Histological study of granulocytic series in the bone marrow of adult goat (Caprus Hircus)

Abstract

Objectives The aim of this research is to identify and evaluate the cellular granulocytic series of bone marrow in goat that aids to diagnose bone marrow from a variety of clinical disorders in the field of medicine.
Methods Five adult goats were used in this research. These animals are obtained from the Animal’s Field in the College of Veterinary Medicine, University of Al-Fallujah.
Results The first indication of the granulocytic series begins from Myeloblast, which possesses eccentric, round or oval nucleus that surrounded by a rim of cytoplasm. The smaller nucleus leads to identify the Promyelocyte. The cytoplasm of Promyelocyte is very light. Definitive granulations appear within the cytoplasm of Myelocyte, which has round to oval nucleus. The elongation of the nucleus indicates the Metamyelocyte. This cell shows the neutrophilic, eosinophilic and basophilic Metamyelocyte. A large segment of a circle or twisted nucleus represent the Band cell. The last stage of granulocytic series is the segmented cell, which is illustrated by segmented neutrophil, eosinophils, and basophils.
Conclusion The developmental process of granulocytopioesis series of bone marrow in goat encompasses a lineage of successive morphological alterations involves nuclear and cytoplasmic changes as well as granule transformation resulting in the production of granulocytes.
