Ｗｉｓｔａｒ大鼠２个年龄组，每个年龄段随机分为３组。实验１组给碘１．６７μｇ／ｋｇ体重，实验共进行３０天。实验结果：大鼠补碘后，体重为１２０～１５０ｇ的大鼠经３０天喂养后，脑内去甲肾上腺素含量高、低剂量组均与对照组有显著性差异（Ｐ＜０．００１，Ｐ＜０．００２）；体重为５０～７０ｇ的大鼠经３０天喂养后，高剂量组与对照组有显著性差异（Ｐ＜０．０５）。多巴胺含量，２个年龄段大鼠经３０天喂养后，均为高剂量组与对照组有显著性差异（Ｐ＜０．０５）。结论：健康发育的大鼠补碘一段时间后，可提高其大脑神经递质去甲肾上腺素和多巴胺的释放
Wistar rats 2 age groups, each age group were randomly divided into 3 groups. In the experimental group 1, iodine 1.67 μg / kg body weight was administered for 30 days. Experimental results: After iodine supplementation in rats, the rats with body weight of 120 ~ 150g fed 30 days, the content of norepinephrine in the brain was high and the low dose group was significantly different from the control group (P <0.001, P <0.002). After being fed for 30 days, the weight of rats in the range of 50 ~ 70g was significantly lower than that in the control group (P <0.05). Dopamine content, two age groups after feeding for 30 days, were high-dose group and the control group were significantly different (P <0.05). CONCLUSIONS: After a period of iodine supplementation in healthy rats, the release of norepinephrine and dopamine, a neurotransmitter in the brain, can be increased
