  • Title: [Role of interleukin-6 (IL-6) in the pathogenesis of combined radiation/thermal injuries].

    Journal: Radiats Biol Radioecol; 2004; 44(4):398-402. PubMed ID: 15455667.
    Abstract:
    Combined injury such as whole body gamma-irradiation at the dose of 7 Gy+10% body surface full-thickness thermal burn were investigated in (CBA x C57BL6)F1 mice. Enhanced level of IL-6 in mice serum at 6-24 hs following combined injury was established. The potential inhibiting activity of pentoxifylline (POF) as an influence to IL-6 levels, and measure of several acute phase response signs has been evaluated. It was established, that single POF injection don't modify IL-6 production, don't change leukocytosis and early hyperfermentemia (as alaninaminotransferase levels indicated). But serum albumin content was increased after preliminary POF administration to mice with combined injury. On the other side, mouse anti-IL-6 monoclonal antibodies administration increased 30-days animal survival up to 60% while 100% lethality was registered in untreated mice. Possible anti-inflammatory inactivity reasons of POF under combined injury conditions are discussed in this article, and important role of IL-6 hyperproduction in combined injury outcomes burden is suggested.
