Objectives:  To determine the effect of royal jelly (RJ) on the oxidant-antioxidant balance in rats with N-methyl-N-nitrosourea (MNU) induced breast cancer and to compare this with the chemotherapeutic agent paclitaxel.    Material and methods:  Fifty-six female Sprague Dawley rats were divided into five groups. Except control group (n=8, Group I) others received MNU (50 mg/kg, a single dose, i.p.) to develop breast cancer: Group II (n=8) untreated, Group III (n=7) treated with paclitaxel (15 mg/kg/week, 3 times, i.p.), Group IV (n=7) with RJ (by oral gavage, 100 mg/kg/day, for 30 days), and Group V (n=7), with paclitaxel+RJ. At the end of 30 days, histopathological and biochemical parameters were evaluated in breast tissues.    Results:  Levels of protein carbonyl (PC) and 8-hydroxy-deoxyguanosine (8-OHdG) were higher in Group V than in Group II while malondialdehyde (MDA) levels were lower in groups IV and V compared to Group II (p&lt;0.05). Levels of catalase (CAT) in Group V and glutathione (GSH) in Group III were higher than Group II (p&lt;0.05). Glutathione peroxidase (GPx) and superoxide dismutase (SOD) levels did not significantly different. Decreasing effect of RJ on CA15-3 levels was relevant to histopathological results.    Conclusion:  Although RJ (with or without paclitaxel) had increasing effect of antioxidant status it was insufficient to reduce oxidative stress in breast cancer.
