Adrenaline-Forming Enzyme in Brainstem: Elevation in Genetic and Experimental Hypertension

The adrenaline-forming enzyme (phenylethanolamine N-methyltransferase) was elevated in the A$_{1}$ and A$_{2}$ regions of the brainstem of 4-week-old spontaneously (genetic) hypertensive rats and in the A$_{1}$ region of adult experimentally (deoxycorticosterone acetate and sodium chloride) hyperten...

description The adrenaline-forming enzyme (phenylethanolamine N-methyltransferase) was elevated in the A$_{1}$ and A$_{2}$ regions of the brainstem of 4-week-old spontaneously (genetic) hypertensive rats and in the A$_{1}$ region of adult experimentally (deoxycorticosterone acetate and sodium chloride) hypertensive rats. The administration of a phenylethanolamine N-methyltransferase inhibitor to experimentally hypertensive animals caused a reduction of the elevated blood pressure to normal values. These results implicate adrenaline-containing neurons in the brainstem in the development of hypertension.
