CD68巨噬细胞在腰椎间盘突出组织中的分布及其意义

目的:研究CD68巨噬细胞在不同类型腰椎间盘突出组织中的分布及其意义。方法:应用免疫组织化学方法检测40例(男27例,女13例)退变腰椎间盘和8例(男3例,女5例)特发性脊柱侧凸腰椎间盘髓核组织中CD68的表达。将获得的数据进行统计学分析。结果:腰椎间盘突出破裂型组和未破裂型组CD68表达阳性分别为18例,13例。8例特发性脊柱侧凸腰椎间盘组织中CD68阳性表达1例。结论:CD68巨噬细胞参与了腰椎间盘突出症的发病,但与突出严重程度无关。     

Plasminogen activator activity in human endometrial carcinoma

Plasminogen activator activity (PAA) has been proposed as an indicator of aggressiveness of tumors and has been shown to be hormonally modulated. To test this hypotheses in human endometrial carcinoma, tumor explants were assayed for PAA secretion and the results correlated with histopathologic criteria of aggressiveness. The effect of medroxyprogesterone acetate (MPA) on PAA secretion was also investigated. Lower levels of PAA were found to be associated with tumors displaying aggressive tendencies. MPA generally decreased PAA secretion. No apparent correlation was found between estrogen or progesterone receptor concentrations and PAA levels.     

Recurrent ovarian carcinoma: retreatment utilizing combination chemotherapy including cis-diamminedichloroplatinum in patients previously responding to this agent

Eleven women with advanced ovarian cancer treated postoperatively with combination chemotherapy (cytoxan, hexamethylmelamine, Adriamycin, and cis-platinum) had disease-free intervals of 5 to 46 months (mean: 22 months) and subsequently developed recurrent carcinoma. Each patient was then retreated with combination chemotherapy which included cis-platinum. There was a 72% response rate to retreatment (36% complete, 36% partial). These overall and complete remission rates are comparable to those of platinum-based combination chemotherapy in patients without prior treatment. Those patients who responded to retreatment had a significantly longer mean survival rate than those who did not.     

鼻息肉组织中炎性细胞的病理学意义

研究鼻息肉组织中炎性细胞的病理意义。方法对１０例正常鼻粘膜和２４例鼻息肉组织行免疫组化及ＭＧＧ染色以观察嗜酸性粒细胞,单核细胞,巨噬细胞在组织中的分布程度,结果：鼻息肉组织中嗜酸性粒细胞,ＣＤ６８阳性巨噬细胞和单核细胞显著增加。结论：鼻息肉的发生与炎性细胞的浸润,活化密切相关,药物治疗应是鼻息肉病治疗中的一个重要方面。
