Abstract:

The purpose of this study was to test the hypothesis that the dietary L-arginine supplementation has beneficial effects on edema disease. Experimental animals were 156 KunMing mice, randomly assigned to arginine group 1 (0.6% arginine + basal diet, n = 44), arginine group 2 (0.6% arginine + basal diet, n = 44), control group 1 (1.22% alanine + basal diet, n = 34) and control group 2 (1.22% alanine + basal diet, n = 34). After 3 days of adaptive feeding and a 7 days treatment period with the prepared feed, all mice were challenged by intraperitoneal injection of Escherichia coli O139 (E.coli) at LD₅₀ (2.53 × 10⁸ CFU/ml). Arginine group 2 and control group 2 were used to calculate the mortality after twenty hours of injection. Serum concentrations of platelet- activating factor (PAF), interleukin (IL)-2, interleukin (IL)-10, secretory immunoglobulin A (sIgA), superoxide dismutase (SOD) activity, total antioxidant capacity (T-AOC), cyclic 3',5'-adenosinemonophosphate (cAMP) and cyclic 3',5'-guanosine monophosphate (cGMP) were measured in arginine group1 and control group1 in a ten-hour interval for three times. The serum concentration of PAF was much lower (P < 0.01) in arginine group than in alanine group in all the time. Additionally, T-AOC and SOD activity in the experiment group increased significantly (P < 0.05) in the first ten hours after initial injection. Unfortunately, T-AOC and SOD activity in arginine group became quiet (P > 0.05) compared to the control group after that, except T-AOC was greater (P < 0.05) in arginine group than in the control group in twenty hours of initial injection. Meanwhile, arginine supplementation had little effect on the mortality of mice, serum IL-2, sIgA, cAMP and cGMP level. In conclusion, dietary arginine supplementation can partially attenuate the damage caused by edema disease, but have little effect on the clinical results.
