title: Ring-shaped nuclei in human neutrophilic leukocytes of healthy individuals: evidence of their occurrence and characteristics.
abstract: In our previous work we found the presence of ring-shaped nuclei in circulating neutrophils of healthy individuals whose nuclei were stained only by means of the Feulgen reaction [1]. In our present work, we performed another study on the blood of 52 healthy human donors and stained their blood films with hematoxylin. In all cases, ring-shaped nuclei were revealed. In this series, the number of this type of nuclei was high: 15.61% +/- SD 7.18%. The ring nuclei of healthy humans had thin segments, such as we have previously found by means of Feulgen method.
