The microvascularization of the thyroid gland in rats was studied in animals following ingestion of potassium bromide in various concentrations in drinking water (15, 50 or 100 mg/l) over a period of either 16 or 66 days. Accordingly, animals were divided into six study groups and one control group. Microvascularization was compared among the groups. The pattern of thyroidal follicle distribution within the blood vessels was evaluated by scanning electron microscopy. Animals that ingested potassium bromide presented an increased density and number of meshes in the capillary network of the follicle. The peripheral vessels showed flattening of the walls and in the central portion of the follicle, the distribution of the capillary network did not undergo any morphologic alteration.
研究了大鼠甲状腺的微血管形成情况，这些大鼠在16天或66天的时间里饮用含有不同浓度（15、50或100毫克/升）溴化钾的水。相应地，将动物分为六个研究组和一个对照组。比较了各组之间的微血管形成情况。通过扫描电子显微镜评估血管内甲状腺滤泡的分布模式。摄入溴化钾的动物滤泡毛细血管网中的网孔密度和数量增加。外周血管壁出现扁平，而在滤泡的中央部分，毛细血管网的分布未发生任何形态学改变。
