The acute inflammatory answer is a manifestation of the organism triggered by an infectious or non-infectious taunting. Predisposal factors are, for instance: bacteria, viruses, amongst other microorganisms or traumas. It is an internal survival mechanism. The development of a cascade of immunological events in an attempt of destroying an aggressive agent, with cardiologic, hemodynamic, respiratory, renal, endocrine, metabolic, gastrointestinal and hematological alterations occurs determining a syndrome clinic case. Vascular and immunological alterations trigger a counter balance inflammatory response. Recent researches using a specific derived fraction of the natural gum of Hevea brasiliensis rubber tree, called Hev b 13, has shown induction capability to synthesize interleukin 10 (IL-10) in vitro, stimulating the anti-inflammatory response that may result in homeostasis. These evidences are assessed with high mortality sepis induction, after surgical procedure with gastric, intestinal and pancreatic damaging and strain infusion of Acinetobacter baumanni of resistance profile to multiple antibiotics tested. In dose 0,5 mg/kg of Hev b 13 solution, subcutaneous, similarities were observed in the survival of animals treated with this solution and the control group, treated with 1 ml of SF0, 9% (p= 0,8106). The laboratorial analysis, on the other hand, showed total leukocytes reckoning (p = 0,0207) and total lymphocyte (p= 0,0032) with statistically significant differences. In further counting there was no significant difference (p>0,05). The Hev b 13 solution may lead to the induction of reducing the amplification of immunological cellular cascade, reducing the production of total leukocytes and lymphocytes, with effect over the immunological response, anti-inflammatory effect. The experiment induced synthesis of interleukin-10 (IL-10) and tumor necrosis factor (TNF). Rats receiving Hev b 13, lung tissue showed lesser involvement of inflammatory cells.
