滋养核

On the morphological differentiation,by inducing of fetal calf serum,it wasshown that the cytotrophoblast cells underwent aggregation first,and the adjacentcytoplasm membranes became tightly contacted through desomosomes andcytoskeleton.Then the adjacent cytoplasm membranes disintegrated fragmentallyto form fusion pore-like structure.Finally the multinuclear cells formed and inwhich the intercellular desmosomes disappeared.Immunocytochemical stainingfurther demonstrated that the formation of syncytium was through cell membranefusion rather than the amitosis process.

细胞形态分化的研究结果表明：早孕胎盘来源的细胞滋养层细胞在血清诱导下，首先发生聚集，并通过桥粒和细胞骨架使相邻的细胞膜紧密接触；之后细胞膜发生片段断裂，形成融合孔样结构；细胞间桥粒消失，最终形成多核的合体细胞；免疫细胞化学分析进一步证实合体化是通过细胞膜融合而非无丝分裂（amitosis即细胞核分裂而细胞质不分裂）实现的。

The antiparasitic effect of caprylic acid against several fish parasites, i.e., the ciliate Cryptocaryon irritans, monogenean Benedenia seriolae, copepod Pseudocaligus fugu and myxosporean Kudoa shiomitsui, was examined by in vitro trials.Caprylic acid at a concentration of 1 mM had a parasiticidal effect against C. irritans theronts, B. seriolae oncomiracidia and K. shiomitsui spores and a contractile effect against B. seriolae adults, but had no clear effect against P. fugu copepodids and adults.

在体外实验中研究了辛酸对多种鱼类寄生虫的抗虫效果，如纤毛虫刺激隐核虫、单殖吸虫鰤贝尼登虫、桡足类Pseudocaligus fugu和微孢子虫库道虫。1mM的辛酸对刺激隐核虫滋养体、鰤贝尼登虫纤毛幼虫和库道虫孢子具有杀虫效果，对鰤贝尼登虫成虫有收缩效果，但对Pseudocaligus fugu的桡足幼体和成虫无明显效果。

Objective: To investigate the relationship of PPARγ, MMP-2 and MMP-9 with trophoblast invasion.

目的：探讨Ⅱ型核受体的过氧化物酶体增殖物激活型受体γ、金属蛋白酶-2和MMP-9与细胞滋养细胞浸润的关系。

No significant correlation between nucleus roundness and trophozoite roundness.

滋养体圆度和核圆度之间无相关性。

An analysis revealed very significant positive correlation between trophozoite area and nucleus area (r=0.54, P .01), trophozoite volume and nucleus volume(r=0.47, P .01), and negative correlation between trophozoite area and trophozoite roundness (r=-0.29, P .01), no significant correlation between nucleus roundness and trophozoite roundness.

相关分析显示滋养体与核的面积(r=0 。5 4 ，P 。0 1)、滋养体与核体积(r=0 。4 7，P 。0 1)相关性有显著性意义，滋养体面积和核圆度呈负相关(r=- 0 。2 9，P 。0 1)，滋养体圆度和核圆度之间无相关性。

The samples were smeared on slides and stained with Giemsas stain. The stained smears were observed microscopically and photographed. It showed that except typical trophozoites in binary fission. the following trophozoites of abnormal morphs were also observed. for instance abnormal trophozoites with binary fission; enlarged trophozoites with round and irregular shaped eosinophilic bodies in the cell plasma; enlarged cells containing round and irregular shaped eosinophilic bodies and flagella; enlarged cells which contain 6 or 8 nuclear-like bodies and flagella, 3 or 4 embryonic forms of daughter trophozoite in one mother trophozoite; 4 trophozoite embryonic forms with fused plasma 3 trophozoites with fused plasma;4 trophozoites with fused plasma; a pair of trophozoite with binary fission fused with another trophozoite;2 pairs of trophozoite with binary fission fused each other; a trophozoite with 1 nuclear only.
