BACKGROUND/AIMS The pathogenesis of pancreatic fibrosis is unknown. Pathogenic analyses take into account the effect of oxidant stress and the increase in free radicals leading to degranulation of mast cells, which may cause inflammation and activate fibrosis. Activated pancreatic stellate cells produce abnormal components of intercellular substance and are… (More)
The aim of the experiment was to determine the effect of fluoride on ultrastructural changes in the submandibular gland, the pancreas and the liver. The experimental rats received fluoride in aqueous solutions of sodium fluoride at concentrations of 10.6 NaF/dm3 and 32.0 NaF/dm3. In the ultrastructural examination, mitochondria were most damaged.
The aim of the paper is to make an ultrastructural analysis of the nuclei of the pancreatic acinar cells in the rat in the course of lead acetate intoxication. The experiment used 84 Wistar rats, divided into 3 experimental groups, and a control group. The experimental rats were given aqueous solution of lead acetate in a dose of 50 mg/dm3 in group I, 500… (More)
The aim of the study was to evaluate alterations in exocrine cell mitochondria of the rat pancreas after lead acetate intoxication. The experiment used 45 rats divided into 2 experimental groups receiving lead acetate to drink, of lead concentration 50 and 500 mg/dm3 (ppm), and a control group given tap water. The animals from the experimental group were… (More)
IgA nephropathy is one of the most common forms of glomerulonephritis, but the coexistence of IgA nephropathy and psoriasis is very rare, especially in children. Herein we report the case of an 8-year-old girl with both psoriasis and IgA nephropathy who responded to treatment with cyclosporine A for both conditions.
The anthracyclines are among the most active and useful anticancer agents, but they are also the most common chemotherapeutics associated with the development of congestive heart failure. Twenty seven to sixty percent of patients with anthracycline-induced cardiomyopathy die of congestive cardiac failure. The paper presents the pathomechanisms of… (More)
Thorough understanding of magnetic nanoparticle (MNP) properties is essential for developing new theranostics. In this study, we provide evidence that non-modified magnetic iron oxide nanoparticles and their functionalized derivatives may be used to restrict growth and capture different pathogens. Coprecipitation of Fe(2+) and Fe(3+) ions in an alkaline… (More)
PURPOSE The aim of the present study was to examine the effect of freeze dried ethanolic extract of propolis (EEP), chrysin and caffeic acid phenethyl ester (CAPE) dependently on their concentrations on the viability and morphology of human astroglia cells line (SVGp12). MATERIAL AND METHODS Using gas chromatography - mass spectroscopy (GC-MS) we have… (More)
The purpose of this study was to evaluate the ultrastructural changes in the parotid gland of rats exposed to lead. The animals were given lead acetate in drinking water, at a concentration of 50 mg/dm3 Pb for periods of 2, 4 and 6 weeks. The ultrastructural examination showed that lead especially impaired mitochondria, caused accumulation of lipid droplets… (More)
A morphometrical analysis of changes in the heart of rats with experimental lung emphysema due to single intratracheal administration of papain solution has been done. Special attention has been paid to quantitative changes of capillaries and to the cardiomyocyte diameter in respective regions of the myocardium after one, three and six months following the… (More)
