the effects of resistance training and berberine chloride supplementation on oxidative stress markers in the cerebellum tissue of diazinon-poisoned rats

Background: diazinon is an insecticide from the organophosphorus group, which can increase the oxidative stress in the body. it has been established that training and antioxidant supplementation can improve oxidative stress system by decreasing malondialdehyde (mda); meanwhile, increasing the activities of antioxidant enzymes, including superoxide dismutase (sod), glutathione peroxidase (gpx), and catalase (cat). objectives: the aim of this study was to investigate the effect of resistance training (rt) and berberine chloride (bc) supplementation on oxidative stress indices in the cerebellum tissue of diazinon-poisoned rats. methods: fifty-six wistar rats were divided into seven groups (n = 8), including resistance training (rt) (each session 2 sets of 6 repetitions, each one required 8 to 12 active movements with intensity of 10% - 50% of body weight, 3 sessions per week), bc2 (bc: 2 mg/kg), bc15 (bc: 15 mg/kg), rt + bc2, rt + bc15, diazinon, and control. mda, sod, and cat were measured in the cerebellum tissue. results: rt and bc significantly reducedmdaprotein levels (p < 0.01), while increased sod protein levels (p < 0.01) and cat protein levels (p < 0.01) in the cerebellum tissue of diazinon-poisoned rats; rt with bc had interactive effects on decreasing mda (p < 0.01), while increasing sod (p < 0.01) and cat protein levels (p < 0.01). also, the consumption of 15 mg/kg bc rather than 2 mg/kg bc significantly increased sod protein levels (p = 0.02). conclusions: it seems that rt combination with bc has interactive effects on the improvement of oxidative stress markers in the cerebellum tissue of diazinon-poisoned rats.
