| Research Abstract |
It is found that administration of the NOS inhibitor L-NAME at early pregnancy developed hypertension in rat. Blood pressure was increasing, while birth body weight was smaller in L-NAME-treated rats than in saline-treated rats. Acetylcholine (ACh)-induced endothelial nitric oxide (NO) production in uterine artery was higher, although ACh-induced reactive oxygen species production was similar in L-NAME-treated rats. It is suggested that the increased endothelial NO production in uterine artery by administration of L-NAME may protect the development of hypertension in endothelium.
