Influence of low temperatures on electrophysiological parameters of the heart

The electrophysiological changes of the heart of experimental rats after the action of general hypothermia after 10 and 30 days are considered in the work. It was found that under the action of general hypothermia for 10 days there is an increase in the duration of the QRS complex, as well as a decrease in the amplitude of the R wave and its cleavage. By day 30, these changes progress, and there is the appearance of a tooth J. These data are characteristic of hypoxic heart disease, and also confirm the manifestations of cold stress. В роботі розглянуті елнктрофізіологічні зміни серця експериментальних щурів після дії загальної гіпотермії через 10 та 30 діб. Було встановлено, що при дії загальної гіпотермії на 10 добу спостерігається збільшення тривалість QRS комплексу, а також зниження амплітуди зубця R та його розщеплення. К 30 добі ці зміни прогресують, а також спостерігається поява зубця J. Ці данні характерні для гіпоксичних уражень серця, а також підтвержують прояви холодового стресу

Analysis of liver pathologies in stray dogs in the age aspect (sectional study)

The presence of stray animals in megacities or small settlements is the result of human activity. Stray dogs are in direct contact with representatives of wild fauna, influencing the occurrence and spread of various epizootics and epidemics. Stray animals, as a part of society, can serve as a biological model for understanding the influence of the environment on the body. We conducted a sectional study of 32 dogs aged from 2 years to 10 years and older. As a result, it was found that there is no correlation between sex and liver pathologies. Liver pathologies in stray animals were observed in the period from 2 to 7 years old, with a peak at 6 years of age, by 8 years old the number of pathologies decreases almost 2–3 times. Liver cirrhosis (45%), protein dystrophy of the liver (45%), acute congestive hyperemia of the liver (19%), fatty liver dystrophy (16%) and neoplasms in the liver (13%) were recorded as often as possible in stray animals. The main causes of liver pathologies in stray animals were: stress, toxic effects of food or chemicals (poisoning), pathogens of infectious diseases, metabolic disorders, internal bleeding (car injury)

Functional and role status of obstetricians and gynecologists in the process of obstetric care.

Objective: to determine the ratio of obstetricians and gynecologists roles during childbirth. Material and Methods. The questioning of obstetricians and gynecologists in the Volgograd and Rostov region has been conducted. The population was 1181. Sample random N=300. Results. Respondents acknowledge their own responsibility in 98%. Midwives agree that a woman is the main actor in the process of childbirth, but just 52,7% consider that it is necessary to inform a woman of principle for her birthing situations and do not trust its ability to make adequate decisions (52%). Conclusion. Obstetricians and gynecologists consider themselves the main actors of the process of childbirth, although not rule out the usefulness of the participation of other health professionals, respected the autonomy of women in decision-making, but prefer a higher level of confidence on the doctor. The application of advances personalized medicine is considered necessary for 69.7% of respondents, while recognizing their lack of awareness on this issue.</p

Some features of gastric lymph glands in female and male cats of the British breed

The lymphatic system is directly involved in the gastric diseases development in animals. Pathologies of the gastrointestinal tract are in one of the first places for female cats. The purpose of the research: to study the features of topography and morphometry of gastric lymph glands in female cats 3-6 years of age. Objects of research were stomachs and gastric lymph glands from British breed female cats: 10 - aged 3-5 years, 10 - aged 3-6 years. The gastric lymph gland (right and/or left) was recorded in 80% of the animals studied. The shape was oblong, oval, and round. Dimensions: right 10,3±7,7 mm, left 8,4±6,8 mm. Features: absent in 20% of the studied male cats, can be horseshoe-shaped, spindle-shaped, can be double and lobular. The right lymph gland is slightly larger than the left. The duodenal lymph gland was recorded in 20% of animals. The shape was round. Dimensions: 12±12 mm. Features: found only in female cats, having round shape and large size. The splenic lymph gland was noted in 30% of animals. Shape: oblong and round. Dimensions: 14,7±14,7 mm. Features: registered only in male cats, has elongated shape, the largest in the group of gastric lymph glands

