    An Investigation into Hematoprotective and Antioxidant Effects of Salvia virgata Jacq. Upon Cyclophosphamide-Induced Toxicity
    (2022) Sahin, İlknur Kulcanay
    The present study aims to investigate hematoprotective and antioxidant effects of Salvia virgata (SV) on Cyclophosphamide (CP)-induced toxicity. The rats were divided into 6 groups of 7 members each. These were the Control group, CP Group (150 mg kg-1), 100 and 200 mg kg-1 SV Groups, and CP+100 and CP+200 mg kg-1 SV Groups. All the rats were sacrificed to harvest their blood and bone marrow samples the day after final injections. While some of the blood samples were used for leukocyte and platelet count, the others were used to determine the levels of total antioxidant capacity (TAC), malondialdehyde (MDA), total oxidant status (TOS), glutathione (GSH), and oxidative stress index (OSI). While a decrease was observed in the leukocyte, platelet and bone-marrow nucleated cell counts of the group given CP, apart from a decline in GSH and TAC levels, the MDA and TOC levels of the rats in this group showed an increase. In contrast, CP-induced oxidative stress and myelosuppression reversed in the combined SV Groups (CP+100 and 200 mg kg-1 of SV Groups), although the reversal in the latter group was of more significance. Our experimental results have shown that SV may exert antioxidant and cytoprotective effects upon CP-related peripheral blood and bone marrow toxicities.

    The protective effects of Selenium and Boron against Cyclophosphamide-induced bone marrow and blood toxicity: An in vivo study

    Thanks to their antioxidant, anti-apoptotic, anti-lipid peroxidative, and immune-boosting properties, Boron (B) and Selenium (Se) are essential trace elements for the human body. This study aims to compare the myeloid protective potentials of Se and B in Cyclophosphamide (CP)-induced bone-marrow and haematological toxicity in experimental rats considering that the myelotoxic property of this anti-cancer drug limits its use. We hypothesized that selenium has a better protective effect than boron in preventing the toxic effects of CP on bone marrow and blood cells. 1.5 mg/kg of Se and 20 mg/kg of B, which are the most frequently used optimal doses of these trace elements, were given to the animals intraperitoneally throughout the experiment. 200 mg/kg of CP was administered only on the 4th day. The animals were sacrificed to take the blood and bone marrow samples to be stored for hematological evaluations. The CP administration significantly decreased leukocyte (WBC), thrombocyte (PLT), erythrocytes (RBC), and bone marrow nucleated cell counts. On the other hand, they increased in significant amounts in the groups given Se and B along with CP when compared to those given only CP. However, Se proved to be more protective than B in preventing CP-induced bone marrow and hematologic toxicity despite not achieving statistical significance. It was, therefore, concluded that the doses used in this experiment were successful in protecting against CP-induced damage to the bone marrow and CP-related hematological toxicity.
