银白前口虫Frontonia leucas Ehrenberg切割口器再生研究

Oral Apparatus Regeneration of Frontonia leucas (Ehrenberg)

观察银白前口虫 Frontonia leucas Ehrenberg切割去除口器的再生过程,发现靠近口后缝的纤毛条索对带核的无口器断片再生口器起重要作用。银白前口虫在口器再生过程中与皮膜上老纤毛结构相关,在口后缝前部的左边若干纤毛条索从产生新基体开始至分化成咽膜和口洼。

The stomatogenesis is observed in the regeneration process on the fragments ofexcied Frontonia leucas. Some old kinety of cortex are relevant to stomatogenesis.The ciliary streaks nearby front-left of postoral sutura play an important roleto oral apparatus regeneration in fragment with macronucleus. Developed fromthese streaks, differentiated into pharyngeal membranelles and buccal fosse, andconnected with regenerated vestibular kinety nearby right of postoral sutura,New primordium forms new oral apparatus.
