The state of regulatory mechanisms of cerebral blood circulation in patients with tumors of the chiasm sellar region before surgical intervention is studied. The disorders of circular supply of homeostasis of the brain in carotid and vertebrobasilar basins are revealed. The necessity of control of the state of cerebral blood circulation system and pharmacological correction of its disorders before operation in these patients is noted.

The results of experimental studies made it possible to draw a conclusion on the reality of cerebral vessels reactivity recovery using drugs with primary neurometabolic activity, in particular, dimephosphone, sermion and pyracetam. The advantages of low-toxic nonauticholinesterasic organic phosphorus compounds among the correctors of regulatory mechanisms of circular provision of the brain are shown.

Abstract This paper studies the “human circulatory statues” which Salomon Reisel designed in the 1670s in order to demonstrate the circulation of the blood and its effect on the brain. It investigates how Reisel intended this project to promote Descartes’ philosophy, and how it relates to contemporary diagrammatic schematizations of the blood circulation system. It further explores Reisel’s claims concerning the epistemological and practical advantages of working with a three-dimensional model and argues that Reisel intended his statua to address the concerns of his fellow physicians and, more specifically, to help in diagnostics. I consider the background, strategy and legacy of the essays in which Reisel presented his devices, as well as their relevance to the general project of the scien­tific journal – one of the earliest – in which they appeared, the Miscellanea Curiosa. Reisel was a leading physician who acted throughout his life as a mediator between the Royal Society and the Academia Naturæ Curiosorum. His articles, the paper argues, have much to tell us much about the role played by the recently established scientific academies and their journals in shaping the transmission of early modern science and medicine, in terms both of theories and of the knowledge embodied in scientific instruments.

In order to warrant the blood supply to the nervous system it is necessary an efficient and intact blood circulation system, where the pattern of vascularization is of fundamental importance. In this way, we intend to demonstrate the tridimensional architecture and the pattern of vascularization in the region of the brain cortex of frontal and parietal lobes. There for, our proposal is to study the microvascularization of the rabbit cortex (Oryctologus cuniculus).The studies about blood irrigation of the brain regions are very important to verify the capilar nets and their relations with intensity of blood flux in specified regions of central nervous system.The articles about vascularization that uses models obtained by the injection of aloplastic materials whose viscosity is similar to the blood's that allows the difusion until the capilar net was introduced by Murakami (1971). Lametschwandter et al (1984), studied aspects of corrosion technique to microvascular models.

В данной статье описывается изучение распространенности зубочелюстных аномалий, в том числе и дистального прикуса среди детей и подростков школьного возраста. В настоящее время широко распространены зубочелюстные аномалии, в том числе дистальный прикус среди детей и подростков. Зубочелюстные аномалии приводят к функциональной патологии морфологических нарушений челюстной области. Изменения возрастно увеличиваются и сопровождаются деформацией лицевой области черепа наряду с эстетическими отклонениями.У больных часто наблюдаются нарушения положения позвоночника,функциональные изменения в системе малого кровообращения и задержка психосомтического развития.Это говорит о ранних нарушениях профилактики и несвоевременном оказании ортодонтической,зубопротезной и комплексной медицинской помощи.В связи с этим важную роль играет эпидемиологическая ситуация по зубной аномалии. исполняют информацию. Диагноз дистальной окклюзии называется боковым сегментом верхнего зубного ряда, расположенным перед боковым сегментом нижнего зубного ряда и появлением между ними дистальной стадии. Лечение и прогноз дистальной окклюзии зубного ряда зависит от возраста больного и характера аномалии [1] The article is devoted to the study of the prevalence of dentition anomalies, including distal occlusion among children and adolescents of school age. Currently, dental anomalies, including distal bite, are widespread among children and adolescents. Dental anomalies lead to functional pathology of morphological disorders of the maxillary region. The changes increase with age and are accompanied by deformation of the facial region of the skull along with aesthetic deviations. Patients often have disorders of the spine position, functional changes in the small blood circulation system and delayed psychosomal development.It tells about the early breaches of the prevention of and untimely provision of orthodontic, prosthodontic and comprehensive medical care.In this regard, an important role is played by the epidemiological situation of dental anomalies. execute information. The diagnosis of distal occlusion is called the lateral segment of the upper dentition, located in front of the lateral segment of the lower dentition and the appearance of the distal stage between them. Treatment and prognosis of distal occlusion of the dentition depends on the patient's age and the nature of the anomalies [1].

A pulsatile circulation system has been built to simulate aortic blood flow. The system has both upstream and downstream compliances and resistances to simulate the elasticity and resistances of blood circulation system. Influences of the compliances and resistances on the pulsatile pressure waveforms have been systematically studied using this system. We found that in absence of the compliances and the downstream resistance, it results in an oversize negative pulsation to the pressure waveforms. The downstream resistance hardly affects the structure of the pressure waveforms, whereas the mean amplitude of pressure increases along with the downstream resistance. The compliance can reduce the peak value of the pressure, which is unrelated to the location of the compliance but related to the elasticity in the system. With fixed upstream system elasticity, the pressure waveform is more stable.
