Abstract

Background: Kidney disease is a leading cause of death in the United States and the world. Proteinuria signifies kidney damage and can exacerbate kidney disease. It has become an important indicator of kidney disease; reducing proteinuria results in renoprotective effects and slows renal disease. Existing treatments do not work for every patient. Aim of Study: Amaranth is a tropical plant that was regularly consumed in the ancient Central American diet. It has a plethora of health effects and is a strong functional food candidate. This study examines whether a regular oral dose of amaranth oil decreased proteinuria concentration in murine subjects.  Methods: Mice in the experimental group (n = 3) were given 4μl of amaranth oil per gram of mouse weight for 5 days a week over 84 days. Control mice (n = 2) were sham treated on the same schedule with no oil. Urine protein concentration was determined by Bradford assay, measuring absorbance at 595nm, then comparing with a BSA standard curve.  Results: The experimental group showed decreased proteinuria levels throughout the entire 84 days of study.Conclusion: Results show amaranth oil may help decrease proteinuria levels in lupus prone murine subjects. Given the small sample size, the data are preliminary. More research is needed to validate the results, and determine the optimal dose and treatment schedule. Key words: proteinuria, amaranth oil, renoprotective, kidney disease, renal disease, lupus, functional food

苋菜油对狼疮易感小鼠蛋白尿的影响
背景:肾脏疾病是美国和世界上导致死亡的主要原因。蛋白尿表明肾脏受损,可加重肾脏疾病。它已成为肾脏疾病的重要指标;减少蛋白尿可以起到保护肾脏的作用,减缓肾脏疾病。现有的治疗方法并不是对每个病人都有效。研究目的:苋菜是一种热带植物,在古代中美洲饮食中经常食用。它对健康有很多影响,是一种强有力的功能性食品。本研究考察了定期口服苋菜油是否能降低小鼠尿蛋白浓度。方法:实验组小鼠(n = 3)每克小鼠体重给予苋菜油4μl,每周5天,连续给予84 d。对照小鼠(n = 2)按相同的治疗方案进行假治疗,不加油。采用Bradford法测定尿蛋白浓度,在595nm处测量吸光度,然后与BSA标准曲线进行比较。结果:在整个84天的研究中,实验组的蛋白尿水平下降。结论:苋菜油可降低狼疮易感小鼠的蛋白尿水平。由于样本量小,这些数据是初步的。需要更多的研究来验证结果,并确定最佳剂量和治疗计划。关键词:蛋白尿,苋菜油,肾保护,肾病,肾病,狼疮,功能食品
