This study investigated the effects of Raffia palm wine (RPW) on redox imbalance, glycolytic and cholinergic enzymes, and ATPase activities in hyperglycemia-induced oxidative testicular injury. Type 2 diabetes (T2D) was induced in male albino rats (Sprague-Dawley) by first administering 10% fructose solution for 14 days, before injecting with an intraperitoneal injection (40 mg/kg body weight) of streptozotocin. Raffia palm wine was administered to two diabetic groups at 150 and 300 mg/kg body weight (bw), when untreated diabetic group was used as a negative control, and metformin-fed group was served as a positive control. The rats were sacrificed after 5 weeks of treatment, and testes were harvested. Treatment with RPW led to lower levels of nitric oxide, malondialdehyde and myeloperoxidase activity, with concomitant elevation of reduced glutathione level, superoxide dismutase, catalase and ATPase activities. Raffia palm wine also inhibited glycogen phosphorylase, glucose-6-phosphatase, fructose-1,6-bisphosphatase, and acetylcholinesterase, while restoring the altered testicular morphology to near-normal. The results of this study suggest the therapeutic potentials of RPW against the effects of T2D on testicular functions and morphology. PRACTICAL APPLICATIONS: Diabetes mellitus is one of the fastest growing global epidemy, with most developing countries being at the receiving end owing to the cost of treatment. Testicular damage has been recognized as one of the complications of diabetes, and if left untreated will lead to erectile dysfunction followed by infertility. Raffia palm wine is among the common natural beverage in West Africa, which is utilized for both social and medicinal purposes. In this study, for the first time we showed its ability to protect diabetes-induced testicular injury in type 2 diabetic rats. This may be of great benefit in managing diabetes associated erectly dysfunction and male infertility, as Raffia palm wine is readily available in all seasons. This study will also improve the medicinal use of this wine, which may also indirectly improve its commercial benefit.
本研究调查了酒椰棕榈酒(RPW)对高血糖诱导的睾丸氧化损伤中氧化还原失衡、糖酵解和胆碱能酶以及ATP酶活性的影响。通过先给雄性白化大鼠(斯普拉格-道利大鼠)喂食10%果糖溶液14天,然后腹腔注射链脲佐菌素(40毫克/千克体重)来诱导2型糖尿病(T2D)。将酒椰棕榈酒以150和300毫克/千克体重(bw)的剂量给予两个糖尿病组,未治疗的糖尿病组作为阴性对照,二甲双胍喂养组作为阳性对照。治疗5周后处死大鼠并摘取睾丸。用RPW治疗导致一氧化氮、丙二醛水平和髓过氧化物酶活性降低,同时还原型谷胱甘肽水平、超氧化物歧化酶、过氧化氢酶和ATP酶活性升高。酒椰棕榈酒还抑制糖原磷酸化酶、葡萄糖-6-磷酸酶、果糖-1,6-二磷酸酶和乙酰胆碱酯酶,同时使改变的睾丸形态恢复到接近正常。本研究结果表明RPW对T2D对睾丸功能和形态的影响具有治疗潜力。实际应用:糖尿病是全球增长最快的流行病之一,大多数发展中国家因治疗费用而承受后果。睾丸损伤已被确认为糖尿病的并发症之一,若不治疗将导致勃起功能障碍继而不育。酒椰棕榈酒是西非常见的天然饮品,兼具社交和药用价值。在本研究中,我们首次表明其对2型糖尿病大鼠糖尿病诱导的睾丸损伤具有保护作用。这对于管理与糖尿病相关的勃起功能障碍和男性不育可能具有极大益处,因为酒椰棕榈酒全年都很容易获得。本研究还将改善这种酒的药用价值,这也可能间接提高其商业效益。
