The current study presents the bisphenol A exposure and the ameliorative effects of Adiantum capillus-veneris on testicular toxicity induced by bisphenol A. Adult male albino rats were divided into five groups of five animals each: A (control), B (vehicle control), C (toxic), D (protective), and E (ameliorative) were served distilled water, olive oil, bisphenol A (BPA) at 100 mg/kg body weight, A. capillus-veneris plant extract at 25 mg/kg body weight, and BPA + A. capillus-veneris, respectively. All of the doses were administered orally for 15 days, and the rats were then sacrificed. Blood samples for the testosterone assay and both testes were collected for histological examination. The body weight, paired testes weight, relative tissue weight index, Johnsen scoring of tubules, and level of serum testosterone decreased in BPA-treated rats. Similarly, histological examination of the testes in BPA-treated animals revealed a lower number of Leydig cells, an irregular basement membrane, sloughing of germinal layers, vacuolization, a lower number of spermatocytes, and debris in the lumen. However, co-administration of A. capillus-veneris with BPA increased the total antioxidative capacity (330.82 ± 22.46 μmol/mg protein) of the testes and restored the serum testosterone level (1.70 ng/ml); histological features showed restoration in the stages of spermatogenesis. Conclusively, A. capillus-veneris plant extract overcomes the estrogenic effects of BPA on the reproductive system of rats and protects rats' testes against BPA-induced injury/damage via an antioxidative mechanism that appears to be conciliated.
当前的研究介绍了双酚 A 暴露情况,以及铁角蕨对双酚 A 诱导的睾丸毒性的改善作用。成年雄性白化大鼠被分为五组,每组五只:A(对照组)、B(溶剂对照组)、C(毒性组)、D(保护组)和 E(改善组),分别给予蒸馏水、橄榄油、双酚 A(BPA)100mg/kg 体重、铁角蕨植物提取物 25mg/kg 体重和 BPA+铁角蕨。所有剂量均经口给药 15 天,然后处死大鼠。采集血液样本用于检测睾酮水平,并采集双侧睾丸进行组织学检查。BPA 处理组大鼠的体重、配对睾丸重量、相对组织重量指数、管腔的约翰森评分和血清睾酮水平均降低。同样,BPA 处理动物睾丸的组织学检查显示,Leydig 细胞数量减少,基膜不规则,生殖层脱落,空泡化,精母细胞数量减少,管腔中有碎片。然而,铁角蕨与 BPA 共同给药增加了睾丸的总抗氧化能力(330.82±22.46μmol/mg 蛋白),并恢复了血清睾酮水平(1.70ng/ml);组织学特征显示生精阶段得到了恢复。总之,铁角蕨植物提取物克服了 BPA 对大鼠生殖系统的雌激素作用,并通过抗氧化机制保护大鼠睾丸免受 BPA 诱导的损伤/损害,这种机制似乎得到了缓解。
