Hyaluronic acid size variation in angulated and compressed rat discs. Pooled extracts from angulated and compressed discs were analyzed for HA size variation by chromatography through Sephacryl S1000. Panel A compares the convex and concave sides of the instrumented (loaded) angulated disc (Group A). There is a small decrease in HA size in the concave side relative to the convex side. Panel B compares the instrumented (loaded) and distal control discs of the compression group (Group C). There is a major decrease in HA size in the loaded disc. Vo and Vt represent the void and total volumes of the column, respectively.
