Oral vanadyl sulfate improves insulin sensitivity in NIDDM but not in obese nondiabetic subjects.

We compared the effects of oral vanadyl sulfate (100 mg/day) in moderately obese NIDDM and nondiabetic subjects. Three-hour euglycemic-hyperinsulinemic (insulin infusion 30 mU / m / min) clamps were performed after 2 weeks of placebo and 3 weeks of vanadyl sulfate treatment in six nondiabetic control subjects (age 37 +/- 3 years; BMI 29.5 +/- 2.

Oral vanadyl sulfate improves hepatic and peripheral insulin sensitivity in patients with non-insulin-dependent diabetes mellitus.

We examined the in vivo metabolic effects of vanadyl sulfate (VS) in non-insulin-dependent diabetes mellitus (NIDDM). Six NIDDM subjects treated with diet and/or sulfonylureas were examined at the end of three consecutive periods: placebo for 2 wk, VS (100 mg/d) for 3 wk, and placebo for 2 wk. Euglycemic hyperinsulinemic (30 mU/m2.

Counterregulation of hypoglycemia. Skeletal muscle glycogen metabolism during three hours of physiological hyperinsulinemia in humans.

We examined the role of skeletal muscle in counterregulation of hypoglycemia (3.4 +/- 0.1 mmol/l) in 12 nondiabetic individuals (age 26 +/- 1 years, body mass index 24.

[Sensitivity of isolated adipose tissue to insulin and questions concerning the pathogenesis of diabetes mellitus in patients with chronic liver diseases].

Immunoreactive insulin level proved to be elevated in the blood serum on fasting stomach and at various periods after glucose administration in patients with cirrhosis of the liver with normal glucose tolerance. Reduced insulin sensitivity of the isolated adipose tissue was observed in patients with cirrhosis of the liver. The blood serum cortisol level in these patients failed to differ from such in healthy persons; that calls in doubt participation of this contrinsular hormone in the genesis of reduced insulin sensitivity in chronic diseases of the liver.

[Clinical picture and pathogenesis of diabetes mellitus in chronic hepatitis and cirrhosis of the liver].

Peculiarities of clinical picture of diabetes mellitus in its combination with chronic hepatitis and cirrhosis of the liver were studied in 60 patients. Diabetes mellitus developed mostly against the background of chronic affection of the liver, preceding it. Glucose tolerance disturbances according to the type of latent and manifest diabetes were revealed in 28% of 132 patients with chronic hepatitis and cirrhosis of the liver.

[Functional and morphological state of the liver in secondary cholangitis].

Studies on the liver state from the functional-morphological point of view in patients with acute and chronic secondary cholangitis have revealed in all cases the involvement of hepatic parenchyma with the development of cholangiohepatitis. In its acute course and timely performed operative interventions the process in the liver tends to subside. The authors consider that due to the absence of pure forms of cholangitis this term seems to be questionable, and they recommend to substitute it in all cases by the term cholangiohepatitis.

[Triiodothyronine thyrotoxicosis in nodular toxic goiter].

Serum protein-bound iodine (PBI), total blood thyrotoxin (T4), triiodthyronine (T3), coefficient of thyrotoxin efficacy (CTE), serum thyrotoxin-binding capacity (TBC) or some of these indices were determined in 44 patients with nodular toxic goiter with thyrotoxemia. An increase in T3 level was revealed in 27 of 35 of the patients; T3-thyrotoxicosis was diagnosed in 18 of these in whom an increase of the T3 level was combined with normal T4 or normal CTE content and an unchanged TBC. The symptoms of T3-thyrotoxicosis displayed no significant differences from the symptoms of thyrotoxicosis caused by the excess of thyroxin.

[Relationship between lipid and carbohydrate metabolism and hyperinsulinemia in coronary arteriosclerosis].

The disorders in the carbohydrates metabolism were studied along with the level of insulinemia in patients with coronary atherosclerosis, and the interrelationship between the pathological shifts in the lipid and carbohydrates metabolism were clarified. The study was conducted in 45 persons: 31 patients with coronary atherosclerosis and 14 normals. The indices of the lipid (cholestrol, triglycerides, NEFA, lipoproteids) and carbohydrates metabolism (blood sugar immunoreactive insulin) were analysed on an empty stomach and after glucose provocation.
