The amygdaloid body is a telencephalic structure belonging to the limbic system. The amygdaloid body consists of the two main nuclear groups: corticomedial and basolateral. The former-phylogenetically older group is composed of the central, medial, and cortical nuclei, while the latter, phylogenetically younger one, of the lateral, basolateral and(More)
Many hypothalamic nuclei are involved in the regulation of food intake and energy homeostasis. An ultrastructural investigation of the hypothalamic ventromedial nucleus (VMN), a hypothetical "satiety centre" was performed to explore the morphological basis of altered feeding behaviour of old rats in an experimental model of fasting/refeeding. Young (5(More)
OBJECTIVE The purpose of this study was to examine protective and antioxidative effect of stilbene derivatives, resveratrol and diethylstilbestrol, in experimental acute pancreatitis (EAP). METHODS EAP was induced in male Wistar rats by retrograde injection of tert-butyl hydroperoxide (ButOOH) solution, a well-known prooxidant agent, into the common bile(More)
The direct and accurate estimation of nitric dioxide levels is an extremely laborious and technically demanding procedure in the molecular diagnostics of inflammatory processes. The aim of this work is to demonstrate that a stop-flow technique utilizing a specific spectroscopic biosensor can be used for detection of nanomolar quantities of NO(2) in(More)
INTRODUCTION A number of observations suggest that vitamin D plays an important role in maintaining normal cardiovascular function, through its receptors in cardiac muscle or in aortal smooth muscle cells (SMCs). The purpose of this study was to determine the effect of vitamin D active metabolite--calcitriol [1,25(OH)2D3] on aortal SMCs. MATERIAL AND(More)
For the first time, a direct sensitive method of *NO(2) detection and measurement in biological material has been established. It is based on the interaction of this radical with the coordination compound of Cr(III) with aminodeoxysugar as biosensor. Our new method makes it possible to precisely assess *NO(2) level in experimental acute necrotizing(More)
In this study, 15 kinds of powders with different compression mechanisms were used in the process of filling-binding substances in tablets with pellets. Applied substances possessed dominant brittle time-independent mechanism or time-dependent viscoplastic, viscoelastic mechanism of compression. Using 6 kN compression force in a single-stroke tablet press(More)
A dark type degeneration of axon terminals was observed in the dorsocaudal part of the claustrum following lesions of the visual cortex. Most of the degenerating axon terminals had synapses mainly with dendritic spines (64.1%) and small dendrites (25.1%). Only 5.8% of degenerating axon terminals formed synaptic contacts with medium-sized dendrites, 1.0%(More)
Data obtained by using ultrastructural and morphometric approaches revealed three types of neurons in the cat visual claustrum. The most numerous were medium-sized and large ones. They formed 3/4 of the cell population. The ultrastructural properties of those cell types were largely similar. Their cell bodies were oval, round, fusiform or triangular and(More)
The arcuate nucleus of the hypothalamus (ARH) is involved in the control of energy homeostasis. This is the first study on the ultrastructural response of ARH neurons in aged rats after short-term fasting and subsequent refeeding. Male Wistar rats (24 weeks old) were fasted for 48 or 96 hours and were then refed for 24 hours. The controls were normally fed.(More)
