  resting cyst
The amount and distribution of the chitin fibrils may play an important role in the properties and functions of the wall of the resting cyst.
      
It represents a strategy against several environmental stresses (such as starvation), which involves a highly gene-regulated cell differentiation process and originates a more resistant, differentiated form or resting cyst.

The cell of Stylonchia mytilus becomes longer and slender and shrinks into a sphere during encystment,its cortical ciliature drops gradually simultaneously.Its two macronuclei change from elliptical to spindle shaped and fuse longitudinally in the middle part of the cell,its four mieronuelei become two in number.At last,it becomes a resting cyst with a spherical macronueleus and two micronuclei enclosed in two layers of cyst membrane.A.unique chromatin reorganization occures in fused macronucleus during encystment:i.e.,the stain of macronuclear chromatin appears deeper in color in the middle and lighter in the peripheral areas at first,and then becomes deeper in the peripheral areas,too.Or,the stain of macronuclear chromatin appears deeper in some parts and lighter in other parts at first,then become deeper in the later parts,too. Afterward,the fused macronucleus divides into two macronuclei and the two micronuclei divide into four.During the process of changing of nuclear apparatus,its cortical eilia-ture arises gradually,and the cell ilself becomes enlongated step by step,and comes out of the cyst at last.

棘尾虫形成包囊时,虫体变得瘦长并团缩成圆球,毛基系也随着逐步脱落,它的两个大核由椭圆形变成纺棰形或长圆形,在虫体中部发生纵向融合,四个小核也减少成为两个,最终成为由两层包囊膜围着的具一个圆形大核和两个小核的休止包囊;棘尾虫脱囊时,融合大核发生特殊的染色质改组现象:即大核染色质变得中部着色深周边着色浅,以后周边的着色程度也变深;或者是大核染色质变得一部分着色深另一部分着色浅,以后另一部分着色也加深。接着,一个融合大核分裂成为两个大核,两个小核也分裂为四个,随着核器的变化,逐渐长出毛基系,虫体同时也逐步拉长,不久便穿膜而出。

The processes of encystment and excystment of the hypotrich ciliate Explotes encysticus were investigated using living organisms, protargol staining, and scanning electron microscopy. During encystment of E. encysticus, the ciliary shafts of the cortical ciliatures were re-sorbed in part or in whole, while the kinetosomes were preserved. In the resting cyst, the dorsal ciliatures remained more or less at their original positions on the cell surface, but the-adoral zone of membranelles (AZM) and the undulating...

The processes of encystment and excystment of the hypotrich ciliate Explotes encysticus were investigated using living organisms, protargol staining, and scanning electron microscopy. During encystment of E. encysticus, the ciliary shafts of the cortical ciliatures were re-sorbed in part or in whole, while the kinetosomes were preserved. In the resting cyst, the dorsal ciliatures remained more or less at their original positions on the cell surface, but the-adoral zone of membranelles (AZM) and the undulating membrane (UM), the fronto-ventral cirri (FVC) and the transverse cirri (TC), the left caudal cirri (LCC) and the right caudal cirri (RCC), ihvaginated successively into the cytoplasm, and converged to each other. During excystment, the mid-dorsal region was the first to escape from the dorsal ostiole, the anterior was the last to free from the cyst wall. The ciliatures under went a process of redif-ferentiation during which the new ciliary shafts developed on the old kinetosomes. As a result, the newly developing AZM, TC, FVC, LCC and RCC, emerged gradually from the cytoplasm.Additionally, the influence of temperature to the encystment, and the effect of the con-tractile vacuole on the excystment, were analysed.

包囊游仆虫(Euplotes encysticus)形成包囊时,各类纤毛器中的纤毛杆被部分地或全部地吸收,毛基体被保留下来。休眠包囊中,背纤毛器的定位无明显变化,但原腹面纤毛器中的口围带和波动膜、额腹棘毛和横棘毛,以及左、右尾棘毛都按序陷入在细胞质内深处,并相互汇聚在一起。脱包囊时,纤毛结构在原毛基体上再分化,新纤毛器按口围带、横棘毛、额腹棘毛和左、右尾棘毛的顺序从细胞内显露出来。

By means of optical microscopy, it was observed that during encystment and excystment of Euplotes encysticus the macronucleus (Ma) of a resting cyst was circular in shape and the chromatin granules were few and scatered. Before excystment, there first appeared dense chromatin granules at one or both ends of the Ma and then the whole Ma was filled evenly throughout with dense chromatin granules. Sometimes, some of the chromatin granules were further condensed into chromatin spheres. After excystment, the...

By means of optical microscopy, it was observed that during encystment and excystment of Euplotes encysticus the macronucleus (Ma) of a resting cyst was circular in shape and the chromatin granules were few and scatered. Before excystment, there first appeared dense chromatin granules at one or both ends of the Ma and then the whole Ma was filled evenly throughout with dense chromatin granules. Sometimes, some of the chromatin granules were further condensed into chromatin spheres. After excystment, the Ma and its chromatin granules returned to its normal morphology.From feulgen reaction specimen, the three-dimensional absorbing graph and quantitative data of microphotometry results were obtained. It was clearly shown that the Ma had undergone changes in appearance and size during encystment and excystment. Besides there was a lower DNA content in the Ma of a resting cyst than the Ma of a normal cell. The appearance of dense chromatin granules at one end or at both ends of the Ma was related to the replication of Ma DNA. By the time when the Ma was full of dense chromatin granules the DNA content had reached the level of a normal Ma; and when DNA replication in the Ma was completed, excystment occured.On the basis of the above observations, the author presumes that these changes in DNA content of Ma are obviously related to the encystment and excystment processes. Because no obvious changes were observed in the micronucleus (Mi), it seems that the Mi is not involved in the encystment and excystment process.

包囊游仆虫形成包囊时大核除经历形态大小的变化外,大核DNA含量也低于正常大核水平;细胞脱包囊前,在大核一端或两端发生染色质粗浓集,是大核DNA复制的结果;染色质粒在整个大核内浓集时,大核DNA含量已达到正常大核水平,此时DNA复制结束,细胞脱包囊。小核在游仆虫形成包囊和脱包囊过程中,其形态大小、DNA含量等无明显变化。
