Damage to the endothelium of pulmonary microcirculatory vessels and the development of coagulopathy are considered important elements of the pathogenesis of coronavirus infection. The purpose of the study was to determine the ultrastructural changes of the microcirculatory bed of the lungs of patients who died due to respiratory failure during the coronavirus infection, using transmission electron microscopy. In the vessels of the microcirculatory bed of the lungs of patients who died on the 14th, 20th, 22nd, and 40th days of the disease, dyscirculatory processes of varying severity were observed in the form of severe hyperemia, stasis, microthrombi, and alternative changes in the endothelium. Damage to the vessels of the microcirculatory bed was accompanied by pronounced coagulopathy and endotheliitis, which are key aspects of the pathogenesis and thanatogenesis of coronavirus infection.

The influence of obesity (with and without passive smoking) on the formation of pathomorphological changes in the lungs was studied in 4 groups of sexually mature male rats: the control group (CL), the group with isolated alimentary obesity (O), the group exposed to isolated exposure to tobacco smoke (S), the group with combined dietary obesity and exposure to tobacco smoke (OS) after 4 months of the experiment. The morphological changes found in the CL group were insignificant. In group S, the presence of changes characteristic of chronic bronchitis and focal emphysema was established. Pathomorphological changes typical for the chronic obstructive pulmonary disease were found in group O: chronic bronchitis, initial manifestations of
bronchiectasis formation, pulmonary emphysema, focal pneumosclerosis, and initial manifestations of pulmonary hypertension.
In the OS group, the changes were not qualitatively different from those in the O group. It was found that the changes characteristic of chronic obstructive pulmonary disease developed in rats with simulated obesity, regardless of whether the smoking model was used
