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.
