the estrogen-responsive ring finger protein (Efp)- gene, one of estrogen receptor (ER) target genes, is considered to be essential for estrogen-dependent cell proliferation. to understand the estrogenic action on ovarian cancer, we studied the relationships between Efp and ERs expressions and the correlations of Efp expression with clinicopathological parameters in epithelial ovarian cancer. Methods. the protein expressions for Efp, ERα and ERβ were examined by immunoblotting in 12 ovarian cancer cell lines. Efp mRNA expressions were evaluated by quantitative Rt-PCR in 12 ovarian cancer cell lines. A total of 100 surgical specimens diagnosed as epithelial ovarian cancer were examined immunohistochemically using antibodies for Efp, ERα and ERβ . Results. Efp protein was detected in 8 out of 12 cell lines. In Efp protein-positive cell lines, Efp mRNA was expressed higher than that in negative (P = 0.021). All of the Efp protein-positive cell lines simultaneously expressed either ERα or ERβ protein. By immunohistochemical staining, Efp immunoreactivity was detected in 63 out of 100 ovarian cancer specimens and positive signals were in the cytoplasm of carcinoma cells. there were significant correlations between Efp and ERα , ERβ immunoreactivity (Efp and ERα , P = 0.022; Efp and ERβ , P = 0.032). Efp expression was significantly higher in a subgroup with serous adenocarcinoma (P = 0.010) and with advanced disease (P = 0.026). No significant relationship was detected between Efp immunoreactivity and overall survival. Conclusion. the expression of Efp was detected in human epithelial ovarian cancer and high expression of Efp was correlated with advanced disease and serous adenocarcinoma, and ERs status.

本文对一台直喷式柴油机燃烧过程的直接与纹影照像进行了研究。并用两者的对比和缸内压力测量来对混合特性、着火与燃烧过程做了分析,还对各种缸内空气运动所导致的不同燃烧特性也进行了观察。看来,喷射在燃烧室壁上的燃油雾注模型与缸内空气运动相配合似乎对混合过程具有影响。观察了燃油雾注的发展过程,并同某些理论计算做了比较。对在预混合与扩散燃烧期间,紊流对燃烧的作用有了认识,尤其是涡流对扩散燃烧期的影响也得到了进一步的证实。

有机磷农药(OP农药)已被广泛使用,目前在日本注册的就有40余种。因此,研究作物中有机磷农药多成份残留分析的方法,是日常必不可少的工作。常用的分析方法是用活性炭柱层析进行提纯,但这种方法耗时长,而且对植物色素和其他干扰物未必都能彻底除去。在氨基甲酸酯分析中,笔者发现了一种由NH_4Cl和H_3PO_4组成的凝结剂对作物萃取物的提纯具有理想的效果。目前,配备火焰光度检测器(FPD)、氮磷检测器(NPD)或电子捕获检测器(ECD)的毛细管柱气相色谱法已应用于各种有机磷农药的检测。
