Ultrastructural Study of the Outer Cortex, Deep Cortex and Medulla of Mesenteric Lymph Node in Adult Goats

Abstract

Background: A mesenteric lymph node in the sub pyloric region which is the longest among all mesenteric lymph nodes in adult goats was identified for study under the scanning electron microscope. Methods: The outer cortical, deep cortical and medullary parenchyma of the collected lymph nodes was thoroughly screened under VEGA3 TESCAN. The outer cortical parenchyma revealed T lymphocytes, B lymphocytes, Sinus Lining Cells (SLC) and Sinus Reticular Cells (SRC) at a magnification of 9600x. The deep cortical parenchyma revealed Reticular cells, T lymphocytes and Interdigitating cells (IDC) at 8000x magnification.Result: The medullary parenchyma revealed T lymphocytes, B lymphocytes, Sinus Lining Cells (SLC), Fibrous Reticular Cells (FRC) and medullary sinuses at a magnification of 8500x. Plasma cells and lymphocytes also remained in the sinus. The morphology and relations of the cells observed were recorded.
