Abstract:
Objective To investigate the repeated dose toxicity of doxorubicin liposome injection and doxorubicin injection in rats. Methods Ninety SD rats ( body weight 180-220 g, male:female=1:1 ) were divided into 3 groups (30 rats in each group), and were administered intravenously with physiological saline, doxorubicin liposome injection (1 mg·kg-1 ) and doxorubicin injection ( 1 mg·kg-1 ) , respectively, once every three days for thirteen times. The body weight, blood biochemistry, hematology, organ coefficient and histopathology were analyzed for the overall toxicity assessment. Results The rats administered with doxorubicin liposome injection (1 mg/kg) showed hair loss and skin ulcer, significantly reduced growth of body weight, increased levels of urea nitrogen ( BUN ) , alanine aminotransferase ( ALT ) , blood platelet ( PLT ) , and kidney and heart coefficients, decreased thymus and testicular coefficients, myofibrillar rupture and lysis, and partial loss of cell nuclei, hyaline casts in the renal convoluted tubules, interstitial edema and loss of spermatogenic cells in the testicular tubules. Compared with the doxorubicin liposome injection group, similar abnormal changes were also observed in the doxorubicin injection group, but the hair loss and skin ulcer were milder and the heart and kidney toxicities were severer. Conclusions Compared with doxorubicin injection, the doxorubicin liposome injection causes milder heart and kidney toxicity but more serious skin toxicity.
