[ Objective] To observe the ultrasonic characteristics of carotid stenosis in patients with ischemic cerebrovascular disease ( ICVD) by color Doppler flow imagine ( CDFI). Study the change of vasomotor reactivity ( VMR) in patients with ICVD of different degree carotid stenosis.

Methods The visceromotor responses ( VMR) evoked by repeated colorectal distention ( CRD) were monitored in lightly anesthetized adult female rats.

方法采用成年雌性大鼠，在浅麻醉状态下记录充胀直肠（CRD）引起的腹肌放电活动，即内脏运动反应（VMR）；

Vascular motor reactivity ( VMR) was used for investigating the cerebrovascular reserve capacity and SPECT was used for investigating he region cerebral blood flow ( rCBF).

测定血管运动反应性（VMR）观察脑血管储备能力及SPECT观察脑局部血流灌注的情况。

The Right of Reserve To examining VMR and predict the risk of ICVD can judge the ability of vessel dilation reserve.

通过对VMR的检测来判断脑血管舒缩功能的储备能力并对ICVD的发病风险进行预测。

Conclusion Estrogen acting in RVM may not only enhance VMR, but also antagonize the analgesic action of morphine.

结论雌激素作用于RVM部位，不仅使VMR增强，还可以拮抗吗啡的中枢镇痛作用。

VMR showed accordance with SPECT, so VMR can be used to reflect indirectly the situation of cerebral vascular blood flow.

VMR和SPECT显示一致性，故临床中对VMR的测定可间接反映脑血流灌注情况。

The VMR's data structure, the handoff operation procedure and the cost function model were presented, and the proposed method's numerical simulation was carried on.

文中描述了VMR的数据结构、操作流程和损耗函数模型，并进行了仿真试验。
