[Serum enzymatic activity in acute injury to the renal parenchyma]

Studied was the activity of the serum enzymes LAP, CE, APh, SPh, and guanase as well as the isoenzymes of the unspecific esterases and APh in guinea pigs treated with potassium bichromate. Morphologically and histopathologically, an acute injury of the kidney parenchyma was found, being in close correlation with the size of lesions and these enzymes' activity. The activity of APh, SPh, and CE rose, and that of LAP and guanase did not change. These enzymes proved to form an appropriate constallation the changes in which could reflect the functional status of the kidneys and substantiate the differential diagnosis of liver and kidney diseases.
