| pubmed-article:8513983 | pubmed:abstractText | Capsaicin and papaverine are potent vasorelaxants with strong gastroprotective activity against damage induced by absolute ethanol. This protection was originally attributed to the increase in gastric mucosal blood flow (GBF) and the present study was designed to determine the possible role of nitric oxide (NO) and prostaglandins (PG) in the protective and hyperemic effects of capsaicin and papaverine on rat gastric mucosa. We found that the pretreatment with capsaicin (0.1-0.5 mg/kg i.g.) or papaverine (0.1-2 mg/kg i.g.) reduced dose dependently the area of ethanol-induced lesions, the ED50 being 0.3 and 1 mg/kg, respectively. This protection was accompanied by a gradual increase in the GBF. Intravenous injection of N omega-nitro-L-arginine (L-NNA; 1.2-5 mg/kg), a selective blocker of NO synthase, which by itself caused only a small increase in ethanol lesions, reversed dose dependently the protective and hyperemic effects of capsaicin and papaverine against ethanol-induced damage and attenuated the increase in GBF induced by each of these agents alone. This deleterious effect of L-NNA on the gastric mucosa and the GBF was fully antagonized by L-arginine (200 mg/kg i.v.) but not by D-arginine. L-arginine partly restored the decrease in GBF induced by L-NNA. Pretreatment with indomethacin (5 mg/kg i.p.), which suppressed the generation of PG by 85%, slightly enhanced the mucosal lesions induced by ethanol but failed to affect the fall in GBF induced by this irritant. Gastroprotective and hyperemic effects of capsaicin and papaverine were partly reversed by indomethacin suggesting that endogenous PG are also implicated in these effects.(ABSTRACT TRUNCATED AT 250 WORDS) | lld:pubmed |
