Involvement of Nitric Oxide in a Rat Model of Carrageenin-Induced Pleurisy

Figure 4

Effects of NOC-18 and L-arginine on rat Cg pleurisy and nitrite/nitrate levels. NOC18 or L-arginine was injected into the pleural cavity immediately before Cg injection. The exudate volume (a), cell number (b), and nitrite/nitrate levels (c) in the pleural exudates were determined 6 hours after Cg injection. Data are expressed as mean ± S.E.M. of 6 to 8 rats. ${}_{}{}^{*}P<.05\text{,}$${}_{}{}^{**}P<.01$ as compared to the Cg group.
