COLLOID DROPLET FORMATION IN DOG THYROID IN VITRO

Abstract
Dibutyryl cyclic 3'',5''-AMP, like TSH [thyroid-stimulating hormone], causes the formation of pseudo-pods and intracellular colloid droplets when incubated with dog thyroid slices. Cyclic 3'',5''-AMP, acetylcholine, epinephrine, serotonin, puro-mycin, histamine and menadione were inactive.
