Cuscuta chinensis Ameliorates Immunosuppression and Urotoxic Effect of Cyclophosphamide by Regulating Cytokines - GM-CSF and TNF-Alpha.

PMID 25900435


Cancer is the leading cause of death worldwide. Cyclophosphamide (CTX) is commonly used as anticancer drug which causes toxicity by its reactive metabolites such as acroline and phosphoramide mustard. In this study, Cuscuta chinensis (C. chinensis) (family: Convolvulaceae) was assessed for ability to restore mice against CTX-induced toxicity. Coadministration of C. chinensis extract (10 mg/kg BW, IP, daily) for ten consecutive days reduced CTX-induced (25 mg/kg BW, IP, daily) toxicity. Treatment with C. chinensis extract significantly (p < 0.01) increased the relative organ weight and body weight. Moreover, administration of C. chinensis extract significantly increased bone marrow cellulatity and α-esterase activity in CTX-treated mice which suggested its protective role on the hematopoietic system. The GSH content was drastically reduced by CTX administration in urinary bladder which was enhanced by treatment with C. chinensis extract, indicating that preventing acroline-mediated tissue damage or cell toxicity and also the extract decreased the urinary bladder nitric oxide (NO) level which proves recovery over urinary tract injury associated with CTX treatment. The administration of C. chinensis extract decreased serum urea, creatinine, and bilirubin levels when compared to CTX-alone-treated group. Histopathological analysis of the urinary bladder of CTX-alone-treated group showed necrotic damage whereas the C. chinensis-treated group showed normal bladder architecture. The above data clearly demonstrates chemoprotective role of C. chinensis against CTX-induced toxicities by regulating antioxidant and inflammatory mediators.
