Methods Radionuclide ambulatory renography and color Doppler renal hemodynamics were studied in 30 patients with esential hypertension and left ventricular hypertrophy and 21 healthy control group. The glomerular filtration rate,renal index and the distribution of intrarenal artery were investigated.The resistive index, the systolic peak velocity,andthe low diastolic flow velocity and acceleration time of theintrarenal arterial flow were measured. Results Compared with control group the density of intrarenal artery of patients with esential hypertension and left ventricular hypertrophy were significantly decreased.

对30例高血压伴左室肥厚病人及21例年龄相当的健康人对照组行核素动态肾功能检测及彩色多普勒超声肾血流动力学检查，测定肾小球滤过率和肾脏指数及肾内动脉分布，段动脉、叶间动脉的阻力指数，血流峰速加速时间，收缩期最大血流速度，舒张期末最低血流速度。

Salt absorption, transpiration induced water uptake and the radial reflection coefficient of the root system of arrowleaf saltbush were measured in order to analyze ultrafiltrational characteristics of its root system in relation to salt tolerance of the plant.

对耐盐蔬菜三角叶滨藜在盐胁迫下的蒸腾吸水量、Na吸收和根系径向反射系数进行了测定，分析其根系超滤特性与植物耐盐性的关系。

This indicated that arrowleaf saltbush was able to change the ultrafiltration characteristics of its root system and reduce radial reflection coefficient of the root, thus lowering the risk of higher xylem tension leading to xylem cavitation and able to reduce salt absorption to avoid damage of salt over-accumulation to the plant.

说明三角叶滨藜在盐胁迫下一方面通过改变根系的超滤特性，降低根系径向反射系数来防止木质部拉力过大导致的木质部空化的危险，另一方面通过减少对盐分的吸收来避免盐分过多积累对植株的伤害。

Methods RI and PI of main renal artery and interlobar artery were obtained by color Doppler ultrasonography within the first week of transplantation.Then they were correlated with allograft glumerular filtration rate at 1 year.

在100例无并发症肾移植患者中，应用彩色多普勒超声，于肾移植术后1周内，测量移植肾肾动脉和叶间动脉的阻力指数和搏动指数，并与术后1年的移植肾肾小球滤过率进行相关分析。

Method］Raw material was extracted by 50% ethanol,then purified by acetic ethyl.The extract was injected into LC/MS after filtering with micromembrane.

方法］叶下珠药材，以50%乙醇提取，乙酸乙酯萃取，萃取液过微孔滤膜后，采用LC/MS对各成分分离鉴定。

The polyaluminum flocculates with different B values were prepared by addition NaOH solution to AlCl〓 solution on using different methods. The characteristics of solution chemistry and species distribution in the polyaluminum solutions were examined completely and deeply by the potentiometry,〓Al NMR, Ferron timed comlexation spectrophotometry, Na〓SO〓 precipitation and ultrafiltration method.

应用多种化学分析技术及现代分析仪器，如电位滴定、Ferron逐时络合比色、Na〓SO〓沉淀、超滤膜过滤、X-衍射、富里叶红外光谱、扫描电镜等对铝盐的水解聚合反应过程、形态分布及其结构特征进行了全面深入地分析研究。
