Intracisternal injection of RX-77368 abolished abdominal surgery (AS)-induced increase in the number of MHCII+/CD206− (M1 like) macrophages in the gastric myenteric plexus assessed 6-h postsurgery. Top: double staining of MHCII (red) and CD206 (green) in rats treated with intracisternal saline (10 µl, −1 h)/sham operation; intracisternal saline/AS; intracisternal RX-77368 (50 ng/rat, −1 h)/sham operation; and intracisternal RX-77368 (50 ng/rat, −1 h)/AS. Bar = 100 µm. Bottom: quantitative analysis of macrophages counted in 20 optical fields/rat (475 × 475 μm/field) with each field containing a ganglium. M1, MHCII+/CD206−; M2, MHCII−/CD206+. Each column represents means ± SE of no. of rats indicated at the bottom. *P < 0.05 vs. M1 in saline/sham; #P < 0.05 vs. M1 in saline/AS group; +P < 0.05 vs. M1 in RX-77368/sham group; &P < 0.05 vs. M1 in RX-77368/AS group.
