Abstract : To investigate the effect of stress on homocysteine metabolism in the rat and explore the mechanism as well as the key
regulatory link of stress-induced hyperhomocysteinemia, male Wistar rats were treated with restraint stress while control rats received
routine treatment. By HPLC-fluorometry, the homocysteine level in rat plasma was determined. Cystathionine beta-synthase (CBS)
activity in blood, heart, liver and kidney was measured
