The object of the present study was to clarify the neurotransmitter(s) controlling membrane responses to electrical field stimulation (EFS) in the circular smooth muscle cells of first-order branches of chicken anterior mesenteric artery. arabic 17 English 127

The neurotransmitter(s) that generate the inhibitory junctional potential (IJP) in the circular muscle of hamster distal colon and their mechanisms have not been elucidated. The aim of the present study, therefore, was to determine the contributing roles of the non-adrenergic, non-cholinergic (NANC) inhibitory transmitter(s) including nitric oxide (NO), adenosine 5′-triphosphate (ATP) and vasoactive intestinal polypeptide (VIP) in the generation of IJP in the hamster distal colon. For this purpose, the effects of the corresponding blockers of these putative NANC inhibitory mediators have been investigated using microelectrode technique. arabic 8 English 62

Electrical field stimulation (EFS) induces frequency-dependent contractions of the longitudinal muscle of isolated quail rectum which were sensitive to tetrodotoxin. The aim of the present study was to investigate whether purinergic neurons are implicated in the response to nerve stimulation. arabic 18 English 103
