since we had previously shown that ascorbate caused a decrease in levels of arylsulfatase a and b activities in normal chondrocyte cultures , the validity of the above relationship was examined by measuring the effect of vitamin c on the biosynthesis and distribution of 35s-labeled proteoglycans and arylsulfatase a and b activities in cell extracts of chondrocytes derived from normal and osteoarthritic tissue .
