Serum levels of aldosterone, tri-iodo thyronine (T3) and thyroxine (T4) were measured in male and female rats aged 3 months, 12 months, and 18 months. Female rats were found to have higher aldosterone and T3 levels, and lower T4 level than the male. No age-related change was observed in serum aldosterone in either sex. In contrast, serum T4 were found to decrease with age in both sexes while serum T3 showed an age-associated diminution in the male only. Serum testosterone was also measured in the male rats and was found to decline with age.
对3个月、12个月和18个月大的雄性和雌性大鼠的血清醛固酮、三碘甲状腺原氨酸（T3）和甲状腺素（T4）水平进行了测量。发现雌性大鼠的醛固酮和T3水平高于雄性，而T4水平低于雄性。在任何性别中，均未观察到血清醛固酮与年龄相关的变化。相比之下，发现两性的血清T4均随年龄下降，而血清T3仅在雄性中显示出与年龄相关的降低。还对雄性大鼠的血清睾酮进行了测量，发现其随年龄下降。
