Protective Effect of Ligustrazine on Lumbar Intervertebral Disc Degeneration of Rats Induced by Prolonged Upright Posture

<table>Photomicrographs of IVDs (annulus fibrosus) stained by safranin-O/fast green staining. In the surgery group the laminar structures of the annulus fibrosus were fissures at all time points. Ligustrazine almost completely reversed this disorganization at all time points, which has better effect than meloxicam. The arrow indicates the fissures of annulus fibrosus. Bar equals 100 <i>μ</i>m.</table>
