The so-called nucleated thrombocytes of the domestic fowl (and mallard) were analyzed intravitally by use of phase- and interference-contrast microscopy with regard to their morphology and functional state, and in comparison to other avian blood cells and mammalian blood platelets. Since nucleated thrombocytoid cells of birds do not differ in size from white blood cells, they are automatically included in differential cell counts. They can easily be confused with other white blood cells and even with erythrocyte ghosts, which also appear to be hemostatically active elements. However, the nucleated thrombocytoid cells displayed a characteristic, definite morphology. The platelet-like spreading process and elongation of aging cells in vitro to spindle forms deserve special attention. A technique of counting live avian blood cells was used to determine their values in chickens of different sexes and ages.
利用相差显微镜和干涉对比显微镜对家禽（和绿头鸭）的所谓有核血小板进行了活体分析，研究其形态和功能状态，并与其他禽类血细胞和哺乳动物血小板进行比较。由于鸟类的有核血小板样细胞在大小上与白细胞没有差异，它们会自动被纳入细胞分类计数中。它们很容易与其他白细胞甚至红细胞影相混淆，而红细胞影似乎也是具有止血活性的成分。然而，有核血小板样细胞呈现出一种特征性的、明确的形态。血小板样的铺展过程以及衰老细胞在体外伸长为纺锤形的现象值得特别关注。采用一种计数活禽血细胞的技术来确定不同性别和年龄鸡的血细胞值。
