Abstract
Tabular and ultrastructural studies were made of 1, 000 cells, each from the thoracic duct lymph of six adult, clinically normal cats.
Cells of the thoracic duct lymph were morphologically classified by visual inspection at the ultrastructural level and found to consist of 84.9% lymphocytes, 5.7% lymphoid blast cells, 6.7% immature and mature plasmacyte-like cells, 0.2% monocytes, 0.4% mitotic cells, 1.7% granulocytes and 0.3% unclassified agranulocytes.
Quantitative studies of number per cell section and profile size of mitochondria among the different cell types demonstrated that monocytes had smaller (0.068μ2) and more numerous (13.5) mitochondria than any other types of of cells (0.102-0.165μ2 and 4.3-8.6 respectively).
