The stereocilia of OHCs are extremely short. We can observe thephenomena of rupture and inosculation of stereocilia, which is alike senile deafness ofICR mouse. The OHCs bodies of bats have two leading characteristics. Firstly, theOHCs bodies are obviously short. The Deiters cell phalanges are of exaggerated, andthe cup formation of Deiters cell body enwrap the bottom of the OHCs.

蝙蝠耳蜗外毛细胞体，主要特征有两点：其一是细胞体明显短，三排Deiters细胞的指突明显与顶表面相连，而且毛细胞体基本被Deiters细胞的杯状膜包裹；其二是外毛细胞体在基底部呈烧瓶状，并不是一般哺乳类动物的试管样形态。

Results When RPE cells were cultured with the exotoxin ATCC29213, the LDH level and necrotic RPE cells were positive proportional to the dosage of exotoxin, but only 250μl or 500μl of ATCC29213 had a statistical significant effect.

结果 金黄色葡萄球菌外毒素单独作用RPE细胞时，细胞外LDH水平及RPE细胞的坏死细胞比率随着外毒素剂量增加而升高，但仅250、500μl组差异有统计学意义。

To study the characteristics of the mesenchymal cells of ameloblastic fibrosarcoma, three cases of AFS were studied immunohistochemically and ultrastructurally.

为探讨成釉细胞纤维肉瘤间叶细胞的本质及特征，作者采用免疫组化和电镜技术，对3例AFS间叶细胞进行了研究，并与6例成釉细胞纤维瘤进行比较。

Morphological and flourescent changes were assessed using confocal microscopy in whole-mount organ of Corti preparations. Results (1) After the animals were exposed to broadband noise at 122 dB SPL in 4 h/day for 2 days, both apoptosis and necrosis appeared in OHCs. The single strand DNA in apoptotic OHCs were observed both in guinea pigs and mice.(2) In normal OHCs, EndoG was distributed outside of nuclei. EndoG translocated from outside to inside of the nuclei in both apoptotic and necrotic OHCs following noise exposure.(3) The MNNG cochlear perfusion and noise exposure both caused the transloctation of AIF from the mitochondria to the nuclei. The translocation of AIF took place in both apoptotic and necrotic OHCs.

结果 (1)暴露于120 dB SPL的白噪声环境中每天4小时，连续2天后引起豚鼠和小鼠耳蜗外毛细胞凋亡时，其细胞核内产生ssDNA，而在正常细胞内没有三ssDNA；（2）在正常情况下，EndoG分布于耳蜗毛细胞的细胞核外，在暴露于上述噪声后发生凋亡和坏死的豚鼠耳蜗外毛细胞中，EndoG从细胞核外转移到细胞核内，细胞核中的EndoG显著增加；（3）豚鼠耳蜗外淋巴灌流烷化剂MNNG后发生耳蜗外毛细胞凋亡和坏死，在凋亡和坏死的耳蜗外毛细胞中，AIF自线粒体转移到细胞核，其变化与噪声损伤引起耳蜗外毛细胞凋亡和坏死时一致。

Met hod: Hypertrophy of prostate model rat was established by injecting t estosterone to gelding male rats. After being treated with Qianlie Huichun ig 30 days, the rats were killed and prostate glands were resected for examination. The Fas expressio n was examined by immunobistochemical SABC.

采用大鼠去势后注射丙酸睾酮引起前列腺增生法造模，灌胃给药 30d后，处死大鼠取前列腺组织并称湿重，用免疫组化方法检测前列腺组织中Fas阳性细胞的表达率，用流式细胞术检测细胞凋亡率和观察细胞凋亡峰。

Methods: The effect of MXC on proliferation and apoptosis of granulose cells was assayed by using MTT assay to measure the cell vitality, flow cytometer to detect cell apoptosis, electron microscopy to observe the morphological changes after the action of MXC.

MTT法测定卵巢颗粒细胞在MXC作用后的细胞活力；流式细胞技术检测细胞凋亡变化；电镜观察细胞的形态学改变等；综合评价MXC对卵巢颗粒细胞增殖和凋亡的影响。

DMBQ, ferulic acid and resorcin were effective chemical signal substances in the process of seed germination and haustorium formation of Cistanche deserticola. 4.The embryo is consist of 12 cells, the endosperm cell degraded so as to provide nutrition for the embryo development .As a result, germ tube differentiated from the embryo and came out through micropylar end, the small cell at the tip of the germ tube held the capacity of cleavage and the other cells grew big ,so the germ tube elongated .The anterior extremity of germ tube swelled to form haustorium under chemical substances treatment, the haustorium cell stained ,especially its portrait because of the lignification of the cells.

肉苁蓉种子的胚是由12个细胞紧密排列形成的圆球状胚，球形原胚分裂增殖的同时，胚乳细胞分解，为胚细胞的增殖提供营养，最终胚上分化出的芽管由珠孔端冒出，芽管前端细胞较小，具有旺盛的分裂能力，后部细胞体积增大，芽管逐渐伸长，在化学物质的诱导下，芽管由中部至前端细胞膨大分化出初生吸器，初生吸器呈帽子状，而这些细胞比其周围的细胞着色深，吸器纵向局部区域的番红染色加深，细胞高度木质化。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
