Summary In this experiment we studied the role of excitatory and inhibitory neurotransmissions in the ascending reflex pathways in isolated rat colon. Partitioned organ bath, electrical field stimulation (EFS), drugs and isolated preparations were us

We evaluated the motor responses in recto-anal preparations obtained from rats, in terms of the excitation displayed by modules of nerve networks and descending distally directed pathways, when subjected to the mechanographic on-line technique, a par

The recto-anal region is innervated by extrinsic and intrinsic nerves and a number of neuropeptides including substance P (SP) have been suggested to participate in the regulation of intestinal movements. We examined the age-related changes in the di

Since the distal part of the intestine is targeted by a wide range of pathogens, the motility of the recto-anal region has been the object of many experimental and clinical observations. In this study, we investigated descending motor responses in th

The effects of the peptide transmitter neurotensin (NT) on the release of acetylcholine (ACh), gamma-aminobutyric acid (GABA), glutamate (Glu), aspartate (Asp), and taurine from the prefrontal cortex (PFC) of freely moving rats were studied by transv

1. The interaction of nitric oxide and ATP in the non-adrenergic, non-cholinergic (NANC) motor responses and the presence of NADPH-diaphorase and quinacrine-positive myenteric neurones were studied on guinea-pig ileum using mechanographic, histochemi

1. The possible contribution of the nonadrenergic noncholinergic (NANC) transmitters nitric oxide (NO) and substance P (SP) to the contractility of guinea pig isolated ileum was studied by the responses of the longitudinal muscle to electrical field

Male Wistar rats were exposed to Pb2+ or Zn2+ and to Pb2+ + Zn2+, receiving Pb(CH3COO)2 or/and ZnSO4 with drinking water for 30 days. Cumulative concentration-effect curves for carbachol were obtained in ileum and trachea isolated from control and he

1. Effects of the fragments H-Gly-Phe-OH, H-Gly-Phe-NH 2 or H-Gly-Phe-OMe on the electrically stimulated cholinergic contractions of the longitudinal layer in isolated guinea pig ileum and on the Morphine-, Met-enkephalin- or Leu-enkephalin-induced i
