This study explores the protective efficacy of Nigella sativa oil (NSO), Vitamin C, and E in countering the toxic effects of Aflatoxin M1 (AFM1) in neonatal Wistar rats. A total of 117 neonatal rats were randomized into 13 groups (A-M) and observed over 12 weeks. Group A served as the control, while the remaining groups were exposed to varying concentrations of AFM1, either alone or in combination with the supplements. Hematological parameters, including Packed Cell Volume (PCV), Red Blood Cells (RBC), Hemoglobin (HB), White Blood Cells (WBC), and liver enzyme activities, were measured using Microhematocrit Reader, Hemocytometer, Hemoglobinometer, and Spectrophotometer respectively. Histopathological assessments of liver tissues were conducted using staining techniques to assess cellular damage, inflammation, and fibrosis. The results demonstrated that simultaneous supplementation with NSO, Vitamin C, and E significantly improved PCV, HB, and RBC levels while reducing WBC counts and liver enzyme activities in comparison to AFM1-exposed groups. Notably, NSO effectively restored hematological parameters and facilitated liver tissue regeneration, even at higher concentrations of AFM1. In contrast, Vitamins C and E displayed protective effects predominantly at lower toxin levels. These findings suggest that NSO, in conjunction with Vitamin C and E, plays a pivotal role in mitigating the detrimental effects of AFM1 toxicity. NSO shows superior potential in reversing blood dyscrasia and liver damage. The study highlights the promising therapeutic utility of Nigella sativa oil as a natural remedy for alleviating aflatoxin-induced oxidative stress and organ damage, reinforcing its potential to safeguard public health against aflatoxin exposure.
本研究探讨了黑种草籽油(NSO)、维生素C和维生素E对新生Wistar大鼠黄曲霉毒素M1(AFM1)毒性的保护作用。总共117只新生大鼠被随机分为13组(A - M),并观察12周。A组作为对照组,其余各组单独或与补充剂联合暴露于不同浓度的AFM1。分别使用微量血细胞比容读数仪、血细胞计数器、血红蛋白仪和分光光度计测量包括血细胞比容(PCV)、红细胞(RBC)、血红蛋白(HB)、白细胞(WBC)在内的血液学参数以及肝酶活性。使用染色技术对肝组织进行组织病理学评估,以评估细胞损伤、炎症和纤维化。结果表明,与暴露于AFM1的组相比,同时补充NSO、维生素C和维生素E可显著提高PCV、HB和RBC水平,同时降低WBC计数和肝酶活性。值得注意的是,即使在较高浓度的AFM1情况下,NSO也能有效恢复血液学参数并促进肝组织再生。相比之下,维生素C和维生素E主要在较低毒素水平时显示出保护作用。这些发现表明,NSO与维生素C和维生素E联合使用在减轻AFM1毒性的有害影响方面起着关键作用。NSO在逆转血液恶病质和肝损伤方面显示出卓越的潜力。该研究突出了黑种草籽油作为一种天然药物减轻黄曲霉毒素诱导的氧化应激和器官损伤的有前景的治疗效用,增强了其保护公众健康免受黄曲霉毒素暴露影响的潜力。
