This study was conducted to investigate the effect of different doses injection of human chorionic gonadotropin(HCG)hormone on fecundity and serum sex hormones(FSH,LH,estrogen(E2),progesterone(P4),testosterone(T))of African catfish(Clarias gariepinus).African catfish spawners were intermuscularly injected with different doses of HCG(500,1500,3000,6000 IU/kg female),and group is not injected as a control;males were injected at half the female *** results showed that,fish group injected by 6000 IU HCG/kg female had the highest gonadsomatic index,absolute fecundity and relative fecundity,while,the lowest value of absolute fecundity and relative fecundity were recorded with 500 IU HCG/kg *** group injected with the highest amount of HCG(6000 IU/kg female)recorded the lowest value from egg diameter,while the highest egg diameter was observed in 500 IU HCG/kg *** females,the group injected with 6000 IU HCG/kg female reflected the lowest level of FSH and the highest level of LH and the highest level of P4 compared to other *** of T recorded the highest level with 1500 IU HCG/kg *** control group reflected the highest level of FSH and E2,while the control group reflected the lowest level of T and P4 *** males,serum FSH,LH,P4 and E2 in male groups injected with HCG were relatively higher than those recorded in the control *** highest level of T was recorded in treatment injected with the highest dose of HCG and decreased in other treatments until recorded the lowest level of T in the control *** was observed,HCG hormone has successfully and accelerate induced spawning in African catfish(Clarias gariepinus)and increased in reproductive performance with the increase in HCG dosage and as compared to group not injected.

AIM:To assess the effectiveness of hepatitis B virus(HBV) vaccination program among fully vaccinated ***:A national community based crosssectional study was carried out in 6 governorates representing Egypt. A total of 3600 children aged from 9 mo to 16 years who were fully vaccinated with HBV vaccine during infancy were recruited. Face to face interviews were carried out and sera were evaluated for hepatitis B surface antigen(HBsA g),anti-HBV core antibodies(total) and quantitative detection of hepatitis B surface antibody using enzyme linked immunoassays techniques. Samples positive to HBs Ag/anti-HBV core antibodies were subjected to quantitative HBV-DNA detection by real time polymerase chain reaction with 3.8 IU/L detection limit. RESULTS:Sero-protection was detected among 2059 children(57.2%) with geometric mean titers 75.4 ± 3.6 IU/L compared to 3.1 ± 2.1 IU/L among nonseroprotected children. Multivariate logistic analysis revealed that older age and female gender were the significant predicting variables for having non seroprotective level,with adjusted odds ratio 3.3,9.1and 14.2 among children aged 5 to 0.05. C ON C LU S I ON :T he E gy pt ian c ompuls or y H B V vaccination program provides adequate protection. Occult HBV infection exists among apparently healthy vaccinated children. Adherence to infection control measures is mandatory.

本文评估了公共部门高级官员认为的新公共管理(NPM)式改革对欧洲国家的影响。通过使用在二十个欧洲国家/地区进行的行政调查数据,我们研究了新公共管理的五项关键改革(组织精简、机构化、外包、顾客导向和弹性化雇佣的实践)与公共部门绩效的四个维度(成本效率、服务质量、政策的连贯与协调和平等获得服务的机会)之间的关系。通过建立结构方程模型,我们发现,将服务使用者视为客户以及弹性化雇佣均与改善全部四个绩效维度之间呈正相关的关系。外包和机构精简,二者都和提高效率成正比关系,但是服务质量的下降也会伴随机构精简而来。创建自治机构和绩效之间并无关系。这表明,决策者在对公共部门进行现代化改革时,公共组织内部的管理性改革应优先于结构性改革。
