| 摘 要： | 以野生长爪沙鼠为对象,通过外源注射植物血凝素(Phytohemagglutinin,PHA)和磷酸盐缓冲液,分别测定了夏季和冬季沙鼠注射前、注射24 h 和48 h 后体重和静止代谢率(Resting metabolic rate,RMR)的变化,以及48 h 后沙鼠足增重量和白细胞总数(White blood cell counts,WBCs)的变化,以检测沙鼠的免疫功能和能量代价的性别和季节差异。结果显示:1)注射PHA 能显著增加沙鼠足重和白细胞的总数,夏季白细胞的总数高
于冬季;2)冬季沙鼠体重高于夏季,雄鼠大于雌鼠,但PHA 处理对注射前后沙鼠的体重无影响;3)冬季RMR高于夏季,雄鼠大于雌鼠,但PHA 处理对沙鼠的RMR 无影响,PHA 处理对注射前后沙鼠的RMR 也无影响。这些结果表明,长爪沙鼠对PHA 的反应具有季节差异,但无性别差异,也没有发现明显的能量学代价,这可能与野外环境条件的大幅度波动(如环境温度和食物条件等)和沙鼠的繁殖状态有关。

| Abstract: | To evaluate the season and gender differences,as well as the cost of mounting phytohemagglutinin(PHA) challenged immune response,we measured the variations of body mass and resting metabolic rate(RMR) before and after 24 h and 48 h by injections of PHA and PBS in male and female Mongolian gerbils in different seasons,as well as the changes of increased foot mass and the total number of white blood cell counts(WBCs) at the end of the experiment.The results showed that 1) Increased foot mass(%) was significan... |
