Abstract

The effect of vitamin A deficiency on the incorporation of radioactive sulfate (N 37S014,) into the acid mucopolysaccharides of rat skin has been studied. Weanling rats were maintained on a vitamin A deficient diet and Na,37S0,. injected, into groups of rats at various stages of dtficiWncy. The MPS from the skin were isolated and their constituents - uronic acid, Hexosamine and Sulfate, protein and the 535 activity associated with the MPS determined. Similar data was obtained for MPS isolated from skins of vitamin A supplemented controls'. Fractionation of the MPS on DEAE-Sephadex was also carried out The results of these-studies show that vitamin A deficiency resulted in increased incorporation of S35 into rat skin MPS. The proportion of sulfated and non-sulfated MPS was also affected suggesting that vitamin A deficiency affects the turnover rate of sulfated and non-sulfated MPS of rat skin'.
