Results Intra-articular hemorrhage was observed in 1 patient and intra-osseous hemorrhage in 7 patients. The injury of retinacular arteries and reduction of blood supply were found in each case. In the presence of hip traction, blood flow of retinacular arteries reduced markedly. Few branches and little femoral head blood perfusion were observed in all of retinacular arteries, while hip joint was internally rotated with the sick leg straightened in the patients.

结果 12例中髋关节囊内出血1例，骨内出血7例， 12例均出现持带动脉损伤和血供减少；患髋牵引时支持带动脉供血减少；髋关节维持伸直内旋位时所有支持带动脉无明确显影或仅显示其主干。

After administration of L-N〓-nitro-Arginine, a specific antagonist of NOS, it was found that the basal and stimulated NO release of blood vessels (aorta, internal carotid, renal and mensenteric artery) was decreased further. The increase of coronary blood flow stimulated by Ach was also reduced further, while the platelet aggregation degree and erythrocyte aggregation index increased significantly. Pathological examination indicated that aortic endothelium was destroyed, the blood vessels in cerebral, cardiac and renal tissues were hypertrophied further and some were almost occluded. The above fin dings resulted in SHR feeded with L-NNA having high incidence of stroke rate and high degree of renal cirrhosis when compared to control SHR. The infarct and hemorrhagic focuci in cerebral tissues, infarct focuci in cardiac tissues, atrophy and hyalinedegeneration of renal glomeruli and degeneration even necrosis of renal tubuli in renal tissues were al so found. The increase ratio of brain and heart to body weight and decrease ratio of kidney to body wei ght further demonstrated that the cerebral, cardiac and renal injuries were aggravated.

在上述结果的基础上进一步给予SHR NOS特异性拮抗剂左旋亚硝基精氨酸后，血管(胸主、颈内、肾及肠系膜动脉)NO基础释放及激动剂刺激释放进一步减少，Ach刺激冠脉流量的增加和胸主动脉内膜NOS活性也进一步减少，血小板聚集程度及红细胞聚集指数显著上升，病理切片显示胸主动脉内皮细胞破坏明显，脑心肾组织内的血管进一步增厚甚至几乎阻塞，导致饲L-NNA的SHR缺血性及出血性脑卒中发生率显著高于对照SHR，脑体重比显著升高；心肌内出现明显的缺血梗塞疤痕灶，心体重比显著升高；肾小球明显萎缩、玻璃样变性，肾小管也变性甚至坏死，使肾硬化程度显著增加呈颗粒性固缩肾，肾体重比也显著减少。

E. (P.001), which verified that after acupunctured head acu-points, the elas- ticity of the brain artery has been greatly improved and the tense brain artery is relaxed, the blood vessel dilatated, blood flow increased thus the condition of blood cireculation of patients has been improved. The brain tissue is well oxygenated, the brain cells around the focusis well nutriented, and finally speeds up the recovering of brain's function and the brain cell's metabolism.

验证了针刺头部腧穴治疗后能改善〓动脉的弹性，使其紧张度下降、血管扩张、血流量增加，从而改善了中风患者的脑部血液循环，提高了脑组织的氧分压，增加了病灶周围的脑细胞的营养，加速了中风患者大脑功能和脑细胞代谢的恢复。

Using 2MHz pulseultrasonic Doppler probe, the index of hemodynamics such as blood flow rate、audio frequency、vascular pulsation of bilateral vertebral and basilar arteries were detected in order to analyze the diagnosis of cervical spondylosis involoving vertebral artery by Transcranial Color Doppler through the occipital foramen. Results: of all 108 carses, 80 cases were positive(positive rate 74.7%). In CSA group,cases of low flow rate were 45.6%,cases of high flow rate were 28.7%,and cases of no...

为分析经颅多普勒检测椎动脉型颈椎病的诊断价值，采用配对研究方法，用 2MHz脉冲多普勒探头经枕骨大孔窗口，检测左、右椎动脉及基底动脉的血流速度、流向、音频、血管博动指数等血流动力学指标，结果显示 10 8例患者有 80例异常，异常率 74 7%，并发现CSA组低流速者占 45 4 %，高流速者占 2 8 7%，正常流速者占 2 5 9%，与正常对照组间有显著差异(P 0 1)，总体而言，低流速型是CSA的主要特征之一。
