  • Title: [Effects of modulators of cytokine levels on mice and rats survival under combined radiation/thermal injuries].
    Author: Budagov RS, Ul'ianova LP.
    Journal: Radiats Biol Radioecol; 2004; 44(4):392-7. PubMed ID: 15455666.
    Abstract:
    The influence of LPS-induced increasing of proinflammatory cytokine production inhibitors (pentoxifylline--POF, glycine--G), Kupffer cells elimination (gadolinium chloride--GC) and monoclonal anti-IL-6 antibodies on 30-days survival, mean survival time and probability of mortality within animals under combined radiation/thermal injury were evaluated. Experiments were carrying out on mice (whole body gamma-irradiation at the dose of 7 Gy + 10% body surface full-thickness thermal burn) and rats (gamma-irradiation at the dose of 7.5 Gy + 15% body surface burn). It was established that POF, G and GC didn't modify survival. Mouse anti-IL-6 monoclonal antibodies administration 1 h prior and 1, 2, 3 days after combined injury increased 30-days animal survival up to 60% in each group and up to 90% while antibodies were injected in 6, 7, 8 days after combined injuries; 100% lethality was registered in untreated mice. Possible anti-inflammatory inactivity reasons of modulators of cytokine levels under combined injury conditions are discussed.
