肿瘤特异性生长因子(Tumorspecificgrowthfactor,TSGF)是恶性肿瘤形成及生长时促进肿瘤及周边毛细血管大量增殖的因子,在恶性肿瘤形成时释放入血,对恶性肿瘤具有特异性。测定血清中TSGF含量对恶性肿瘤的诊断、疗效监测可能具有较为重要的意义。本文对30例肺癌患者治疗前后TSGF进行了测定。材料与方法1 实验对象 正常对照组18例,男性13例,女性5例,年龄20~66岁,为健康体检者。肺癌组30例,男性21例,女性9例,年龄42~72岁,均经病理证实确诊。分别于治疗前及治疗后1…  相似文献

用神经组化和免疫组化方法,系统地观察了32例新儿气管、支气管的神经分布,并探讨其特点。实验显示:气管、支气管受胆碱能(Cholinergic)肾上腺素能(Adrenergic)和血管活性肠肽能(VIP-ergic)神经支配。前两种神经分布气管直至终末细支气管;VIP-ergic神经见于气管、支气管平滑肌和腺体、且比Adrenergic神经纤维丰富。Cholinergic、Adrenergic、VIP-ergic神经末梢均支配到气管、支气管的血管壁外膜或外、中膜交界处,在所有材料,Cholinergic神经节得到证实,但未见Adrenergic、VIP-ergic神经节。  相似文献

15例恶性肿瘤患者在进行骨髓移植(异基因骨髓移植3例、自体骨髓移植6例和混合骨髓移植6例)时应用分次全身照射技术。分次照射方案:8~15MVX线总剂量800~1000cGy,每天2次,共计2天,每次照射间隔时间为6h;剂量率5.98~6.32cGy/min,平均剂量率为6.6cGy/min;肺遮挡后平均剂量为600cGy,胸壁补充9MeVβ线200cGy。随防结果∶3例移植失败(异基因骨髓移植1例、混合骨髓移植2例),1例慢粒急变行自体骨髓移植后10个月因肿瘤复发而死亡,其余11例均无瘤生存;无1例出现放射性损伤。结果提示采用分次照射技术可以提高疗效、减少并发症的发生。  相似文献
