Some functional peculiarities of miracidia hatching from O. felineus eggs have been studied, using scanning electron microscope. The results were compared to the earlier data obtained by the method elaborated for the determination of opisthorchis eggs viability by stimulation of miracidia release in the artificial media. It is concluded that in the course of miracidia hatching the two release-stimulating factors (mechanical and chemical) are mutually complementing each other. First, the egg membrane is deformed, in which the radula of the mollusk host plays an essential role, then the process of chemical activation of the hatching gland is triggered and miracidia motor activity is stimulated. A complex comb-shaped structure of opisthorchis eggs outer membranes is associated with the necessity of long-term eggs survival in the water reservoirs and forms a light delicate carcass preventing the egg from deformation.
利用扫描电子显微镜研究了从猫后睾吸虫卵孵化出的毛蚴的一些功能特性。将结果与早期通过在人工培养基中刺激毛蚴释放来测定后睾吸虫卵活力的方法所获得的数据进行了比较。得出的结论是，在毛蚴孵化过程中，两种释放刺激因素（机械因素和化学因素）相互补充。首先，卵膜发生变形，其中软体动物宿主的齿舌起重要作用，然后触发孵化腺的化学激活过程并刺激毛蚴的运动活性。猫后睾吸虫卵外膜的复杂梳状结构与卵在水库中长期存活的必要性相关，并形成一个轻质精致的外壳以防止卵变形。
