Vaccinium macrocarpon Aiton Extract Ameliorates Inflammation and Hyperalgesia through Oxidative Stress Inhibition in Experimental Acute Pancreatitis

Figure 4

The hydroethanolic extract of fruits of Vaccinium macrocarpon (HEVm) reduces abdominal hyperalgesia in L-arginine-induced pancreatitis. Animals were submitted to injection of L-arginine or saline, treated with HEVm (50, 100, or 200 mg/kg) or vehicle (saline), and euthanized after pancreatitis induction. The variation (Δ) of the threshold force to cause withdrawal behavior was calculated by subtracting each time point from basal values (0 h) and was expressed in g for the intensity of stimulus for . versus the respective saline + vehicle group; or versus the respective L-arginine + vehicle. Two-way ANOVA (interaction of treatment versus time: and F(15,81) = 3,712) followed by Bonferroni’s test.
