Thus, overcoming the side effects of CPZ is of great importance. Because agmatine (AGM) can act as a free radical scavenger, it is an interesting compound as an adjunct to CPZ therapy. The aim of our study was to investigate the enzymatic parameters of oxidative stress in the hippocampus and striatum of rats after CPZ treatment, and the potential protective effects of AGM. Rats were injected as follows with (i) 1 mL/kg b.w. saline; (ii) a single intraperitoneal (i.p.) dose of CPZ (38.7 mg/kg); (iii) CPZ (38.7 mg/kg) and AGM (75 mg/kg); (iv) AGM (75 mg/kg). CPZ induced an increase in superoxide anion radical (O<sub>2</sub><sup>•-</sup>) concentration, while the activities of the antioxidant enzymes, superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and glutathione reductase (GR), were lowered in both the hippocampus and striatum. Cotreatment with CPZ and AGM protected the examined brain structures by reversing the antioxidant enzyme activities to the control values. Following CPZ treatment, the effects were more pronounced for SOD and GPx in the hippocampus, and for SOD, CAT and GPx in the striatum. The full effect of restored superoxide production was achieved in the striatum, which points to the role of CAT. The obtained results suggest that CPZ in combination with AGM may be considered as a new treatment strategy.</p> ER -
