BACKGROUND Orexins are neuromediators that help regulate many different physiological processes; however, their role in regulating immune system functioning is unclear. This study sought to investigate the distribution of orexin in hypothalamic orexin-containing neurons during the first 6 hours after an intravenous injection of a lipopolysaccharide. (More)
BACKGROUND The goal was to assess changes in natural killer (NK) cell activity and the number of c-Fos-positive cells in hypothalamic structures induced by painful electrical stimulation and to use extremely high-frequency (EHF) irradiation of the skin to modulate these processes. MATERIAL/METHODS Experiments were performed on Wistar rats subjected to(More)
OBJECTIVES The purpose of this study was to determine: 1) The spatial pattern of c-fos gene expression in rat hypothalamic neurons after exposure to NMS and 2) The expression of c-fos gene after combined exposure to NMS and EHF irradiation of the rat skin. METHODS The experiments were performed on 28 male adult Sprague-Dawley rats. After rats were(More)
A morphometric analysis of hypothalamic cells containing c-Fos-like protein detected by an indirect immunoperoxidase method was carried out to clarify the responses to movement restriction and skin electromagnetic high frequency (EHF) irradiation (7.1mm, 42.2GHz, 20mW output power) simultaneously to three acupuncture projection areas. The morphometry of(More)
C-fos gene expression induced in cells in specifi c hypothalamic structures by noxious mechanical stimulation and it's modifi cation by exposure of the skin to extremely high frequency irradiation Abstract OBJECTIVES : The purpose of this study was to determine: 1. The spatial pattern of c-fos gene expression in rat hypothalamic neurons after exposure to(More)
Orexins are neuromediators that participate in the regulation of feeding behavior, energy metabolism, circadian rhythms and perception of pain. The aim of the present study was to clarify the responses of the hypothalamic orexin-containing neurons to an intraperitoneal injection of cyclophosphamide (CPA), extremely high frequency (EHF)-electromagnetic(More)
C-fos gene expression was studied as a marker of nervous cells activation in the rat spinal cord and brain cells under different conditions (different kinds of narcosis). Using of 1.5% light halothane narcosis allowed the detection of c-Fos-like proteins expression in the spinal cord cells only. Under initial 1.5% halothane narcosis, c-Fos-like proteins(More)
Studies of the activation pattern of hypothalamic cells upon electric painful stimulation have revealed an increase in the counts of c-Fos-positive cells (72.02-98.95%) predominantly of a size ranging from 10 to 50 microm2. EHF irradiation of the skin activates hypothalamic cells of the size ranging from 10 to 70 microm2 in the paraventricular, dorsomedial(More)
