| pubmed-article:10480659 | pubmed:abstractText | Nitrated nonivamide (NVANO)-induced triad hypotension, and biphasic bradycardia at 0.25-1.0 mg/kg (IV) was inhibited by capsazepine (1.0 mg/kg, IV), atropine (1.0 mg/kg, IV), and vagotomy in rats. NVANO also elicited a hypotensive spinal reflex at 5.0 mg/kg (IA). In the isolated rat vagus, NVANO (10.0-100.0 microM) revealed a sensory C-spike inhibition and membrane depolarization. NVANO (5.0 microM)-induced calcium influx in the isolated rat dorsal root ganglion cells (DRGs) was diminished by capsazepine (10.0 microM). In the isolated guinea pig atria, NVANO (1.0-50.0 microM)-induced positive inotropic and chronotropic activities were antagonized by capsazepine (1.0-10.0 microM) and human calcitonin gene-related peptide(8-37) (hCGRP(837); 0.1-1.0 microM). | lld:pubmed |
