Abstract
A single dose of IMUNOR®, a low-molecular-weight immunodulator prepared from disintegrated and ultrafiltered pig leukocytes, was found to enhance recovery of murine pool of hemopoietic progenitor cells for granulocytes and macrophages damaged by a single injection of cytotoxic drugs 5-fluorouracil or cisplatin. The best results were obtained after the treatment with IMUNOR® on days 3 or 4 after the injection of 5-fluorouracil or cisplatin. These results together with previous findings obtained in our laboratory suggest that IMUNOR® has the potential to become a part of treatment schemes in oncological practice aimed at alleviation of myelosuppression evoked by cytotoxic anti-tumor therapy.
