The aim of the study is to investigate the effects of Protocatechuic Acid (PCA), which is an antioxidant, anti-inflammatory and anti-apoptotic agent, on ovarian tissue and ovarian reserve against ischemia-reperfusion (IR) injury in a rat ovarian torsion model.
Reactive oxygen radicals cause histopathological changes in the ovarian tissue during the reperfusion phase. PCA may have protective effects on ovarian tissue and reserve due to its antioxidant and antiapoptotic properties.
A total of 24 Wistar adult female rats were divided into 3 groups as the control (sham operation, n = 8), IR (Ischemia-Reperfusion, n = 8), and IR+PCA (Ischemia-Reperfusion + 80 mg/kg protocatechuic acid, n = 8). The IR and IR + PCA groups underwent 3 hours of ischemia followed by 3 hours of ovarian reperfusion. Protocatechuic acid (80 mg/kg) was administered to the IR+PCA group 30 minutes before reperfusion. After reperfusion, the ovaries were removed for histopathological and biochemical examination.
Histopathological score and TUNEL+ cell count were significantly lower and AMH expression level was significantly higher in the IR+PCA group when compared to the IR group (p <0.05). However, in the comparison of the follicle counts, there was no statistically significant difference between all groups. Due to the increase in antioxidant activity, the MDA levels were found to be significantly lower in the IR+PCA group compared to the IR group (p < 0.05).
Protocatechuic acid may be an effective antioxidant in protecting ovarian tissue and follicle reserve against IR injury of the ovary (Tab. 1, Fig. 4, Ref. 36).
本研究旨在探讨原儿茶酸(PCA),一种具有抗氧化、抗炎和抗凋亡作用的药物,在大鼠卵巢扭转模型中对卵巢组织及卵巢储备功能抗缺血再灌注(IR)损伤的影响。
活性氧自由基在再灌注阶段会导致卵巢组织发生组织病理学改变。PCA因其抗氧化和抗凋亡特性,可能对卵巢组织及储备功能具有保护作用。
将24只成年Wistar雌性大鼠分为3组:对照组(假手术,n = 8)、IR组(缺血再灌注,n = 8)和IR+PCA组(缺血再灌注 + 80 mg/kg原儿茶酸,n = 8)。IR组和IR+PCA组经历3小时缺血,随后进行3小时卵巢再灌注。在再灌注前30分钟给IR+PCA组注射原儿茶酸(80 mg/kg)。再灌注后,取出卵巢进行组织病理学和生化检查。
与IR组相比,IR+PCA组的组织病理学评分和TUNEL+细胞计数显著降低,AMH表达水平显著升高(p <0.05)。然而,在卵泡计数比较中,所有组之间无统计学显著差异。由于抗氧化活性增加,IR+PCA组的MDA水平与IR组相比显著降低(p <0.05)。
原儿茶酸可能是一种有效的抗氧化剂,可保护卵巢组织和卵泡储备免受卵巢IR损伤(表1,图4,参考文献36)。
