Abstract
Summary
The concentration of serotonin in the female chicken intestine (10.79 μg/g wet tissue) was significantly higher than in the male (7.98 μg/g).
The release of serotonin from an isolated perfused intestine was studied. The intestine continually releases serotonin at the rate of 10 ng per g/min. A number of substances, including glycine, epinephrine, and acetyl-choline, caused a significant release of serotonin, with acetylcholine having the greatest effect. Histamine or electrical stimulation did not affect the release of serotonin.
