摘要: 以小鼠腹腔巨噬细胞为研究对象,探讨牛羊胆汁提取物甘氨胆酸(glycocholic acid,GCA)的抗氧化作用。将GCA分为1×10-3、1×10-4、1×10-5、1×10-6、1×10-7 μg/mL 5个质量浓度,与小鼠腹腔巨噬细胞共同孵育24 h后,按照试剂盒说明书提供的方法测定小鼠腹腔巨噬细胞中抗氧化酶谷胱甘肽过氧化物酶(GSH-Px)、超氧化物歧化酶(SOD)活性以及丙二醛(MDA)含量。结果表明,GCA能降低小鼠腹腔巨噬细胞中MDA的含量,同时提高小鼠腹腔巨噬细胞GSH-Px、SOD的活性,从而调节小鼠腹腔巨噬细胞的抗氧化应激水平。该试验结果提示甘氨胆酸具有改善抗氧化应激反应的能力。

Abstract: This study aimed to assess the antioxidative activity of glycocholic acid (GCA), one of the extracts from bile of cattle and sheep, on mouse peritoneal macrophages. A total of 5 experimental groups with mass concentrations of 1×10-3, 1×10-4, 1×10-5, 1×10-6 and 1×10-7 μg/mL of GCA were included. The mouse peritoneal macrophages were incubated with different concentrations of GCA for 24 hours, and the activities of glutathione peroxidase (GSH-Px)and superoxide dismutase (SOD), as well as the level of malondialdehyde (MDA), were determined according to the methods provided in the kit instructions. The results demonstrated that GCA reduced the level of MDA and elevated the activities of GSH-Px and SOD in mouse peritoneal macrophages, indicating its effective role in regulating the level of antioxidative stress in mouse peritoneal macrophages. In conclusion, GCA has the capacity to improve the antioxidative stress response.

Key words: glycocholic acid, mouse peritoneal macrophages, glutathione peroxidase, superoxide dismutase, malondialdehyde
