Salivatory responses to classical and nontraditional parasympatholytic agents in human subjects: critical comments.

Both classical (atropine, scopolamine) and nontraditional (pirenzepine, telenzepine) cholinolytic agents themselves cause no salivation in human subjects. Ordinarily, they block salivation caused by pilocarpine. Conversely, they all stimulate intense salivatory response in the chronically denervated human parotid gland. The author presents critical comments on the concept that cholinolytic agents cause salivation by suppression of the mechanism of presynaptic autoinhibition. An alternative explanation of the initial cholinomimetic effect of cholinolytic agents is suggested.

The influence of some sympatholytic, parasympatholytic and serotonin-synthesis-inhibiting agents on the ultrastructure of the rabbit pineal organ.

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 alpha-methyl-p-tyrosine, induced typical fine structural changes corresponding to those observed after surgical sympathectomy.
