Results HE staining showed that sulindac could inhibit the growth of tumor cells, with the morphological presentations as apoptosis and necrosis including pyknosis, karyorrhexis and chromatin crescent formation, etc. By electron microscopy, cells also had apoptotic characteristics including chromatin crescent formation and apoptotic body. Immunohistochemistry and Western-blot assay results showed that 48 hours after sulindac administration, the expression of NF-κB, bcl-2 and bax gradually decreased, while the level of bax protein gradually increased, in a dose dependence manner.

结果 苏木精－伊红染色检测结果显示舒林酸抑制肿瘤细胞生长，肿瘤细胞出现核固缩、核碎裂、染色质边集等凋亡及坏死的形态学表现；电镜下可看到染色质边集、凋亡小体；免疫组化、Western-blot结果显示舒林酸作用48 h后人胃癌SGC-7901细胞NF-κB、bcl-2表达逐渐下降，bax表达逐渐上升，具有剂量依赖性。

Results: Of all the semen samples, 8 were HCMV positive, 4 HSV-Ⅱ positive, but none were both HCMV and HSV-Ⅱ positive. HCMV late antigens were positively and HCMV early antigens negatively expressed in the spermatogenic cells of the 8 HCMV positive cases. In the 4 HSV-Ⅱ positive cases, 3 were positively and 1 weakly positively expressed. In the semen of the 12 positive cases were found large numbers of immature spermatogenic cells, with different manifestations of apoptosis, such as chromatin pycnosis, vacuoles, damaged nuclear membrane, and apoptotic bodies, but without virus infection-induced specific morphological alteration.

结果：83例精液样本PCR检测HCMV阳性8例，HSV-Ⅱ阳性4例，未发现2种病毒同时阳性病例。8例HCMV阳性病例ICC标记生精细胞HCMV晚期抗原均见阳性表达，HCMV早期抗原均为阴性表达；4例HSV-Ⅱ阳性病例ICC标记生精细胞3例阳性表达，1例弱阳性。12例病毒阳性病例均发现较多未成熟生精细胞，并有不同程度的核染色质固缩、出现空泡、核膜破损、核崩解、凋亡小体等凋亡现象，但未能找到病毒感染的特异性形态学改变。
