The present study was undertaken to investigate the biochemical changes of collagen in animal joint capsules and muscles on traumatic dislocation and sciatic nerve cutting.
1. Collagen was extracted from a dog M. gluteus medius and M. biceps femoralis on traumatic dislocation.
2. The amounts of soluble collagen in the dislocated joint capsules and M. gluteus medius were richer than those in a normal joint, but there were no changes in the amounts of reducible cross-links in any tissues.
3. These data suggest that traumatic dislocations have no effect on the stability of collagen in the joint capsules and muscles.
4. Collagen was ext r acted from a rabbit M. gluteus medius, M. biceps femoralis and M. gastrocnemius by sciatic nerve cutting.
5. The amounts of total and soluble collagen and reducible cross-links were richer than those of normal muscles put under the sciatic nerve.
6. These data suggest that the collagen of the M. biceps femoralis and M. gastrocnemius produce relatively immature fibers compared with a normal joint.
7. All these data may suggest that the results of collagen in the L-S are inherent.
