Histoultramicroscopic Investigation of the Rats’ Thymus (Experimental Data)

Aim: The research paper presents the characteristic of cytoarchitectonics thymus intact white mature male laboratory rats. Topicality study is due to need clarify data on contribution each type cells in formation its structure. aim was determine specifics localization and ultramicroscopic structure Wistar Material Methods: conducted using histological methods 10 rats, weighing 130-150 g. Semi-thin (0.5-1 μm) ultrathin (0.05-0.2 sections were made a microtome UMTP-4 (Ukraine), which stained with 1% methylene blue solution addition sodium tetraborate solution. Histological analysis photographic recording performed Olympus light microscope (Japan) DSM 510 camcorder magnification 1000 times. Results: With detailed semi-thin lobules clearly identified. features epithelial, mesenchymal, vascular hematopoietic determined from point view their functional loads interactions. Conclusion: described structural peculiarities components relative location different zones reflect significant organ polymorphism, must be taken into account order achieve required level objectivity result evaluation simulated biomedical experiments.
