The study was performed from the perspective of the Bulgarian National Health Insurance Fund (NHIF) and patients. METHODS(More)
The posterior neurohypophysis (PNH)-pars intermedia complex of the wild and pond carp, Cyprinus carpio L., has been studied by light, fluorescence and electron microscopy. "Gomori-positive" neurosecretory fibres are abundant in the main trunk of the neurohypophysis as well as its roots penetrating the pars intermedia. Terminals of these fibres are in(More)
Xylene is one of the materials that could be used for synthesis of different carbon nanoparticles including perfect carbon spheres with diameters of 1 to 8 microm and ellipsoids. Its changes in the course of the pyrolytic process in a hermetically sealed stainless steal container have been examined by stopping the process at different stage of temperature(More)
Falk's histochemical fluorescent method was used to study monoamine (MA)-containing structures in isolated hypothalamus nuclei and in the neurohemal region of the medial eminence (ME) in 40 male rats under the conditions of a long-term stress (6 months) which was caused by a repeated weak electrodermal stimulation. A statistically significant decrease in(More)
Open-field behaviour and emotionally differently reinforced learning were studied in male Wistar rats with bilaterally ablated Locus coeruleus. Histochemical analysis of the hypothalamic structures was carried out. Decrease of investigating activity and attention was found as well as disturbances of learning with emotionally-negative (painful)(More)
