Type 1 diabetes encompasses a spectrum of metabolic disorders marked by insulin deficiency, resulting in elevated blood glucose levels, commonly referred to as hyperglycemia. This persistent condition often precipitates lipid profile abnormalities, causing cholesterol alterations, low-and high-density lipoproteins, and triglycerides. The liver is particularly vulnerable to increased oxidative stress and inflammatory responses, which activate the transcription of pro-apoptotic genes and ultimately contribute to hepatocyte damage. This study analyzed the potential therapeutic role of raspberry ketone (RK), a natural antioxidant with antiapoptotic and anti-inflammatory properties, in male albino rats with induced type 2 diabetes. Fifty rats were equally divided into five groups: control, rats orally administered 200 mg /kg Body Weight (BW) RK for 5 days, diabetic rats intramuscularly injected once with 60 mg/kg BW streptozotocin, streptozotocin-induced diabetic rats orally administered 200 mg/kg BW RK for 5 days, and streptozotocin-induced diabetic rats orally administered 100 mg/kg metformin. Streptozotocin treatment significantly affected blood biochemical parameters, lipid profiles, oxidative stress markers, immunotoxicity biomarkers, and DNA damage biomarkers. Conversely, RK efficiently ameliorated the toxic effects of streptozotocin on the liver by reducing the pathological and biochemical changes associated with diabetes through its antioxidant and anti-inflammatory properties. Therefore, incorporating RK into the diet of diabetic patients can help prevent hepatocyte damage associated with diabetes. In conclusion, oral administration of RK exerts hepatoprotective effects by offering antioxidant, antiapoptotic, and anti-inflammatory properties against streptozotocin-induced type 1 diabetes in male rats.
1型糖尿病涵盖一系列以胰岛素缺乏为特征的代谢紊乱,导致血糖水平升高,通常称为高血糖症。这种持续性病症常引发脂质异常,导致胆固醇变化、低密度脂蛋白和高密度脂蛋白以及甘油三酯异常。肝脏特别容易受到氧化应激增加和炎症反应的影响,这些反应会激活促凋亡基因的转录并最终导致肝细胞损伤。本研究分析了具有抗凋亡和抗炎特性的天然抗氧化剂覆盆子酮(RK)对诱导型2型糖尿病雄性白化大鼠的潜在治疗作用。50只大鼠平均分为五组:对照组、口服200mg/kg体重(BW)RK持续5天的大鼠、肌肉注射一次60mg/kg BW链脲佐菌素的糖尿病大鼠、口服200mg/kg BW RK持续5天的链脲佐菌素诱导糖尿病大鼠以及口服100mg/kg二甲双胍的链脲佐菌素诱导糖尿病大鼠。链脲佐菌素治疗显著影响血液生化参数、脂质谱、氧化应激标志物、免疫毒性生物标志物和DNA损伤生物标志物。相反,RK通过其抗氧化和抗炎特性减轻与糖尿病相关的病理和生化变化,有效改善了链脲佐菌素对肝脏的毒性作用。因此,将RK纳入糖尿病患者的饮食中有助于预防与糖尿病相关的肝细胞损伤。总之,口服RK通过对链脲佐菌素诱导的雄性大鼠1型糖尿病提供抗氧化、抗凋亡和抗炎特性发挥肝保护作用。
