Ultrastructure of 20 cases oral lichen planus was observed. Colloid bodies were found in 4 cases. Morphologically, the colloid bodies could be divided into four types: Mass-filament shape: compound type of mass-filament shape and filament shape of low electronic density; filament shape of low electronic density and filament shape of high electronic density. Among them, the compound type was not reported until this study. Owing to discovery of the compound colloid body, the fact that there is an intermediate stage in the course of formation of the colloid body was more correctly known by the authors. And a model figure which expressed the course of formation of colloid bodies was drawn up. The authors have imagined the nature of colloid body is degeneration of epithelial cells. The result of degeneration is death of the cells.
观察了20例口腔扁平苔藓的超微结构。4例中发现了胶样小体。从形态学上看，胶样小体可分为四种类型：团丝状：低电子密度的团丝状与丝状的复合型；低电子密度丝状与高电子密度丝状。其中，复合型直至本研究才见报道。由于复合胶样小体的发现，作者们对胶样小体形成过程中存在中间阶段这一事实有了更确切的认识。并绘制了表示胶样小体形成过程的模式图。作者们推测胶样小体的本质是上皮细胞的变性。变性的结果是细胞死亡。
