The present study investigated the effects of murici and tapereba on improving hepatic and inflammatory biomarkers in high-fat-diet rats. Female Wistar rats were divided into five groups ( = 10/group): control (CON), high-fat diet (HF), murici drink + high-fat diet (Mu-HF), tapereba drink + high-fat diet (Tap-HF), and murici and tapereba blend drink + high-fat diet (MT-HF). Drinks were offered daily for 60 days, following which body and liver weights, hepatosomatic indexes, serum parameters, inflammatory profile, and antioxidant activity (DPPH and ORAC) were analyzed. The cell death of hepatic cells was evaluated using flow cytometry. It was observed that weight gain was similar among the groups, while glycemia was lower in the MT-HF group. A high-fat diet increased the concentration of cholesterol total, ALT, IL-1β (in plasma and liver), and TNF-α (in the liver), and this was reduced by treatment with the fruit-based beverages. The other evaluated parameters showed no statistically significant difference. Compared to the CON and HF groups, the groups that received the drinks had higher cellular antioxidant activity and reduced oxidative stress, lipid oxidation, and development of pro-inflammatory cytokines, such as IL-1β. A high-fat diet induced higher cell death in hepatic tissue, which was prevented by the murici, tapereba, and the fruit-blend drinks. The consumption of murici, tapereba, and fruit-blend-based beverages showed beneficial effects on liver metabolism; therefore, they may serve as a nutritional approach for preventing and treating non-alcoholic liver disease.
本研究调查了murici和tapereba对改善高脂饮食大鼠肝脏和炎症生物标志物的影响。将雌性Wistar大鼠分为五组(每组n = 10):对照组(CON)、高脂饮食组(HF)、murici饮料+高脂饮食组(Mu-HF)、tapereba饮料+高脂饮食组(Tap-HF)以及murici和tapereba混合饮料+高脂饮食组(MT-HF)。每天提供饮料,持续60天,之后分析体重、肝脏重量、肝体指数、血清参数、炎症指标以及抗氧化活性(DPPH和ORAC)。使用流式细胞术评估肝细胞的细胞死亡情况。观察到各组间体重增加相似,而MT-HF组的血糖较低。高脂饮食增加了总胆固醇、ALT、IL-1β(血浆和肝脏中)以及TNF-α(肝脏中)的浓度,而用基于水果的饮料治疗可使其降低。其他评估参数无统计学显著差异。与CON组和HF组相比,接受饮料的组具有更高的细胞抗氧化活性,且氧化应激、脂质氧化以及促炎细胞因子如IL-1β的产生减少。高脂饮食诱导肝脏组织中细胞死亡增加,而murici、tapereba以及混合水果饮料可预防这种情况。食用murici、tapereba以及基于混合水果的饮料对肝脏代谢显示出有益作用;因此,它们可作为预防和治疗非酒精性肝病的一种营养方法。
