Lymphocyte subpopulation as well as other hematological properties were compared between arterial and venous bloods of Wistar-Imamichi rats. Lymphocyte subsets were defined with four monoclonal antibodies which were specific to the respective cell surface glycoproteins. Using these monoclonal antibodies, subsets of B lymphocytes, T lymphocytes, helper T lymphocytes, and suppressor and cytotoxic T lymphocytes in the peripheral lymphocytes were identified. The blood samples were taken from aorta abdominalis and venae cava caudalis. The population of these subsets were enumerated by a laser flow-cytometry system. The result showed that there was no significant difference in hematological properties between the arterial and venous blood except in leukocyte count and hemoglobin concentration. The difference in leukocyte counts was thought to depend mainly on the fluctuation of the lymphocyte counts. However, no significant difference was recognized in the proportion of positive cells to each monoclonal antibody. It was concluded that the difference in leukocyte counts found between the arterial and venous bloods of the Wistar-Imamichi rat did not produce any effects on the proportion of the subpopulation in the peripheral lymphocytes, and the lymphocyte subpopulations in both arterial and venous bloods were substantially equivalent to each other.
