The intranasal application of an insulin solution in dogs resulted in the rise of plasma immunoreactive insulin and in dose-dependent hypoglycemia. The absorption of insulin from this site was found to be enhanced when insulin was dissolved in an acid medium. In addition, when an insulin preparation with some surfactant was used, the effectiveness of nasally administered insulin was 25 to 30 per cent of that achieved with intravenously administered insulin.

The hypothalamic regulatory hormones used for clinical studies are TRH, Gn-RH and somatostatin. In addition, as dopamine appears to be a physiological PIF, the dopamine agonists such as bromocriptine, could be considered as functional analogues of PIF. Gn-RH can be used to study the hypothalamic-pituitary gonadal relationship and to test the secretory reserve capacity of the gonadotrophs in disease states. Unfortunately Gn-RH testing discrimulates between pituitary and hypothalamic diseases only poorly. However gonadotrophin deficient men or women may be successfully treated with long-term Gn-RH with induction of puberty, potency, spermatogenesis and ovulation. Somatostatin has multiple actions in inhibiting endocrine and exocrine secretion but its actions are still being explored in diabetes. Bromocriptine, a long acting dopamine agonist (a functional analogue of PIF), suppresses prolactin and is highly effective in treating many hypogonadal states since hyperprolactinaemia is common. It also lowers growth hormone in acromegaly. TRH has provided a major, accurate, sensitive and safe test of thyroid function.

Oxyhemoglobin dissociation curves (ODC) were performed on blood from newly diagnosed, nonketotic diabetics prior to and following initial insulin treatment and from ambulatory juvenile diabetics before and after their usual morning insulin. In 10 newly discovered diabetics the average P50 at in vivo pH was normal prior to insulin (26.2 mm Hg), decreased to 24.5 mm Hg (p less than 0.005) on the day following the initial insulin administration, and was within normal limits (26.9 mm Hg) when the diabetes was finally well controlled and red cell 2,3-diphosphoglycerate (2,3-DPG) had risen to elevated levels. Oxygen affinity of hemoglobin was closely correlated with the content of red cell 2,3-DPG (r = 0.61, p less than 0.001) but was unrelated to the level of hemoglobin Alc. In 40 juvenile patients the average P50 was also normal prior to insulin administration but was significantly lower 3-4 hr after they had received their usual insulin dose (p less than 0.001). The study indicates that insulin administration to diabetics with high blood glucose levels may lead to transient decreases in red cell 2,3-DPG and in oxygen-releasing capacity of the red blood cells.

The lipoprotein-lipase activity (LPLA) in the abdominal, subcutaneous, adipose tissue was studied in a random sample (n = 69) of 60-year-old men. A new method for the quantification of LPLA was applied. The mean value was 67 mU/g when expressed per gram (wet weight) of adipose tissue. Several subjects within the lower part of the range of adipose-tissue LPLA values had low concentrations of serum-triglycerides (S-TG). There was no correlation between the LPLA and S-TG concentrations in the fasting state. Among the 69 subjects, four had newly detected diabetes mellitus and had significantly lower LPLA in the adipose tissue than the control group. The fat-cell size and the LPLA per gram of adipose tissue were not correlated. Thus, obesity without diabetes mellitus does not imply a low LPLA concentration in adipose tissue. The variation of the concentration of adipose-tissue LPLA in the fasting state in this population was explained only to a minor extent by the variation of S-insulin and blood-glucose parameters, when analysed statistically by a stepwise multiple-regression technique.

208 hospitalized patients, nearly 80 years old, were investigated because of risk factors and complicating diseases. Hypertension (58.2%), typical myocardial infarctions (37.2%) and diabetes (45.2%) were twice often as in our comparable cases without stroke. Corresponding we found signs of left ventricular hypertrophy in more than 50% post mortem. The dimensions of heart failure by hypertension are visible in ECG indicating LVH with many dysrhythmias. Early mortality (40%) as survival time are dependent on the size of the stroke. Cardiovascular causes of death were found mainly. The differences to younger patients with brain infarction seem to be only of gradually nature and especially to refer to the more intensive damaged heart.

A new method of eliminating the exocrine function of the pancreas by obstruction of pancreatic duct with neoprene was investigated in dogs and applied to three cases of human segmental pancreatic transplantation. Neoprene is a liquid synthetic rubber which flocculates with changes in pH. In animals, progressive fibrosis of the pancreatic tissue occurs after injection of neoprene in the main pancreatic duct, leaving islets well vascularized and functioning for prolonged periods. Using this technique, three severely diabetic patients received a cadaver segmental pancreatic allograft. Blood sugar returned to normal levels within the first hours or days after operation. All three grafts continue to function 1.5, 2, and 8 months, respectively, following transplantation. If these results are confirmed by further clinical experience, this method may be of considerable assistance in the treatment of severe diabetes by pancreatic transplantation.

The rat hepatic stearoyl-CoA desaturation decreased by 3.7-fold in streptozotocin-induced diabetes. Insulin treatment of diabetic rats increased the enzyme activity by 7-fold. In marked contrast to glucose administration, fructose feeding in diabetic rats resulted in 20-fold stimulation of stearoyl-CoA desaturation, although both carbohydrates stimulated stearoyl-CoA desaturation in normal rats. Measurement of the microsomal electron transfer components showed no significant changes in the NADH-cytochrome b5 reductase activity or in the concentration of cytochrome b5. However, the activity of the terminal desaturase changed in a parallel fashion as the amount of terminal desaturase reflect changes in the overall desaturation. Supplementation of various microsomes with the saturating amount of purified terminal desaturase resulted in the formation of similar amounts of catalytically active complex and increased the stearoyl-CoA desaturation to the same level suggesting that the changes in the amount of terminal desaturase reflect changes in the overall desaturation. The results support the suggestion that both insulin and the intermediates of carbohydrate metabolism are involved in the regulation of terminal desaturase.

Arteriosclerosis is caused by many factors. These pathogenic factors especially over-nutrition, nicotinabusus, deficiency of muscular exercise, muscular overstrain, emotional stress and concomitant basic diseases, especially arterial hypertension, diabetes mellitus and dyslipidemia are the most important points for preventive and therapeutical action. When possible the risk factors has to be eliminated, arterial hypertension, diabetes mellitus and dyslipidemia have to be treated orderly. In the pathogenesis of arteriosclerosis and atherosclerosis are known disturbances of the lipid metabolism, the blood coagulation and the metabolism of the arterial wall cells most important. Application of anticoagulants and lipid lowering medicaments did not come up to our expectations. Experiences with animal models and a double blind study (secondary prevention of myocardial infarction) have given good reason for recommending antirheumatic or as we like to say, mesenchyme suppressive drugs.
