Description:

2-(3,4-Dihydroxyphenyl)ethanol has antioxidant properties; it is a potent specific inhibitor of lipoxygenase activities, it inhibits platelet 12-LO activity (IC50, 4.2 microM) and PMNL 5-LO activity (IC50, 13 microM) but not cyclooxygenase activity in cell-free conditions; it also inhibits 12-LO activity in intact platelets (IC50, 50 microM) and reduces leukotriene B4 production in intact PMNL stimulated by A23187 (IC50, 26 microM).

Hydroxytyrosol (2-(3,4-Dihydroxyphenyl)ethanol, (DPE), a phenolic compound present in olive oil, is known to have antioxidant properties. 

METHODS AND RESULTS:

The aim of this study was to investigate the effect of DPE on oxidative stress induced by cadmium injections (CdCl2 2.5 mg/kg body weight) in spleen and testes of adult male rats. Oxidative stress was evaluated by measuring lipid peroxidation by thiobarbituric acid reactive substances (TBARS) as well as superoxide dismutase (SOD) and catalase (CAT) activities in cytosol and mitochondria. We found that in spleen no TBARS formation was detected following CdCl2 injections; however, DPE induces decrease in TBARS level in treated and untreated rats. On the contrary, we observed that DPE showed no effect on cadmium-induced lipid peroxidation in testes. Cytosolic activities of SOD and CAT decreased significantly only in spleen, where DPE restores the values to the control levels. Noteworthy, mitochondrial activities of SOD and CAT were strongly reduced by cadmium treatment both in spleen and testes, and DPE was not be able to restore their activity. 

CONCLUSIONS:

Overall, the results from this study indicated that the DPE has different antioxidant efficiency in spleen and testis of cadmium intoxicated rats.
