[Changes in the serum activity of lysosome enzymes in rats after application of the insecticide propoxur (Baygon)].

The effect of repeated peroral introduction (4 times) of 1/4 and 1/20 LD50 of monomethylcarbamate insecticide Propoxur (Baygon) on the activity of two lysosomal enzymes (beta-N-acetylglucosaminidase and alpha-mannosidase) is studied in the serum of white male rats with starting weight 300 g. Upon using the higher dose, a statistically significant rise (p less than 0.02) of the activity of either of the enzymes is established. The results obtained are interpreted as a sign of impaired permeability of the lysosomal and cell membrane.
