Metabolic syndrome is a complex of metabolic disorders characterized by oxidative stress which compromises cell functions and entails multiple organs pathologies. We investigated the therapeutic and protective potential of Adansonia digitata fruit -a potent antioxidant- in high sugar/high fat diet-simulated metabolic syndrome in Wistar rats. 42 male rats (140-200 g) were randomly divided into 7 groups. G1 was kept on standard laboratory diet (SLD) for all 9 weeks (negative control). 5 groups were fed high Sugar/high fat diet for 6 weeks then switched to SLD for another 3 weeks + oral treatment as follows: G2+ no treatment (positive control), G3-G5 + 200, 400 and 800 mg/kg/day aqueous A. digitata fruit respectively, G6 + 10 mg/kg/day Simvastatin. G7 + HS/HFD + 400 mg/kg/day A. digitata fruit simultaneously and was terminated at W6. Our results showed that G2-G6 develops dyslipidemia, hyperglycaemia, weight gain, elevated hepatic biomarkers, elevated creatinine and urea plus pathological derangements in the heart, liver and kidney tissues compared to negative control at W6. 200 mg/kg/day A. digitata fruit significantly ameliorated the induced dyslipidemia (P ≤ 0.001), hyperglycaemia (P ≤ 0.001) with a significant reduction in the Atherogenic Index of Plasma (P ≤ 0.000) after 3 weeks treatment. The fruit normalized the elevated hepatic biomarkers as well as creatinine and urea. A dose dependent partial reduction in lesion intensity was observed in the hepatic tissue while the heart and kidney showed mostly reversed to normal histology. The inflammatory infiltration was eliminated. Relevant results were observed for the two higher doses. The simultaneous treatment showed significant lower levels in all biomarkers investigated compared to positive control which could be interpreted as protective activity. A reduction of 4-11% in whole body weight was achieved. CONCLUSION: MetS was successfully simulated with a HS/HFD formula in male Wistar rats. Treatment with aqueous A. digitata fruit showed anti-Metabolic Syndrome potential reflected by weight loss, anti-inflammatory, hypolipidemic, hypoglycaemic, renal, hepatic and cardio-protective activities.
代谢综合征是一种代谢紊乱的复杂病症,其特征是氧化应激,这会损害细胞功能并导致多个器官发生病变。我们研究了猴面包树果实(一种强大的抗氧化剂)在高糖/高脂肪饮食诱导的 Wistar 大鼠代谢综合征中的治疗和保护潜力。42 只雄性大鼠(140-200g)被随机分为 7 组。G1 组在整个 9 周内均给予标准实验室饮食(SLD)(阴性对照)。5 组给予高糖/高脂肪饮食 6 周,然后切换至 SLD 再给予 3 周口服治疗,如下所示:G2-未治疗(阳性对照),G3-G5 分别给予 200、400 和 800mg/kg/天的猴面包树果实水溶液,G6-给予 10mg/kg/天辛伐他汀。G7-给予 HS/HFD+400mg/kg/天的猴面包树果实,同时在 W6 时终止。我们的结果表明,与阴性对照相比,G2-G6 在 W6 时出现血脂异常、高血糖、体重增加、肝生物标志物升高、肌酐和尿素升高以及心脏、肝脏和肾脏组织的病理紊乱。200mg/kg/天的猴面包树果实可显著改善诱导的血脂异常(P≤0.001),高血糖(P≤0.001),同时降低血浆致动脉粥样硬化指数(P≤0.000),治疗 3 周后。该果实使升高的肝生物标志物以及肌酐和尿素正常化。在肝组织中观察到剂量依赖性的病变强度部分减轻,而心脏和肾脏组织主要恢复正常组织学。炎症浸润被消除。观察到两个较高剂量的相关结果。与阳性对照相比,同时治疗显示所有研究生物标志物的水平均显著降低,这可以解释为保护活性。体重减轻了 4-11%。结论:HS/HFD 配方成功地在雄性 Wistar 大鼠中模拟了代谢综合征。用猴面包树果实水溶液治疗表现出抗代谢综合征的潜力,表现为体重减轻、抗炎、降血脂、降血糖、肾、肝和心脏保护作用。
