[Expression of lysosomal enzymes in pregnancy]

Activities of 6 lysosomal enzymes in leukocytes and 3 enzymes in blood serum were studied in pregnant women. Only activity of beta-D-glucosidase was not altered within all the pregnancy of I-III trimesters, while activity of all the other enzymes studied was distinctly increased to the third trimester. Use of the data obtained in prenatal diagnosis of lysosomal storage diseases is discussed.
