Ischaemia-reperfusion (I/R) injury is a serious problem subsequent to reperfusion treatment for ovarian torsion. The role of nitric oxide (NO) in ovarian I/R injury is debatable. The main focus of this study was to explore the protective role of L-arginine, a potent NO precursor, on ovarian I/R injury. Female Wistar rats were divided into three groups (n = 5). In the control group, only laparotomy was performed. In the I/R group, ischaemia and reperfusion were performed and no drug was given. In the I/R + arginine group, ischaemia was followed by reperfusion and 200 mg kg–1 L-arginine was injected 5 min before reperfusion. Concentration of malondialdehyde, NO and reduced glutathione, as well as activity of superoxide dismutase and catalase were analyzed. Hematoxylin and eosin-stained slides were microscopically examined for histological evaluation of the ovaries. Superoxide dismutase and catalase activity along with concentration of reduced glutathione and NO were significantly lower in the I/R group in comparison to the control group. Malondialdehyde concentration was significantly higher in the I/R group than in control group. These results were reversed with supplementation of L-arginine. Light microscopic examination revealed severe vascular congestion, edema, haemorrhage, and follicular degeneration in the ovary tissue. The extent of ovarian damage was much higher in the I/R group than in the I/R + L-arginine group. Treatment with L-arginine seems to have an ameliorating effect against oxidative stress in I/R injury in rat ovary. It considerably reduced the altered histological changes in the ovaries. Thus, it can be speculated that L-arginine might play a pivotal role as a potent therapeutic agent against ovarian torsion.
缺血-再灌注(I/R)损伤是卵巢扭转再灌注治疗后的一个严重问题。一氧化氮(NO)在卵巢I/R损伤中的作用尚存争议。本研究的主要重点是探讨l -精氨酸(一种有效的NO前体)对卵巢I/R损伤的保护作用。雌性Wistar大鼠分为3组(n = 5)，对照组仅开腹。I/R组进行缺血再灌注，不给药。I/R +精氨酸组缺血后再灌注，再灌注前5 min注射200 mg kg-1 l -精氨酸。分析了丙二醛、一氧化氮、还原性谷胱甘肽的浓度，以及超氧化物歧化酶和过氧化氢酶的活性。苏木精和伊红染色载玻片镜检卵巢组织学评价。与对照组相比，I/R组的超氧化物歧化酶和过氧化氢酶活性以及还原性谷胱甘肽和NO浓度均显著降低。I/R组丙二醛浓度显著高于对照组。这些结果与补充l -精氨酸相反。光镜检查显示卵巢组织有严重的血管充血、水肿、出血和卵泡变性。I/R组卵巢损伤程度明显高于I/R + l -精氨酸组。l -精氨酸对大鼠卵巢I/R损伤的氧化应激有改善作用。它大大减少了卵巢的组织学改变。因此，可以推测l -精氨酸可能作为一种有效的治疗卵巢扭转的药物发挥关键作用。
