Persistent hyperglycemia is known to cause enhanced generation of reactive oxygen species in diabetes. Several inflammatory cytokines are induced by oxidative stress, and their release also leads to increased oxidative stress; this makes oxidative stress one of the important factors in the development of chronic inflammation and other immune responses. These have been implicated in the development of diabetic complications such as nephropathy and cardiomyopathy. has been shown to possess antioxidant and anti-inflammatory potentials. The present study investigated the immunomodulatory potential and the antiapoptotic ability of to ameliorate heart toxicity and injury in type II diabetes. Two weeks of fructose (10%) administration followed by single intraperitoneal injection of streptozotocin (40 mg/kg) were used to induce type II diabetes in male Wistar rats. Leaf extract (aqueous) of (200 and 400 mg/kg) was administered orally for six weeks. Blood glucose concentrations and body weights before and after interventions were determined. Interleukin (IL)-1β, IL-6, IL-10, IL-18, monocyte chemoattractant protein 1 (MCP-1), and tumor necrosis factor alpha (TNFα) were measured in the heart homogenates. Catalase (CAT), superoxide dismutase (SOD), total protein, oxygen radical absorbance capacity (ORAC), ferric reducing antioxidant power (FRAP), thiobarbituric acid reactive substances (TBARS), and heart-type fatty acid-binding protein (H-FABP) levels were determined. Expressions of transcription factors (Nrf 2 and NFkB/p65) and apoptotic markers were also investigated in the heart. administration reduced pro-inflammatory cytokines, increased anti-inflammatory markers, and enhanced antioxidant defense in the heart of diabetic treated animals. is a new, promising therapeutic agent that can be explored for the treatment of pathological conditions associated with immune responses and will be a useful tool in the management of associated diabetic complications.
已知持续性高血糖会导致糖尿病中活性氧的生成增加。氧化应激会诱导多种炎性细胞因子,它们的释放也会导致氧化应激增加;这使得氧化应激成为慢性炎症和其他免疫反应发展的重要因素之一。这些因素与糖尿病并发症如肾病和心肌病的发生有关。已证明具有抗氧化和抗炎潜力。本研究调查了改善II型糖尿病心脏毒性和损伤的免疫调节潜力和抗凋亡能力。给雄性Wistar大鼠连续两周给予果糖(10%),然后单次腹腔注射链脲佐菌素(40mg/kg)以诱导II型糖尿病。口服(200和400mg/kg)叶提取物(水提取物)六周。测定干预前后的血糖浓度和体重。测定心脏匀浆中的白细胞介素(IL)-1β、IL-6、IL-10、IL-18、单核细胞趋化蛋白1(MCP-1)和肿瘤坏死因子α(TNFα)。测定过氧化氢酶(CAT)、超氧化物歧化酶(SOD)、总蛋白、氧自由基吸收能力(ORAC)、铁还原抗氧化能力(FRAP)、硫代巴比妥酸反应性物质(TBARS)和心脏型脂肪酸结合蛋白(H-FABP)水平。还研究了心脏中转录因子(Nrf 2和NFkB/p65)和凋亡标志物的表达。给药降低了糖尿病治疗动物心脏中的促炎细胞因子,增加了抗炎标志物,并增强了抗氧化防御。是一种新的、有前景的治疗剂,可用于探索治疗与免疫反应相关的病理状况,将成为管理相关糖尿病并发症的有用工具。
