The field surveys and lab experiments were designed to study the distribution and source of PAH' pollution in water, sediment; the PAH' concentration and distribution in marine fish organ (of the fish Lateolabraxjaponicus and Pagrosomus major); the PAH' BCF factors of liver and bile in marine fish (Lateolabrax japonicus and Pagrosomus major); the relationship between PAH' exposure and biochemical response and the metabolic rate of naphthalene and pyrene in fish bile.
研究了多环芳烃在厦门西海域养殖区的表层海水、沉积物中的含量分布,并应用PAH型式的分子指纹方法分析了其来源特征。指出:(1)厦门西海域养殖区海水和沉积物的多环芳烃污染已很严重。表层海水的∑PAH(16种PAH)已达4.55μg/L,沉积物的∑PAH已达2.86μg/g。

Results showed that more than 72% PAH at soil/oil ratio of 1:1 was removed from high (200 mg/Kg) and low (50 mg/Kg) PAH contaminated soil with the equilibrium time 24 h. It was estimated that soybean oil can remove more than 70% PAH from 4200 mg/Kg contaminated soil. If a sequence of double extraction of the
结果显示,土壤和大豆油於 1:1 比例,平衡时间为 24 小时条件下,对於 anthracene (50, 200 mg/Kg)土壤脱附效率皆为 72%,计算萃取 4200 mg/Kg 的污染土壤,其萃取效率仍可维持於 70%优於 SDS、TX-100、Tween 80 等界面活性剂。

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。
