Results Iodine-excess groups show diffused colloid goiter; 结果碘过量组小鼠出现了弥漫胶质性甲状腺肿;
Results In HO and HI, colloid goiter was encountered and the absolute and relative weight of thyroid increased. 结果HO和HI组小鼠甲状腺出现胶质样肿大、绝对质量和相对质量增加。
The thyroid in three experimental groups was typical colloid goiter. 实验各组甲状腺呈典型的胶质性甲状腺肿。
The thyroid morphology is colloid goiter, and with iodine dose increasing, the follicular epithelial cells gradually become thallus, the nuclear become shuttle, the cavity of follicle gradually spread, colloid content gradually increasing. 甲状腺组织为胶质性甲状腺肿,且随碘剂量的增加,甲状腺滤泡上皮细胞逐渐变为扁平,核呈梭形,滤泡腔逐渐扩大,胶质逐渐增多。
According to the results of this study, excess tyrosine have the protective function to colloid goiter caused by excess iodine. 4根据本次研究结果,高酪氨酸对高碘所致的甲状腺肿有保护作用。
Excess iodine could result in colloid goiter in mice when tyrosine was at adequate or high level. The goiter degree reduced obviously when tyrosine was at high level. 2. 结论:1在适酪氨酸或高酪氨酸的情况下,高碘均可引起小鼠胶质性甲状腺肿,但在高酪氨酸的情况下病情明显减轻。
