Hyperglycemia mediated oxidative stress plays a key role in the pathogenesis of diabetic complications like nephropathy. In the present study, we evaluated the effect of ethanolic extract of Ensete superbum seeds (ESSE) on renal dysfunction and oxidative stress in streptozotocin-induced diabetic rats.
Glucose, HbA1c, total protein, albumin, renal function markers (urea, uric acid and creatinine), and lipid peroxidation levels were evaluated. Renal enzymatic and non-enzymatic antioxidants were examined along with renal histopathological study.
ESSE (400 mg/kg BW t) administration reduced glucose and HbA1c, and improved serum total protein and albumin in diabetic rats. ESSE in diabetic rats recorded decrement in renal function markers and renal lipid peroxidation products along with significant increment in enzymatic and non-enzymatic antioxidants. Renal morphological abnormalities of diabetic rats were markedly ameliorated by E. superbum.
These results suggest that the antioxidant effect of E. superbum could ameliorate oxidative stress and delay/prevent the progress of diabetic nephropathy in diabetes mellitus.
高血糖介导的氧化应激在糖尿病肾病等糖尿病并发症的发病机制中起关键作用。在本研究中,我们评估了埃塞俄比亚香蕉种子乙醇提取物(ESSE)对链脲佐菌素诱导的糖尿病大鼠肾功能障碍和氧化应激的影响。
评估血糖、糖化血红蛋白、总蛋白、白蛋白、肾功能指标(尿素、尿酸和肌酐)以及脂质过氧化水平。检测肾脏酶促和非酶促抗氧化剂,并进行肾脏组织病理学研究。
给予ESSE(400mg/kg体重)可降低糖尿病大鼠的血糖和糖化血红蛋白,并改善血清总蛋白和白蛋白水平。糖尿病大鼠服用ESSE后,肾功能指标和肾脏脂质过氧化产物减少,同时酶促和非酶促抗氧化剂显著增加。埃塞俄比亚香蕉显著改善了糖尿病大鼠的肾脏形态异常。
这些结果表明,埃塞俄比亚香蕉的抗氧化作用可改善氧化应激,延缓/预防糖尿病患者糖尿病肾病的进展。
