Introduction and Objectives: One of the characteristic changes of tumor formation is accumulation of genetic disorders in mitochondrial and nuclear genome. Mitochondrial disorders, from its side, are responsible for failure of metabolism, apoptosis, cell growth, formation of reactive oxygen species, etc. Overprpoduction of reactive oxygen species (ROS) significantly impacts the respiration chain enzymes and entirely the antioxidant system of mitochondria. Finally this may become a favorable condition for normal cells transformation. The purpose of the presented work was to study the mitochondrial defects and to establish their role in prostate cancer development. Results: Experimental results demonstrate significant increase of the activity of mitochondrial succinate dehydrogenaze (complex II) of the malignant epithelial cells of prostate, and slight changes in cytochrome oxydase (complex IV) activity. Also significant activation of the antioxidant system (glutathione-dependant system) of mitochondria in prostate malignant epithelial cells was revealed. Conclusion: The above mentioned mitochondrial changes (II and IV complexes of respiration chain, activity of the antioxidant system) partially demonstrate the alterations in mitochondrial energy metabolism, which from its side, may indicate to resistance of prostate cancer cells and correspondingly to intensification of proliferation processes., Nanuli Kotrikadze, Nanana Alibegashvili, Liana Ramishvili, Manana Gordeziani, Nato Veshapidze, Teimuraz Chigogidze, Laurent Managadze, and Literatura
Autoři ve svém sdělení prezentují novou, minimálně invazivní metodu léčby benigní hyperplazie prostaty. Jde o technologii „The RezūmTM System“ založenou na použití sterilní vodní páry, která je pod tlakem aplikována do prostatických laloků, kde působí ohraničené termické léze a výsledně potom zmenšení objemu prostatické tkáně s následným poklesem symptom skóre, objemu postmikčního rezidua a zvýšení maximálního průtoku Qmax. Součástí práce je i zhodnocení vlastních výsledků použití této léčby. Klíčová slova: benigní hyperplazie prostaty minimálně invazivní léčba aplikace sterilní páry Rezūm™ System, The authors present a new, minimally invasive treatment of benign prostatic hyperplasia. This is a technology of „The RezūmTM System“ based on the use of sterile water vapor, which is applied to the prostatic lobes under pressure. Sharply confined thermal lesions consequently lead to the reduction of prostatic tissue volume, which results in symptom score reduction, postvoiding residual volume reduction and increase of maximal flow Qmax. The article also includes evaluation of our results using this treatment. Key words: benign prostatic hyperplasiaminimally invasive treatment the application of sterile steam RezūmTM System, and Pacík D., Vít V., Varga G., Čermák A.
