retropharyngeal lymph nodes

Distribution of S-100 positive dendritic cells in retropharyngeal lymph nodes of dairy cow

乳牛咽后淋巴结内S-100阳性树突状细胞的分布

Background : Nasopharyngeal carcinoma is a commonly seen virulent malignancy of head and neck tumors in the southern part of China and with a high incidence of metastasis of retropharyngeal lymph nodes .

背景：鼻咽癌是中国华南地区常见的恶性肿瘤，其咽后淋巴结转移发生率高。

To observe the distribution of dendritic cells ( DCs ) in retropharyngeal lymph nodes of dairy cow , lymph nodes were obtained from 10 healthy dairy cow . Paraffin sections were prepared as usual , and immunohistochemistry staining was conducted with S-100 protein as a marker of DCs .

采取10头健康乳牛的咽后淋巴结，按常规制备石蜡切片，用兔抗牛S-100多克隆抗体进行免疫组织化学染色，观察了健康乳牛咽后淋巴结内树突状细胞（DC）的分布。
