Description:
Typickým patologicko-anatomickým rysem emfyzému je permanentní rozšíření dýchacích cest distálně od terminálních bronchiolů spolu s destrukcí plicního parenchymu, bez výraznější fibrózy. Chirurgická léčba nabízí tři typy intervencí: bulektomii (resekci velkých bul utlačujících zdravější část plíce), volumredukční operaci plic (LVRS) a plicní transplantaci (jedno či lépe oboustrannou). Alternativou LVRS u inoperabilních nemocných mohou být některé bronchoskopické techniky - metody bronchoskopické volumredukce (BVR). Cílem našeho sdělení je ukázat roli radiologa při indikaci bronchoskopické volumredukce., Lung emphysema is characterized as permanently enlarged air space distal to terminal bronchioles accompanied by destruction of lung parenchyma without fibrosis. There are three types of surgical treatment: bullectomy (resection of large emphysematic bulls which oppreses healthy lung parenchyma), volumreduction and lung transplantation (once or double - faced). When surgery is not possible there are some bronchoscopic techniques - bronchoscopic volumereduction. The aim of our list is to show the role of radiologist for the right indication to bronchoscopic volumereduction., Kočová E, Koblížek V, Rúta J, Bartoš V., and Literatura

Description:
Gastrointestinal form is the second stage of acute radiation syndrome (ARS) with a threshold dose of 8 Gy in man. It represents an absolutely lethal clinical-pathological unit, necro-hemorrhagic enteritis and proctocolitis, with unknown causal therapy. Elk-1 is a protein acting as a transcription factor activating specified genes. The purpose of our study was to examine the expression of phospho-Elk-1 in irradiated jejunum and transversal colon of rats with radiation-induced enterocolitis and to assess the importance of this transcriptional factor as a biodosimetric marker of radiation-induced enteropathy. The laboratory rats were randomly divided into 21 groups, 10 animals per group, and irradiated with whole body γ-irradiation of 1, 5, 10, 15, and 20 Gy. Samples of jejunum and transversal colon were taken 24, 48, 72, and 96 hours later, immunohisto-chemically stained, and the phospho-Elk-1 expression was examined using computer image analysis. A group of 10 sham-irradiated animals was used as control. Significantly increased expression of phospho-Elk-1 in rat jejunum has been found in all time intervals after irradiation by sublethal doses of 1 and 5 Gy, whereas after the irradiation by lethal doses, the expression of phospho-Elk-1 in rat jejunum varied considerably. Significantly increased expression of phospho-Elk-1 in transversal colon has also been found in the first days after irradiation by sublethal doses of 1 and 5 Gy. After irradiation by lethal doses, tere was no uniform pattern of the changes in the expression of phospho-Elk-1 in rat transversal colon. The detection of phospho-Elk-1 might be considered as a suitable and very sensitive biodosimetric marker of radiation-induced injury of small and large intestine. According to our knowledge, this is the first study on the phospho-Elk-1 expression in irradiated jejunum and transversal colon in the rat., D. Driák, J. Österreicher, Z. Řeháková, Z. Vilasová, J.
