[APUD- and RAA- regulatory systems in acute radiation injury]. / APUD- i RAA-sistemy reguliatsii pri ostrom radiatsionnom porazhenii.

An experimental morpho-functional assessment of rat APUD and RAA systems status in acute radiation injury (cerebral form) was performed. The named regulatory systems were found to display an actual momentary post-exposure reaction, followed by subsequent functional changes of a distinct phase character. The latter were shown to determine in many respects the clinical picture and in some cases the outcome of the disease.
