Влияние экзогенного серотонина на усиление вагусных реакций толстой кишки

This study is dedicated to serotoninergic structures of the colon. Experiments were performed in 35 Chinchilla rabbits under general anesthesia, mechanical ventilation, bilateral vagotomy. Mechanical and electrical activity of the ascending colon was recorded during electrical stimulation of the peripheral part of the right n. vagi in intact animals and after serotonin adipate injection. It was found that serotonin potentiates vagal effects of the colon, but without effect on duration of reaction. Concluded that the serotoninergic structures of the colon are able to control the parasympathetic portion of the autonomic nervous system.Работа посвящена изучению серотонинергических структур толстой кишки. Опыты поставили на 35 кроликах: в условиях хирургической стадии наркоза, ИВЛ, двухсторонней ваготомии. Регистрировали механическую и электрическую активность восходящей ободочной кишки. В эксперименте раздражали периферический отрезок блуждающего нерва у интактных животных и на фоне продолжающегося действия серотонина адипината. Установили, что серотонин усиливает вагусные эффекты толстой кишки, не влияя при этом на продолжительность стимуляторных реакций. Сделали вывод о взаимодействии серотонинореактивных структур толстой кишки с парасимпатическим отделом вегетативной нервной системы

Method for noninvasive diagnosis of functional state disorders in operators with the smooth pursuit test

The article describes a videooculographic method to detect functional state disorders in operators in the target tracking test. The method is an improved version of the smooth pursuit test and can be used to detect and to estimate the effects of various adverse factors on operators in laboratory experiments. The method is noninvasive, allows a continuous data recording for a long period of time with the subject in comfortable conditions, and may employ various videooculographic devices (including portable and low-cost models). As an example, a series of experiments was performed to detect the negative effects of alcohol intoxication. A linear relationship was observed between changes in parameters of oculomotor reactions and changes in reaction time to the target stimulus. © 2017, Pleiades Publishing, Inc
