| description | Background. In the general bloodstream of the small intestine, it is common to distinguish superficially located main blood vessels that distribute blood throughout the intestinal tube, and intramural networks, represented mainly by microvascular communications of the muscular and mucous membranes.
The aim. To study the features of blood supply to the groups of lymphoid nodules (Peyer's patches) of the small intestine of albino rats.
Material and Methods. The study was performed on the basis of the injecting of a 5% solution of gelatin, colored with filtered black ink, into the bloodstream of abdominal organs of 20 white male rats. The material for the study was the specimens of the small intestine with Peyer's patches. The specimens were subjected to dehydration in alcohols with transition to pure acetone; after that they were enclosed in epoxy. Photographing of the obtained specimens was carried out using a digital camera, as well as in a binocular magnifier MBS-9, equipped with a digital photo attachment Sigeta DCM-900 9.0MP.
Results. The trophism of an individual Peyer's patch of the small intestine is provided by several passing to it from different directions nutritive arteries, which are branches of the corresponding arterial vessels segmented around the perimeter of the intestinal tube.
Conclusions. Based on the major principles of microangiology, there is reason to believe that perinodal arterial vessels are the sources of formation of radially oriented metabolic microcirculatory vessels, capillary links of which are located between the subunits of lymphoid nodules. |
