    摘要:

    目的 探讨两种小型猪作为代谢综合征模型动物的可行性。方法 选择巴马小型猪和西藏小型猪,测量体重、体尺以及与代谢综合征有关指标-血脂、血糖、自由基水平,在不同种和性别之间进行比较分析。结果 与西藏小型猪比较,巴马小型猪体重大,体长度短,颈围大,腹围大,肥胖指数高,而且差异在雌性巴马小型猪中更加显著。TC、HDL-C、LDL-C、TC水平在雌性小型猪高于雄性小型猪。GLU水平在巴马小型猪高于西藏小型猪,并与雌性西藏小型猪的差异显著,而FRA和HbAlc水平在西藏小型猪高于巴马小型猪,Insulin水平在雌性巴马小型猪和雄性西藏小型猪中分别高于雄性巴马小型猪和雌性西藏小型猪。MDA水平在雌性巴马小型猪中显著高于雄性巴马小型猪和西藏小型猪,SOD和GSH-Px水平在巴马小型猪中高于西藏小型猪。结论 通过体重、体尺、血脂、血糖和自由基水平等正常生理指标的分析,巴马小型猪倾向于肥胖;两种小型猪血脂雌性高于雄性;巴马小型猪空腹血糖高于西藏小型猪,但巴马小型猪的血糖控制能力优于西藏小型猪;巴马小型猪抗氧化能力优于西藏小型猪。总之,在代谢综合征相关研究中根据具体需求进行选择不同种、不同性别的小型猪并以具体造模实践来加以验证。

    Abstract:

    Objective To explore the possibility of two kind of minipigs as the animal model for metabolic syndrome. Methods Bama minipigs and Tibet minipigs were selected to measure their body weight, body size and metabolic syndrome-related parameters including blood lipid, blood sugar and free radical. Results Compared with Tibet minipigs, Bama minipigs was heavier in weight, shorter in length, larger in neck circumference and abdominal circumference, higher in obesity index, and what's more, the difference in female Bama minipigs was more significant. The levels of TC, LDL-C, HDL-C and TC were higher in female than in male. GLU levels in Bama minipigs was higher than that of Tibet minipigs, and with differences in female Tibet minipigs significantly, while the level of FRA and HbA1c in the Tibet minipig was higher than that of Bama minipigs, Insulin level in female Bama minipigs and male Tibet minipigs was respectively higher than the male Bama minipigs and female Tibet minipigs. MDA levels in female Bama minipigs was significantly higher than that of male Bama minipigs and Tibet minipigs, the level of SOD and GSH-Px in Bama minipigs was higher than that of Tibet minipigs. Conclusions Through the analysis of normal physiological parameters, such as body weight, body measurement, blood lipid, blood sugar and free radical, Bama minipigs tend to be obese; the level of blood fat of female is higher than that of male in two kind of minipigs; the level of blood sugar of Bama minipigs is higher than that of Tibet minipigs, but the ability of Bama minipigs to control blood sugar is better than Tibet minipigs; the ability of Bama minipigs to antioxide is better than Tibet minipigs. In short, according to the specific needs different kinds of minipigs are selected to use in the metabolic syndrome-related research and verified in actual modeling practices.
