摘要

p1. Granulation tissue from healing tendonectomy wounds in guinea pigs was analysed and the effects of inanition and ascorbic acid deficiency on this tissue were investigated. 2. Inanition produced no significant effect on either the glucosamine or the galactosamine content of the tissue. Ascorbic acid deficiency decreased the galactosamine content without affecting the glucosamine content. 3. Fractionation of papain-digested granulation tissue gave three major fractions, which behaved respectively as glycopeptide, hyaluronic acid and a sulphated glycosaminoglycan mixture. At least half of the sulphated glycosaminoglycan mixture behaved as dermatan sulphate. 4. Inanition produced no consistent effect on the fractions examined. In ascorbic acid deficiency, a decrease in the sulphated glycosaminoglycan fraction was observed, which accounted for the decreased galactosamine content of the tissue. This was accompanied by a decrease in hyaluronic acid and a slight increase in the glycopeptide fraction./p
