Plasmatic arginine vasopressin levels in total and partial diabetes insipidus.

Plasma arginine vasopressin (AVP) was measured in 24 patients with polyuria exceeding 3.5 l/day diagnosed as severe or partial diabetes insipidus according to the dehydration test. All patients with severe diabetes insipidus diagnosed by the dehydration test had very low or undetectable basal AVP values and always subnormal plasma osmolality. Patients with partial diabetes insipidus diagnosed by the dehydration test had a wide range of AVP and osmolality values. The stimulation test performed on these patients was able to differentiate patients with primary polydipsia from patients with partial diabetes insipidus. The measurement of basal plasma AVP is capable of diagnosing all patients with severe diabetes insipidus; when we combine the stimulation test with the measurement of AVP, we can differentiate partial diabetes insipidus from other forms of polyuria.

Influence of exercise on serum levels of myoglobin measured by radioimmunoassay.

To determine the influence of exercise on serum levels of myoglobin, serum levels of this protein were determined by RIA in 90 healthy men, divided as follows: (1) Basal control (no exercise) 25 cases; (2) Moderate exercise (after subject had been working for 12 h in Medicine Emergency Service) 19 cases, and (3) Intensive exercise: (a) football professional (45-min match) 10 cases; (b) football amateur (45-min match) 10 cases; (c) basketball professional (45-min match) 10 cases, and (d) basketball professional (90-min training) 16 cases. Our results led us to the following conclusions. (1) Moderate exercise, such as the usual daily work, does not modify myoglobin levels; (2) Myoglobin serum levels after exercise increase in nearly all individuals. They are higher in untrained people; (3) There seems to be a correlation between exercise intensity and increase of myoglobin serum levels, and (4) The detection of serum myoglobin by RIA may have a wide field of application for sport medicine.
