We studied 56 biopsy samples of conjunctiva and 50 corneal discs excised from 28 patients with acquired keratoconus cornea.
      
Necrobiotic changes have been revealed in epithelium of the corneal discs going by the pathways of apoptosis-programmed cell death-and oncosis-initial edematic stage of necrobiosis.

Previous studies had shown thatwhen the paranecrotic skin of thetadpole was transplanted to the positionof the excised cornea of a tadpole atthe same stage,this piece of skin wastransformed into a new cornea muchmore rapidly than the intact one. In this paper the authors made anattempt to compare the ultrastructuresof normal tadpole skin with that ofparanecrotic skin caused by low con-centration of acetic acid(0.01N)andof ammonia water(0.001N).Certainultrastructural changes in the skin underthe conditions of...

Previous studies had shown thatwhen the paranecrotic skin of thetadpole was transplanted to the positionof the excised cornea of a tadpole atthe same stage,this piece of skin wastransformed into a new cornea muchmore rapidly than the intact one. In this paper the authors made anattempt to compare the ultrastructuresof normal tadpole skin with that ofparanecrotic skin caused by low con-centration of acetic acid(0.01N)andof ammonia water(0.001N).Certainultrastructural changes in the skin underthe conditions of paranecrosis are foundas follows: (1)The tonofilaments in the ehider-mal cells become more or less aggre-gated and appeared loosened.Thesechanges are more obvious in the skin ofweak acid treatment. (2) The organelles in epidermal cellsare decreased in quantity,numerousvacuoles are observed in the cytoplasm;the intercellular spaces between adja-cent cells have become narrowed thanthe normal. (3)The chromatin granules arefound in condensed clumps scatteredunevenly throughout the nucleus,lea-ving irregular spaces in the nucleus. (4)The dark and light periodicbands of the collagenous fibres in thebasement membrane are obscure incontours. The changes mentioned above arediscussed in relation to the possiblemechanisms of quickening the processof corneal induction under the conditions of skin paranecrosis.

已知发生类坏死的无尾两栖类蝌蚪皮肤,可加速被眼诱导为角膜的进程。采用弱酸(0.01N醋酸)和弱碱(0.001N氨水)处理花背蟾蜍蝌蚪皮肤使之发生类坏死,对比观察了正常和发生类坏死皮肤的超微结构,结果发现皮肤在类坏死条件下发生下列变化:(1)表皮细胞内的张力原纤维显得疏松,有变粗及聚集的现象,弱酸处理者更明显;(2)表皮细胞中细胞器减少,细胞质内出现大量液泡;相邻细胞的细胞间隙变狭窄;(3)表皮细胞核内的染色质分布不均匀,浓缩为较大的团块,使核内出现不规则的空隙;(4)基膜中胶原纤维明暗相间的条纹结构较模糊。文中对类坏死条件下皮肤超微结构的变化和加速角膜诱导进程间的可能关系进行了讨论。

It shows that the insertion lines are various in forms, straight, curved, waved, spiral or serrated.

The changes of the morphologicalarchitecture of the cell surface of thecorneal epithelium during the morpho-genesis of the eye in Bufo raddei Strauchwere observed with scanning electronmicroscopy.They may be dividedinto three periods:1.From neuraltube stage (stage 16) to muscularresponse stage (stage 18) there are noevident differences between the pre-sumptive corneal epithelium and theepidermal ectoderm in the region of ??head (fig 1).They all include bothciliated cells and non-ciliated cells(fig 2).2.In...

The changes of the morphologicalarchitecture of the cell surface of thecorneal epithelium during the morpho-genesis of the eye in Bufo raddei Strauchwere observed with scanning electronmicroscopy.They may be dividedinto three periods:1.From neuraltube stage (stage 16) to muscularresponse stage (stage 18) there are noevident differences between the pre-sumptive corneal epithelium and theepidermal ectoderm in the region of ??head (fig 1).They all include bothciliated cells and non-ciliated cells(fig 2).2.In heart beat (stage 19)and gill circulation (stage 20) stageson the surface of the presumptivecorneal epithelium appear many cel-lular constrictions and sinkings of thecell surface under the constrictions(fig 3).In gill circulation stage the ciliaof a few ciliated cells (arrow) beginto regress (fig 4).3.In latter stagesthe cilia of ciliated cells in the cornealepithelium all gradually regress anddisappear (fig5).Most of the ciliahave rapidly disappeared in tail fincirculation stage (stage 22,fig 6).The cilia on the ciliated cells completelyregressed in opercular fold stage (stage23,fig 7).The ciliated cells in cornealepithelium have completely disappe-ared when the operculum closed onright stage (stage 24.fig 8).Theciliary length of ciliated cells in cor-neal epithelium and in epidermal ecto-derm show different changes duringlatter stages (from stage 20 to stage25.Table 1). These changes of the morphologicalarchitecture of the cell surface ofcorneal epithelium during morpho-genesis of the eye are presumablycorrelated with the development ofthe retina and of the photoreceptorsin it.The regression and the disappea-rance of the cilia of ciliated cells incorneal epithelium more exactlyreflect this dependent relationship thanthe disappearance of the pigment inthe cornea.It may be served as amorphological index of differentiationof the cornea.

扫描电镜观察表明,花背蟾蜍眼形态发生过程中角膜上皮细胞表面形态结构的变化,大致可分三个阶段。1.从神经管期至肌肉感应期预定角膜上皮表面无明显变化;2.在心跳期和鳃血循环期预定角膜上皮表面出现较多的细胞缢束和其下细胞表面的下陷;3.在以后各期,角膜上皮中纤毛细胞的纤毛逐渐退化消失,在右鳃盖封闭期纤毛细胞全部消失。上述变化与视网膜及其中光感受器的发育分化密切相关,纤毛的退化和消失更精确地反映了这种依赖关系,似可作为角??膜上皮分化的一个形态指标。
