The aim of the work is to ascertain the character of changes in the hormonal profile (concentrations of corticosterone, insulin, and adrenocorticotropic hormone) in conjunction with metabolic alterations and elevated blood pressure, which are induced in rats by restraint stress at 6th, 15th and 21st weeks of environmental space restriction. Materia...

Intermittent hypoxia has been studied for many years as a promising non-pharmacological method of cardiovascular disease prevention. Hypoxic effects are accompanied by structural and functional changes in the myocardium. There is a direct link between the duration of hypoxic exposures and the severity of left ventricular myocardial remodeling. A ra...

The aim of the work is to review the professional literature sources from the scientific database PubMed mainly for the last 20 years analyzing the modern view on approaches to experimental modeling of cognitive impairment. Materials and methods. A review of the scientific literature over the past 20 years was performed. The lack of requisite knowl...

За останні роки досягнутий особливий прогрес у розумінні значення гіпоталамічнихядер у регуляції вегетативних функцій, метаболічних процесів, а також артеріального тиску. Завдяки застосуванню імуноцитохімічних та молекулярногенетичних методів стало можливим вивчення не тільки морфології нейросекреторних клітин, але і їх зв'язків з іншими відділами...

The aim of our study was to establish the morphodensitometric features of locus coeruleus (LC) neurons nuclei in the brain stem of rats with arterial hypertension of various origin (essential – SHR and endocrine-salt hypertension (ESH)). Matherials and methods: the study was carried out on 30 mature male rats: 10 control Wistar rats, 10 Wistar rat...

Modern biomedical research conducted in scientific laboratories is a basis not only for studying the pathogenetic mechanisms of diseases formation and progression, today they are widely used for highly informative diagnostic methods development, new medicines creation, and the study of newly developed pharmaceutical compounds influence on the organ...

In is known, that one of the main regulators of the blood pressure (BP) is hypothalamus. The efficiency of the BP regulation in a changeable environment is dependable on its coherence and coordination. This intrahypothalamic coordinator is an arcuate nucleus. One of the main conditions of the proper neuronal function is combination of their functio...
