Search for: [Abstract = "d vagotomized rats. Pharmacologic sympathectomy was performed with 6\-hydroxydopamine and subdiaphragmatic vagotomy was performed during gastric fistula implantation. In control group after vasopressin induced gastroparesis, carbachol was administered and recording continued. All surgical procedures were performed in surgical anaesthesia. Gastric slow wave frequency was recorded via previously implanted on gastric antrum silver electrodes and tunnelled on the neck of the rat. Cuff electrode was placed on isolated afferent and efferent cut end of the cervical left vagus nerve and vagal afferent and efferent recordings were performed in anaesthetised fasted control, pretreated with L\-NNA and indometacine and after vasopressin analogue \(AVP\) administration in every group of rats. Results\: AVP administration caused transient increase of basal tonic contraction of the stomach and suppressed occurrence of phasic contractions. Sympathectomy, vagotomy, indometacin and nifedipine did not prevented occurrence of transient AVP\-induced gastroparesis. Administration of cholinomimetic\- carbachol reversed AVP\-induced gastroparesis. Vagal afferent and efferent activity did not changed significantly under influence of AVP among group of rats pretreated with L\-NNA and indometacine. In summary mechanism of vasopressin induced gastroparesis is not dependent on nitric oxide and prostaglandins and is"]
