不同组分HHK扫描电镜观察

目的：观察Ｆ、Ｂ、Ｚ三种不同的ＨＨＫ表面及断面结构，确立不同降解速度ＨＨＫ的形态学指标，阐明其在自体腱形稆的形态机理，以更好地为临床服务。材料与方法：人发经过不同生化方法处理，制备混合编制快速（Ｆ）、中速（Ｂ）、慢速（Ｚ）三种不同降解速度的ＨＨＫ人工腱在扫描电镜下观察。结果：发现Ｆ组毛小皮大部分脱落，皮质中微丝束融合成消失；Ｚ组毛小波少部分脱落，皮质中微丝不排列略紊乱，而Ｂ组的改变介于前两者之间，

Observation of different HHK groups with SEM

Aim In order to apply the HHK to clinical practice well, we observed the surface and section structures of the HHK and determined the HHK morphological marks of different. dissolution speediness groups and illuminated mechanism of morphological changing during developing of self-tendon. Material and method human hairs were treated with different biochemical reagents and then turn out the HHK man-made tendons which include the HHK of fast (F), mid (B), slow dissolution speediness groups. Three kinds of the HHK were observed with SEM. Result A lot of hair cuticles scale off and microfilament fuse and disappear in F group; some hair cuticles scale off and microfilament lined turbidly; the morphological changing in B group are situated between the F and Z group. Conclusion each of three kinds HHK has its morphological features, so they can apply to clinic successfully. Through clinical experiments it is testify that the HHK are dissoluted finally and the collagen fibers substitute for them and self-tendon are formed.
