Abstract］ Objective To assess the endothelium-dependent relaxation in patients with essential hypertension or hypertension smokers by color Doppler flow imaging.Methods With intermittent ultrasound imaging and power Doppler imaging,we measured endothelium-dependent relaxing function in 72 subjects 24 of whom with essential hypertension,24 of whom with both hypertension and smokingand the others as normal control.We measured the diameter of the superficial femoral and brachial arteries at rest,during reactive hyperaemia,re-test and after sublingual glyceryl trinitrate for evaluating the endothelium-independent dilatation in subjects.The level of plasma NO,ET,PGI2,and TXB2 were determined.

摘要］ 目的探讨原发性高血压及高血压合并吸烟患者血管内皮依赖性舒张功能的改变方法采用彩色普勒高频超声的间歇成像和能量多普勒成像，对24例原发性高血压患者、24例高血压合并吸烟患者及24例正常血压无吸烟史者的血管内皮依赖性舒张功能，包括静息时血管内径、增加流量引起的血管舒张、硝酸甘油引起的血管舒张等，以及对血浆氧化氮、内皮素、血栓素B2（TXB2）和列腺环素（PGI2）等血管活性物质进行检测并比较分析。

Figure 9 shows the configuration of the experimental equipment employed in this research. The thermal input is provided primarily by a DC power supply. In addition, a 600W thermostatic tank at the heat exchange section is used to control the water temperature, and it works with a flow regulator to remove heat through the water jacket. Thermocouples are separately embedded at the inlet and outlet of the water jacket to monitor the temperature change. In the course of the experiment, each of the heat spreaders is enclosed by heat-insulating materials to prevent heat loss. The following are the main experimental parameters
