Abstract:
BACKGROUND:Proteoglycan, chondroitin sulfate and keratan sulfate, and hyaluronic acid are important substances in the maintenance of intervertebral discs of normal structure. They impact the physiological function of intervertebral disc.
OBJECTIVE:To observe the influence of Liuwei Dihuang Wan on proteoglycan in rabbit models of intervertebral disc degeneration, and to study the efficacy of Liuwei Dihuang Wan on prevention and treatment of intervertebral disc degeneration.
METHODS:80 New Zealand rabbits were randomly divided into Liuwei Dihuang Wan group, model group, sham surgery group and blank control group (n=20 per group). Animal models of intervertebral disc degeneration were established in the model and Liuwei Dihuang Wan groups. In the sham surgery group, surgery via the same approach to expose the lumbar spine was conducted fol owed by layer-by-layer suturing. In the Liuwei Dihuang Wan group, rabbits were given 10 mg/kg Liuwei Dihuang Wan by lavage, once a day. In the model group, sham surgery group and blank control group, rabbits were given an equal volume of physiological saline, once a day, by natural feeding. At 2, 4, 6 and 8 weeks, five rabbits from each group were sacrificed, and intervertebral disc specimens were taken to measure proteoglycan components in the intervertebral disc.
RESULTS AND CONCLUSION:With the extension of feeding time, Liuwei Dihuang Wan could increase sugar amino polysaccharide content, chondroitin sulfate/acid ratio of keratin, and hyaluronic acid content in the intervertebral disc degeneration model, and stabilized the proteoglycan content. Thus, it delayed the degeneration of the intervertebral disc to a certain extent.
