Effects of AET and MEA on the lysosomal hydrolase activities in the mouse organs.
The adult male Swiss mice were injected intraperitoneally with AET (2-aminoethylisothiouronium Br.HBr) or MEA (cysteamine HCl), in a toxic dose of 400 mg/kg body weight. The acid phosphatase (E.C. 3.1.3.2) and arylsulphatase (E. C. 3.1.6.1) activities in crude homogenates of liver and kidneys were assessed every fourth hour throughout a 24-h period. Different patterns of temporal changes in the acid phosphatase and arylsulphatase activities in liver and kidneys expressed in nkat per 1 mg of protein, 1 g of fresh tissue and per the whole organ weight, were found. The extent and timing of the alterations in the activity of each of the lysosomal hydrolases were dependent on the particular organ chosen and aminothiol compound given.
