The aim of this study is to evaluate the effects of 2-aminoethoxydiphenyl borate (2-APB) as an antioxidant and analyze biochemical and histopathologic changes in experimental ischemia-reperfusion (I/R) injury in rat ovaries.
Thirty female rats were utilized to create four groups. Group 1: I/R and 2-APB (2mg/kg); Group 2: I/R and 2-APB (4mg/kg); Group 3: I/R; Group 4: sham operation. Ovarian tissue and serum malondialdehyde, nitric oxide (NO) levels; ovarian tissue and serum total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI) were determined. In ovarian tissue samples histopathologic examination, immunoflourescence staining by TUNEL method was studied.
Tissue TOS, serum TOS, and OSI levels were elevated in I/R group. After treatment with 2-APB, tissue and serum TOS levels and OSI levels were markedly decreased. There was a significant difference in terms of tissue and serum NO levels between the sham group and I/R group. Elevation in tissue NO and serum NO levels were decreased after treatment with 2-APB. TUNEL-positive cell number gradually decreased with dose of 2-APB in groups 1 and 2.
Conservative treatment with 2-APB is beneficial for mitigation of I/R injury, and the ovarian protective effect of 2-APB appears to be mediated through its antiapopitotic and antioxidative effects.
本研究旨在评估2-氨基乙氧基二苯硼酸(2-APB)作为抗氧化剂的作用,并分析大鼠卵巢实验性缺血再灌注(I/R)损伤中的生化和组织病理学变化。
使用30只雌性大鼠创建四组。第1组:I/R和2-APB(2mg/kg);第2组:I/R和2-APB(4mg/kg);第3组:I/R;第4组:假手术。测定卵巢组织和血清丙二醛、一氧化氮(NO)水平;卵巢组织和血清总抗氧化状态(TAS)、总氧化状态(TOS)、氧化应激指数(OSI)。对卵巢组织样本进行组织病理学检查,采用TUNEL法进行免疫荧光染色研究。
I/R组组织TOS、血清TOS和OSI水平升高。用2-APB治疗后,组织和血清TOS水平以及OSI水平明显降低。假手术组和I/R组在组织和血清NO水平方面存在显著差异。用2-APB治疗后,组织NO和血清NO水平的升高有所降低。在第1组和第2组中,TUNEL阳性细胞数随2-APB剂量逐渐减少。
2-APB保守治疗有利于减轻I/R损伤,2-APB的卵巢保护作用似乎是通过其抗凋亡和抗氧化作用介导的。
