摘要

在兔和一名志愿者(内科医生)的吸入气管支气管造影中，获得了良好的支气管轮廓图和详细的粘膜结构成像。有系统地适当应用，20-40微米的铌颗粒不会渗透到肺泡中，并迅速(在1-5天内)从支气管中清除。对小鼠的研究表明，铌粉是不溶性的，不会刺激组织，也不会被吸收。它也是无毒的。

[Niobium powder--a new x-ray contrast medium for tracheobronchography].

In inhalation tracheobronchography with niobium powder in rabbits and a volunteer (physician), excellent contour bronchograms with detailed imaging of the structure of the mucosa were obtained. With methodically proper application the niobium particles of 20-40 microns do not penetrate into the alveoli and are quickly (within 1-5 days) eliminated from the bronchi. Investigations with mice have shown, that niobium powder is insoluble, does not irritate tissues and is not resorbed. It is also nontoxic.
