[Submandibular lymph nodes of rats with arterial hypertension after mandible bone damage]

The structure of submandibular lymph nodes (LN) from rats with arterial hypertension (AH) and normal pressure after mandible damage was investigated by methods of light microscopy. It was revealed that in submandibular LN of both compared groups of animals after induction of inflammatory reaction cortical field was extended, bulk density of lymphoid nodules without reproductive centres was increased, in nodules with centres mantle was extended and germinative centres were decreased. In all structures of LN the numbers of mitosis, imrnuno - and plasmoblasts were increased, the contents of reticular cells and macrophages were increased only to 4-5 week. In structure of LN from rats with normal arterial pressure and with AH the volume of sinus system statistically significantly differed: animals with AH had more volume of sinuses on all points of observation. Inflammation in the conditions of AH the distinction in cellular content of various zones of LN were connected with occurrence or higher number of erythrocytes.
