[Transcranial electrical stimulation activates the reparative regeneration and insulin-producing function of beta-cells in alloxan-induced diabetic rats].

In alloxan-induced diabetic rats, it was demonstrated that transcranial electrical stimulation of the brain endorphinergic structures activated the reparative regeneration of the damaged beta-cells of the Langerhans pancreatic islets. This was estimated on the histological sections of pancreas with hematoxylin-eosin staining. Several small newborn islets were found to originate from pancreatic progenitor cells. After transcranial electrical stimulation of insulin granules, beta-cells (Gomori's staining) were observed as an indication of the restoration of the insulin production. Correspondingly the increase of the blood insulin level was estimated by immune-enzyme method. The dynamics of the plasma insulin increase had a significant negative correlation with decrease of the blood glucose level. The glucose-lowering action of the transcranial electrical stimulation in alloxan-induced diabetic rats seems to be based on stimulation of the regeneration of damaged beta-cells with the restoration of their insulin production.
