background: n-acetylcysteine (nac) has been indicated against experimental seizures, but with relatively inconclusive results. this study was undertaken to evaluate whether nac exerts a dose-dependent anticonvulsant effect and to determine nac safe therapeutic dose range and its muscle-relaxant activity in both acute and chronic uses. methods: following intraperitoneal (i.p.) administration of ...
Unlike its effects on the rest of the GI tract, the effects of pituitary adenylate cyclase-activating peptide (PACAP) on the internal anal sphincter (IAS) are not known. We examined the actions of PACAP-38 (here PACAP) and PACAP-27 on the basal IAS tone of circular smooth muscle strips before and after the administration of different neurohumoral antagonists. PACAP caused a concentration-depend...
AIM In endothelium-denuded arteries, the nitric oxide (NO) donor S-nitrosoglutathione (GSNO) induced a persistent hypo-reactivity to vasoconstrictors, and low-molecular weight thiols such as N-acetyl cysteine (NAC) produced a relaxant effect. These effects were attributed to the formation of vascular NO stores. In arteries with a functional endothelium, such long-lasting effects on arterial ton...
The effect of beta-adrenoceptor activation on levcromakalim-induced relaxation was investigated in myograph-mounted rat mesenteric arteries. The nonselective beta-adrenoceptor agonist isoproterenol (at a concentration causing approximately 30% relaxation of methoxamine-induced tone) potentiated relaxation to levcromakalim; higher concentrations exerted no additional effect. The modulatory and r...
