scutum

The efficient embryonic callus system was established by improving culture media and time with callus induced from rice mature embryo scutum.

采用水稻成熟胚的盾片诱导愈伤组织，通过优化培养基组合和调节培养时间，建立了适合水稻遗传转化的胚性愈伤体系，为水稻建立高效的转化体系提供了技术依据。

Results: Scutum erosion were found in 12 of 14 cholesteatoma, 8 of them accompanied with erosion of attic lateral wall.

结果：胆脂瘤中，盾板破坏12例，同时合并上鼓室外侧壁破坏8例；

The results showed that the lipase of rice distribute in the plumule and the scutum, not in the endosperm, It consists of several kinds of isoenzyme.

水稻脂解酶主要位于胚芽及盾片部分，它含有数种性质不同的同功酶；

Conclusion: The destruction of scutum with erosion of attic lateral wall is a feature for cholesteatoma of middle ear.

结论：盾板骨质破坏和上鼓室外侧壁破坏是松弛部胆脂瘤较特征性的CT征象。

Establishment of A Rice Transformation System by Regeneration of Embryonic Callus Induced from Mature Embryo Scutum

水稻成熟胚盾片诱导愈伤组织再生体系的建立

Scutum has a fascinating history.

盾牌座的来历很精彩。

Just like the oxygen isotopic records, the abundance changes of B. scutum indicate the glacial and interglacial cycle and at the same time can be considered as a tool for the stratigraphic classification and correlation.

其丰度变化基本上与氧同位素记录一样，反映了冰期与间冰期旋回，并且可以作为地层划分和对比的工具。

Methods On 60 sides adult temporal bone specimens, the related anatomic structures were well exposed by opening the mastoid cavity and removing the lateral wall of external auditory canal and tympanic scutum.

方法利用成人60侧颞骨标本，用牙科钻磨开乳突腔，打开外耳道外侧壁和鼓室盾板，充分暴露后鼓室入路手术中有关的解剖结构。

Study on callus induction and regeneration from rice mature embryo scutum

水稻成熟胚愈伤组织的诱导和分化因素的研究

RESULTS Cochlea, semicircular canal, scutum, internal auditory canal, vertical segment of facial nerve canal were clearly shown in all cases by different slices of MPR images.

结果MPR影像能在不同切面清楚显示耳蜗、半规管、外耳道骨棘、内听道及面神经管垂直段等结构，显示率为100%。
