Each male ratwas paired with 2 female rats in proestrus when administration terminated. Femalerats were examined the next morning for the presence of sperm in vaginal smears andunderwent a cesarean section on day 13 of gestation. Then the reproductive indiceswere calculated as follows: copulation index, pregnancy index, and fertility index,which can evaluate male fertility directly. The sperm motility and morphology wereevaluated by computer-assisted sperm analysis, moreover, the caudaepididymal sperm ultramicrostructure were analyzed by transmission electronmicroscope, which can evaluate the influence on sperm maturation bydutasteride ; sperm survival rate was assessed by SYBR-14 and propidium iodidefluorescent staining; serumal dihydrotestosterone and testosterone of ratswere detected by enzyme-labeled immunoassay, which can evaluate the effecton androgenic levels; the weights of testes and epididymides, were determined byprecise electronic balance; histological examination of above tissues were evaluatedby HE staining and TEM, which can evaluate treatment on histology of reproductiveorgans by dutasteride.

The study about the flux and index of gamma-ray loud blazars show:(1)there is significant correlation between the luminosities in gamma-ray and VLBI radio energy band;(2)there are strong anticorrelarions among the observed indices of soft X-ray, hard X-ray and gamma-ray. For the FSRQs, the whole X-ray emission was contributed by synchrotron self-Compton emission, for the HBLs, the X-ray emission was dominated by synchrotron emission while the soft X-ray emission is dominated by synchrotron emission and the SSC emission dominate the hard X-ray energy band for LBLs;(3) there are strong radio-radio and radio-optical flux correlations for the quasar 3C 273. The higher frequency emission leads those in lower frequency. The multi-band complex indices strongly correlated with the high frequency flux which implies that the object is becoming bright when the energy spectrum is harden.

通过对γ噪Blazar天体的谱指数、流量的相关研究，发现（1）51个样本blazar的γ射线光度与VLBI光度之间存在显著相关；（2）软X、硬X以及γ波段的观测谱指数之间存在较强的反相关，对FSRQs，无论是硬X射线还是软X射线的辐射都是逆康普顿辐射的贡献，而对于HBLs来说，则是同步辐射的贡献，对LBLs，在软X射线波段以同步辐射贡献为主，在硬X射线能区以逆康普顿贡献为主；（3）3C 273的射电各个波段以及光学之间存在强相关，高频辐射一直领先低频辐射，3C 273的多波段复合谱指数和高频流量之间存在强的反相关，意味着当能谱变硬时对象变亮。
