Summary
The influence of certain drugs on the ultrastructure of rabbit pinealocytes was studied. The results obtained after administration of p-chlorophenylalanine and p-chloroamphetamine support the hypothesis proposed earlier that the smooth endoplasmic reticulum in the light pinealocytes is involved in indoleamine synthesis.
The administration of either one of the sympatholytic agents, 6-hydroxydopamine or α-methyl-p-tyrosine, induced typical fine structural changes corresponding to those observed after surgical sympathectomy.
