Objective The purpose of present study was to evaluate the relative contributions of prostacyclin (PGI2) and the expression of COX mRNA in the hyperdynamic circulatory state of chronic portal hypertensive rats. Methods Twenty male Sprague-Dawley rats were divided into three groups: intrahepatic portal hypertension by injection of CC14, prehepatic portal hypertension by partial stenosis of the portal vein and sham-operated controls.

目的 研究门静脉高压症鼠血浆前列环素(PGI2)水平、血管和小肠中环加氧酶基因表达以及内脏血流动力学的变化，探讨PGI2、COX mRNA表达与门静脉高压症高血流动力学之间的关系。

We first discovered the presystolic wave of PRG and suggested that a complete PRG should be consisted of 4 waves, namely, a, p〓, S, D.

Methods There were to patients of diabetes and 35 patients of non-diabetes in this study. The diameter, inter median thickness, peak systolic velocity, end diastolic velocity, pulsatility index, and resistance index of bilateral common femoral artery, superficial femoral artery, profunda femoral artery, popliteal artery,and pedal artery,and whether there was arteriosclerotic plaque or occlusive diseases were examined with color Doppler ultrasonogh.

糖尿病组70例，非糖尿病组35例，分别应用彩色多普勒超声观察双侧股总动脉、股浅动脉、股深动脉、腘动脉、足背动脉的血管内径、内－中膜的厚度、收缩期最大峰值血流速度、舒张期末血流速度、搏动指数、阻力指数；观察血管内有无硬化斑块、有无完全性和不完全性动脉闭塞。

As a result, the outflow of right ventricle is into the aorta and the outflow from the left ventricle is into the pulmonic trunk.

结果导致右心室的血流进入主动脉而左心室的血流则进入肺动脉。

Objective To investigate the possibility of using laser Doppler flowmetry to study dental pulpal blood flow.
