This study was performed to compare the amount of blood flow from left and right side heart using Doppler echocardiography and Fick method. The pulmonary blood flow (Qp), aortic blood flow (Qs) and Qp/Qs ratio were noninvasively evaluated by two dimensional Doppler echocardiography in 10 patients with ventricular septal defect in children, aged 2 years to 15 years (mean+/-SD=7.1+/-4.9 years). Cardiac catheterization was performed within 2 days after examination of Doppler echocardiography in all patients. Systemic and pulmonary blood flow was calculated by using Fick principle, based on measured oxygen consumption and measured blood oxygen saturation. The Doppler frequency shift was analyzed by computer system combined with Meridian Echocardiography System. Comparison of Qp, Qs and Qp/Qs ratio obtained by invasive methods and by two-dimensional pulsed wave Doppler echocardiography showed a correlation of 0.679 in Qp, 0.710 in Qs and 0.639 in Qp/Qs ratio (p<0.05).

We had previously reported the purification of bovine lung natural surfactant-phospholoipd (PNSL)and the assessment of it's surface physical properties in vitro. To observe the clinical effectiveness of PNS-L in vivo, the degree of improvement of thoracic pressure-volume, compliance and histological changes following PNS-L instilation in premature rabbits with respiratory distress syndrome(RDS)were investigated. Rabbits, delivered prematurely by cesarean section at 27 days, treated with PNS-L via tracheostomy, were enrolled the study group. Two control groups were premature RDS rabbits (no treatment with PNS-L)and mature rabbits. We compared the results of thoracic pressure-volume changes during deflation phase and lung compliance changes among PNS-L treated study group and two control groups, and compared the results of aefated lung area ratio (%) on histologic samples among PNS-L treated study group and two control groups by the methods of IBSA-2000. There were significant improvements of thoracic pressure-volume during duflation phase(p<0.001), lung compliance (p<0.01, p<0.005, p<0.001) and increased acrated area histologically (p<0.005)in PNS-L treated study group compared with premature control group. It was suspected that PNS-L had contained the effective survace physical properties as a function of pulmonary surfactant. And improvement of pulmonary ventilatory functions and histological characteristics, were observed in PNS-L treated RDS model in vivo study.
