Abstract

In the present study, by comparing the responses in wild-type mice (iNOSWT) and mice lacking (iNOSKO) the inducible (or type 2) nitric oxide synthase (iNOS), we investigated the correlation between endogenous nitric oxide (NO) and prostaglandin (PG) generation in carrageenan-induced pleurisy. The inflammatory response in iNOSKO mice was significantly reduced in respect to iNOSWT animals, as demonstrated by the exudate volume (-63%) and numbers of infiltrating cells (-62%). The levels of NOx in the pleural exudate from carrageenan-treated mice were significantly (p <0.01) decreased in iNOSKO mice (16 ± 7.6 nmoles/mice) compared to iNOSWT animals (133 ± 9 nmoles/mice). Similarly, the amounts of PGE₂ in the pleural exudates of carrageenan-treated animals were significantly (p <0.01) lower in iNOSKO compared to iNOSWT mice (120 ± 20 pg/mice vs. 308 ± 51 pg/mice). Also the amounts of 6-keto-PGF_1α produced by lungs from carrageenan-treated iNOSKO mice (1.01 ± 0.10 ng/tissue mg) were significantly (p <0.01) reduced compared to iNOSWT carrageenan-treated mice (2.1 ± 0.09 ng/tissue mg). In conclusion our results confirm, by the use of iNOSKO mice that in carrageenan-induced pleurisy NO positively modulates PG biosynthesis.
