Abstract:
Objective: To explore the protective effects of tannins in Sanguisorba Radix (TSR) on myelosuppression mice induced by cyclophosphamide (CTX). Methods: TSR was ig given at the dose of 20 mg/kg for 10 d after ip administration of CTX (200 mg/kg). Results: TSR could significantly increase the numbers of white blood cells, red blood cells, and platelets of myelosuppression in mice. And it could accelerate bone marrow haemopoietic stem/progenitor cells (HSPCs) in myelosuppression mice and enhance cell proliferation by promoting cell cycles from G0/G1 phase to access into S and G2/M phases, then the reduced number of HSPCs induced by CTX was reversed. Moreover, TSR could increase the mRNA and protein expression levels of O(6)-methylguanine-DNA methyltransferase (MGMT) in HSPCs of myelosuppression mice. Conclsion: TSR has a protective function against CTX-induced myelosuppression. The mechanism might be related to protecting hematopoietic stem cells of bone marrow, stimulating hematopoiesis recovery, as well as preventing the apoptosis of hematopoietic stem cells induced by CTX. © 2014 Tianjin Press of Chinese Herbal Medicines.
