喉癌的浸润和扩散与喉内微血管和微淋巴管分布密切相关。观察喉内微血管和微淋巴管分布 ,对研究喉癌扩散规律、喉癌术式选择和手术安全边缘界定等都有重要的意义。本文采用酶组织化学染色法 ,观察喉内各部组织微血管和微淋巴管分布的差异 ,借以探讨其临床意义。1 材料与方法新
The invasion and spread of laryngeal carcinoma are closely related to the distribution of microvascular and lymphatic vessels in the throat. To observe the distribution of microvascular and micro-lymphatic vessels in the throat is of great significance for the study of the rule of laryngeal cancer’s proliferation, surgical selection of laryngeal cancer and the definition of surgical margin of safety. In this paper, enzymatic histochemical staining was used to observe the distribution of microvessels and micro-lymphatic vessels in different tissues of larynx to explore the clinical significance. 1 Materials and Methods New
