Popis: Background. Side effects of antineoplastic agents (especially leukopenia and neutropenia) could be the main limiting factors for efficient treatment. Objective. The research is aimed at the study of myeloprotective capability of biosimilars of granulocyte colony stimulating factor (G-CSF) and granular carbon oral adsorbent C2 in melphalan-induced bone marrow suppression in Guerin carcinoma-grafted rats. Methods. Melphalan at the dose of 5.5 mg/kg was used to promote bone marrow suppression in the Guerin carcinoma grafted rats. To fight myelosuppression, we used filgrastim and its analogue, designed and produced by IEPOR, a recombinant granulocyte colony-stimulating factor (r-GCSF). Carbon granulated enterosorbent C2 was used for enteral sorption therapy (bulk density γ=0.18 g/cm3, diameter of granules 0.15-0.25 mm, BET pore surface – 2162 m2/g). All rats were sacrificed on the 17th day after carcinoma cells inoculation or on the 8th day after Melphalan injection. Results. Alkylating cytostatic agent caused severe leukopenia (by 95.7%), neutropenia (by 73.9%), and thrombocytopenia (by 84.9%) in the experimental rats. Mortality rate was 57%. Filgrastim and enterosorption with carbon oral adsorbent C2 increased the studied indices, but the most prominent results were observed when combination of both factors was used. Studied means did not affect the anti-tumor efficacy of Melphalan alone and in combination. Conclusions. Our results are perspective for further investigation of the efficacy of the combination of carbon oral adsorbents and hematopoietic cytokines in cases of ameliorate anti-cancer chemotherapy side effects, and its implementation into clinics.
