Cyclophosphamide administration for limitation of carcinosarcoma Walker 256 growth in rats aggravates the paraneoplastic ultractructural disturbances in the liver

Abstract

The signs of lysis and necrobiosis intensification in parenchyma and stroma cells were revealed in the liver of carcinosarcoma Walker 256-bearing rats at the 7th day after cyclophosphamide administration. Compensatory and adaptive reconstructions and apoptosis were noted in part of cell as a result of cyclophosphamide cytostatic effect. Combined effects of paraneoplastic factors and cyclophosphamide enhance subcellular sinusoidal obstructive syndrome manifestation caused by cyclophosphamide. Hepatocytes ultrastructural features reflect the functional liver response via triggering of detoxification mechanisms in hepatocytes with extensive smooth endoplasmatic reticulum.
