The work is based on a morphological study of ampoules of the fallopian tubes of 130 young and senile women who gave birth. Macrometric, histological, immunohistochemical and micrometric methods of investigation were applied. The regularities of age-related morphological variability of the fallopian tube ampoule are revealed, which are manifested in a decrease in the parameters of their length, as well as external diameters in the middle of the ampoule and at the places of transition of the isthmus into the ampoule and ampoule into the funnel from young age to old age. Histoarchitectonics of ampoules of the fallopian tubes in women in old age is characterized by flattening of the epithelium of the mucous membrane, which forms an abundance of nearby thickened folds that form an uneven narrowing of the lumen of the ampoule. The thinning of the muscle membrane is determined with the growth of connective tissue instead of it and the accumulation of adipocytes in the subserose base. In old age, there is a more pronounced expression of vimentin, which can be traced not only in the endothelium and subendothelial layer of blood vessels, including capillaries, but also in individual fibroblasts. It was found that the features of the micrometric characteristics of the fallopian tube ampoules consist in a decrease in the inner perimeter of the epithelial lining and the lumen area, along with an increase in the area of their wall at the median cross-section in old age compared with young age. |
