Aim of the study was to evaluate the effects of high dose methylprednisolone on experimental ovarian torsion-detorsion injury in rats. Twenty-two Sprague-Dawley rats were randomly divided into three groups. Group 1 (ischemia group, 8 rats) were subjected to left adnexal torsion for 2 h but received no treatment. Group 2 (methylprednisolone group, 8 rats) were subjected to left adnexal torsion for 2 h and received methylprednisolone (30 mg/kg, administered intraperitoneally) at the end of a 2-hour ischemic period followed by 24-hour reperfusion. Group 3 (control group, 6 rats) underwent a sham operation with no adnexal torsion and no treatment. Serum malondialdehyde (MDA), ischemia-modified albumin (IMA), total oxidant status (TOS) and tissue MDA levels were increased in Group 1 rats; total antioxidant status (TAS) levels and oxidative stress index (OSI) were significantly decreased compared with rats in Groups 2 and 3 (p < 0.05). MDA, IMA, TOS and tissue MDA levels were lower and TAS levels and OSI were higher in Group 3 compared to Group 2. Ovarian damage scores in Group 1 were significantly higher compared with Groups 2 and 3 (p < 0.05). This study demonstrated that high dose methylprednisolone reduces ovarian ischemia/reperfusion injury.
本研究的目的是评估高剂量甲泼尼龙对大鼠实验性卵巢扭转-复位损伤的影响。22只Sprague-Dawley大鼠被随机分为三组。第1组(缺血组,8只大鼠)接受左侧附件扭转2小时,但未接受治疗。第2组(甲泼尼龙组,8只大鼠)接受左侧附件扭转2小时,并在2小时缺血期结束时腹腔注射甲泼尼龙(30mg/kg),随后进行24小时再灌注。第3组(对照组,6只大鼠)进行假手术,不进行附件扭转且不接受治疗。第1组大鼠血清丙二醛(MDA)、缺血修饰白蛋白(IMA)、总氧化剂状态(TOS)和组织MDA水平升高;与第2组和第3组大鼠相比,总抗氧化剂状态(TAS)水平和氧化应激指数(OSI)显著降低(p<0.05)。与第2组相比,第3组的MDA、IMA、TOS和组织MDA水平较低,TAS水平和OSI较高。第1组的卵巢损伤评分与第2组和第3组相比显著更高(p<0.05)。本研究表明,高剂量甲泼尼龙可减轻卵巢缺血/再灌注损伤。
