Optimization of Functional State of the Liver in Patients with Chd on the Background of Rosuvastatin Intake
No full textIn 2019, 18.6 million people died of cardiovascular diseases (CVDs) worldwide. Coronary heart disease (CHD) is the leading cause of death from CVDs. One of the main risk factors for atherosclerosis and its complications is hyperlipidemia. The progress achieved is due in no small part to the emergence of a new class of hypolipidemic drugs belonging to the group of statins - HMG-CoA reductase inhibitors. Statins are the most effective means of combating atherosclerosis, having proven the ability to slow or completely stop its progression. Usually, statin therapy is well tolerated, but side effects can develop, including elevation of hepatic enzymes - aminotransferases. In this regard, the administration of statins together with hepatoprotective drugs, such as milk thistle extract leads to a decrease in the side effects of hypolipidemic therapy in patients with CHD
Features of the Course of Arterial Hypertension in Elderly Patients with Bronchial Asthma
No full textIn order to identify the clinical and functional features of the combined course of bronchial asthma (BA) and arterial hypertension (AH), 90 patients with AH were examined. 60 of them were diagnosed with asthma of varying severity. All patients underwent daily monitoring of blood pressure (SMAD), spirography, echocardiographic examination (EchoCG). The results of the work indicate the presence of pronounced pathological changes in blood pressure (BP), external respiration function (FVD), as well as functional and geometric indicators of heart activity in the group of elderly patients with AD
Clinical Pathophysiology and Anatomy of Acute Pain
No full textAccording to the definition of the International Association for the Study of Pain, hyperalgesia means "an excessive reaction to moderate nociceptive stimulation". Primary hyperalgesia or peripheral sensitization is a reflection of activation and sensitization of nociceptive A-delta fibers and terminal windows of polymodal C-fibers in injured tissues. The basis of secondary hyperalgesia or central sensitization is spinal neuroplasticity and facilitating the transfer of nociceptive information to supraspinal structures
Early Diagnosis of Cervical Cancer Caused by HPV
No full textCervical cancer is an oncological disease that affects the mucous membrane of the cervix.The disease most often proceeds without symptoms. They appear only with the development of complications.In these cases, the signs of cervical cancer include: spotting from the genital tract, chronic pelvic and lower back pain, menstrual cycle disorders, urination and defecation. In most cases, HPV types 16 and 18 are detected. HPV infection in the population, according to various studies, ranges from 80 to 95%. It is important to understand that it is not the fact of detecting a papillomavirus infection that is crucial, but the duration of its presence in the body.Cancer is preceded by the occurrence of precancerous diseases called intraepithelial neoplasia or cervical dysplasia. This is a precancerous disease that often turns into cancer without treatment. The development of oncopathology from the stage of dysplasia to cancer takes 7-10 years. During this period, the disease does not manifest itself clinically in any way
Effect of Hemodialysis Therapy on Heart Rhythm
No full textAccording to the US Renal Disease Registry, the five-year survival rate in the general population of patients on hemodialysis is 33.4% [U. S. Renal Data System, 2009]. More than half of the deaths of patients on renal replacement therapy are due to cardiovascular pathology, the mortality from which in patients on hemodialysis is 30-35 times higher compared to the general population [Zavy A.S. et al., 1998; Herzog S.A., 2003; U.S. Renal Data System, 2009]. A significant proportion of deaths in patients with end-stage renal disease receiving hemodialysis treatment are attributed to those associated with coronary heart disease [Foley R.N. et al., 1998a; Sarnak M.J. et al., 2003; Cheung A.K. et al., 2004]. The theoretical method of research was used. Many articles and dissertations by international scientists were analyzed, which were based on various books, dissertations, as well as electronic journals
The Effect of Depakin Physiologically and Histology on the Kidney of Pregnant Female White Rats and the Investigation of the Protective Role of the Portulacea Oleracea Plant
No full textAim: Knowledge of histological and physiological changes of the kidneys in female rats treated with lepipakine, and the possible protective role of the use of Portulacea Oleracea plant extract.
Materials and Methods: Female rats were divided into six groups (1) control group (2) treatment group with therapeutic dose (0.5mg/kg), depakine (3) double dose treatment group (1mg/kg) of depakine.(4) Portulacea Oleracea -aqueous extract group at 2mg/kg, (5) therapeutic dose of depakine (0.5mg/kg) with Portulacea Oleracea -aqueous extract (2mg/kg), (6) double dose of depakine (1mg/kg) with Portulacea Oleracea -aqueous extract (2mg/kg) Any day for 18 days, and the female rats were dissected on the 19th day of pregnancy, and the kidneys were taken for histological examination and blood was drawn from the heart for urea and creatinine tests.
Results: Laboratory examination of kidney function showed a significant difference P001, where high urea and creatine were observed in the two groups treated with depakine with different dose concentrations, and the aqueous extract of the Portulacea Oleracea plant showed its protective role in reducing creatine and urea levels as shown in the table(1-1). The histological examination showed that Depakin led to histological changes in the kidneys of the therapeutic and double dose group of the drug, which was represented by atrophy in the glomerulus, hemorrhage within the tissue area and the appearance of a plug in the tubules in addition to thickening in the vessel as shown in the picture (A, B, C). Compared to the control group . As for the plant extract, the Portulacea Oleracea contributed to reducing the negative effects of the drug as shown in the pictures (E, F, G).
Conclusion: The drug led to many histological and physiological changes in the kidneys, and the aqueous extract of the Portulacea Oleracea plant also contributed to improving the kidney injury caused by the drug by reducing urea and creatinine levels, and reducing renal histological damage
Grammatical Meanings of Plusquamperfect Tense and its Contextual Analysis
No full textThe article examines the polysemy of plusquamperfekt in German. Plusquamperfekt is used to express the long past tense, and also has the property of relative usage. The interaction of two or more tenses in the same context is called the relative tenses of verbs. In this case, the connection between two or more actions is not focused on the moment of speech, but enters into a mutual connection. Linguists' theories about polysemy plusquamperfekt are substantiated and contextually analyzed using examples from German works of art
