[Features of potassium metabolism in progressive muscular dystrophy].

The metabolism of potassium was examined by the method of the whole-body radiography with the use of 42K isotope in 50 patients with various forms of progressing myodystrophies, and in 28 healthy subjects who were the patients' relatives. The metabolism of potassium was found to be changed substantially in all the patients and in a part of their relatives. This is important for early diagnosis of the disease, disclosure of carriers of hereditary neuromuscular diseases, and development of treatment methods.
