Essential hypertension caused by neurovascular compression of the left ventrolateral medulla was associated with malbalance of vasomotor center in the dorsal medulla. The possible pathogenesis was the following:① An irritation of the left RVLM by pulsatile compression of an ectatic vessel would increase activity of central sympathetic neuron.② Neurovascular compression at the REZ of the cranial nerves Ⅸ and Ⅹ decreased excitation of parasympathetic nerve.③ Decreased sensitivity of afferent inputs to neuron of nucleus tractus solitarii in the sensory area lead to hyperactivity of central sympathetic nervous system due to pulsatile compression of the left RVLM.④ Neurocompression of the left RVLM and REZ in the left cranial nerves Ⅸ and Ⅹ lead to an overactivity of central renin angiotensin system.

3，结论：左侧延髓腹外侧Ⅸ、Ⅹ颅神经REZ动脉血管压迫所导致的高血压的发生与左侧延髓血管运动中枢对血压的调节失衡有关，其可能机制是：①左侧RVLM在搏动性血管压迫刺激下，中枢交感神经元活性增高；②左侧Ⅸ、Ⅹ颅神经REZ受压导致副交感神经兴奋性降低；③感受区孤束核神经元接受迷走神经传入冲动的敏感性减低，导致中枢交感神经活性增高；④左侧RVLM及Ⅸ、Ⅹ颅神经REZ受压引起中枢RAS活性增加。

After jejunal nutrition c-Fos expression in nucleus tractus solitarii was determined by immunohistochemistry method in three groups.

Objective To evaluate the rehabilitation effect of functional unit of brain cortex injury and the connect tractus injury,to offer evidence for the prognose and management.

张盘德 ，孙浩，范小艳目的：了解康复治疗对大脑皮层功能单位与传导通路损伤的疗效和相关机理。

Microinjection of norepinephrine (NE, 30 nmol) into the subnucleus commissuralis of nucleus tractus solitarii of rabbits evoked a decrease of mean arterial pressure and heart rate. These effects were attenuated by application of naloxone (3 nmol) on the same area,which by itself showed no effect on MAP and HR.

于杂种白兔的孤束核联合亚核内微量注射去甲肾上腺素，引起血压降低和心率减慢，将小剂量阿片受体阻断剂纳洛酮注入CNTS，本身不影响血压与心率，但减弱NE在CNTS中的降压降率幅度。

Results: The Fos-like immunoreactive neurons distributed mainly in the spinal trigeminal subnucleus caudalisipsilaterally and medullary visceral zone (MVZ,including nucleus tractus solitarius,ventrolateral medulla and the reticular formation between the first two),ln the sections processed for double staining of Fos and TH immunohisto chemistry, numerous Fos-LI neurons showed also TH- like immunoreactivity in their cytoplasm(Fos-TH cells)in MVZ.

结果：Fos样免疫反应神经元主要分布在同侧三叉神经脊束核尾侧亚核、双侧延髓内脏带(孤束核、腹外侧区及二者之间的网状结构)。在抗Fos 和抗酪氨酸羟化酶的双重免疫染色切片上，见到延髓内脏带内许多Fos阳性神经元的胞浆同时呈TH样免疫反应(Fos-TH双重阳性细胞)。
