In vitro study on osteogenic potential of annulus fibrosus in the cervical intervertebral disc of cervical spondylosis myelopathy patients;

Objective To explore the relationship between pathomorphologic variation in lumbar intervertebral disc posterior annulus fibrosus and low back pain of lumbar disc degeneration diseases.

Methods Proteins in both annular fibrosus and nucleus pulposus was extracted from normal subjects,the aggrecan was removed by cesium chloride gradient centrifugation,proteins was separated by two dimensional electrophoreses and identified by matrix .

Intervertebral disc is one kind of cartilaginous tissue which is composed of tremellose nucleus pulposus in the center and annular fibrosus arranging in concentric circle one the periphery, endure the loading of the body.

Methods: We incised the anulus fibrosus of intervertebral disc of rabbit to make the nucleus pulposus contact with the nerve root.

In the paper, the present situation and products regulating countermeasure of our textile industry are analysed according to the fierce rivalry after acceding WTO, and in future the exploiting orientations of knitgoods are proposed on the basis that the characteristics of environment protective fiber, differential fiber and functional fiber are explored.
