[Activation of serotonin release in a perfused in situ segment of the rat jejunum]

The speed of the serotonin release into the opening of the perfused part of the small intestine of anesthetized rats increases considerably at adding into the solution of saccharose and protein hydrolyzates and also at increasing of medium acidity (pH 6,0). The block of vegetative ganglions and peripheral cholinoreactive structures reduces essentially speed of amine release.
