The members of the Russian crew of the ISS-74, Sergei Koud-Sverchkov and Sergei Mikayev, are currently undergoing training for expedition, in particular to put into practice the practical skills they need to carry out spatial experiences.
For several years. Furthermore, the cosmonauts of Roscosmos have participated in a vast medico-biological study entitled “Neuroimmunity”, which aims to collect data on the physiological adaptation of the human body to the conditions of a long-term space flight and to assess the impact of stress on immunity. Moreover, This study is conducted by specialists from the Cosmonaut Training cosmonauts iss-74 mission preparing “neuroimmunity” Center (TSPK) and the Institute of Medico-Biological Problems (IMBP).
« Our body has several systems that influence each other. Similarly, It is above all the central nervous system. However, the autonomous nervous system, as well as the purimergic (intercellular) and endocannabinoid systems. Furthermore, All react to the factors linked to space flights, such as weightlessness overloads, isolation, artificial habitats and many others. For example, They affect the emotional. Furthermore, cognitive state of a person and can lead to the development of asthenic syndrome and, possibly, of chronic stress, affecting the immune system, ”explains Galina VasilyevaDirector of the IMBP laboratory and doctoral student in medical sciences.
To analyze changes in the immune system, cosmonauts will have to do several exams on board independently. Moreover, During the practical lesson. Sergueï koud-Sverchkov et Sergueï Mikayev studied the functioning of the Kosmocard device, designed to record variations in the heart rate, provided cosmonauts iss-74 mission preparing “neuroimmunity” with an oximeter of pulse, necessary to measure the oxygenation of the blood, and an actimeter.
But the most important object of research for specialists is venous blood. whose crew will itself have to take samples aboard the ISS. The cosmonauts also worked this competence during a practical course under the direction and direct participation of Natalia BakarskayaTSPK teacher.
Natalia Petrovna described in detail the course of the procedure before, during and after its execution. The cosmonauts then carried out blood samples in turn from a medical model. After this training, Sergei Mikayev, who had no experience of venous samples, managed to take the teacher’s blood.
« Most of the experience is not complicated, directors have prepared clear and logical instructions. As for the practical part of the venous sample. I failed to reach the vein the first time, but I succeeded. The practice is important. you have cosmonauts iss-74 mission preparing “neuroimmunity” to know everything yourself to avoid any problem during the flight in the future Shared Sergei Mikayev.
In orbit. the cosmonauts will also have to treat the blood in order to keep it until their return to earth. Sergei Koud-Sverchkov. Sergei Mikayev took turns to prepare blood smear on blades, then centrifug the blood (a process that separates blood into fractions).
Sergei Koud-Sverchkov has already participated in this experience during his previous flight. can compare the preparation process and subsequent implementation on board:
« Training is designed to minimize differences. The same medical devices and supplies are used. The only condition impossible to reproduce here is weightlessness. On board, there are nuances concerning the subject fixation and the safety of the instruments. It is particularly important that we take blood. centrifugions and use the same protocols on earth and space “Said the cosmonaut.
The data obtained during this cosmonauts iss-74 mission preparing “neuroimmunity” complex study will allow the future to decipher the mechanism of modifications to the immune system. will be essential to understanding the processes of mutual influence of consciousness, stress and immunity.
This will further improve the medical. biological support of long -term orbital and interplanetary flights, and to acquire the knowledge necessary to prevent an unwanted immunological response from the organism under the influence of various extreme factors and the development of pathologies.
