The histogensis of extramammary Paget's disease has not been solved and remained controversial. Eight cases of extramammary Paget's disease of geni-tocrural region were investigated by alcian blue and PAS stain and immunoreaction of anti-CEA and anti-keratin. It was found that the pattern and intensity of alcian blue, PAS staining were identical for Paget cells and secretory cells of apocrine sweat gland; and CEA immunoreactivity was uniformly observed in both Paget cells and eccrine sweat gland. The keratin immunoreaction was positive in keratinocytes, apocrine and eccrine sweat gland, whereas Paget cells were negative. These results suggested that Paget cells of extramammary Paget's disease could be derived from multipotential epidermal germ cells. 相似文献

目的:观察植物神经在中医寒热不同证型中的机能状态。方法:用高压液相色谱法测定人血CA、HVA、5-HT;用紫外分光光度法测定红细胞膜上AchE活性。结果:虚热证组CA等含量高于正常组和虚寒组(P<0.01)。虚寒证组RBC膜上AchE活性高于正常组(P<0.05).虚热组低于正常组(P<0.05)。结论:交感神经和副交感神经在中医寒热各证型中的机能状态不同。 相似文献

胸腺激素在调节机体免疫功能,特别是在治疗免疫缺陷病和与免疫失调有关的疾病中的作用,早已被国内外的学者所注意,并在实验和临床工作的观察中获得了令人满意的结果。本试验的目的在于观察小剂量胸腺肽辅助治疗小细胞未分化型肺癌后,患者的免疫功能和临床疗效。列入本实验的患者,均经组织学确诊。实验分为:实验组(胸腺肽辅助治疗组)和对照组(单纯化疗组)。化疗采用COM联合化疗方案,实验组在化疗的同时辅用猪胸腺肽,肌注12mg,每周3次。于化疗前、诱导化疗后及局部放疗后,分别计数总T细胞和E玫瑰花的百分数。临床疗效则以完全缓解、部分缓 相似文献
