Comparative pharmacoepidemiological assessment of antianginal, antiplatelet and lipid-lowering drugs in patients with stable angina in outpatient practice in Kursk and Chisinau

Aim. To study structure of medical purposes of anti-anginal, antiplatelet and hypolipidemic means at coronary heart disease patients in ambulatory practice of Kursk (Russian Federation) and Chisinau (Republic of Moldova). Materials and methods. During the period from October, 2017 to January, 2018 as a one-stage descriptive research, questioning of doctors of the medical organizations of Kursk and Chisinau was carried out. Questionnaires included questions on pharmacoepidemiological aspects of purpose of antianginal, antiplatelet and hypolipidemic means. Total number of respondents was 132, of them 66 (2 cardiologists and 64 therapists) - in Kursk and 66 (10 cardiologists and 56 therapists) - in Chisinau. Results. Doctors of Kursk and Chisinau have no statistically significant differences in structure of appointments of the main groups of anti-anginal means, antiplatelet and hypolipidemic drugs. The tendency to more frequent use of blockers of calcium channels and nitrovazodilatator among doctors of Chisinau while in structure of appointments of doctors of Kursk some prevalence of a trimetazidin, antiagregants and statines was noted was noted (p>0.05). Leaders in group of beta blockers were bisoprolol and metoprolol in the conditions of the pharmaceutical market of Kursk and Chisinau. Priority of the choice of blockers of calcium channels authentically differed in the considered regions only on a felodipin - in Kursk appointed it to a thicket (p

Hypertension in dogs and cats: Causes and effects

During the nineties of the past century, several authors underscored the necessity of measuring blood pressure during a regular clinical examination of veterinary patients, because hypertension occurs as an accessory symptom in the course of diseased conditions. In addition to blood pressure measurements, most authors believe that it is necessary also to examine intraocular pressure, like in human medicine. Hypertension can be defined as a chronic increase of the systolic and diastolic blood pressure. Systemic blood pressure is proportionate to the heart rate and total peripheral resistance, while physiological control depends on the reninangiotensin system, aldosterone, prostaglandin, adrenergic and neurogenic factors. Some other factors can also have an influence on the measured values of blood pressure (such as age, sex, race, temperament, environment, and, in part, also how and where the pressure measurement was taken). It has been generally accepted in veterinary medicine than an animal can be considered hypertensive if the measured systolic/diastolic pressures are higher than 180/100 mm Hg. Hypertension can be primary (sometimes also defined as essential or idiopathic) when it is a consequence of several factors which include heart, neurological, kidney, endocrine, and metabolic aspects. Hypertension is defined as secondary when it occurs as a consequence of certain chronic disorders (such as hyperthyroidism, hypothyroidism, hyperadrenocorticism, pheochromocytoma, and diabetes mellitus). Blood pressure can be measured in animals using direct or indirect methods. The oscilometric and the ultrasonographic methods are equally used in the world today. Following detailed studies by large numbers of authors, the physiological frameworks of blood pressure in animals have been precisely determined. Different treatments are applied in the therapy of hypertension in animals, such as: restrictive diets, diuretics, a, and (3 blockers, blockers of calcium channels, vasodilators, ACE inhibitors. Hypertension can also be a state that requires emergency treatment, when it is resolved with aggressive therapy.

Studies on the mechanism of embryonic frog nerve orientation in a small applied electric field

The mechanism of nerve orientation in an applied electric field has been investigated using a number of pharmacological agents. Galvanotropism may depend on redistribution within the plasma membrane of integral membrane proteins (IMP); blocking this with concanavalin A inhibited orientation. Orientation may depend also on an influx of Ca2+; Co2+ and La3+ blockade of calcium channels inhibited turning in an electric field. Organic blockers of calcium channels did not influence orientation, suggesting that L-type Ca2+ channels may not be present at the growth cone. Procedures that may induce asymmetric entry of Ca2+ on the anodal side of cells caused a reversal of normal galvanotropism, with growth directed towards the anode. This may implicate local levels of cytoplasmic Ca2+ within the growth cone in controlling turning behaviour. An asymmetric distribution of filopodia precedes and may predict the direction of nerve growth in an electric field. Various pharmacological agents perturbed the distribution of filopodia in such a way that this did not reflect subsequent orientation. It is suggested that, normally, local Ca2+ increases and an asymmetry of filopodia operate together in determining orientation, but that filopodial activity is subordinate to and can be overriden by local Ca2+ levels in the growth cone. In addition, two of the drug treatments markedly increased rates of nerve growth, which may be of importance in nerve regeneration.
