[Effectiveness of replacement of renal function in diabetics].

The authors compared the survival of four groups of patients and of renal grafts: 1. diabetics after renal transplantation (24 subjects), 2. diabetics after transplantation of the kidney and pancreas (35 subjects), 3.

[The early phase of development of myocardial infarction in diabetics].

The authors evaluated retrospectively the course of the early stage of symptomatic myocardial infarction (IM) with regard to the incidence and character of infarction pain and the clinical course of IM during hospitalization at the coronary unit (CU) in a group of diabetic patients (D, n = 67) and a group of non-diabetic controls (ND, n = 63). In the group D there was a higher incidence of painless IM (D 7.5%, ND 0%, p less than 0.

Endocrine pancreatic secretion in patients after acute pancreatitis.

In 14 nonobese patients after acute pancreatitis and with normal oral glucose tolerance, the response of insulin, C-peptide, and pancreatic glucagon after 100 g of oral glucose was assessed. The curves of insulin and C-peptide were significantly raised compared with those of controls, and no difference was found between the response of patients with a negative (n = 8) and a positive (n = 6) family history of type II diabetes. The curves of pancreatic glucagon did not differ from those found in controls.

Beta-2-microglobulin release in mixed lymphocyte cultures.

Significantly more beta 2-m is released in MLCs than in control cultures of cells from one donor or in cultures of pooled irradiated cells from several donors. Beta 2-m release increases with cultivation time and depends on the intensity of stimulation. It is highest in three-way MLCs and lowest in one-way MLCs when cells of haploidentical individuals are cocultivated.

[Urinary excretion of catecholamines by the transplanted kidney].

In 88 patients after kidney transplantation (Tx) and in 30 healthy volunteers the urinary adrenaline, noradrenaline and dopamine excretion in 24 hours was examined. The results were calculated per values of glomerular filtration rate (Ccr). In patients after Tx an increased adrenaline excretion was found and its relative predominance over noradrenaline in urine, as it is the case in renal insufficiency.

Diffusion approximation of the neuronal model with synaptic reversal potentials.

The stochastic neuronal model with reversal potentials is approximated. For the model with constant postsynaptic potential amplitudes a deterministic approximation is the only one which can be applied. The diffusion approximations are performed under the conditions of random postsynaptic potential amplitudes.
