Figure 3From: Dietary L-arginine supplementation reduces Methotrexate-induced intestinal mucosal injury in rat Effect of arginine on bax and bcl-2 mRNA expression in gut mucosa following methotrexate induced intestinal damage. Results are expressed as the ratio of the investigated bax and bcl-2 mRNA to ERK. Values are mean ± SEM. CONTR- control, MTX-methotrexate, ARG-arginine. * P < 0.05 MTX and MTX-ARG vs CONTR rats, †P < 0.05 MTX-ARG vs MTX rats.Back to article page
