely correlated with the blood pressure e and body temperature in SHR.In subgroups of SHR, differences in values of the parameters mentioned above were also observed.
