The raw data was processed by using axial, coronal and double oblique multi-planar reformation; Images obtained were graded in terms of quality with a 5-point scale(5=excellent, 4=good, 3=fair, 2=poor, and 1=nondiagnostic). In grading image quality at axial MPR, The radiologic specialists focused on the subarcuate fossa, tendon of tensor tympani, facial recess, vestibular aqueduct and pyramidal eminence, In grading image quality at coronal MPR, attention was given to the scute, crista transversa, fenestra cochleae, lateral malleal ligament and snake eyes signature of cranial nerve, In the grading of the image quality at double oblique MPR, the radiologic specialists concentrated on the malleus, incus, stirrup bone, upper bony semicircular and aquaeductus fallopii, and then to implement statistical analysis. In order to choose the minimum tube current values and the maximum pitch that can satisfy the diagnosis request, image quality of axial, coronal and double oblique reformation images was compared with different tube current groups. 15 ears of volunteers were used to test the validity with the scanning parameter. Subsequently noise, MTF and dose length product were measured by phantoms in different tube current and pitch, the parameters obtained were compared and taken into statistics analysis.

播散性浅表性光线性汗孔角化症是一种以多个浅表的角化性皮损，边缘轻微嵴状角化性隆起为特征的少见的慢性角化性皮肤病，呈常染色体显性遗传。

The influences of INA on ovule ultrastructure were also researched. The plasmolysis phenomenon occurred in the nucellar cells, a great deal of bubble structures existed in the cytoplasm, the sterility of plastosome was disarranged or the structure was entirely damaged and turned transparent.

INA细菌对胚珠的超微结构的影响表现为：使珠心细胞发生质壁分离现象，细胞质中存在大量泡状结构，线粒体的嵴紊乱或结构完全被破坏，呈透明状。

The anastomosing occurred between the pleural superficial and the subpleural vascular networks on the capillary level or the precapillary level. The honeycomb vascular networks were also various in size and form at a low magnification. The venule connected with the pulmonary capillary networks directly at a high magnification. The single capillary networks were found in the alveolar septa. The longitudinal crests and dense round imprints of endothelial nuclei and the clear circular constrictions were found on the surface of the larger vessel in the lung parenchyma. The round imprints of endothelial nuclei also occurred on the subpleural venule and capillary.

Results Trunk neural crest stem cells were successfully isolated and cultured. The immuocytochemcal result showed that the cells were nestin-and P75-positive. Trunk neural crest stem cells grew through adhering to chitosan fiber after inoculation. Under an electon microscope, the spindle-shaped trunk neural crest stem cells were proliferated and migrated along the fiber. The cells arranged side by side or linked by heads and tails in processes. The ends of S-100 positive cells were flat and expanded, adhering to the fiber as claw-shaped pseudopodium.

Methods: The distal 1/3 of eighty humeri was scanned by 16 layer spiral CT. The morphologic features of the intramedullary bony prominence above the olecranon fossa were observed and described on coronal, sagittal and transverse section after three-dimensional reconstruction. Then the distal 1/3 of twenty humeri was splitted vertically along the coronal midline for observing the intramedullary bony crista.

The significant differences existed in lower epidermis among materials:in 2 splitting-resistant cultivars,their anticlinal walls had clearly sinuous ridges and the periclinal walls had equal thick ornamentations of cuticles; the defensive cells were rounded cuticles of projected ridges,and epidermal cells were covered with dense powder.

材料间下表皮微形态存在较显著的差别：耐裂材料的垂周壁上有明显的波状嵴，平周壁上有加厚的条纹状角质层纹饰，保卫细胞四周角质层褶皱较多、起伏较大，表皮细胞上覆盖有大量的粉状或颗粒状蜡质。
