Lysosomal enzymes in pregnant and steroid treated rats.
The contents of three lysosomal enzymes (beta-hexosaminidase, beta-glucuronidase and alpha-fucosidase) were studied in plasma and different tissues of pregnant and steroid treated rats. All these enzymes were found to be increased in plasma from pregnant rats in analogy with the findings in pregnant women. In liver tissue only beta-hexosaminidase and alpha-fucosidase were significantly increased. In rats with diethylstilbestrol (DES) and a combination of DES and progesterone, there was an increase of alpha-fucosidase in plasma and liver. No significant changes were observed for the other two enzymes. Thus, steroid treatment did not fully reproduce the enzyme changes seen in pregnancy, which may indicate that these are not solely due to a hormone effect.
