Abstract

influences on the organs and systems of the body, as well as on the functioning and processes of adaptation of the body to environmental factors. Conducting experimental research on the reconstruction of the thyroid gland in various pathological conditions requires a deeper study of the features of the structural organization of the specified organ in experimental animals. The use of anatomical, morphometric and histological research methods made it possible to find out the peculiarity of its macrostructure in white rats, in particular, the absence of a pyramidal lobe, the presence of an inconspicuous glandular isthmus, the mass of the thyroid gland of a white rat, which was 0.035±0.05 mg, the dimensions of the gland, in particular its length was 6.55±0.05 mm, width – 3.75±0.02 mm, thickness – 2.65±0.002 mm, tight fit of the thyroid gland capsule to its parenchyma, the difference in the thickness of the interlobular septa of the gland in its central and peripheral parts glands (thinner on the periphery), changes in the shape of gland cells depending on their functional state, placement of C cells singly between the basal membrane and the basal pole of thyrocytes (parafollicular arrange - ment) and the surrounding of these cells with a dense network of capillaries, which, in turn, is also a related feature of the location of human C cells, various levels of metabolic processes in the cellular elements of the thyroid gland of laboratory rats. The obtained data will make it possible to create a base based on which it is possible to establish reactive changes in the thyroid gland and further use the data in modelling the effects of various factors for the pre - vention and treatment of human thyroid pathology.
甲状腺的比较形态学
对身体器官和系统的影响,以及对身体对环境因素的功能和适应过程的影响。对各种病理状态下甲状腺的重建进行实验研究,需要对实验动物中指定器官的结构组织特征进行更深入的研究。利用解剖学、形态计量学和组织学的研究方法,发现了白鼠甲状腺宏观结构的特点,特别是没有锥体叶,有一个不明显的腺峡,白鼠甲状腺的质量为0.035±0.05 mg,腺体的尺寸,特别是其长度为6.55±0.05 mm,宽度为- 3.75±0.02 mm,厚度为- 2.65±0.002 mm,紧密配合的甲状腺囊薄壁组织,不同厚度的小叶间隔的中央和周边地区腺腺(薄外围),改变形状的腺体细胞根据其功能状态,单独放置C细胞基底膜和基底之间的极此外parafollicular安排,和我们周围的这些细胞密集的毛细血管网络,,,也是人类C细胞所在位置的一个相关特征,实验大鼠甲状腺细胞成分的各种水平的代谢过程。获得的数据将有可能创建一个基础,在此基础上可以建立甲状腺的反应性变化,并进一步使用这些数据对预防和治疗人类甲状腺病理的各种因素的影响进行建模。
