| 摘 要： | 目的分析颅咽管瘤钙化灶的元素组成及微观结构,探索不同程度钙化间的区别。方法筛选50例颅咽管瘤病例,从肿瘤标本中分离出钙化斑块进行X-线衍射分析及X-线能量色散谱分析。结果 所有钙化斑块均由羟基磷灰石晶体及一些非晶态物质构成,钙化斑块中主要含有钙、磷、碳、氧4种元素,钙、磷、碳3种元素的百分含量在不同钙化程度的分组间具有显著差异(P<0.05),其中钙、磷元素含量与钙化程度呈正相关(rp分别为0.745和0.778,P<0.01),碳元素含量与钙化程度呈负相关(rp=-0.526,P<0.01)。结论不同钙化程度的钙化斑块中钙、磷、碳3种元素的含量不同,3种元素含量的不同影响钙化斑块的钙化程度。

| Abstract: | Objective To analyze the element composition and mircostructure of the calcific focus in craniopharyngiomas for exploring the difference between different degrees of calcification.Methods Specimens of 50 patients with craniopharyngioma were selected,from which calcified plaque were isolated for X-ray diffraction and energy dispersive X-ray spectral analyses.Results All of the calcified plaques in the craniopharyngioma were composed of hydroxyapatite crystal and some amorphous substances.The major elements o... |
