We use the traditional chinese drug "Rochrune" as an acoustic contrast for sonography of the stomach, and success in 643 cases by clinical observation. Rochrune reacts rapidly with hydrochloric acid in gastric juice and produces a great deal of carbon dioxide micro bubbles, which suspends in the gastric juice.Afterdrinking some watre, the homogeneous gastric juice becomes "foamy" . When ultrasonic wave passes through this area,an intensive reflex will be produced. A complete different state will be seen...

We use the traditional chinese drug "Rochrune" as an acoustic contrast for sonography of the stomach, and success in 643 cases by clinical observation. Rochrune reacts rapidly with hydrochloric acid in gastric juice and produces a great deal of carbon dioxide micro bubbles, which suspends in the gastric juice.Afterdrinking some watre, the homogeneous gastric juice becomes "foamy" . When ultrasonic wave passes through this area,an intensive reflex will be produced. A complete different state will be seen as compared wiht the normal drinking in non-reflected area.By using this method,the thickness of stomach wall, its shape, the dynamic changes and the diseased area can be well-demonstrated. Therefore it has practical value in diagnostic use.

我们采用中药“海螵蛸”进行胃声学造影通过643例临床观察获得成功。海螵蛸与胃酸中和之后,迅速发生化学反应,产生大量二氧化碳微气泡,悬浮在胃内液体中,使饮水后胃内质地均匀液体变成“泡沫状”液体,超声通过此区时即可产生密集反射,与正常饮水后胃内液体无回声区截然不同,借此,可以确定胃壁厚度、形态、动力改变及疾患所在,它对胃疾病的诊断具有一定实用价值。

Purpose: To assess hepatic color flow signal enhancing effect of hand agitated perflurocarbon micro bubbles. Materials and Methods: Five normal rabbits were imaged with color Doppler flow imaging technique before and after intravenous injection of three kinds of hand agitated perflurocarbon microbubbles at two dosages. Results: Enhancement of hepatic color flow signal could be observed in 29 of 30 injections. Conclusion: The intravenous injection of hand agitated perflurocarbon microbubbles can...

Results: Enhancement of hepatic color flow signal could be observed in 29 of 30 injections. Conclusion: The intravenous injection of hand agitated perflurocarbon microbubbles can enhance the hepatic color Doppler flow signal and has the potential value of clinical application in future.

目的 :探讨静注手振氟碳微泡造影剂增强肝脏彩色血流信号的能力。材料和方法 :应用彩色多普勒血流图观察5只兔子静注 3种 2个剂量手振氟碳微泡造影剂前后肝脏彩色血流变化。结果 :30次注射中 2 9次肝脏彩色血流信号增强。结论 :静注手振氟碳微泡造影剂能增强肝脏彩色血流信号 ,具有较大的潜在应用价值

Objective:To investigate renal ultrasonographic contrast characteristics with intravenous injection of micro-bubble agent Levovist by ear veins on normal rabbits.Methods:Two dimensional image of echo density of normal renal cortex was evaluated before and after intravenous injection of Levovist in 8 female rabbits, and some parameters of time-density curve such as peak intensity, the area under the curve (AUC) and the mean transit time (MTT) of renal cortex were measured with built-in software. The...

Objective:To investigate renal ultrasonographic contrast characteristics with intravenous injection of micro-bubble agent Levovist by ear veins on normal rabbits.Methods:Two dimensional image of echo density of normal renal cortex was evaluated before and after intravenous injection of Levovist in 8 female rabbits, and some parameters of time-density curve such as peak intensity, the area under the curve (AUC) and the mean transit time (MTT) of renal cortex were measured with built-in software. The contrast intensity of kidney was analyzed by self pre- and post contrast or inter-comparison at different concentrations of Levovist. Results: After intravenous injection of microbubble agent Levovist, two dimensional images of renal contex was greatly enchanced, 3 being Grade Ⅱ , 5 in Grade Ⅲ ,and before contrast the echo intensity of all rabbits' renal cortex were Grade I . The curve of echo-density revealed that the peak time of AUC and PI was 5 seconds after Levovist injection, recovered after 45 seconds. The suitable concentration of Levovist was 300 mg/ml. Conclusion: Levovist is safe, reliable and has characteristics on kidney blood perfusion, and worthy of furthdr application.

目的:探讨正常兔Levovist经耳缘静脉注入后肾脏起声增强特点。方法:8只雌性家兔分别于造影前后评价肾实质的回声强度,利用机器内置的软件绘制肾皮质声学密度曲线,计算曲线下面积(AUC)、灌注峰值(PI)和平均通过时间(MTT),采用自身前后对照或观察不同Levovist不同浓度的肾皮质增强程度。结果:造影后兔肾皮质的二维图像明显增强,3只达Ⅱ级,5只达到Ⅲ级(造影前所有兔肾皮质均为Ⅰ级)。时间强度曲线示造影剂注入5s后AUC、PI达高峰,45s后恢复,Levovist浓度以300mg/ml为宜。结论:Levovist安全、可靠,对正常兔肾脏的血流灌注具有特征性,值得进一步推广应用。
