Nutritional deficiencies are one of the main triggers for the development of gastrointestinal diseases, such as ulcerative colitis (UC). Therefore, the objective of the present work consisted of determining the nutrients present in the bone broth (BB) and evaluating their anti-inflammatory properties in a murine model of UC, induced by intrarectal administration of 2, 4, 6-trinitrobenzene sulfonic acid (TNBS), and acetic acid (AcOH). The BB was prepared from the femur of bovine cattle and cooked in distilled water for 8 h at 100 ± 2 °C. The BB was administered ad libitum to BALB/c mice for 10 days before the induction of UC. Colon samples were collected for histological analysis and determination of cytokine expression levels by qPCR. It was found that amino acids (AA) are the main nutritional contribution of BB, 54.56% of these correspond to essential AA. The prophylactic administration of BB in the murine model of UC reduced histological damage, decreased the expression of (61.12%), (94.70%), and (68.88%), and increased the expression of (177.06%), (541.36%), and (531.97%). This study shows that BB has anti-inflammatory properties, and its consumption can decrease the symptoms of UC.
营养缺乏是胃肠道疾病(如溃疡性结肠炎,UC)发展的主要诱因之一。因此,本研究的目的是确定牛骨汤(BB)中的营养素,并在 UC 的鼠模型中评估其抗炎特性,UC 通过直肠内给予 2,4,6-三硝基苯磺酸(TNBS)和乙酸(AcOH)来诱导。BB 是由牛的股骨在 100 ± 2°C 的蒸馏水中熬制 8 小时制备而成。在诱导 UC 之前,BB 被自由给予 BALB/c 小鼠 10 天。收集结肠样本进行组织学分析和 qPCR 测定细胞因子表达水平。结果发现,氨基酸(AA)是 BB 的主要营养贡献,其中 54.56%为必需氨基酸。在 UC 的鼠模型中预防性给予 BB 可减轻组织损伤,降低 (61.12%)、 (94.70%)和 (68.88%)的表达,并增加 (177.06%)、 (541.36%)和 (531.97%)的表达。本研究表明,BB 具有抗炎特性,其摄入可减轻 UC 的症状。
