Megakaryocytes of the Spleen in Experimental Amyloidosis and Effect of Red Wine.

Amyloidosis was modeled in young mice by administration of aqueous solution of soy cream substitute and then, amyloidogenesis was corrected by oral administration of dry red wine. In mice with amyloidosis, the area of megakaryocytes decreased by 1.69 times, the relative content of oxyphilic forms of megakaryocytes increased by 4.33 times, and ploidy did not change in comparison with the corresponding parameters in intact mice. Administration of red dry grape wine against the background of formation of systemic amyloidosis changed the reaction of megakaryocytes: the content of polychromatophilic forms was comparable to the level of intact control, the content of oxyphilic forms decreased by 3.11 times, the RNA and DNA content in megakaryocyte nuclei decreased proportionally, and the ploidy decreased. Thus, red grape wine reduced the response of the megakaryocyte genome to the external supply of amyloidogenic substance.
