Morphological Characteristics and Correction of Long Tubular Bone Regeneration under Chronic Hyperglycemia Influence.

Introduction: Unsatisfactory consequences of bone regeneration disorders in diabetes mellitus (DM) patients, their high prevalence, complication number, and difficulties in treatment require further study and deeper understanding of reparative osteogenesis mechanisms under chronic hyperglycemia and finding new effective and affordable approaches to their treatment. Therefore, the aim of our work was to study the histological, ultramicroscopic, and histomorphometric features of reparative osteogenesis in rats with chronic hyperglycemia (CH), as well as to investigate the possibility of platelet-rich plasma (PRP) use in a fracture area in order to correct the negative effects of CH on reparative osteogenesis processes. .

Anatomical and morphological aspects of papillae, epithelium, muscles, and glands of rats' tongue: Light, scanning, and transmission electron microscopic study.

Purpose: The purpose of this paper is to describe the research results of the morphological structure of white laboratory rats' tongue at the macro-, micro-, and ultrastructural levels by scanning, light, and transmission electron microscopy.

Results: Our results show that the tongue of these rats has a number of unique morphological features that are different from the tongue of other rodents consequently to allow identifying their species-specific features.

Conclusions: Our findings have shown the features of the tongue structure of white laboratory rats at micro-, macro-, and ultrascopic levels.
