PRIMORDIAL FORMS OF PEYER'S PATCHES DEVELOPED IN ALBINO RATS' SMALL INTESTINE AFTER ADMINISTRATION OF BROAD-SPECTRUM ANTIBIOTIC.

Experimental modeling of dysbacterioses associated with antibiotics is an urgent issue of morphological studies. The present paper was aimed at the detection and study of the primordial forms of Peyer's patches developed in the small intestine of albino rats after administration of clarithromycin. 30 mature albino male rats weighing 200.

[STRUCTURAL FORM OF THE FOLLICLE-ASSOCIATED EPITHELIUM OF PEYERS' PATCHES OF THE ALBINO RATS' SMALL INTESTINE].

The paper was aimed at detailed specification of microscopic structure of the intestinal epithelium, associated with lymphoid nodules of the Peyer's patches of the albino rats' small intestine. 30 mature albino male rats weighted 200,0±20,0 g were involved into the study. Slices of the small intestine with Peyer's patches have been analyzed.

[Structure of teeth in mature ovarian teratoma].

Material And Methods: The authors investigated three mature ovarian dermoid cysts that were found to contain atypically developed teeth (one tooth in one cyst; 2 teeth in another cyst, and a set of 8 teeth with jawbone fragments in the third one). Their structure was examined using the epoxy resin plastination technique to obtain plastinated sections.

Results: Some of these teratomous teeth have obvious signs of alteration in both dentin and enamel, which may be referred to as fluorosis or macular enamel hypoplasia in one case whereas other sections indicate a caries lesion.
