To determine whether an increased level of progesterone in adult female rats after acute ethanol treatment, described previously in our study, is the result of activation of adrenal glands, we analyzed adrenal cortex morphologically and measured serum levels of corticosterone and progesterone in ovariectomized rats. In addition, a possible involvement of(More)
Growth factors play an important role in orchestrating and enabling the cellular responses required for successful wound healing. In the present study, rat surgical incision was used to investigate insulin-like growth factor-I (IGF-I) expression in skin cells as well as its systemic and cutaneous tissue concentrations during acute phase of wound healing.(More)
Psychological stress affects different physiological processes including haematopoiesis. However, erythropoietic effects of chronic psychological stress remain largely unknown. The adult spleen contains a distinct microenvironment favourable for rapid expansion of erythroid progenitors in response to stressful stimuli, and emerging evidence suggests that(More)
Macrophage migration inhibitory factor is a well-known proinflammatory cytokine that is released during systemic stress response. Although MIF can affect erythrocyte production, the role of this cytokine in stress-induced erythropoiesis is completely unknown. To extend our previous findings showing that chronic psychological stress stimulates extramedullary(More)
The aim of our study was to investigate the appearance, density and distribution of ghrelin cells and GHS-R1a and GHS-R1b in the human stomach and duodenum during prenatal and early postnatal development. We examined chromogranin-A and ghrelin cells in duodenum, and GHS-R1a and GHS-R1b expression in stomach and duodenum by immunohistochemistry in embryos,(More)
BACKGROUND This study was performed to investigate expression and distribution of glucocorticoid receptor (GR) in the rat adrenal cortex, acute effect of ethanol on its expression and possible role of endogenous nitric oxide (NO) in this phenomenon. METHODS Adult female Wistar rats showing diestrus day 1 were treated with: a) ethanol (2 or 4 g/kg body(More)
Isolated rat adrenal medulla was analyzed by light and electron microscope after an acute (60 min) exposure to high ambient temperature (38°C). Under these conditions there was a significant rise in plasma adrenaline and noradrenaline. Stereological investigation by light microscopy showed a significant decrease in volume density of cells and an increase in(More)
OBJECTIVE Nitric oxide (NO) is known as a regulator of inflammation and immunity. The purpose of this study was to investigate the influence of this signal molecule on the rat immunoglobulin A (IgA) system using Nomega-nitro-L-arginine-methyl ester (L-NAME), which inhibits the activity of all isoforms of NO synthase. METHODS The experiments were performed(More)
The purpose of this study was to investigate the acute effect of ethanol on mucosa-associated lymphoid tissue at the level of Peyer's patches and the intestinal lamina propria in female rats and to determine whether this action of ethanol is modulated during the estrous cycle. Adult female rats showing proestrus or diestrus day 1 were treated(More)
