Lysosomal cysteine proteinases (cathepsin H, B + L) and metalloproteinase (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.
在冷冻的、未培养的绒毛膜绒毛中，从妊娠早期（6 - 12周）开始测量溶酶体半胱氨酸蛋白酶（组织蛋白酶H、B + L）和金属蛋白酶（MMP7酶）的活性。组织蛋白酶H的平均活性为50.99 mU/mg蛋白质，组织蛋白酶B + L为71.16 mU/mg蛋白质，MMP7酶为16.16 mU/mg蛋白质。MMP7酶的活性与胎龄相关。组织蛋白酶H和MMP7酶的活性之间存在显著相关性。
