Previous observation demonstrated that measured nucleolar and nuclear diameters and the resulting calculated ratio might facilitate estimation of the approximate size of the nuclear region occupied by the nucleolar bodies. The size of nuclear regions occupied by nucleolar bodies decreased during the differentiation and maturation of leukaemic lymphocytes, but was constant for each differentiation or maturation stage. The present study was
unde-taken to provide more information on the approximate size of the nuclear regions occupied by nucleolar bodies in leukaemic granulocytic progenitors. Myeloblasts of established Kasumi 1 and K 562 cell lineages originating from human myeloid leukaemias were convenient models for such study because they represented only one and early differentiation stage of granulocytic progenitors. According to the results, the maximal and mean nucleolar body : maximal and mean nuclear diameter ratios in myeloblasts without heavy nuclear alterations were stable and not markedly influenced by the anti-leukaemic treatment or aging. Thus, the roughly estimated size of nuclear regions occupied by nucleolar bodies in these cells appeared to be similar and stable regardless of aging or antileukaemic treatment. In contrast, the antileukaemic treatment or aging in such myeloblasts induced marked reduction of the nucleolar biosynthetic activity reflected by the decreased number of nucleolar fibrillar centres. and Corresponding author: Karel Smetana
The article analyses a surgical treatment of 506 patients taking inpatient treatment in the Center for colon proctology. All the patients underwent a comprehensive examination including radiological and tool test methods in addition to conventional clinical and laboratory ones. On the basis of the complex study, indications, volume and terms of surgery performance were determined. Performance of preand postoperative management of patients is substantiated in details. Postoperatively, 28 (5.5%) had postoperative wound pyesis in the region of the previous colostomy. In the postoperative period 2 (0.4%) deaths of patients were caused with peritonitis which occurred due to incompetence of anastomosis sutures. Rehabilitation of stomed patients is one of challenges in colorectal surgery. Positive results treatment can be obtained only at carrying out of a comprehensive outpatient and inpatient preoperative preparation including recommendations in diet, colostome care, hydrogymnastics of the disconnected part of the intestine and prevention of infectious complications., Isakulov T.

We derive the phenomena of Landau damping as a stationary point of entropy functions with Lagrangian methods. The steady states are described inside of some interval of numbers with infinite fuzzy logic controllers. The results are also true for local equilibriums, i.e. for some global non-equilibriums functions.
Hypertrophied hearts are known for increased risk of arrhythmias and are linked with reduced ischemic tolerance. However, still little is known about state characterized only by increased left ventricle (LV) mass fraction. Seventeen isolated rabbit hearts with various LV mass were divided into two groups according to LV weight/heart weight ratio (LVW/HW ratio), namely group H and L (with higher and lower LVW/HW ratio, respectively) and underwent three short cycles of global ischemia and reperfusion. The differences in electrogram (heart rate, QRSmax, mean number, onset and dominant form of ventricular premature beats) and in biochemical markers of myocardial injury (creatine kinase, lactate dehydrogenase - LDH) and lipid peroxidation (4-hydroxy-2-nonenal - 4-HNE) were studied. As compared to group L, hearts in group H exhibited lower tolerance to ischemia expressed as higher incidence and severity of arrhythmias in the first ischemic period as well as increase of LDH and 4-HNE after the first reperfusion. In the third cycle of ischemia-reperfusion, the preconditioning effect was observed in both electrophysiological parameters and LDH release in group H. Our results showed consistent trends when comparing changes in electrograms and biochemical markers. Moreover, 4-HNE seems to be good potential parameter of moderate membrane alteration following ischemia-reperfusion injury., M. Hlaváčová, V. Olejníčková, M. Ronzhina, T. Stračina, O. Janoušek, M.
