Experimental procedure. A total of 75 rats were randomly divided into five groups of 15 animals each and were orally treated with distilled water (dH2O, 2 mL/kg/day), Tualang honey (TH, 1 g/kg/day), or ubiquinol (QH, 0.2 g/kg/day) throughout the experimental period. Two weeks after these treatments, the rats were injected with saline (1 mL/kg/week) or PQ (PQ, 10 mg/kg/week) once a week (open circles) for four consecutive weeks. A week after the last injection, the rats were sacrificed for biochemical (n = 8) or immunohistochemical (IHC, n = 7) analyses.
