Daily propranolol administration reduces pineal concretion formation in the Mongolian gerbil.
Daily afternoon injections of a beta-adrenergic blocking agent, propranolol, for 8 weeks inhibited the number of vacuoles and concretions formed in the gerbil pineal gland. The data suggest that sympathetic input to the pineal gland is necessary for the formation of pineal concretions.
