| 摘 要： | 目的 观察不同年龄组正常腮腺α－淀粉酶、溶菌酶的分布、含量及增龄性变化的规律。方法 将５１例腮腺标本分为４个年龄组，用免疫组化的方法标记α－淀粉酶、溶菌酶，观察记录不同年龄组α－淀粉酶、溶菌酶的染色强度。结果 ４个年龄组之间α－淀粉酶、溶菌酶染色阳性率差异有显著性，随着年龄增长，其染色阳性率呈逐渐减低的趋势。结论 ＨＥ切片上染色、形态相似的浆液性腺泡之间，实际在功能上存在着很大的不同。α－淀粉酶、溶菌酶增龄性变化的特点与定量组织学研究结果相符合。

| Abstract: | OBJECTIVE: To investigate the aging changes, the distribution and the content of alpha-amylase, lysozyme in the normal parotid glands. METHODS: Fifty-one specimens of parotid glands with 4 different age groups were studied by immunohistochemical method. The intensity of staining of alpha-amylase, lysozyme was recorded in different age groups. RESULTS: The staining positivity rate of alpha-amylase, lysozyme had striking differences in 4 different age groups and it gradually decreased along with the age increasing. CONCLUSIONS: There are differences among seous acinus which had similar shape and staining in HE slice. The characters of aging changes of alpha-amylase, lysozyme secreted by acinar and intercalated duct cells are conformity with the results of quantitative studies in histology. |
