Abstract

Moringa oleifera (MO) has been recognized for its numerous beneficial properties. This study aimed to evaluate the potential antihypertensive effects of MO seeds in rats subjected to Nω-nitro-L-arginine methyl ester (L-NAME) exposure. Fifty male Wistar rats were randomly divided into five groups of 10 rats each for the experiment. Group A served as the control, received normal saline only, Group B received L-NAME (40 mg/kg) only, Group C received L-NAME (40 mg/kg) + 10% MO feed, Group D received L-NAME (40 mg/kg) + 20% MO feed, and Group E received L-NAME (40 mg/kg) + Lisinopril (10 mg/kg). Treatment was daily and covered a period of 5 weeks. Blood pressure and electrocardiographic measurements were obtained using a non-invasive tail cuff blood pressure device and a 6/7 lead computer ECG equipment, respectively. Heart and kidney tissues were analyzed for oxidative stress parameters, and immunohistochemistry and histopathology of the heart and kidney were conducted using standard methods. L-NAME treatment led to a significant increase in diastolic and systolic values compared to the control group. Serum nitric oxide concentration significantly decreased in rats that received L-NAME alone, while co-treatment with MO and Lisinopril showed a significant increase in nitric oxide levels. Co-treatment with MO and Lisinopril significantly reduced malondialdehyde (MDA) concentrations in the cardiac and renal tissues, whereas L-NAME alone caused a significant increase in MDA concentration. The expressions of cardiac and renal caspase-3 significantly increased in L-NAME alone treated rats, while co-treatments with MO and Lisinopril significantly reduced the expressions of caspase-3. In conclusion, co-treatment with MO effectively reduced arterial pressure and indices of hypertension in rats, mitigated the oxidative stress and apoptosis induced by L-NAME. Therefore, the inclusion of MO seeds in hypertension management may serve as an effective remedy. Keywords: Moringa oliefera, L-NAME, Hypertension, Oxidative Stress, Nitric oxide.

辣木饲料包合物对ω-硝基精氨酸甲酯(L-NAME)致小鼠高血压模型的影响。
辣木(MO)因其许多有益的特性而被公认。本研究旨在评价MO种子对ω-硝基- l -精氨酸甲酯(L-NAME)暴露大鼠的潜在降压作用。50只雄性Wistar大鼠随机分为5组,每组10只。A组作为对照组,仅给予生理盐水,B组给予L-NAME (40 mg/kg), C组给予L-NAME (40 mg/kg) + 10% MO饲料,D组给予L-NAME (40 mg/kg) + 20% MO饲料,E组给予L-NAME (40 mg/kg) +赖诺普利(10 mg/kg)。治疗每天进行,为期5周。分别采用无创尾袖血压仪和6/7导联计算机心电图仪测量血压和心电图。分析心脏和肾脏组织的氧化应激参数,并采用标准方法进行心脏和肾脏的免疫组织化学和组织病理学检查。与对照组相比,L-NAME治疗导致舒张和收缩值显著增加。单独使用L-NAME的大鼠血清一氧化氮浓度显著降低,而与MO和赖诺普利合用的大鼠血清一氧化氮水平显著升高。MO和赖诺普利联合治疗可显著降低心脏和肾脏组织中的丙二醛(MDA)浓度,而L-NAME单独治疗可显著增加MDA浓度。L-NAME单独处理大鼠心脏和肾脏caspase-3的表达显著升高,而MO和赖诺普利联合处理则显著降低caspase-3的表达。综上所述,MO可有效降低大鼠动脉压和高血压指标,减轻L-NAME诱导的氧化应激和细胞凋亡。因此,将MO种子纳入高血压管理可能是一种有效的补救措施。关键词:辣木,L-NAME,高血压,氧化应激,一氧化氮
