[Effect of experimental resection of the pancreas on the structure of lymph nodes at the root of the small intestine mesentery].

Resection of 2/3 mass of the pancreas preserving the ducts of the central portion is accompanied in dogs by certain changes in lymph nodes of the small intestine radix mesenterii. The operative trauma is followed by size decrease of the lymph nodes owing to degeneration and migration of lymphocytes. Absorbtion of decay products from the operative wound results in lymphocytic blasttransformation and proliferation. By the end of the first and beginning of the second month of the experiment, certain involution is noted in the lymph nodes. Further regeneration of the pancreatic stem and restoration of the lymph nodes structure develop nearly simultaneously.
