The distribution of 133Xe from the bladder was investigated in sliced mice at autoradiography and quantitatively by counting tissue samples from the abdomen and thoracic cavity. Xenon is a highly diffusible inert gas that passes the bladder urothelium. In living mice activity could be seen in the intra-abdominal fat, liver and kidneys; the activity in the kidneys depended on reflux through the ureters. The xenon gas was found in the highest concentration in the lungs where it is expired. The study confirms the assumption that instillation of xenon in the bladder can be used as an indicator for permeability and flow in the wall of the urinary bladder.
通过放射自显影技术并对腹部和胸腔组织样本进行计数定量，研究了切片小鼠膀胱中¹³³Xe的分布情况。氙是一种高度可扩散的惰性气体，可透过膀胱尿路上皮。在活体小鼠中，可在腹腔脂肪、肝脏和肾脏中观察到放射性；肾脏中的放射性取决于通过输尿管的反流情况。在肺部发现氙气浓度最高，它在肺部呼出。该研究证实了以下假设：向膀胱内注入氙可作为膀胱壁通透性和血流的指标。
