Using TV Frarne To Frarne and two-point photoelectrcity method to measure the effect of TMP to mesentery small artery internal diameter,red cell velosity and vasomotion. Results obtained TMP have a density depending function to depress the blood pressure. The blood pressure begin to get down continously for one minute after given the medicine 30seconds, 8mg/kg group have a greater depressive effect than 4mg/kg group. Flowing the blood pressure's depression, 8mg/kg groups mesentery tiny artery's red cell velocity decreas, but there is no change of interior diameter. 2mg/kg and 4mg/kg groups' effects are no clear. Under the vivid microscope, at the tiny artery (30 ̄50μm) level ,it has been directly proved that TMP have a inhibition on the vasomotion caused by Moradrenaline. And also found that 16mg/kg group has a longer continous peried than 8mg/kg group. While the artery blood pressure doesn't change, the tiny artery flow will change periedically with the vasomotion. When the tiny artery dilates, the blood flow will increase. TMP depress the vasomotion caused by Noradrenaline, there was no significant changes between the increased diameter and the diameter before Noradrenaline was injected, what demonstrated that TMP's essential function is to depress the vasomotion caused by Noradrenaline not the dilation of vessel.

在全身动脉血压控制下应用显微录像静画步进和二点光电法同步测定了川芎嗪对话体家兔肠系膜细动脉的内径、血流速度和血管运动的影响及其相互间的关系。结果发现川芎嗪有浓度依赖性的降压作用。给药后30s血压开始下降并持续1min。8mg/kg比4mg/kg给药组降压作用大,2mg/kg组效果不明显。伴随血压下降8mg/kg给药组细动脉血流速度减慢,但内径无变化,4mg/kg和2mg/kg组效果不明显。又在活体显微镜下在30~50μm细动脉水平直接证明了川芎嗪有抑制局部投予去甲肾上腺素引起的血管运动的作用。并发现16mg/kg比8mg/kg给药组抑制作用时间长。即使全身血压不变,细动脉血流也随血管运动周期变化,细动脉舒张血流量增加。将给去甲肾上腺素前与给川芎嗪后的内径对比变化不明显。提示TMP的作用本质是抑制去甲肾上腺素引起的血管运动而不是扩张血管。
