ABSTRACT
<p><b>OBJECTIVE</b>To observe the effects of training on plasma content of NO, ET and NO/ET system in rats fed with high methionine diets.</p><p><b>METHODS</b>Male Wistar rats were randomly divided into normal diet group (CR), high methionine diet group (MR) and high methionine diet plus 90 min swimming group (T+ MR). Rats in MR and T+ MR group were fed with the diet which contained 3%of methionine for eight weeks, but rats in control group were fed with ordinary diet. After breeding for eight weeks homocysteine (Hcy) level, T-NOS, NO and ET were measured.</p><p><b>RESULTS</b>Plasma homocysteine of MR increased twofold as compared with that of CR,whereas plasma NO/ET of MR descended significantly (P < 0.05), suggesting that hyperhomocysteinemia was induced by the high methionine diet, and plasma NO/ET system was out of balance. Plasma homocysteine content of T+ MR obviously descended, plasma T-NOS, NO and NO/ET ascended obviously (P < 0.05) as compared with that of MR, and the above indicators of group T + MR were not different as compared with that of CR (P > 0.05).</p><p><b>CONCLUSION</b>Proper training can descend plasma homocysteine level of rats fed with high methionine diet and better balance between NO and ET to prevent developing of hyperhomocysteinemia.</p>
