Biologija - Biologija ćelija i tkiva / Biology - Cell and tissue biology

Ispitivan je uticaj akutnog toplotnog stresa na histološke, imunohistohemijske, ultrastrukturne, stereološke i biohemijske karakteristike adrenokortikotropnih ćelija hipofize i ćelija nadbubrežnih žlezda pacova kao ciljnih organa hipotalamo-hipofizne-adrenalne osovine u odgovoru na dejstvo stresora. Pacovi mužjaci soja Wistar izlagani su temperaturi od 38C u komori u trajanju od 60 minuta. Životinje su nakon tretmana žrtvovane dekapitacijom u prepodnevnim časovima, u približno isto vreme, da bi se izbegao uticaj cirkadijalnog ritma na proučavane parametre. Kortikotropne ćelije adenohipofize su analizirane na nivou svetlosne i transmisione elektronske mikroskopije primenom imunohistohemijskih i stereoloških metoda. U nadbubrežnim žlezdama ispitivane su histološke i ultrastrukturne karakteristike ćelija kore i srži. Kvantitativne odlike nadbubrežnih žlezda određivane su primenom stereoloških i morfometrijskih metoda na nivou svetlosne i elektronske mikroskopije. Peptidergički neuroni (VIP, SP i NPY) u kori i srži nadbubrežnih žlezda procenjivani su imunohistohemijskim metodama. Za prikazivanje protoka krvi u nadbubrežnim žlezdama korišćena je Noveli histološka metoda bojenja. Ćelije u proliferaciji procenjivane su preko Ki-67 antigena, dok je za detekciju apoptotskih ćelija nadbubrežnih žlezdi primenjeno bojenje propidijum-jodidom. Određivane su i koncentracije adrenokortikotropnog hormona hipofize (ACTH), kao i kortikosterona, aldosterona, adrenalina i noradrenalina nadbubrežnih žlezda pacova u cirkulaciji. U hipofizi, primenjeni tretman doveo je do povećanog izlučivanja ACTH iz kortikotropnih ćelija. Ovo se na nivou svetlosne mikroskopije manifestovalo smanjenjem broja ćelija imunopozitivnih na ACTH, a na nivou elektronske mikroskopije smanjenjem broja granula u ACTH ćelijama. U skladu sa tim, biohemijski podaci pokazali su da je koncentracija ACTH u cirkulaciji povećana. U krvnim sudovima hipofize prisutna je agregacija krvnih pločica...

▼ The aim of the study was the effect of acute heat stress on the histological, immunohistochemical, ultrastructural, stereological and biochemical characteristics of corticotroph pituitary cells and cells of the adrenal glands of rats as a target organ of the hypothalamic-pituitary-adrenal axis in response to the effects of stressors. Wistar male rats were exposed to a temperature of 38°C in the chamber for 60 minutes. Animals were sacrificed by decapitation after treatment in the morning, at about the same time, in order to avoid the influence of circadian rhythm on the studied parameters. Corticotroph pituitary cells were analyzed at the level of light and by transmission electron microscopy using immunohistochemical and stereological methods. The adrenal glands were studied by histological and ultrastructural characteristics of the cells of cortex and medulla. Quantitative characteristics of the adrenal glands were determined using stereological and morphometric methods at light and electron microscopy. Peptide neurons (VIP, SP and NPY) in the cortex and medulla of the adrenal glands were assessed by immunohistochemical methods. To show the flow of blood to the adrenal glands a Novelli histological method of staining was used. The cells in proliferation were assessed by Ki-67 antigen, whereas the detection of apoptotic cells of the adrenal gland was enabled by propidium-iodide staining. The concentration of pituitary adrenocorticotropic hormone (ACTH) and corticosterone, aldosterone, adrenaline and noradrenaline in the rat adrenal gland circulation were determined. In the pituitary, the applied treatment resulted in increased secretion of ACTH from corticotroph cells. On the level of light microscopy, it was demonstrated by decreased number of immunopositive ACTH cells, and at the level of electron microscopy by reduced number of granules in the ACTH cells. Accordingly, biochemical data showed that the concentration of ACTH in the circulation increased. The blood vessels of the pituitary gland in platelet aggregation were present. In the adrenal glands changes were evident at both light and electron microscopy level. In the ZG, there was an increased synthesis and secretion of aldosterone what was showed by significant reduction in the number of lipid droplets, increasing the number of mitochondria and high levels of circulating aldosterone. The increase in concentration of circulating aldosterone is a response to dehydration caused by the exposure of animals to high temperature of the external environment. In the ZF a significant increase in the surface profile and volume of the cells were observed, particularly in cytoplasmic components, together with reduction in the number of lipid droplets, increasing number of mitochondria, and significant increase in corticosterone levels in the blood at the same time. Enlargement of cells involved in the synthesis and secretion of the stress hormone corticosterone, changing of relative abundance of components in the cells in a direction which indicates a greater…

▼ Extreme weather events are a growing focus of global climate change research. Extreme events, which occur abruptly and unpredictably, are often more detrimental to terrestrial vegetation than gradual shifts in climate. One type of event, the summer heat wave, may already be increasing in some areas of the world. Large-scale reductions in Net Primary Productivity and mortality have been reported during heat waves in forested ecosystems. Unfortunately, our understanding of how abrupt heat-stress affects woody species during heat waves lags behind our knowledge of herbaceous species that have been more widely studied in experimental manipulations. A few studies of herbaceous species also suggest that the coupling of soil heating to air heating can change the overall plant response to heat waves. To investigate air vs. air+soil heating in woody species, we manipulated the temperature of both shoots and roots separately for both white and black oak seedlings by insulating the soil during heat-stress to the shoot (35 vs. 40°C for 4 days, white oak; 35°C for 8 days, black oak). Interestingly, at moderate heat-stress temperature (35°C), net photosynthesis declined and internal CO₂ concentration of leaves increased more when the roots were insulated in both species. Hence, concurrent soil warming prevented metabolic damage to leaves during moderate heat-stress, suggesting that direct heat to the roots increased shoot thermotolerance. In both experiments, differences in air vs. air+soil heating effects on root respiration were directly related to differences in soil temperatures, such that root respiration was higher with air+soil heating. In neither experiment were soil temperature effects related to plant water status. These results suggest that both direct and indirect effects of soil warming may occur in woody species during a heat wave, but that the response may depend on the severity and duration of the heat-stress. Future research is needed to determine the underlying mechanism for differences between air vs. air+soil heating during a heat wave. Advisors/Committee Members: Heckathorn, Scott (Committee Chair).
