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。

METHODS: Sixty healthy Sprague-Dawley rats were randomly divided into 3 groups: 6 rats in normal control group, 6 rats in EGb treating normal IOP group, and the other 48 rats were established chronic high IOP models of rats by cauterizing two episcleral veins. Then 30 rats satisfying experimental level were selected and randomly divided into five groups: 6 rats in physiological brine treating group, and the other 24 rats were divided into four experimental groups according to the dose of EGb: group A, EGb 50mg/; group B, EGb 100mg/; group C, EGb 150mg/; and group D EGb 200mg/. After the treating time of 1 month, the rats were sacrificed on schedule. Flat preparation of whole retinaes was stained distinctively and neuron counting in retinal ganglion cell layer from both eyes of each rat were performed to evaluate neuron situation.

Our result showed that P450scc expression was observed in hippocampus, habenular nucleus, neuron nucleus of thalamus and hypothalamus, and cerebral neocortex. The colocalization of P450scc and NeuN demonstrated that most of P450scc exist in neuron cell in these regions.
