[摘要]目的 探讨林蛙油对小鼠的免疫调节作用。方法 将240只小白鼠随机分为6个免疫群组,每个免疫群组40只。每个免疫群组根据人口服推荐剂量(5、10、20倍)设林蛙油低、中、高剂量组[分别为334、667、1334 mg/(kg·BW)]和阴性对照组,每组10只动物。按0.2 ml/(10 g·BW)的体积经口给予小鼠灌胃,每天灌胃1次,连续灌胃30 d后,进行各项免疫指标的测定。结果 林蛙油剂量组与阴性对照组比较能促进小鼠脾淋巴细胞增殖、转化作用(P<0.05),促进小鼠的迟发型变态反应(P<0.05),促进小鼠的抗体生成细胞增加及提高小鼠的血清溶血素水平(P<0.05),增强小鼠的单核-巨噬细胞吞噬能力(P<0.05),提高小鼠的NK细胞活性(P<0.05)。结论 林蛙油具有增强免疫力的功能。

[Abstract]Objective To explore the effect of Oviductus ranae on the function of immunoregulation.Methods 240 mice were randomly divided into 6 groups of immune group,each group had 40 mice,each immune group was divided into low,medium and high dose group [334,667,1344 mg/(kg·BW)] and negative control group according to recommended oral dose (5,10,20 times) of Oviductus ranae 10 rats in each group.The mice were given intragastric administration according to volume of 0.2 ml/(10 g·BW),intragastric administration was given 1 time a day,and the immune indexes were measured after continuous intragastric administration of 30 d.Results The results of Oviductus ranae dose groups in comparison with the negative control group showed that proliferation and transformation of splenic lymphocyte were enhanced (P<0.05);promoting mice late hairstyle allergy (P<0.05);quantity of mice antibody-producing cell and sheep erythrocyte antibody levels in serum were raised(P<0.05);mononuclear celiac macrophage phagocytic activity were increased (P<0.05);the activity of NK cells in mice was inhanced(P<0.05).Conclusion It is suggested that Oviductus ranae can enhance immune function.

林蛙油(oviductus ranae)又叫雪蛤油、蛤蟆油,特指中国林蛙长白山亚种雌哈蟆的输卵管。林蛙油具有生津润肺、益胃健脾、益精补肾等功效,其营养保健价值极高。现代医学研究表明,林蛙油具有增强免疫力、抗衰老、抗氧化、抗疲劳、调节血脂、抗焦虑等多种作用[1-5]。目前国内报道中关于林蛙油免疫调节作用的文献不少[6-8],但均局限于细胞免疫功能检测,对体液免疫功能检测报道不足。本实验通过细胞免疫和体液免疫等方面检测的全面研究,为评价林蛙油对小鼠的免疫调节作用提供实验依据。
