内弹性膜

结论：（1）年老后大脑中动脉基膜增厚，内弹性膜出现脂质，可能是动脉硬化形成的前驱性病变。

CONCLUSSIONS : ( 1 ) The basement membrane thickened and the lipid deposited in the internal elastic lamina of MCA in aged rats , which may be the prelude of atherosclerosis .

结论大鼠大脑中动脉弹性纤维形成完整的内弹性膜，这可能对脑组织具有一定的保护作用。

Conclusion The complete internal elastic lamina of elastic fibers in rat middle cerebral artery may have preventive effect on rat brain tissue .

本研究以兔颈总动脉（RCCA）为材料，采用超低温方法处理RCCA，结果显示此法能够完全去除兔血管内皮细胞层，且血管内弹性膜毫无损伤。

RCCA is treated by super low temperature . The result shows that VEC of RCCA is removed completely , without the damage of the internal elastic membrane of RCCA .

内弹性膜随胎龄增厚、增长、弯曲，有一系列形态变化。

The internal elastic membrane changed progressively with fetal development .

主要观察指标：①主要结局：各年龄大鼠大脑中动脉内弹性膜的变化。

MAIN OUTCOME MEASURES : ① Major outcome : changes of elastic lamella in MCA of different aging rats ;

内弹性膜、中膜、外膜的厚度及管径均随胎龄而增加。

The thickness of the internal elastic membrane , tunica media and tunica adventitia and the diameter of the vessel increased with the increase of fetal age .

观察标本上内皮脱落处的内弹性膜，用立体学方法测量照片上的窗孔数和面积，计算出单位面积上窗孔的平均面积。

By observing the internal elastic membrane on the samples where endothelial cells fell off , measuring the number of fenestrae and relevant area on the pictures with stereological method , and counting fenestra area per unit area .

结果表明：第2个月胚胎内弹性膜已出现很多小孔，第3个月小孔融合成窗孔，随胎龄增长，窗孔数增多，面积增大。

The result is that many small pores appeared on the internal elastic membrane of 2 month old fetus , merged into fenestrae at the 3rd month and the number and area of fenestra increased with the fetus age .

牦牛肺内肺动脉内、外弹性膜清晰可辩，肺内肺动脉管壁内平滑肌、弹性纤维、胶原纤维的含量与管径成正比。

The internal and external elastic laminae were clear in the pulmonary artery . The smooth muscle , elastic fibers and collagen fibers in the pulmonary artery were positively correlated with its outer diameter .
