Sažetak

Cilj ovog istraživanja bio je utvrditi djelovanje 150 mg/L natrijevog fluorida (NaF) na redoks-status i koncentracije esencijalnih elemenata [bakar (Cu), željezo (Fe) i cink (Zn)] u krvi, jetri, bubrezima, mozgu i slezeni Wistar štakora te mogući zaštitni učinak selena (Se) od toksičnosti prouzročene fluoridom (F-). Mužjaci Wistar štakora nasumično su razvrstani u četiri skupine (n=5), nakon čega su 28 dana konzumirali običnu vodu ili vodu s otopinom NaF 150 mg/L, NaF 150 mg/L + Se 1,5 mg/L ili Se 1,5 mg/L. Izloženost fluoridu dovela je do poremećaja redoks-parametara i koncentracija istraživanih biometala. Utvrđene su povišene razine superoksid aniona (O2.-) i malondialdehida (MDA) u krvi i mozgu, smanjena aktivnost superoksid dismutaze (SOD1) u jetri te njezin porast u mozgu i bubrezima. Nadomjesni Se u kombinaciji s NaF pozitivno je utjecao na razine MDA, SOD1 i O2.- u krvi, mozgu i bubrezima, a sâm Se smanjio je razine SH skupina u jetri i bubrezima. Izloženost fluoridu uzrokovala je sniženje, ali i porast koncentracija biometala. Nužna su dodatna istraživanja kako bi se ispitali antioksidacijski učinci Se na toksičnost izazvanu F-.
