In healthy individuals NEZHK content in blood plasma was decreased as 2 hours after injection of 50 g of glucose, and comprised 33% of the original level. With obesity figure was substantially changed.
Curves NEZHK plasma have we observed 157 patients had a number of features typical of the different forms of obesity and allow more or less certain to characterize the functional state of insular systems and initial signs of irregularities. NEZHK curves obtained in these conditions fairly well distributed into 4 groups [Mokina MN, 1972] (Fig. 8).
