| 摘 要： | 在１４种中国葡萄野生资源上接种南方根结线虫，以根结指数和根际根结线虫数为指标，筛选出华东葡萄、福建葡萄、毛葡萄、万县野葡萄和蛇葡萄属的乌头叶葡萄为抗性资源，燕山葡萄、华北葡萄、山葡萄、刺葡萄、复叶葡萄为病资源，小果野葡萄、同时对其侵染后根组织结构的变化进行了观察，对根系活力，Ｐｒｏ含量及ＰＯＤ活性进行了测定。 |

| Abstract: | AIM:To study the effects of changing right heart load on electrophysiologic parameters in anesthetized dogs. METHODS:Change of right atrial and ventricular load, right atrial and ventricular diastolic threshold (ADT, VDT), right atrial and ventricular relative refractory period (ARRP, VRRP) and right atrial and ventricular effective refractory period (AERP, VERP) were recorded. RESULTS: Increasing right heart load step by step(grade A and B) caused prolongation of ARRP, AERP, VRRP (grade B, P＜0.01), but it was not in ADT and VDT, and atrial and ventricular arrhythmia was not induced. CONCLUSION: Mechanical and partial obstructing blood flow from right atria to right ventricle (changing right heart load)would prolong atrial and ventricular refractory period. |
