Because of numerous limitations for liver biopsy, a noninvasive marker of liver cirrhosis is sought. Promising indicators seem to be matrix metalloproteinases (MMPs) that are responsible for degradation of extracellular matrix. The aim of the study was to evaluate the gelatinase activities (MMP-2 and MMP-9) in patients with different stages of alcoholic(More)
The present experiment was performed to assess if hypomagnesemia can influence antioxidant status in mice heart. The results could explain possibly a free radical theory of heart damage in magnesium deficiency. We used a rodent model of hypomagnesemia. The magnesium sufficient group received a standard diet whereas a magnesium deficient group received the(More)
This study was undertaken to evaluate the effect of chronic renal failure as well as dialysate sodium concentration during haemodialysis on membrane ATPase activity and erythrocyte sodium and potassium concentration. Intracellular Na and K were not changed in patients when compared to normal subjects. There was, however, a significant decrease of(More)
Enhanced sialylation of glycoproteins occurs during hypo- and hyperthyroidism. The role of sialic acid (SA) in cell membranes is well-standing, but its role in intracellular structures is still under analysis. We wanted to evaluate the influence of thyroid hormones on the sialylation ratio of intracellular proteins presented in cytosolic, mitochondrial,(More)
In cardial and femoral muscles of rabbits specific activities of aminoacyl-tRNA synthetases for twenty amino acids were generally similar, namely the activities towards amino acids and their amides, leucine, isoleucine, histidine, tyrosine, proline and serine were considerably lower than towards the remaining amino acids. Specific activities of most(More)
The aim of the present study was to estimate the concentration of Cu, Zn, Mg, Ca in the following tissues: brain, heart, lung, liver, kidney and femoral muscles in conditions of experimentally induced hyperthyreosis. In general, in state of hyperthyreosis the concentration of all elements was considerably higher compared to euthyreosis. However, there are a(More)
