AIM: To study the influence of levothyroxine on rat aorta contraction and nitric oxide (NO) release. METHODS: levothyroxine was administered 0.75 mg·g~(-1)×8d sc,and responses of isolated rat aorta rings were recorded and compared in the absence and presence of L-Argnine (LArg) and N~ω-Nitro-L-Argnine(L-NOARG) on norepinephrine (NE)-induced contraction. RESULTS: AUC
