The purpose of this study was to assess selective inflammatory (C-Reactive Protein, CRP) and oxidative stress markers [Paraoxonase-1 (PON1), cupric reducing antioxidant capacity (CUPRAC), ferric reducing antioxidant power (FRAP), cholinesterase, and oxytocin in serum and cerebrospinal fluid (CSF) samples of dogs with different types of epilepsy.<h4>Methods</h4>There were four groups of dogs; A: healthy controls; B: idiopathic epilepsy receiving antiepileptic medication; C: idiopathic epilepsy without antiepileptic medication; and D: structural epilepsy. The gene discussed is OXT; the disease is structural epilepsy.
