Abstract
The article presents the histological features of some organs of weasel family. Also described
the pathological changes during nonexudative form of peritonitis of weasel family. The studies
were carried out at the Department of General Pathology named after V. M. Koropov of Moscow
State Academy of Veterinary Medicine and Biotechnology – MBA named after K. I. Scriabin. The
objects of investigation were predatory animals weasel family both healthy and with sings of peritonitis.
There are 21 sables, 11 mink cellular content and 15 domestic ferrets. In the study complex
methodological approach was used, including classical anatomical preparation, post mortem and
histological examination.
It has been established, that abdominal wall weasel has three puffs. There are muscle layer, a
layer of dense connective tissue and serous membrane. The muscle layer is showing striated muscle
tissue with endomysium layers. In the endomysia of muscle febers of abdominal wall of the weasel
there are mast cell. Serous membrane is represented by mesothelium, which has typical structure
of single – layered squamous epithelium. Large oil seal showing of fat cells with connective tissue
layers, including lymphatic capillaries, vessels and nerve trunks. In a large oil seal single mast cell
concentrated around the vessels and in the connective tissue of the omentum observed clusters of
mast cells. Essential features of the structural organization of the stomach walls and intestinal
canal are not found, but revealed a large number of goblet cells in the mucous membrane of the
colon and small intestine and mycocytes in mucous membrane of stomach. The liver has a typical
structure, lobilarity is weakly expressed. Liver beams are shortned, hepatocytes fit snugly together,
sinusoid capillaries are broad. In morphological organization of organs of immune defense weasel
significant features are not found. In the spleen was observed a lot of white pulp. In the cortical
layer of lymph node was founded a large number of follicles. Thymus has sings age involution. Kidney
and lungs weasel has not significant features.
Predatory animals weasel family had predominantly nonexudative form of peritonitis. Under
the nonexudative peritonitis form was observed sings of acute inflammation of many organs like as
system inflammatory response syndrom.
