An apparatus is described for the study of foam formation in double contrast preparations in vitro. Antifoaming agents are shown to be of considerable benefit to the double contrast technique, silicone and silicone-free antifoamers being equally effective. Silicone antifoamers are preferred because of their wide clinical acceptability. Antifoamer formulation and concentration are found to be critical factors in determining efficacy of foam suppression, and may lead to erroneous results in the clinic.
描述了一种用于体外研究双重对比制剂中泡沫形成的装置。结果表明,消泡剂对双重对比技术有很大益处,含硅和不含硅的消泡剂效果相同。由于含硅消泡剂具有广泛的临床可接受性,因此更受青睐。发现消泡剂的配方和浓度是决定泡沫抑制效果的关键因素,可能会在临床上导致错误结果。
