[Effect of biostator control on levels of contra-insulin hormones].

A 24 hour biostator control was carried out on 30 patients with insulin dependent diabetes, mean age 34 years (16-61 years) and mean duration of the disease 7 years (1-33 years). All patients had normal body mass (+/- 10% according to Broka's formula). The plasma levels of glucagon, growth hormone, cortisol and C-peptide were determined at the beginning and at the end of the biostator control. With the decrease of glycemia (from 12.71 +/- 4.3 to 5.75 +/- 1.5 mmol/l, p less than 0.001) only the cortisol level fell reliably (p less than 0.001), the growth hormone and glucagon levels fell statistically insignificantly. There is no reliable correlation between the contra-insulin hormones studied and the glycemia level.
