查询词典 cardiovascular

The cardiac effects of Ado are negative chronotropic; dromotropic; inotropic and coronary vasodilation which serves as a negative feedback regulator in the cardiovascular system in order to rectify the oxygen supply/demand imblance.

Result and contrast group quite, IMT of cardiovascular ill patient, carotid β, EP is elevatory, serum bilirubin is reduced.

结果和对照组比较，心血管病患者IMT、颈动脉β、EP升高，血清胆红素降低。

SO2 is endogenously generated in cardiovascular system, and the SO2 content in arteries is higher than that in other organs. GOT enzyme and GOT mRNA expression are low in arteries, and this phenomenon may be related with local metabolism.

SO2可在心血管系统内源性产生，动脉血管中SO2含量高于组织器官中的含量，GOT酶及GOT mRNA的含量在动脉血管中较低，这可能与局部代谢及作用有关。

The limb muscular exercise is more effective in maintaining lower limb muscle and body weight, while the bicycle ergometric exercise provided more improvement in cardiovascular function.

下肢肌力训练在下肢肌肉和体重维持上锻炼效果相对较好，自行车功量计训练对心血管功能方面的改善作用较明显。

In the present study, head-down tilt bed rest was used to simulate microgravity. We observed and compared the effects of lower limb muscular exercise with bicycle ergometric exercise during 30 days of -6°HDT bed rest on the responses of lower limb muscle and cardiovascular systems.

采用何种体育锻炼方法才能够最有效地预防和对抗航天失重环境对机体的影响，仍然是航天医学所面临的主要问题之一。

In conclusion, this study investigated the effects of lower limb muscular exercise with bicycle ergometric exercise during 30 d HDT bed rest on limb muscle and cardiovascular system. We found that limb muscular exercise and the bicycle ergometric exercise in some extent can improve adverse effects following simulated microgravity.

总之，本实验通过比较30 d头低位卧床期间下肢肌力训练和自行车功量计训练对下肢肌肉和心血管系统的影响，发现下肢肌力训练和自行车功量计训练可在一定程度上对抗模拟失重所致的不良影响。

The cardiac systole and pump functions decrease significantly during 30 d HDT bed rest. The limb muscular exercise and the bicycle ergometric exercise may improve the cardiovascular system to some extent. Further, the bicycle ergometric exercise is the better one.

30 d头低位卧床可引起心脏收缩泵血功能下降，下肢肌力训练和自行车功率计训练可在一定程度上改善心血管功能，其中自行车功率计训练的对抗效果更佳。

Objective To observe the effect of low dose remifentanil on cardiovascular response to tracheal extubation of patients.

目的：观察拔管前小剂量瑞芬太尼对预防全麻气管拔管反应的临床效果。

Main changes of ECG were arrhythmia, Left ventricular high-voltage, Ventricular hypertrophy, bundle branch block and fascicular block, and ST-T abnormal, etc. Long-term exposure to high temperature has adverse effect on cardiovascular system.

结果 高温组的心电图异常率高于对照组(χ^2=12.00， P.01)，主要改变为心律失常，左室高电压、心室肥厚、束支与分支传导阻滞、ST-T异常等。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
