Abstract
- Cell culture K562 samples were treated with fullerenol (C6o(OH)24) at a concentration of 10 nmol/mL and thereafter irradiated with X-rays (24Gy). The activity of gamma-glutamyltransfrease (γ-GT), total superoxide-dismutase (SOD) and glutathion-peroxidase (GSH-Px) was determined 1, 24 and 48 hours after irradiation. Irradiation induces an increase in the activity of all the investigated enzymes. Fullerenol in the applied dose decreased the γ-GT activity 24 and 48 h after irradiation. The total SOD activity is increased in both pretreated groups except in the irradiated group at the 48th hour. Treatment with fullerenol before irradiation increased GSH-Px activity in irradiated groups and decreased it in the control groups. U uzorcima ćelijske kulture humane eritroleukemije (K562) ozračenim X-zracima doze 24 Gy i predtretiranim fulerenolom (C60(OH)24) koncentracije 10 nmol/mL određivana je aktivnost gama-glutamiltransferaze (γ-GT), ukupne superoksid-dismutaze (SOD) i glutation-peroksidaze (GSH-Px) 1, 24 i 48 sati nakon zračenja. Iradijacija povećava aktivnost sva tri ispitivana enzima. U 24-om i 48-om satu nakon zračenja zapaža se sniženje aktivnosti γ-GT u grupama predtretiranim fulerenolom. Fulerenol utiče na povišenje aktivnosti SOD u obe tretirane grupe, osim u grupi ozračenih uzoraka u 48-om satu gde je došlo do sniženja aktivnosti. Predtretman fulerenolom u zračenim grupama povećava, a u neozračenim eksperimentalnim grupama snižava aktivnost GSH-Px. null
