Lastly, based on analysis on phylogentic relationships among 39 ciliates combined with their main morphologic characters, some conclusion were drawn: 1 the monophyly of the peritrichs was strongly supported, and its subclass rank in the class Oligohymenophorea is reasonable; 2 the genus Epistylis might not be monophyletic, and the peristomial area, especially the peristomial lip, might be an important phylogenetic character within the genus Epistylis; 3 the taxonomic rank of the genus Carchesium and the genus Campanella were suggested to be adjusted; 4 Opisthonecta probably diverged from peritrichs with stalks; 5 the phylogenetic tree of peritrichs was reconstructed based on the molecular information inferred from SSrRNA gene sequences and the morphology.

测定了6科8属13种缘毛类纤毛虫的SSrDNA序列，将构建的最大简约树和邻接树与形态学相结合，分析得出：1）缘毛类纤毛虫是单系的，其分类地位是隶属于纤毛门寡膜纲缘毛亚纲：2）指出累枝虫属可能不是单系的，口围区是累枝虫属中重要的系统发育特征；3）建议调整独缩虫和聚钟虫属的分类地位；4）得出后游虫可能是由有柄缘毛类进化而来的类群；5）基于缘毛类反口区结构和SSrRNA基因序列提供的信息重建了缘毛类纤毛虫的系统发育树。

The ciliates were always ideal materials in the studies of the structure and function of cytoskeleton and its cell control and adjustment, for they have many kinds of cytoskeletons with complexity and they could be easily cultured and handled.

由于原生动物纤毛虫具有多种复杂的细胞骨架结构，加之其材料培养和处理的优点，一直被作为研究细胞骨架结构与功能及其细胞调控的理想材料。20世纪80年代初，许多学者应用蛋白银染色方法和超微结构方法，显示了纤毛虫细胞皮层中以纤毛基体作为主成分的骨架结构，探讨了纤毛虫皮层纤毛器的形态、形态发生及其结构形成机理，在国内外原生动物细胞学领域成为主流。20世纪90年代起，先后应用非离子去垢剂处理和扫描电镜相结合的方法、稳定保存微管结构的透射电镜术，微管蛋白的抗体标记及其免疫荧光技术及相关的生化与分子生物学等方法显示纤毛虫的微管胞器及其微管蛋白组分，探索微管胞器的形态、功能及其微管装配机理，积累了较多的资料，取得了重要的进展。
