摘要
We comment on an article published by Mansouri et al in the World Journal of Diabetes.L-arginine(L-Arg),a dietary supplement,is a precursor of nitric oxide,can improve cardiovascular disease,and it is important for treating heart disease and hypertension.Previous studies have demonstrated a beneficial effect of L-Arg on diabetes.In the study by Mansouri et al,L-Arg moderately increased blood glucose levels in normal rats.However,in diabetic rats,L-Arg significantly increased lipid levels,which is different from the findings of previous studies.This study demonstrated that a safe dose of 0.5 g/kg in diabetic rats can improve the lipid profile and decrease body weight.However,high doses(1 g/kg or higher)may aggravate damage to myocardial tissue in diabetic rats by increasing blood glucose,inflammation,and oxidative stress.Therefore,this study further demonstrated that high doses of L-Arg can exacerbate myocardial injury in diabetic patients.
