The ever-increasing harmful effect of endo- (products of inflammatory processes of genital tissues) and exogenous factors (environmental conditions) on the body of women and animals (cows) leads to a substantial decrease in ova fertilisation during mating and artificial insemination. Therefore, the purpose of this study was to identify changes in the signs of physical condition (colour, consistency, fluidity, impurities, etc.) and ratios (homeostasis) of H2O mass, organic (OS) and inorganic (IS) substances of uterine-vaginal mucus (UVM) should be used to assess their harmful effect on the fertilisation of cows after their first insemination. The following methods were used for this study: ocular estimate of the physical condition of freshly obtained mucus; gravimetric assessment of the features of changed mass parameters of its dry residue (DR) components; mathematical and statistical analysis of certain indicators. Determined by the gravimetric method, the features of the imbalance of mass (g, mg), its distribution (%) and ratios (Im:1, Ic:1) in the system of the “medium — substance” type due to the harmful effects of endogenous factors (products of inflammatory processes) indicate that the secretions of the genitals released during oestrus are characterised not only by changes in signs, but also ±2-4 times different from the norm (control) indicators of the mass of components. Under such circumstances, the distribution of substances in the DR samples of the experimental group is expressed by the series, where the mass OS1˃IS˃OS2, but in the control group — OS1˃IS˃OS2. This means that the products of inflammatory processes released by the genitals of cows change the norm of homeostasis of the mass (distribution of components) of OS and IS of the biological system of the “medium — substance” type. Indicators of the obtained mass ratios between component pairs H2O: DR; H2O: OS2, H2O: OS1,H2O: IS (control group — 63:1, 586:1, 231:1, 109:1; experiment group — 42:1, 310:1, 87:1, 112:1), except for the H2O: IS pair (P˂0.05), indicate the presence of probable changes in the homeostasis of OS and IS in the “H2O — components” system. The high probability (P˂0.02; ˂0.001) of the detected changes is inherent in the “DR –components” system, namely: if the average ratio indicators of pairs DR: OS2; DR: OS1; DR: IS samples of the control group are 9:1, 4:1, 2:1, then the same indicators in the experimental group are 7:1, 3:1, 2:1, respectively

Непліддя є однією з найактуальніших медико-соціальних проблем у всьому світі.
Чоловічі чинники непліддя сягають 50 % усіх випадків. Приблизно 7 % чоловіків у всьому світі страждають від непліддя. Сперматозоїди надзвичайно вразливі до окиснювального ураження. Оксидативний стрес призводить до пошкодження аксонем і збільшення морфологічних дефектів середньої частини сперматозоїдів, що призводить до зниження їх рухливості. Метою дослідження є оцінка зв’язку між рухливістю сперматозоїдів, активністю глутатіонової антиоксидантної системи та концентрацією цитокінів. Обстежено 68 здорових чоловіків, які були розподілені на дві групи за відсотком рухомих сперматозоїди через 1 годину після отримання еякуляту: низька рухливість (НР, n=32) і висока рухливість (ВР, n=36). Рівень малонового діальдегіду (MDA) був в 1,3 раза (p<0,05) вищим у групі НР порівняно з групою ВР. Середні значення IL-1β, IL-18, IFN-γ і TNF-α були також вищими у групі НР, ніж у групі ВР. Результати цього дослідження показали, що відсоток рухливих сперматозоїди через 1 годину негативно корелювали з рівнями IL-1β, IL-18 та TNFα. Нижча рухливість сперматозоїдів у здорових чоловіків пов'язана зі зниженням вмісту відновленого глутатіону та нижчою активністю GP і підвищеним рівнем цитокінів, які можуть бути пов'язані з підвищеним оксидативним стресом у сім'яній плазмі про що свідчить підвищений рівень МДА. 

 Introduction. Almost all patients, who have experienced acute manifestations of COVID-19, regardless of the severity of the acute phase of the disease, are only at the beginning of a long way to recovery. According to experts, SARS-CoV-2 infection should affect almost 80% of the world's population, so all these patients to a greater or lesser extent will need a rehabilitation of certain manifestations of postcovid syndrome.

Purpose: to study the effectiveness of rehabilitation program and the dynamics of cognitive impair- ment and manifestations of chronic fatigue syndrome in patients after coronavirus disease.

Methods: The study design included 60 patients after SARS-Cov-2 infection. Among the examined patients there were 26 (43,3%) women and 34 (56,7%) men. An average age of the patients was 43,9±1,08 years. Patients were referred to the Department of Physical Rehabilitation after corona- virus disease with chronic fatigue and cognitive disorders syndromes. Accordingly, all patients, who participated in the study, were divided into two groups: group I - 28 patients with a general condition of moderate severity at the hospital stage and 32 patients - group II, with severe course of the disease and oxygen demand at the hospital stage. Depending on the duration of rehabilitation, two observation periods were used - on the 7th and 14th day of rehabilitation program.

Results: It has been proven, that patients, who didn’t need oxygen, were complaining about anos- mia, cephalgia, cognitive impairment, increased anxiety and fatigue. Dysgeusia, dyssomnia, and depression were more common in patients, requiring oxygen therapy at the hospital stage. Rehabil- itation program eliminated cognitive dysfunction, depression, cephalgia, drowsiness and dyssom- nia on the 7th day in patients, who did not require oxygen therapy (p>0,05), and in patients, who needed oxygen therapy - on the 14th day of the rehabilitation program (p>0,05). However, 2 (6,3%) and 3 (9,4%) patients, who needed oxygen therapy, even after 14 days of rehabilitation had mani- festations of minor recurrent headache and drowsiness.

Conclusion: Thus, patients after coronavirus disease, who needed oxygen therapy at the hospital stage, need long-term rehabilitation program.
