Abstrakt: We analyzed advantages of the liposomal form of Xymedon (50 and 100 mg/kg) over free Xymedon (in the corresponding doses) in leukopoiesis restoration in rats with Walker-256 carcinoma treated with liposomal combination of doxorubicin (4 mg/kg) and cyclophosphamide (45 mg/kg) (single intravenous injection on day 11 after transplantation of tumor cells). Liposomal and free Xymedon were injected intravenously over 5 days starting from day 11 of the experiment. Changes in leukopoiesis in peripheral blood and myelograms were assessed on days 3 and 7 after chemotherapy. Liposomal Xymedon in both doses (unlike its free form) 2-fold increased the number of lymphocytes on day 3 after chemotherapy in comparison with the level observed after administration of liposomal cytostatics alone. Liposomal Xymedon in a dose of 50 mg/kg (but not 100 mg/kg) promoted the maintenance of monocyte count at the level of intact control on days 3 and 7 after chemotherapy. Liposomal Xymedon in a dose of 50 mg/kg and free Xymedon in a dose of 100 mg/kg equally stimulated the increase in myelocytes content in the bone marrow to the level of intact control on day 3 after chemotherapy, thus promoting restoration of granulocytopoiesis.
