| Abstract: | The author studied the capacity of granulocytes and reticular cells of rat bone marrow to phagocytize mouse red blood cells in the action of opsonins against them. A comparative assessment of phagocytosis of fresh and formaldehyde-treated mouse red blood cells was conducted. A moderate phagocytosis observed with the use of fresh erythrocytes and immune noninactivated rat serum was less pronounced when inactivated serum was used. No phagocytosis occurred with rat nonimmune serum. On the contrary, when formaldehyde-treated erythrocytes were used with the same sera phagocytosis was much stronger. |
