耳蜗血流障碍与听力丧失有着密切联系[1～4 ] 。乙酰胆碱(Ach)作为一种神经递质和血管舒张物质参与了许多血管床的调节活动[5～10 ] 。实验已证实,在大鼠和猫的脑血管床有大量的胆碱乙酰化酶免疫反应阳性的神经纤维[8] ;Ach和它的模拟剂能引起内耳螺旋动脉(spiralmodiolararter
Cochlear blood flow disorders and hearing loss are closely linked [1 ~ 4]. Acetylcholine (Ach) is involved in the regulation of many vascular beds as a neurotransmitter and vasodilator [5-10]. Experiments have shown that rat and cat cerebrovascular beds have a large number of choline acetylase-positive immunoreactive nerve fibers [8]; Ach and its mimics can cause the inner ear spiral arteries (spiralmodiolarrter
