ABSTRACT

Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection. This study aimed to investigate the potential protective effect of the lungs in sepsis by modulating inflammatory and oxidative stress markers. Twenty-four adult male Swiss-albino mice, aged 8-12 weeks and weighing 20-30 g, were divided into four equal groups (n=6): sham (laparotomy only), CLP (laparotomy plus cecal ligation and puncture), vehicle (DMSO administered one hour before CLP), and Ticagrelor (50 mg/kg IP administered one hour before CLP). Tissue levels of pro-inflammatory and oxidative stress markers in the lung were assessed using ELISA. F2 isoprostane levels were significantly higher in the sepsis group (p<0.05) compared to the sham group, while Ticagrelor significantly decreased the inflammatory and oxidative stress markers compared to the sepsis group. All mice in the sepsis group had considerable (p=0.05) lung tissue damage, but Ticagrelor considerably decreased lung tissue injury (p=0.05). Furthermore, Ticagrelor was found to reduce tissue cytokine levels of the lung (IL-1, TNF a, IL-6, F2 isoprostane, GPR 17, MIF) in male mice during CLP-induced polymicrobial sepsis by modulation of pro-inflammatory and oxidative stress cascade signaling pathways.

ABSTRACT

OBJECTIVE: Aim: The goal of this experiment was to examine if Clopidogrel might protect the lungs during sepsis by modulating the inflammatory and oxidative stress markers. PATIENTS AND METHODS: Materials and Methods: Twenty-four adult male Swiss-albino mice aged 8-12 weeks, with a weighing of 20-30 g, were randomized into 4 equal groups (n=6): sham (Laparotomy without cecal ligation and puncture [CLP]), CLP (laparotomy plus CLP), vehicle (DMSO 1 hour prior to CLP), Clopidogrel (50 mg/g IP 1 hour before to CLP). ELISA was used to assess Lung tissue levels of pro-inflammatory and oxidative stress markers. RESULTS: Results: F2 isoprostane levels were significantly higher in the sepsis group (p<0.05) in comparison with sham group, while Clopidogrel was considerably lower (p<0.05) in the inflammatory and oxidative stress markers in comparison to sepsis group. Histologically, all mice in the sepsis group had considerable (p=0.05) lung tissue damage, but Clopidogrel considerably decreased lung tissue injury (p=0.05). CONCLUSION: Conclusion: Clopidogrel was found to reduce lung tissue cytokine concentrations (IL-1, TNF a, IL-6, F2 isoprostane, GPR 17, MIF) in male mice during CLP-induced polymicrobial sepsis by modulation of pro-inflammatory and oxidative stress cascade signaling pathways, to the best of our abilities, no study has looked at the effect of Clopidogrel on MIF levels.
