[Parameters of collagen biosynthesis in cotton pellet granuloma of rats on iron deficiency (author's transl)]. 1978

U Langness, and D Hahn, and T Walther

Rats of Wistar strain, of same age, were kept on iron free diet up to nearly absolute iron deficiency in iron depots. Afterwards granuloma was produced by implantation of cotton pellets subcutaneously. For characterization of the collagen biosynthesis in the granuloma the neutral salt soluble collagen and the activity of the prolyl hydroxylase were measured in the granuloma 4, 8 and 12 days after cotton pellet implantation. At the same time "collagen-like" protein was determined in the serum of the animals. The enzyme activity was statistically significant lower in the granuloma of animals on iron deficiency than in the granuloma of the comparable groups on normal diet. Statistically significant higher concentration of neutral salt soluble collagen was found 8 and 12 days after cotton pellet implantation in the group on iron free diet. There was no significant difference as to the serum levels of "collagen-like" protein in serum.

UI MeSH Term Description Entries
D011393 Procollagen-Proline Dioxygenase A mixed-function oxygenase that catalyzes the hydroxylation of a prolyl-glycyl containing peptide, usually in PROTOCOLLAGEN, to a hydroxyprolylglycyl-containing-peptide. The enzyme utilizes molecular OXYGEN with a concomitant oxidative decarboxylation of 2-oxoglutarate to SUCCINATE. The enzyme occurs as a tetramer of two alpha and two beta subunits. The beta subunit of procollagen-proline dioxygenase is identical to the enzyme PROTEIN DISULFIDE-ISOMERASES.

D006099 Granuloma A relatively small nodular inflammatory lesion containing grouped mononuclear phagocytes, caused by infectious and noninfectious agents. Granulomas
D000747 Anemia, Hypochromic Anemia characterized by a decrease in the ratio of the weight of hemoglobin to the volume of the erythrocyte, i.e., the mean corpuscular hemoglobin concentration is less than normal. The individual cells contain less hemoglobin than they could have under optimal conditions. Hypochromic anemia may be caused by iron deficiency from a low iron intake, diminished iron absorption, or excessive iron loss. It can also be caused by infections or other diseases, therapeutic drugs, lead poisoning, and other conditions.
