Objective: on the guidance of the vitodynamics theories ,we set up the rabbit model of lumbar vertebrae vitodynamic imbalance , and use the histomorphology and immunology theory to detect and analyze the intervertebral disc tissue after the model has been built, and investigate the connection of lumbar vertebrae vitodynamic disbalance and lumbar intervertebral disc tissue cataplasis. Otherwise, through the analysis of experimental data, pathomechanism was explained that lumbar vertebrae vitodynamic disbalance lead to lumbar intervertebral disc tissue cataplasis,protrusion and lumbar spine degenerative disease process, to guide the prevention and cure of lumbar degenerative disease process and lumbar intervertebral disc tissue cataplasis, lumbar disc herniation ,at the same time to provide functional exercise the theory basis.Method: 32 rabbits, half female and half male,10~12 months old, were randomly divided into 4 groups : dynamia disbalance model group,static force unbalance model group,dynamia and static force disbalance model group ,control group. Each group has 8 rabbits. Cutting transversally erector spinae and musculus latissimus dorsi to set up the dynamia disbalance model. Cutting ligament supraspinale,interspinal ligaments and ligamentum transversum to set up the static force unbalance model. The dynamia and static force disbalance model was set up by cutting all the musles and ligaments mentinged previously. Control group had the other 8 rabbits that were only cut skin . Penicillin was used through intramuscular injection in erery rabbit for one week after the model had been set up. Meanwhile raising the rabbits 3 monthes , then killing the animals and dislodging the intervertebral disc tissues of lumbar 3 and lumbar 4 and lumbar 5. At last making pathologic observation and biochemical detection.Results:1.Through the rabbit anatomical observation, dentifying the local anatomic structure of lumbar spine.2.Through tectological observation we found: annular fibrosus was rimous of discus intervertebralis in model groups, array was gently irregular, even the normal structure of annular fibrosus was disappear, being fibrotic; and nucleus pulposus was...
