Acute pancreatitis (AP) is an inflammatory disease that causes severe tissue damage. Ghee butter from bovine colostrum (GBBC) is a clarified butter produced by heating milk fat to 40 °C and separating the precipitating protein. As colostrum mainly contains fatty acids (FAs), immunoglobulins, maternal immune cells, and cytokines, we hypothesized that it may exert anti-inflammatory effects. We investigated the effects of GBBC on experimental AP in mice. Two intraperitoneal () injections of L-arginine (8%) were given 1 h apart to generate the AP murine model. After 12 h from the first L-arginine injection, mice were divided into the following experimental groups: AP mice treated with GBBC (oral gavage () every 12 h) and non-treated AP mice ( vehicle every 12 h). Control animals received vehicle only. At 72 h, mice were euthanized. Histopathological examination along with myeloperoxidase (MPO) and amylase/lipase activity assays were performed. In a separate set of experiments, FFAR1 and FFAR4 antagonists were used to verify the involvement of respective receptors. Administration of GBBC decreased MPO activity in the pancreas and lungs along with the microscopical severity of AP in mice. Moreover, treatment with GBBC normalized pancreatic enzyme activity. FFAR1 and FFAR4 antagonists tended to reverse the anti-inflammatory effect of GBBC in mouse AP. Our results suggest that GBBC displays anti-inflammatory effects in the mouse model of AP, with the putative involvement of FFARs. This is the first study to show the anti-inflammatory potential of a nutritional supplement derived from GBBC.
急性胰腺炎(AP)是一种会导致严重组织损伤的炎症性疾病。牛初乳酥油(GBBC)是通过将乳脂肪加热至40°C并分离沉淀的蛋白质而制成的澄清黄油。由于初乳主要含有脂肪酸(FAs)、免疫球蛋白、母体免疫细胞和细胞因子,我们推测它可能具有抗炎作用。我们研究了GBBC对小鼠实验性AP的影响。间隔1小时腹腔注射两次8%的L-精氨酸以建立AP小鼠模型。在首次注射L-精氨酸12小时后,将小鼠分为以下实验组:用GBBC治疗的AP小鼠(每12小时灌胃一次)和未治疗的AP小鼠(每12小时给予赋形剂)。对照动物仅接受赋形剂。72小时后,对小鼠实施安乐死。进行了组织病理学检查以及髓过氧化物酶(MPO)和淀粉酶/脂肪酶活性测定。在另一组实验中,使用FFAR1和FFAR4拮抗剂来验证各自受体的参与情况。给予GBBC可降低小鼠胰腺和肺中的MPO活性以及AP的显微镜下严重程度。此外,用GBBC治疗可使胰腺酶活性恢复正常。FFAR1和FFAR4拮抗剂倾向于逆转GBBC在小鼠AP中的抗炎作用。我们的结果表明,GBBC在AP小鼠模型中显示出抗炎作用,可能涉及FFARs。这是第一项显示源自GBBC的营养补充剂具有抗炎潜力的研究。
