[Morphological characteristics of the intramural neural apparatus of the mesentery in neoplasms of the small and large intestines].

The author has studied the nervous elements of the mesentery in various tumors of the large and small intestine. Different structural alterations were found in all the components of the mesentery intramural nervous apparatus: nervous cells, the intracellular plexus, nervous fibres and receptor-structures in all kinds of neoplasms. Various impregnation technics, the Nissle method and routine coloring technics were employed. The variety in pattern of the revealed morphological alterations of the nervous elements and the rate of their involvement are found to be directly dependent on the tumor stage and form, duration of the lesion and the body responsiveness.
