Effect of levamisole on malignant experimental neurinoma grown subcutaneously in a young rat: brief communication.

Levamisole, a drug that stimulates the immunologic defenses of the host, was tested on the experimental malignant neurinoma grown subcutaneously in young female inbred CDF rats in 3-month trial. The drug resulted in prevention of tumor growth in 80% of the treated animals, whereas tumors grew in 100% of the controls. After discontinuation of the drug, none of the animals in the treated group showed evidence of tumor growth upon clinical and pathologic examination 1 month after drug treatment was terminated. Treated animals failed to show any side effects related to levamisole upon clinical and pathologic examination.

Islet-cell antibodies in diabetes mellitus.

Islet-cell antibodies (I.C.A.) were found in 38% (319/829) of insulin-dependent diabetic patients, in 5% (6/112) of insulin-independent diabetics, and in 1.7% (3/177) of non-diabetic subjects. In the insulin-dependent group I.C.A. were found in 85% of patients immediately after the onset of symptoms and they became less common as the duration of disease increased I.C.A. were equally common in both sexes and the decline in their prevalence was independent of age. The antibodies were directed against cytoplasmic components of islet cells but not against insulin itself. The appearance of I.C.A. probably follows cell damage occurring before the onset of symptoms. By contrast, thyroid and gastric autoantibodies were more common in older patients and females. There was no correlation between the presence of these antibodies and I.C.A. in patients with either diabetes of recent onset or longstanding disease.

Is glucagon important in stable insulin-dependent diabetics?

The role of glucagon has been evaluated in the everyday regulation of carbohydrate and lipid metabolism in insulin-dependent diabetic patients. Plasma concentrations of glucagon, growth hormone, cortisol, glucose, and free fatty acids and blood concentrations of glycerol, 3-hydroxybutyrate, acetoacetate, alanine, pyruvate, and lactate were measured in 38 fasting diabetic subjects deprived of their usual morning dose of insulin. The measurements were repeated in 25 of these patients after a further 3 hours of insulin deprivation and in 6 patients again at 6 hours. There was no correlation between the initial fasting levels of plasma-glucagon and those of the other biochemical measurements including glucose and ketone bodies. Furthermore, no correlation was found between changes in these measurements and in plasma-glucagon over a period of 3 or 6 hours. These findings suggest that glucagon is unlikely to play a role of primary importance in blood-glucose homoeostasis or ketone-body metabolism in ambulant insulin-dependent diabetic patients.

Register of newly diagnosed diabetic children.

In November 1972 the British Diabetic Association sponsored a register to which notification was invited of all new cases of diabetes occurring in children aged 0-15 years in Great Britain and Ireland. More than 2000 cases were notified in the first two years. Notification suggested that there was a minimum yearly incidence of 7-67 cases per 100 000, though incidences varied from year to year and by geographical area. Several reports of simultaneous onset of diabetes in sibs of different ages provided evidence of clustering. A seasonal variation in incidence was found in children aged 5-15 years with peaks in the autumn and winter. The age distribution was bimodal with a main peak at about 11 years and a secondary peak at about 5 years. The sex ratio showed a male excess from 0-4 years and from 11-15 years and a female excess from 5-10 years. Overall there were slightly more male cases. Altogether 11% of patients had a first-degree relative with diabetes. The register and several investigations based on it will continue.

Assessment of the need for continued oral therapy in diabetics.

Hypoglycaemic agents were replaced by placebos in diabetic patients attending a hospital clinic. Of 62 patients observed, 43 (69%) relapsed within six months but blood sugar control remained unchanged in 19 (31%) during the period of observation.
