Lysosomal cysteine proteinases (cathepsin H, B + L) and metallopro‐teinase (MMP7‐ase) activities were measured from early gestational period (6‐12 weeks) in frozen, non‐cultivated chorionic villi. The mean activity of cathepsin H was 50.99 mU/mg protein, of cathepsin B + L, 71.16 mU/mg protein, and of MMP7‐ase, 16.16 mU/mg protein. The MMP7‐ase enzyme activities showed a correlation with gestational age. There was a significant correlation between the activities of cathepsin H and MMP7‐ase. 1990 Acta Obstet Gynecol Scand
