牛蛙和中华鳖甲状腺、肾上腺显微结构的比较研究

Comparative Research of Microstructure about Thyroid Gland and Adrenal Gland in Rana Catesbeiana and Trionyx Sinensis

将健康的活体牛蛙、中华鳖的肾上腺、甲状腺取出,用Bouin氏液固定,包埋,切片,H-E染色法染色。比较观察后发现:牛蛙的肾上腺由成堆的细胞小体和管状体构成,中华鳖则由皮质和髓质构成,两者有明显的区别。但甲状腺牛蛙和中华鳖都是由滤泡组成,滤泡周围由丰富的毛细血管和网状纤维构成,其间充满均质状的胶体物质。

Take out the thyroid gland, adrenal gland from healthy hving body in Rana catesbeiana and Trionyx sinensis, fix them with Bouin hquid, embred,shce and H-E dye. Observation showed that the adrenal gland of Rana catesbeiana comprised cytoidbody and siphonozooid,but the adrenal gland of Trionyx sinensis comprised pallium and medulla.They had obvious differences.However, the thyroid gland in Rana catesbeiana and Tffonyx sinensis consisted of follicle.The follicle was surrounded with capillary vessel and lattice fibers, and filled with homogeneous colloidal substance inside.
