The Zeta-potential of the barium sulfate particles in increasing. concentration of different electrolytes was measured by the eletrophoretic method in a Burton Cell. The results were compared with the corresponding sedimentation volume. It was found that the Zeta-potential ranging from 50 mV to 66 mV favored the...

Deflocculation state was considered to be necessary for better fluidity and spreadability of barium sulfate suspension taken as an X-ray contrast medium in the examination of gastro-intestinal tract. The Zeta-potential of the barium sulfate particles in increasing. concentration of different electrolytes was measured by the eletrophoretic method in a Burton Cell. The results were compared with the corresponding sedimentation volume. It was found that the Zeta-potential ranging from 50 mV to 66 mV favored the deflocculation of the suspension, while that below 22 mV, flocculation was affected. The viscosities of 100%, 130% and 150% barium sulfate suspensions were measured using Hoppler's Rheo-viscometer. The viscosity dropped quickly at first on the addition of electrolytes, and then increased to some extent with further increase of electrolyte concentration. The minimum viscosity was considered to reflect complete deflocculation of the suspending particles. The electrolyte concentration producing minimum viscosity was shown to be the most effective deflocculating agent tested, while sodium pyrophosphate and sodium citrate are less effective.The flocculation of the barium suspension by the gastric fluid after ingestion often leads to some troubles to the roentgenologists. We examined the ability of different electrolytes to retard such flocculation by means of the viscosity method.

测定了硫酸钡不同工艺制成品的粒度分布。证明北京三厂中间产品(湿膏)本来粒度很细有97%是在4μm以下,但烘干后成品粒度变粗,80μm以上的粒子占62%。这对造影效果会产生重要影响。喷雾干燥产品的粒度分布与原湿膏基本相同。用电泳法测定了硫酸钡混悬剂的动电位,确定硫酸钡是荷负电的。混悬剂的动电位在22mv以下可产生絮凝,适合于反絮凝的动电位是在50~66mv之间。电解质中六偏磷酸钠、焦磷酸钠和柠檬酸钠的反絮凝效力是按上列顺序减低的。例如配制100%硫酸钡混悬液三种电解质最适宜的浓度分别为5×10~(-3)M、2×10~(-2)M和3×10~(-2)M。本文用粘度分析法研究了混悬液的絮凝反絮凝过程,所得结果与动电位和沉降容积的结果基本吻合,惟粘度法方便迅速并能反映出细小的变化,可用数字和曲线作鲜明的对比。但此法要求颗粒要细(10μm以下)否则会发生机械性阻碍无法测定。

Carbon dioxide produced from mixture of hydrochloric acid with sodium bicarbonate was used as contrast in this study.It was proved to be safe and effective in experimental and clinical application of 2118 patients.Comparison analysis of contrast echocardiographic diagnosis with surgical findings showed: 1) this technic was used to detect right to left shunt with success in 179 patients and a little contrast in left ventricle found by cough provocation in 21 patients with small ventricular septal defect(0.3-0.6cm);...

Carbon dioxide produced from mixture of hydrochloric acid with sodium bicarbonate was used as contrast in this study.It was proved to be safe and effective in experimental and clinical application of 2118 patients.Comparison analysis of contrast echocardiographic diagnosis with surgical findings showed: 1) this technic was used to detect right to left shunt with success in 179 patients and a little contrast in left ventricle found by cough provocation in 21 patients with small ventricular septal defect(0.3-0.6cm); 2) the contrast effect was safisfactory as well as negative contrast effect. The sensitivity, specificity and predictive accuracy for diagnosis of atrial septal defect were 97.9, 99.6 and 99.2%; and for ventricular septal defect 98,95.9 and 94.4% respectively; It was shown that the technic and contrast used in this study increased the diagnostic rate and sensitivity of contrast echocardiography.

本组采用盐酸、碳酸氢钠混合产生的CO_2作为超声造影剂、经动物试验及2118例临床应用证明其安全、有效。793例已手术病人的手术结果与超声造影诊断对比分析表明:①、右心二维超声造影能明确诊断先心病右向左分流。②、这种造影剂能改进造影效果,显示清楚的负性显影区,因而可诊断常见先心病左向右分流,显著的扩大了超声造影法诊断范围,提高了敏感性。

本文报道了由生孢噬纤维素细菌(Sporocy-tophaga)产生的多糖作为一种辅助添加剂,应用到医用硫酸钡的研制上,起到了很好的保护作用和絮凝作用。从而,大大地提高了医用硫酸钡的质量,得到比较理想的造影效果。同时,也简化了医用硫酸钡的生产工艺,降低了生产成本。
