Pancreatic islet-cell antibodies (I.C.Ab) were detected in 31 patients with organ-specific autoimmune disorders, 4 first-degree relatives of I.C.Ab-positive diabetics, and 1 apparently normal subject, none of whom had clinical evidence of diabetes. 10 of these 36 subjects were found to have diabetic glucose-tolerance tests (G.T.T.S), 4 had lag storage, and 22 had normal G.T.T.S.2 had latent diabetes, as evidenced by diabetic G.T.T.S during pregnancy and thyrotoxicosis; another 2 subsequently developed insulin-dependent diabetes (I.D.D.) Serum from 26 subjects had been stored for 1-11 yr before the G.T.T.S were done. The titres in some were shown to rise and fall over the years, while in others they remained remarkably constant. There was no correlation between the titre, change in titre or the duration of I.C.Ab or the presence of HLA-B8, BW15, or CW3 and the result of the G.T.T. In addition to acting as a marker for asymptomatic and latent diabetes and prediabetes, it seems that the presence of I.C.Ab in the serum may define a new group of potential diabetics with normal G.T.T.S. Many such subjects have one or more organ-specific autoimmune disorders (irrespective of diabetic family history), but some are first-degree relatives of I.C.Ab-positive subjects (mainly I.D.D.). About 0-5% of the general population also have I.C.Ab in their serum.

The sympathetic nervous system is of major importance for the regulation of several physiological functions. Drugs which inhibit the actions of catecholamines and adrenergic drugs are used in the treatment of many clinical disorders. The potential role of catecholamines in a number of human diseases has, however, until recent years been studied to a limited extent only due to lack of methods for quantitation of sympathetic nervous activity. After the development of enzymatic isotope-derivative assays, reliable measurements of noradrenaline and adrenaline in plasma became available. Studies in man have shown that plasma noradrenaline is an index of sympathetic nervous activity. The present survey deals with sympathetic nervous activity and plasma adrenaline in a number of clinical disorders viz. arterial hypertension, duodenal ulcer, thyrotoxicosis, diabetes mellitus and ketotic hypoglycemia.

In examination of 123 patients with diabetes mellitus. Itsenko-Cushing disease, Addison's disease, thyrotoxicosis and adiposity there was revealed an increase in the content of the adrenocorticotropic hormone (ACTH) in the blood. Comparison of the ACTH and cortizol concentration in the blood permitted to suppose a different mechanism of the derangements revealed. An increase of the adrenocorticotropic function of the hypophysis in diabetes mellitus, Itsenko-Cushing disease and thyrotoxicosis was accompanied by a rise in the blood cortizol level. A fall of glucocorticoid function of the adrenal glands in Addison's disease and a relative hypocorticism in the patients with adiposity caused a compensatory intensification of the ACTH secretion.

The authors examined 48 patients with different endocrine pathology (relatives of patients with diabetes mellitus with a normal glucose tolerance test, patients with diabetes mellitus, obesity, thyrotoxicosis, and hypothyroidism) and a group of healthy persons. Blood glucagon concentration was determined radioimmunologically on fasting stomach and against the background of insulin hypoglycemia. A marked reduction of glucagon on fasting stomach was noted in patients with diabetes mellitus, and a reduction of the hormone concentration 30 and 60 min after the insulin injection. In obese patients and relatives of diabetic patients the initial blood glucagon level was not different from that in healthy persons. At the same time there was a significant reduction, and in relatives of diabetes patients also a retardation of glucagon secretion against the background of insulin hypoglycemia. The pattern of glucagon secretion in thyrotoxicosis and hypothyroidism proved to be changed.

A study was made of 149 patients with various endocrine diseases, and 30 healthy persons. Despite the sharply increased initial level of growth hormone, somatotropic function of the adenohypophysis was considerably depressed. In patients with hypophysial, cerebral, and somatogenic nanism somatotropic function of the hypophysis proved to be lowered. In diabetes mellitus of moderate severity without any vascular affections with the normal initial blood somatotropin level reaction to insulin hypoglycemia was sharply diminished. Persons suffering from prediabetes displayed a tendency to the change of the somatotropic function of the hypophysis. With increasing adiposity there is a reduction of the initial level of blood growth hormone and of the somatotropic activity of the hypophysis in Itsenko-Cushing's disease and thyrotoxicosis was apparently connected with disturbances of the hypothalamo-hypophysial interrelations.

