Protective effect of L-arginine preconditioning on ischemia and reperfusion injury associated with rat small bowel transplantation

Table 1 MDA and MPO levels after heterotopic SBT with or without L-arginine treatment.

	Sham-operated	Control	L-arginine
MDA	2.0±0.22 mmol/g	8.02±3.49 mmol/ga	4.71±1.02 mmol/gc
MPO	0.66±0.105 U/g	1.53±0.068 U/ga	1.03±0.095 U/gc

^aP<0.05 vs sham-operated.

^cP<0.05 vs control.
