[Effects of heat, noise, and their combination on plasma atrial natriuretic peptides, cardiodilatin, endogenous digitalis like substance, angiotensin II and endothelin in rats].
Plasma contents of atrial natriuretic peptides (ANP), cardiodilatin (CDD), endogenous digitalis like substance (EDLS), angiotensin II (A II) and endothelin (ET) were determined in rats following exposure to high temperature, noise and a combination of the two. It was found that plasma content of ANP after heat exposure decreased significantly, CDD and A II content after heat or noise exposure increased obviously, ET content decreased significantly after exposure to combined factors. ANP and CDD have the same physiological function and changes. ANP, CDD and A II observed in the present study were considered to be compensatory responses. It is harmful if exposure to high temperature or noise lasts for a long time.
