The aim of this study was to evaluate total antioxidant capacity (TAC) and biomarkers of lipid and protein peroxidation in the blood serum of dogs with benign prostatic hyperplasia (BPH). The study was conducted on 36 intact male dogs of various breeds. The dogs were assigned to two groups: BPH group (n = 18) and non-affected group (n = 18). Blood samples were collected from the cephalic vein. The antioxidant status of the serum was assessed using TAC. The levels of bityrosine, formylkynurenine and SH-groups were used as protein peroxidation biomarkers and the level of radical cations of N,N-diethyl-paraphenylene diamine (RC-DEPPD) was used as a marker for lipid peroxidation. TAC and the concentrations of SH-groups and RC-DEPPD in the serum were determined spectrophotometrically, the concentrations of bityrosine and formylokynurenine, were determined using spectrofluorimetric methods. The mean value of TAC in the serum was significantly lower (P = 0.01) in BPH dogs than in non-affected dogs (3.10 ± 0.56 vs 4.20 ± 1.60 μmol/g protein). Mean levels of protein and lipid oxidation biomarkers showed a trend towards oxidative imbalance, but there were no statistically significant differences between dogs with BPH and controls (P > 0.05). In conclusion, significantly lower serum TAC in dogs with BPH compared to non-affected dogs suggests a potential involvement of oxidative stress in the pathogenesis of BPH in dogs. More studies are needed to clarify the role of oxidative stress in the development of BPH in dogs.

良性前列腺增生犬的氧化应激生物标志物

本研究的目的是评估患有良性前列腺增生症 (BPH) 的犬血清中的总抗氧化能力 (TAC) 以及脂质和蛋白质过氧化的生物标志物。该研究是在 36 只不同品种的完整雄性狗身上进行的。这些狗被分配到两组:BPH 组 (n = 18) 和未受影响的组 (n = 18)。从头静脉采集血样。使用TAC评估血清的抗氧化状态。二酪氨酸、甲酰犬尿氨酸和 SH 基团的水平用作蛋白质过氧化生物标志物,N,N-二乙基对苯二胺 (RC-DEPPD) 的自由基阳离子水平用作脂质过氧化的标志物。通过分光光度法测定血清中的 TAC 和 SH 基团和 RC-DEPPD 的浓度,二酪氨酸和甲酰犬尿氨酸的浓度,使用荧光分光光度法测定。BPH 犬血清中 TAC 的平均值显着低于未患病犬 (3.10 ± 0.56 vs 4.20 ± 1.60 μmol/g 蛋白质) (P = 0.01)。蛋白质和脂质氧化生物标志物的平均水平显示出氧化失衡的趋势,但 BPH 犬和对照组之间没有统计学显着差异(P > 0.05)。总之,与未受影响的狗相比,患有 BPH 的狗的血清 TAC 显着降低表明氧化应激可能参与了狗 BPH 的发病机制。需要更多的研究来阐明氧化应激在犬 BPH 发展中的作用。60 μmol/g 蛋白质)。蛋白质和脂质氧化生物标志物的平均水平显示出氧化失衡的趋势,但 BPH 犬和对照组之间没有统计学显着差异(P > 0.05)。总之,与未受影响的狗相比,患有 BPH 的狗的血清 TAC 显着降低表明氧化应激可能参与了狗 BPH 的发病机制。需要更多的研究来阐明氧化应激在犬 BPH 发展中的作用。60 μmol/g 蛋白质)。蛋白质和脂质氧化生物标志物的平均水平显示出氧化失衡的趋势,但 BPH 犬和对照组之间没有统计学显着差异(P > 0.05)。总之,与未受影响的狗相比,患有 BPH 的狗的血清 TAC 显着降低表明氧化应激可能参与了狗 BPH 的发病机制。需要更多的研究来阐明氧化应激在犬 BPH 发展中的作用。与未受影响的狗相比,患有 BPH 的狗的血清 TAC 显着降低表明氧化应激可能参与狗的 BPH 发病机制。需要更多的研究来阐明氧化应激在犬 BPH 发展中的作用。与未受影响的狗相比,患有 BPH 的狗的血清 TAC 显着降低表明氧化应激可能参与狗的 BPH 发病机制。需要更多的研究来阐明氧化应激在犬 BPH 发展中的作用。
