| 1 | Accelerated ovarian aging in mice by treatment of busulfan and cyclophosphamide显示文摘Busulfan/cyclophosphamide(Bu/Cy) conditioning regimen has been widely used to treat cancer patients,while their effects on major internal organs in females are not fully understood.We treated female mice with Bu/Cy,and examined the histopathology of major internal organs on Day 30 after the treatment.The results show that Bu/Cy treatment affected the ovaries most extensively,while it had less effect on the spleen,lungs,and kidneys,and no effect on the heart,liver,stomach,and pancreas.To better understand the effect of Bu/Cy on the ovaries,we counted follicles,and determined the levels of ovarian steroids.The Bu/Cy-treated mice showed a reduction of primordial and primary follicles(P<0.01) on Day 30 and a marked loss of follicles at all developmental stages(P<0.01) on Day 60.Plasma levels of estradiol and progesterone in Bu/Cy-treated mice decreased by 43.9% and 61.4%,respectively.Thus,there was a gradual process of follicle loss and low estradiol in Bu/Cy-treated mice;this is a profile similar to what is found in women with premature ovarian failure(POF).The Bu/Cy-treated mice may serve as a useful animal model to study the dynamics of follicle loss in women undergoing POF. | Yan JIANG Jing ZHAO Hui-jing QI Xiao-lin LI Shi-rong ZHANG Daniel W.SONG Chi-yang YU Jian-gang GAO | 2013 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2013，14，4： | 3 |
