Methods: The coiled shapes of Trichinella isolated ML were observed under microscopes, then the lengths and widths of ML encystment ( encysted index) were measured at random by micrometer. 方法:镜下观察旋毛虫幼虫卷曲状态,用测微尺随机测量囊包长、宽。
Conclusions: The shapes and indexes of Trichinella isolated ML encystment from different hosts and areas were difference, but they were not proofs to identified Trichinella isolate. 结论:大理不同来源的旋毛虫幼虫囊包形态存在一定差别,但不是旋毛虫种株鉴定的依据。
The encystment and excystment often occurs in ciliates. In the meantime, the cell structures go the different differentiation and recombination. A series of physiological and biochemical changes occur in the cell. 纤毛虫中经常发生形成包囊和脱包囊的过程,期间,细胞结构经历了不同水平的分化和重组,细胞内发生了一系列生理生化变化。
Some researches show that ciliate will differentiate and regulate itself in a way different from the vegetative cell during encystment and excystment, which makes the resting cell become a special study model. 有研究表明,纤毛虫在形成包囊和脱包囊过程中,细胞会经历不同于营养细胞的分化和调控过程,这使得休眠包囊成为一种不同于营养细胞的研究样本。
