Original abstract
The activities of the aminotransferases, GOT and GPT, were determined in the serum and cerebrospinal fluid of patients with Parkinson's disease, Huntington's chorea, Wilson's disease, amyotrophic lateral sclerosis (ALS), Friedreich's ataxia, phenylketonuria, and head injuries. 1. In patients with Huntington's chorea the activity of SGOT was lower than in controls (P = 0.02); in Friedreich's ataxia LGPT activity was decreased (P less than 0.001); in patients suffering from ALS SGOT (P = 0.005), SGPT (P less than 0.001) and LGOT (P less than 0.001) activities were increased. 2. Long-term treatment of Parkinson's disease and Wilson's disease with L-dopa resulted in an increase in SGOT, LGOT, and SGPT activity over approximately 2 months, with subsequent normalization of these enzyme activities in spite of continued therapy. Guanidine treatment led to an increase in aminotransferase activities in patients with ALS. Penicillamine caused a decrease in SGOT and SGPT activities in Wilson's disease. These results illustrate the necessity of taking therapeutic measures into account in the interpretation of data on aminotransferase activities.
