The alveoli of the lungs of 2 aborted foals contained elongated, dense bodies when examined histologically and by transmission and scanning electron microscopy. By light microscopy, the bodies (10 to 40 micrometers in size) stained intensely with the Gram stain, and up to 10 were present within an alveolus. Electron microscopy determined that such bodies were not cellular in origin but appeared to be a congealed fluid product composed of layers of fibrillar-like material. From the human literature, it was concluded that these intraalveolar bodies were probably congealed amniotic fluid.
对2匹流产马驹的肺脏肺泡进行组织学检查以及透射和扫描电子显微镜检查时，发现其中含有细长的致密小体。通过光学显微镜观察，这些小体（大小为10至40微米）经革兰氏染色后着色很深，每个肺泡内最多可有10个。电子显微镜检查确定，此类小体并非细胞源性，而是似乎由纤维状物质层组成的凝固液体产物。根据人类文献得出结论，这些肺泡内小体可能是凝固的羊水。
