Evaluation of psychoemotional status of rats after brain injury and systemic transplantation of mesenchymal stem cells.

We studied the effects of systemic transplantation of mesenchymal stem cells obtained after culturing of autologous bone marrow on psychophysiological status of Wistar rats after diffuse brain trauma. Two months after systemic injection of mesenchymal stem cells we observed a decrease in manifestations of emotional behavioral reactions (anxiety and excitability) and shortening of the time of realization of drinking behavior in a T-maze. A significant positive effect of systemic transfusion of mesenchymal stem cells on avoidance conditioning in a shuttle box was observed 3 months after brain injury.

Medical response to radiation incidents and radionuclear threats.

Events that expose people to radiation are rare, but the threat of radiation injury is increasing. Doctors should know how to recognise and manage suspected exposure or contamination

Mortality among the Chernobyl emergency workers: estimation of radiation risks (preliminary analysis).

This paper presents results of the analysis of mortality among Chernobyl accident emergency workers who are resident in Russia. The analysis is based on information for the cohort of emergency workers (males) from six regions of Russia including 65,905 persons with documented external doses in the range 0.005-03 Sv.
