[Connective tissue of rats under prolonged hypokinesia and in the recovery period].

Changes in the content of collagen (with respect to hydroxyproline), total aminopolysaccharides (with respect to hexosamines), and acid glycosaminoglycanes (with respect to hexuronic acids) in the skin and tendons of xuronic acids) in the skin and tendons of 102 white rats (including 46 controls) were determined on the 15, 30 and 90th hypokinetic days and on the 15, 30 and 90th days of posthypokinesia recovery. The hydroxyproline content in the skin and tendons did not change. The content of hexosamines and hexuronic acid decreased in tendons on hypokinetic days 15 and 90 and in the skin on day 15. The content of hexosamines in the skin increased on day 90. The content of hexosamines and hexuronic acids in the skin and tendons increased on recovery day 15 and remained unaltered on day 90.
