Abstract
Experiments were performed at 2 time points in the 24-hr, cycle to determine whether isolated right atria of rats would vary in sensitivity, with a circadian rhythm, to 2 concentrations of acetylcholine. The beating rate of the atria decreased ore in response to the drug if the atria were isolated at 1100 than if isolated at 2300 hrs.This publication has 2 references indexed in Scilit:
