Abstract

The skin of the postero-superior part of the meatus and drum of guinea pigs was treated with enbucrylate and examined via light microscope and electron microscope after three weeks. The squamous epithelium was thickened with extensive rete pegs in the subepithelial space. The epithelial cells were loosely arranged and their nuclei pathologically changed. In the oedematous perimatrix small finger-like epithelial proliferations and activated mesenchymal cells could be seen.

摘要

对豚鼠耳道后上部及鼓膜的皮肤用氰基丙烯酸酯处理,三周后通过光学显微镜和电子显微镜进行检查。鳞状上皮增厚,上皮下间隙有广泛的 rete 钉。上皮细胞排列疏松,细胞核发生病理性改变。在水肿的基质中可见小手指状上皮增生和活化的间充质细胞。
