Antioxidant status in plasma, erythrocytes and platelets following the use of antihemostatic drugs and vasodilatation supplements

U istraživanju se pratila promjena antioksidativnog statusa u plazmi, trombocitima i eritrocitima krvi štakora nakon primjene antihemostatskih lijekova i vazodilatacijskih suplemenata zasebno i u kombinaciji. U pokusu je bilo 9 skupina pod tretmanom i jedna kontrolna skupina. Skupine pod tretmanom bile su skupine: 1. Ginko, 2. Vulkan, 3. Salicilna kiselina , 4. Varfarin, 5. Vulkan+varfarin, 6. Vulkan + salicilna kiselina, 7. Ginko + varfarin, 8. Ginko + salicilna te 9. Ginkalert. Uz 9 skupina pod tretmanom bila je i kontrolna skupina 0. Životinje su tretirane kroz razdoblje od 28 dana, prema preporučenom toksikološkom protokolu OECD 407 nakon čega su žrtvovane i uzeti uzorci krvi. Nakon centrifugiranja i odvajanja komponenti krvi izmjereni su markeri antioksidativnog sustava: superoksid dismutazu (SOD), glutation (GSH), katalazu (CAT) te malondialdehid (MDA). Ovo istraživanje je potvrdilo da postoji niz mogućih interakcija između vazodilatacijskih suplemenata i primjene antihemostatskih lijekova, koje dovode do velikih promjena u antioksidativnom statusu organizma. Stoga je potrebno ograničiti istovremenu primjenu antihemostatika i vazodilatacijskih suplemenata prehrani kako bi spriječili moguće štetne posljedice.The study monitored the changes in antioxidant status of plasma, platelets and red blood cells of rat blood after administration of antihemostatic drugs and vasodilating supplements alone and in combination. The experiment was composed of 9 groups under treatment and one control group. The groups under treatment were the groups: 1. Ginkgo, 2. Vulkan, 3. Salicilna, 4. Warfarin, 5. Vulkan+warfarin, 6. Vulkan+salicilna, 7. Ginko + warfarin, 8. Ginko + and 9. Ginkalert. Nine groups under treatment and the control group animals were treated over a period of 28 days, according to the recommended OECD 407 toxicological protocol. The animals were sacrificed and blood samples were taken. After centrifugation and separation of blood components the markers of antioxidant system, superoxide dismutase (SOD), glutathione (GSH), catalase (CAT) and malondialdehyde (MDA) were measured. This research has confirmed that there are a number of possible interactions between applying vasodilating supplements and antihemostatic drugs, which led to big changes in the antioxidant status of the organism. Obtained results suggest it is necessary to confine the simultaneous application of antihemostatic drugs and vasodilating supplements in order to prevent possible harmful effects
