Finding effective drugs to treat PAH is a problem needed to be resolved. The main purposes of this study therefore were:① To assess the significance of radionuclide ventriculography in the diagnosis of early cor pulmonale and cor pulmonale with right heart failure.② To assess the rule of hemodynamic changes in patients with cor pulmonale especially in those patients who had been in decompensatory phase.③ TO assess the correlation between mean pulmonary artery pressure and right ventricular ejection fraction in order to establish a equation for diagnosing PAH noninvasively.④ To assess the effects of nifedipine , captopril and combining nifedipine with captopril on the treatment of PAH.

本文对慢性肺心病、PAH的无创诊断和有效治疗两方面进行研究，其目的在于：①了解放射性核素检查对早期肺心病和肺心病合并右心衰竭诊断的意义；②了解肺心病病人尤其是失代偿期肺心病病人血流动力学的改变规律，了解平均肺动脉压与右室射血分数等的相关性，探索建立一个无创诊断PAH的回归方程，祈能提供今后临床使用；③观察硝苯吡啶、卡托普利和两药联用对PAP等血流动力学参数的影响。

Dobutamine stress echocardiography, radionuclide ventriculography, and right heart catheterization in the BMC group also showed significant improvement in stroke volume index, left ventricular end-systolic volume and contractility (ratio of systolic pressure and end-systolic volume), and myocardial perfusion of the infarcted region.

Dobutamine压力心脏超音波检查，放射性核脑室造影术和右心导管插入都显示，BMC组的脉搏容积指数、左心室终末收缩容积和伸缩力（收缩压和终末收缩容积比）以及梗塞区域心肌灌注明显改善。

Radiolabeled pharmacological binding assay showed: 1 BmK AS bound specifically to a single class of non-interacting binding sites on both rat brain and cockroach nerve cord synaptosomes with high affinity and low low capacity. The association of BmK AS with both synaptosomes was quick to reach equilibrium, but the dissociation seemed to be only partial. The specific binding of BmK AS was independent of membrane potential, and couldn't be modified by veratridine. Moreover, the binding of BmK AS could be inhibited by native BmK AS, BmK AS1, BmK IT2 and BmK IT on both synaptosomes, but not or partially inhibited by BmK Ⅰ and suggesting BmK AS type neurotoxins might bind to a distinct receptor site on mammal and insect sodium channels with a similar manner from β-scorpion toxins.

二。蝎毒素多肽配体与哺乳动物和昆虫靶离子通道受体的药理结合特性及其靶结合位点的研究：经放射性标记结合和竞争抑制实验表明：1）BmK AS在大鼠脑和蟑螂神经索突触体上有单一非协同性高亲和力低结合容量结合位点，能快速结合并达到平衡，但仅能部分解离，其结合不依赖于膜电位，也不受藜芦碱调节，天然的BmK AS，BmK AS-1，BmK IT2和BmK IT可抑制〓AS与两种突触体的特异结合，而BmK Ⅰ无或仅有部分抑制效应。

Using DNA, radio carbon and computer simulations, Victoria University scientist Adele Whyte of Ngati Kahungunu descent, has worked out that 190 women were in that last push to New Zealand. And there were probably more men, suggesting more than seven waka were used.

维多利亚大学的毛利后裔科学家阿戴尔怀特用DNA、放射性碳测定、和电脑模拟检测出190位女性在这「远征队」里头，而男性可能有更多-代表可能有超过七架独木舟上路。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
