摘要:

根据我国免疫调节功能食品的评价方法,对乳铁素的免疫调节作用进行评价。在实验中,采用Balb/c 小鼠建立免疫低下模型,以不同剂量(400、40、4μg/ml)乳铁素对小鼠进行灌胃实验后。分别进行免疫脏器质量、细胞免疫功能、体液免疫功能、单核- 巨嗜细胞功能等指标检测。结果表明,在灌胃剂量为40μg/ml 时,结果均为阳性,判定乳铁素具有增强免疫力,但与剂量有关。

Abstract:

To understand the immunoregulatory function of lactoferricin, its effects on spleen index, thymus index, cellular immune response, humoral immune function and phagocytic function of mononuclear macrophage in mice with low immunity were investigated. In the present study, animal model with low immunity was established by administering Balb/c mice with cyclophosphamide (CY) by intraperitoneal injection and the mice were administered by gavage with different doses of lactoferrcin (400, 40, and 4 μg/ml). Our study demonstrates that the administration dose of lactoferricin of 40 μg/ml has positive effects on all of the aforementioned indexes, suggesting that lactoferricin is able to enhance the immunoregulatory function in a dosedependent manner.

Key words: lactoferricin, immunoregulatory function, intragastric administration
