Abstract

The half-time of equilibrium of Ca⁴⁵ with submaxillary gland was found to be 90 minutes in control rats and 30 minutes in pilocarpine treated rats, whereas the half-time of equilibrium for kidney was 2 minutes for both control and pilocarpine treated rats. The half-time for equilibration of equal amounts of calcium was 9 times longer in submaxillary gland than kidney in control rats and 6 times longer in piocarpine treated rats. The blood flow to submaxillary gland as determined by the fractional distribution of K⁴² was approximately 50% of kidney in control rats. Blood flow in both organs increased approximately 20% in piocarpine treated rats.
