Effect of C.oil on immunohistochemical and Western blot analysis iNOS expression after 24 hrs of ischemia in the brain.(a): Photomicrographs (representative of 5 photomicrographs) showing inducible nitric oxide synthase (iNOS) immunoreactivity in sham-operated group (A-C); peanut oil treated ischemia group (D-F), and ischemia-C.oil post-treated groups (G-I) after 24 hrs of clot implant. Sections were immunolabeled with a polyclonal anti-iNOS antibody, which was observed as green fluorescence (B, E & H) and counterstaining by DAPI is shown as blue fluorescence (A, D & G). The merger is shown in C, F & I. Magnification: 40×. (b) iNOS expression by immunoblotting. Bar chart shows the quantification of bands. Lower Panel showing the representative bands for iNOS and β-Actin as lane 1: sham-operated, lane 2: Peanut oil treated ischemic, and lane 3: C.oil post treated (50 μg/lane). Data are expressed as mean ± S.E.M of five animals per group. (*P < 0.05) was considered highly significant when comparisons were made with the peanut oil treated ischemic group by one way ANOVA followed by Newman Keuls post hoc test.
