Adrenal lipid and plasma corticosterone depletion after 7,12-dimethylbenz(a)anthracene administration to the albino rat

Zusammenfassung Fluorometrische Messungen zeigten eine Abnahme von Plasmacorticosterone (CCS). Die Bedeutung dieser Resultate für theoretische Aspekte der Karzinogenese wird diskutiert.

Variations in cardiac noradrenaline content during sodium loading in hypertension prone and resistant rats

Summary The cardiac catecholamine content of Sabra rats and their 2 genetically derived substrains, hypertension prone and resistant rats, was studied by high pressure liquid chromatography and electrochemical detection. Both in the control period and after sodium and DOCA administration the cardiac noradrenaline level is higher in hypertension resistant rats than in Sabra rats, and also higher than in hypertension prone rats. This finding suggests that a reduction of the cardiac sympathetic nervous tone is involved in the genetic resistance to sodium.
