| Abstract: | The phagocytic function of the mononuclear phagocytic system (MPS) in normal sapphire mink and in sapphire mink affected with experimental Aleutian disease was compared. Clearance from blood of carbon particles or 125I-labeled microaggregated human serum albumin, and subsequent measurement of radioactivity in phagocytic organs indicated profound MPS blockade in mink affected with advanced Aleutian disease. In contrast, MPS activity in mink in the early stage of the disease was comparable to that of normal mink. It is suggested that the MPS blockade may be responsible for some pathologic changes in Aleutian disease. |
