D. Evequoz et al., MECHANISMS OF THE PRESSOR-RESPONSE TO INTRAVENOUS THYROTROPIN-RELEASING-HORMONE IN THE RAT, Clinical and experimental pharmacology and physiology, 21(2), 1994, pp. 93-100
1. The purpose of this study was to examine the contribution of the sy
mpatho-adrenomedullary system to the blood pressure response to an int
ravenous bolus of thyrotropin-releasing hormone (TRH) in conscious med
ullectomized and sham-operated rats. 2. The peak presser effect of 0.5
mg TRH was significantly increased in rats having no adrenal medulla
(+24.2+/-1.6 mmHg, mean+/-s.e.m., P<0.01) as compared to sham-operated
animals (+12.2+/-3.0 mmHg).