The content of thyrotropic hormone of the hypophysis (by radioimmunological method) and the level of thyrotropic hormones in the blood plasma were studied in 178 patients with various endocrine pathology (thyrotoxicosis, hypothyroidism, diabetes mellitus, Itsenko-Cushing disease, Addison's disease, adiposity). Healthy persons (33) served as control. Thyrotropic function of the hypophysis proved to be decreased in thyrotoxicosis, diabetes mellitus, adiposity, Itsenko-Cushing disease. Comparison of the plasma level of thyrotropin and thyroid hormones led to a supposition on a different mechanism of the detected changes. A marked intensification on the thyrotropic function of the hypophysis was observed in primary hypothyroidism. A tendency to increase of thyrotropin discharge was noted in the patients suffering from thyrotoxicosis given antithyroid treatment and in Addison's disease.

Hypoglycaemic and growth hormone responses were studied at different steady-state plasma insulin concentrations during a graded infusion of monocomponent human insulin. The control group consisted of ten volunteer subjects. The other groups studied included women taking oral contraceptives and patients with obesity, thyrotoxicosis, myxoedema, acromegaly, diabetes mellitus (moderate and severe) and liver disease. The hypoglycaemic response was measured in two ways: (i) the percentage reduction in plasma glucose below basal, and (ii) the rate of fall of plasma glucose (Kg-%/min). Insulin sensitivity was greatest in the normal subjects and in the other groups decreased in the order thyrotoxicosis greater than oral contraceptive greater than obesity greater than myxoedema greater than acromegaly greater than liver disease. Insulin sensitivity was difficult to assess in the diabetic patients because basal plasma glucose concentrations were elevated. At any given insulin concentration, the diabetics metabolized approximately the same amount of glucose as the normal subjects but the fact that this rate of glucose turnover occurred at higher plasma glucose concentrations probably indicated insulin resistance. Within each group Kg at each dose level of insulin correlated with the steady state plasma insulin concentration during the same infusion period. Diminishing sensitivity to insulin was reflected in an increasing fasting plasma insulin and insulin/glucose ratio except in patients with diabetes. GH responses to insulin infusion in normal subjects reflected the pattern of fall of plasma glucose. In the diabetic patients GH secretion appeared to be related to the infusion of insulin and occurred before plasma glucose had fallen to hypoglycaemic levels. GH secretory patterns were within normal limits in women taking oral contraceptives and in seven of eleven patients with liver disease but were impaired in three of seven patients with thyrotoxicosis and four of five patients with myxoedema. Four obese patients had a markedly delayed but eventually normal GH response.

Two patients with acromegaly have been treated with hypophysectomy. Because the disease was still active, the patients were reoperated. No pituitary tissue could be found at the second operations. Besides the acromegaly, one of the patients had diabetes mellitus (appeared after the first operation), Cushing's syndrome, probably ACTH-dependent, and evidence of thyrotoxicosis. In both patients extopic pituitary tissue was suspected. One of the patients reacted with a normal fall in plasma growth hormone to growth hormone releasing-inhibiting hormone. Ectopic pituitary function should be suspected, if the pituitary function is retained after a hypophysectomy.

In an attemp- to clarify the clinical importance of glucose intolerance associated with acute thyrotoxicosis, 22 patients had evaluations performed for glucose tolerance while thyrotoxic and at mean follow-up times of 8.8 months and 11.6 years after adequate antithyroid treatment. High incidences of glucose intolerance at long-term follow-up (32%) and of histories suggestive of diabetic diathesis (43%) support the hypothesis that there is an inherited relationship between diabetes mellitus and thyrotoxicosis and suggest that initial testing of all thyrotoxic patients for glucose intolerance is advisable. In addition, all thyrotoxic patients displaying diabetic glucose intolerance after a return to the euthyroid state should be considered to have permanent diabetes mellitus until proved otherwise.

The incidence and type of x-ray semeiotics of the skull involvement were studied in 703 patients with endocrine diseases (26 with acromegaly, 36 with hypercorticism, 104 with thyrotoxicosis, 23 with hypothyrosis, 98 with primary hyperparathyrosis, 302 with diabetes mellitus, 114 with hypogonadism). Craniogram analysis involved study of the thickness and structure of the vault bones, shape and size of the skull, status of the sutures, internal plate relief, changes of the base of the skull, of the sella turcica first of all, and facial bones. The characteristic x-ray symptom complexes of the involvement of the skull in some endocrine diseases were distinguished.
