[Morphological peculiarities of human anal glands during postnatal ontogenesis].
Macro-microscopical and histological methods were used to study the age-related peculiarities of human anal glands in 267 practically healthy subjects of both sexes of various ages (from newborns to 102 years). Topography of anal glands was described, their numbers and dimensional parameters were determined in the subjects of different age. Maximal total number of these glands, maximal length and width of their initial region, as well as maximal number of initial portions within it, were found at the age of 22-35 years. Subsequently, as the age increased, these parameters tended to decrease. Connective tissue fiber content in the glands was found to increase during postnatal ontogenesis. Along the course of common excurrent duct in submucosa and in mucosa, some dilated regions were found, especially in aged and senile persons.
