In this study, the effect of glutathione (GSH) on the activity of hydrolytic enzymes of lysosomal, microsomal, and cytosolic fractions was studied in the mouse hepatocytes. The experiments involved 30 Swiss male mice, divided into the experimental and control groups of 15 mice each. The former group received injections of 12 μL/g of GSH solution at a dose of 100 μg/g body weight, whereas the latter received 12 μL/g of physiological saline, all given intraperitoneally daily for 7 days. Then, fragments of liver tissue were collected from the euthanized animals and processed to obtain lysosomal, microsomal, and cytosolic fractions of hepatocytes. The activity of the following enzymes was investigated in vitro: β-glucuronidase, β-galactosidase, β-glucosidase, N-acetyl-hexosaminidase, lysosomal esterase and lipase, acid phosphatase, cathepsin D and L, leucine aminopeptidase, and alanine aminopeptidase. We found that GSH, administered in vivo in the mouse, in the main (73% cases), increased the in vitro activity of the majority enzymes abovementioned, although the effect was somehow variable, depending on the fraction of hepatocytes and the type of enzyme. The findings imply that GSH supplementation may intensify the rate of cellular hydrolytic degradation, i.e., the rate of disposal by the cell of unwanted materials.
