Introduction. The application of modern methods for assessing the morphofunctional state of the endometrium to verify and study the expression of sex steroid hormones, proinflammatory markers and markers of angiogenesis using confocal laser scanning microscopy will allow an objective study of the role of studied markers in the pathogenesis of the endometrial dysfunction. The aim of the study was to evaluate the expression of ER and PR receptors in endometrium in patients with endometrial dysfunction. Material and methods. Endometrial biopsy specimens obtained with the aid of a pile-biopsy or a scraping from the uterine cavity are used to conduct the method of immunofluorescent confocal laser scanning microscopy. It is possible to use both cryostat material and paraffin blocks to provide the immunohistochemical analysis. Monoclonal antibodies to ER (1 : 60, Dako, Denmark) and PR (1 : 50, Dako, Denmark) are used as primary antibodies, antibodies conjugated with fluorochrome Alexa Fluor 647 (1 : 1000, Abcam, England) are used as secondary antibodies). Hoechst 33258 (Sigma, USA) is used for staining of cell nuclei. Results. A method of confocal laser scanning microscopy makes it possible to conduct qualitative and quantitative evaluation of the studied markers in different structures of the endometrium.

Cuticular Structures

The morphology of the copulatory apparatus and associated cuticular structures in Planorbis planorbis was studied by light microscopy, SEM, TEM and confocal laser scanning microscopy. The significance of these cuticular structures for the taxonomic status of the species and for the systematics of the family Planorbidae in general is discussed.

Following furcal perforation, bacteria may colonize the defect and cause inflammation and periodontal destruction. This study used confocal laser scanning microscopy (CLSM) to evaluate Enterococcus faecalis colonization and proliferation in furcal perforations repaired with different materials. Furcal perforations created in 55 extracted human mandibular molars were repaired using either MTA-Angelus, Endocem, or Biodentine and coronally subjected to E. faecalis suspension for 21 days. The specimens were then stained using a LIVE/DEAD Viability Kit and visualized by CLSM. The minimum and maximum depths of bacterial penetration into the dentinal tubules were 159 and 1790 μM, respectively, with a mean of 713 μM. There were significantly more live than dead bacteria inside the dentinal tubules (p = 0.0023) in all groups, and all three repair materials exhibited a similarly sized stained area (p = 0.083). However, there were significant differences in the numbers of dead bacteria at the circumference of the perforation defect (p = 0.0041), with a significantly higher ratio of live to dead bacteria in the MTA-Angelus group (p = 0.001). Following perforation repair, bacteria may colonize the interface between the repair material and dentin and may penetrate through the dentinal tubules. The type of repair material has a significant effect on the viability of the colonizing bacteria.
