Trauma patients, who are exposed to bacterial infections i.e. traumatic accidents are at risk to be exposed to so-called “LUCOHAS” (mortal LPSUPR- Calcium Overload Hyper- Activation System). The essential components of LUCOHAS signaling pathway are consist of 4 main key players. The aim of this study is to evaluate induction of inflammatory processes and assess the administration effects at molecular and tissue cytokine changes, in an innovative prepared model system, in vivo. Methods: The LPS was extracted from patients’ burned wounds after Pseudomonas aeruginosa isolation (hLPS), with informed consent. The male c57/BL6 mice divided into 6 groups: 1. Two controls, one received nothing another sterile pyrogen-free normal saline, 3. hLPS (3 mg/kg/ intraperitoneal), 4. hLPS+ Dantrolene sodium (Dan)-calcium release inhibitor (CCI1) (40 mg/kg), 5. 2-aminomethyl phenyl borinate (2APB)- CCI2 (1 mg/kg) and 6. hLPS+CCI1/CCI2. Subsequently, mice livers were extracted for evaluating the X-box Binding Protein 1 gene (XBP-1) Splicing as a marker of the adaptive UPR activation and cytokine assay after 2, 8 and 24 hrs. Results: Compared to the controls, the IL-1β levels in hLPS group significantly increased after 8 and 24 h injection (P
