Morphological relationship between serotonergic neurons and nitrergic neurons for electrolytes secretion in the submucous plexus of the guinea pig distal colon
M. Kadowaki et al., Morphological relationship between serotonergic neurons and nitrergic neurons for electrolytes secretion in the submucous plexus of the guinea pig distal colon, BRAIN RES, 831(1-2), 1999, pp. 288-291
In the submucous plexus, double immunocytochemistry revealed that nitric ox
ide synthase (NOS)-immunoreactivity was found in both numerous nerve fibers
and some nerve cell bodies, while 5-hydroxytryptamine (5-HT)-immunoreactiv
ity was limited to many nerve fibers, but not any nerve cell bodies. About
30% of the total NOS positive neurons (978) had close or some contact with
5-HT positive nerve fiber, suggesting that NO may participate in the 5-HT-e
voked chloride secretion. (C) 1999 Elsevier Science B.V. All rights reserve
