Abstract : Cytokine production by different kinds of macrophages, and serum IL-1Beta, TNF-alpha, IL-6, IL-3, and GM-CSF levels, were evaluated in a murine model of combined injury (whole body irradiation + thermal burn). The results were compared with systemic cytokine responses to radiation or burn alone. The obtained data suggest that increased IL-6 levels may play an important role in the pathogenesis of combined injury. Single injection of extract from Serratia marcescens (Imuvert) or synthetic trehalose dicorynomy-colate improved hematological status, enhanced the serum IL-6 levels, but did not promote survival in mice. On the other hand, heat-killed Lactobacillus acidophilus demonstrated a weak effect on cytokine response, did not improve severe hematological disorders, but none the less increased 30 days survival in mice up to 100%, versus 50% in the untreated group.
