Gastric mucosa was removed from five dogs and allowed to regenerate. Serial scintiscans after administration of 99mTc pertechnetate revealed gradual increase in gastric radioactivity, so that by 4 weeks it appeared as intense as preoperatively. By this means it was possible to follow the progress of gastric mucosal regeneration. The authors suggest that serial 99mTc scintiscanning might prove useful in evaluating the hypothesis that Barrett esophagus is due to replacement of esophageal squamous epithelium by gastric columnar epithelium.
从五只狗身上取下胃黏膜，使其再生。给予高锝[99mTc]酸盐后进行系列闪烁扫描，结果显示胃放射性逐渐增加，到4周时，其放射性强度与术前相当。通过这种方法可以追踪胃黏膜再生的进程。作者认为，系列99mTc闪烁扫描可能有助于评估巴雷特食管是由于胃柱状上皮取代食管鳞状上皮这一假说。
