...苷对犬急性心肌缺血的防治作用,本文采用麻醉开胸犬,结扎冠状动脉左前降支(LAD),产生急性心肌缺血模型,测定犬冠状动脉血流量(CABF)和心外膜电图(EECG),心肌梗死面积及血清中天冬氨酸氨基转移酶(AST)、肌酸激酶(CK)、乳酸脱氢酶(LDH)、超氧化物歧化酶(SOD)和丙二...

结论由彩色多普勒超声获得的脐动脉血流量信息,在评价胎盘功能中起着重要作用。
Conclusion the information of umbilical artery blood flow quantity gained by color Doppler ultrasound may play an important role in evaluating the function of placenta.
分别于给药结束后检测门静脉血流量、肠系膜上动脉血流量、门静脉压力、腹主动脉压。
After administration, the blood flow of vena portae, superior mesenteric artery, superior mesenteric artery and pressure of vena portae, average arterial pressure were measured.
方法应用彩色多普勒超声检测70例孕妇(孕13~40周)的正常胎儿的脐动脉血流量。
Methods 70 cases pregnant women (pregnant age ranging from 13 to 40 weeks) were examined by color Doppler ultrasound to measure the umbilical artery blood flow quantities of the normal foetuses.
It occurs because blood flow gets reduced in that blood vessel and so the heart muscle, which is actively beating all the time, needs large quantities of oxygen provided by blood can't get the blood through the vessel.
发病原因是冠状动脉血流量降低,因为心肌搏动永不停歇,随时需要血液供给大量氧气,发病时血液无法正常流过血管
