观察孔

Methods Twenty guinea pigs with gentamicin-induced hearing loss were randomized equally into IGF-1 group and control group. In both groups, scala tympani fenestration was performed for injection of IGF-l (10μ1) or artificial perilymphatic fluid (10μl). Auditory brainstem responses test was performed before and 7 and 14 days after surgery, respectively, and the cochlea was removed by decollation of 3 guinea pigs from each group after ABR test for observing the changes in the hair cells using scanning electron microscope.

豚鼠20只，施用庆大霉素致耳聋后均分为IGF-1组和对照组，行鼓阶开窗术，微孔技术注入试剂（IGF-1组注入鼠重组IGF-1，对照组注入人工生理外淋巴液）10μ1，分别在术前和术后7、14d行ABR测试；测试完后每组3只断头取听泡，在扫描电镜下观察耳蜗毛细胞改变。

Purpose: The purpose of this study was to use non-invasive cephalometric radiography to study the location and the changes in location of the mandibular foramen in Taiwanese adults and children.

研究目的：本研究的目的是要利用非侵入性的侧颅放射线摄影的方式，来观察人类下颚孔的位置及其随年龄的变化。

Methods: Among these 32 patients with narrow nasal valve,10 were operated with anterior inferior turbinectomy,4 with deviation orthopedic of protruding trian gular outer cartilage (2 on the left,2 on both sides),6 with bone-widen operation of osseous pyriform aperture(2 on the left,4 on both sides).The nasal ventilation before and after operation was observed.

32例鼻瓣膜区狭窄患者，行下鼻甲前端切除术10例，鼻外侧软骨凸出矫正术4例(左侧2例、双侧2例)，骨性梨状孔狭窄扩大术6例(左侧2例、双侧4例)，观察手术前后鼻通气改善情况以判定疗效。

The lenticel rooting was studied with scanning electron micro...

对皮孔出根作了扫描电子显微镜观察。

The cold-shock treatment with ozonated water (ozone concentration 2 mg/L, dipping 5 min in the 1 ± 1 ℃cold water) reduced quantities of bacteria and funguses of winter-jujube, and decreased the rate of loss weight, and extended shelf-life of the fruit. By the ultrastructures of winter-jujube pericarp, cold-shock treatment with ozonated water could clean out the waxiness of crackle and lenticel, which is helpful for exchange of fruit internal CO2 and air, and inhibit accumulating of ethanol concentration.

臭氧水冷激处理(臭氧浓度为2mg/L，浸泡时间5min，水温1±1℃)可以明显降低冬枣表面细菌和真菌的数量，减少失重率，延缓冬枣硬度的下降，提高冬枣的货架期；从微观结构观察发现，臭氧水冷激处理可以清洗冬枣表皮裂缝和皮孔的蜡质，有助于枣果内部CO_2气体的排逸，从而延缓了冬枣的酒化；此外，冷激处理可以明显降低冬枣表面残留的农药：如马拉硫磷、氯氰菊酯和溴氰菊酯农药的含量，提高枣果的食用安全性。

Methods Star anise were extracted from Illicium verum Hook.f. using ethanol and ethyl acetate as solvents. After macron absorption resin layer separation, a kind of white fine powder shikimic acid were obtained. The extracted shikimic acid were determined for chemical qualitative analysis.

These experimental observations indicated that adsorption of phenol on the polymeric resins depended greatly ontheir microporosity and surface chemistry.

这些实验性观察表明酚的吸附在聚合物树脂很大地依靠了得ontheir微孔性和表面化学。

In the functional cell such as archesporial cell,megasporocyte,dyad,tetrad and youngmegaspore,among which the three cells close to micropyle end do not degeneratewholly,no clear starch grains were observed as well as in the embryo sacs from singlenucleate embryo sac to 8-nucleate one just forming.

淀粉粒变化有规律性，在孢原细胞、大孢子母细胞、二分体、四分体和早期的大孢子（即四分体中近珠孔端的3个细胞未完全退化）等功能性细胞中未观察到明显的淀粉粒。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.