Rationalization for the differential diagnosis of ovarian cancer and chronic salpingoophoritis in the parameters of disintegration and network modeling changes of blood flow in uterine and ovarian arteries and veins

Analysis of ultrasonic blood flow changes in uterine and ovarian arteries and veins in 92 patients with ovarian cancer and 87 patients with chronic salpingoophoritis has allowed to identify the leading differential diagnostic criteria, which include minimum diastolic blood flow velocity, resistance index, while fast hyperemia, the index of venous outflow diastolic index and index of peripheral resistance. Based on a selection of leading differential diagnostic criteria for ovarian cancer and chronic salpingoophoritis developed a network model of differentiation of these groups of patients, streamlining the differential diagnostic process

Effect of combined oral contraceptives conaining drospirenone + ethinylestradiol on the mammary gland condition in women of reproductive age

Drospirenone, as a part of combined oral contraceptives, has an antiproliferative effect on hyperplastic processes in the organs of the female reproductive system. Individual selection of COCs taking into account the dose and properties of the gestagenic and estrogenic components allows, with contraceptive and non-contraceptive purposes, to prescribe it to women of reproductive age. Intake of COC containing drospirenone + ethinyl estradiol is not associated with impaired drug tolerance due to complaints of soreness and breast engorgement in the first 3 months. 6 months of COCs containing drospirenone + ethinyl estradiol are significantly associated with a decrease in the frequency of clinical and US-signs of dyshormonal dysplasia of the breast. © 2018 Stavropol State Medical University.

ПЕРВИННА ІНВАЛІДНІСТЬ ВНАСЛІДОК ПРОВІДНИХ ХВОРОБ СИСТЕМИ КРОВООБІГУ В УКРАЇНІ (2015-2016 РР.)

Analysing the dynamics of primary disability rates among the adult and able-bodied population of Ukraine as a result of the leading diseases of the cardiovascular system in 2015-2016 became the purpose of the study. The data of the annual statistical forms of reporting the primary disability and the activities of the medical and social expert commissions of Ukraine were used. According to the analysis the diseases of the cardiovascular system in 2016 as in the last decades stand first in the structure of the causes of primary disability among the adult population of Ukraine and the second - among the able-bodied population against the background of an increase in specific gravity of malignant neoplasms. The leading role of cardiovascular pathology in the sustainable loss of work capacity of the country's population determines the need to improve specialized cardiological, rehabilitation and medico-social care.Целью исследования стал анализ динамики показателей первичной инвалидности среди взрослого и трудоспособного населения Украины вследствие ведущих болезней системы кровообращения в 2015-2016 годах. Использованы данные ежегодных статистических форм отчетности первичной инвалидности и деятельности медико-социальных экспертных комиссий Украины. Согласно анализу болезни системы кровообращения в 2016 г. продолжают, как и в последние десятилетия, занимать первое место в структуре причин первичной инвалидности среди взрослого населения Украины и второе – среди трудоспособного на фоне повышения удельного веса злокачественных новообразований. Ведущая роль сердечно-сосудистой патологии в устойчивой потере трудоспособности населения страны определяет необходимость усовершенствования специализированной кардиологической, реабилитационной и медико-социальной помощи.Метою дослідження був аналіз динаміки показників первинної інвалідності серед дорослого та працездатного населення України внаслідок провідних хвороб системи кровообігу в 2015-2016 роках. Використані дані щорічних статистичних форм звітності первинної інвалідності та діяльності медико-соціальних експертних комісій України. Згідно з проведеним аналізом хвороби системи кровообігу в 2016р. продовжують, як і в останні десятиліття, посідати перше місце в структурі причин первинної інвалідності серед дорослого населення України і друге – серед працездатного населення на тлі підвищення питомої ваги злоякісних новоутворень. Провідна роль серцево-судинної патології в інвалідизації працездатного населення країни визначає необхідність удосконалення спеціалізованої кардіологічної, реабілітаційної і медико-соціальної допомоги
