The aim of this study was to evaluate the effects and mechanisms of Setarud (IMOD™) as a multi-herbal medicinal formula on a mouse model of type 1 diabetes. METERIAL AND METHODS: Autoimmune diabetes was induced by multiple low-dose intraperitoneal injection of 40 mg/kg of streptozotocin (STZ) for five consecutive days. IMOD™ was administered at an effective dose of 20 mg/kg/day for 21 days. After 21 days of treatment, the pancreases of the animals were separated and homogenized. In the pancreas tissue, the level of lipid peroxidation as thiobarbituric acid reactive substances (TBARS), total antioxidant power as ferric reducing ability of pancreas (FRAP), myeloperoxidase (MPO), and the concentrations of interleukin-1 (IL-1β) and tumour necrosis factor-α (TNF-α) were evaluated. Glucose changes were tested in the blood. Microscopic changes in the pancreas were followed by histological examinations.
No significant difference was found between IMOD™ and diabetic control groups in blood glucose pattern. STZ-exposed mice showed a significant increase in pancreatic TBARS, MPO, IL-1β, and TNF-α levels, along with a significant decrease in FRAP value. Co-administration of IMOD™ significantly improved all the mentioned parameters disrupted by STZ administration except for blood glucose and histological changes.
IMOD™ could ameliorate oxidative and immunological distresses of type-1 immunogenic diabetes but could not normalize blood glucose. Further studies are recommended to clarify the effects of IMOD™ on immunological factors to address whether this new agent could be applied in diabetes prevention or therapy.
本研究旨在评估 Setarud(IMOD™)作为一种多草药配方对 1 型糖尿病小鼠模型的作用及其机制。
通过连续 5 天腹腔内注射 40mg/kg 链脲佐菌素(STZ)诱导自身免疫性糖尿病。IMOD™以 20mg/kg/天的有效剂量给药 21 天。治疗 21 天后,分离并匀浆动物的胰腺。在胰腺组织中,评估脂质过氧化水平(作为硫代巴比妥酸反应物质(TBARS))、总抗氧化能力(作为胰腺铁还原能力(FRAP))、髓过氧化物酶(MPO)以及白细胞介素-1(IL-1β)和肿瘤坏死因子-α(TNF-α)的浓度。检测血液中的葡萄糖变化。通过组织学检查观察胰腺的微观变化。
在血糖模式方面,IMOD™与糖尿病对照组之间没有发现显著差异。暴露于 STZ 的小鼠胰腺 TBARS、MPO、IL-1β 和 TNF-α 水平显著升高,而 FRAP 值显著降低。与 STZ 给药组相比,IMOD™ 联合给药显著改善了所有上述参数,除了血糖和组织学变化。
IMOD™ 可以改善 1 型免疫性糖尿病的氧化和免疫应激,但不能使血糖正常化。建议进一步研究以阐明 IMOD™ 对免疫因素的影响,以确定该新药物是否可用于糖尿病的预防或治疗。
