在雌雄小白鼠对于碳粒清除能力的比较实验中,虽未发现明显区别,但动情前期小白鼠RES 吞噬活性比动情间期明显增加,可知雌性动物在性周期的某一阶段,其 RES 吞噬活性可能不同于雄性。小白鼠 RES 的吞噬活性随季节而变化,夏季活性较冬季增加约二倍。除气温而外,可能还有其他因素参与这种差异的形成。 In the comparative experiment of the carbon particle scavenging capacity of male and female mice, though no significant difference was found, the espole activity of RES in the prepubescent mice was significantly higher than that of the estrus. It is known that the RES phagocytic activity of the female animal at a certain stage of the sexual cycle. May be different from males. The phagocytic activity of mouse RES varied with the seasons, and the summer activity increased about two times compared with winter. In addition to temperature, there may be other factors involved in the formation of this difference.
