Abstract

Hemal nodes were obtained from 12 clinically healthy male buffalos aged 2-3 years, their average weight is 500-600kg. Electron microscopy revealed macrophages engulfing intact erythrocytes in vacuoles, or only parts of erythrocytes appeared in the vacuoles. Some electron dense material appeared in the erythrocyte as a lysosomal degrada- tion. Also myeline like figures and residual bodies were seen in macrophages cytoplasm. plasma cells were observed to be in close association to the macrophages and both cells make a sort of union in some sites. A number of electron dense bodies with variable shapes and sizes were seen in the cytoplasm of the plasma cells near the nucleus. The findings of this study suggests the occurrence of erythrophagocytosis in buffalo hemal nodes. The main cells responsible for this rule were macrophages may be together with the help of plasma cells. No rule could be recorded for other cells as lymphocytes, mast cells, endothelial cells or reticular cells in erythrophago- cytosis.
