[Variant of the Hodgkin-Huxley model with a reduced number of parameters]. / Variant modeli Khodzhkina-Khaksli s sokrashchennym chislov parametrov.

The time constants of variations in sodium and potassium conductances of neural cell membrane have been investigated as a function of transmembrane potential. It is shown that the dependences can be described by the model of self-organization and self-regulation in open dynamic systems reported early. This approach has two advantages over the empirical formulae by Hodgkin and Huxley: 1) the number of parameters to be defined is substantially reduced, which simplifies modeling of real cells, and 2) the model involves a particular mechanisms by which the transmembrane potential regulates the time constants of variations in membrane conductance, which can promote further development of theoretical conceptions of the action potential generation process.

[Isolated amyloidosis of the islands of Langerhans and diabetic mellitus]. / Izolirovannyi amiloidoz ostrovkov podzheludochnoi zhelezy i sakharnyi diabet.

One observation of isolated amyloidosis of the insular apparatus of the pancreas followed by the development of diabetes mellitus and diabetic microangiopathy in various organs is described. Total amyloid involvement of all insular apparatus is pointed out.
