Hemal Node of Egyptian Water Buffalos (Bos Bubalus): It’s Role in Erythrophagocytosis

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.
