The Impact of Toxic Stress on the Morphofunctional State of the Hypothalamic Arcuate Nucleus in the Conditions of the Changed Mode of Light Exposure

Abstract: Резюме. Цель. Аркуатное ядро (АЯ) гипоталамуса является одним из интегративных центров, ответ-ственных за энергетический метаболизм млекопитающих. Изучена реакция АЯ белых крыс на токсиче-ский стресс, вызванный введением хлорида кадмия в условиях естественного освещения, световой и темновой деприваций. Методы. Токсикант вводили перорально в дозе 2 мг на 100 г массы тела еже-дневно в течение 15 дней после месяца адаптации к искусственному фоторежиму. Синтетическую ак-тивность оценивали методом кариолометрии на … Show more

“…The mechanisms of the unfavorable toxic effects of cadmium were studied in more detail in animal experiments. A significant influence of the cadmium chloride introduction on the hypothalamic arcuate nucleus morphofunctional state has been shown in particular, involving inhibition of its synthetic activity [11]. The passage of cadmium through the blood-brain barrier and its effects on the balance of sleep and wakefulness has been shown in acute and chronic experiment on Wistar rats; intraperitoneal injection of cadmium chloride during 9 days were accompanied by epileptiform activity on the EEG with increasing of the audiogenic convulsions predisposition [23].…”
