Effect of lipopolysaccharide (LPS, 1.75 mg/kg), methyltriphenylphosphonium chloride (TPP, 50 nmol/kg) and mitoTEMPO (mT, 50 nmol/kg) on organ damage markers. An increase for few values is seen in the LPS + TPP group compared to the LPS group for all tissue damage markers. LDH showed significant difference between the LPS + TPP and all other groups. The LPS + mitoTEMPO seems to indicate beneficial effects of antioxidants (AOX) being lower than both the LPS and the LPS + TPP groups for all values measured; (a) aspartate aminotransferase (AST), (b) alanine aminotransferase (ALT), (c) lactate dehydrogenase (LDH), (d) urea, (e) creatinine (Crea) and (f) creatine kinase (CK). One-way analysis of variance (ANOVA), Fisher’s least significant difference (LSD), n = 3–8, mean ± SEM, * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001.
