The aim of this work is to study the features of the electrical and viscoelastic parameters of erythrocytes in patients with inflammatory bowel diseases (ulcerative colitis, Crohn’s disease, unclassified colitis), taking into account the stage of the disease for possible use in differential diagnosis.The electrical and viscoelastic parameters of erythrocytes were studied using dielectrophoresis in 109 patients with IBD, mean age 37,7 + 11,7 years (50 patients with ulcerative colitis (UC), 41 with Crohn’s disease (CD), 18 with unclassified colitis (UCC) and 53 conditionally healthy, comparable in age and sex with the main groups.Red blood cells of individuals with IBD differed from those in the comparison group by a smaller average diameter, an increased proportion of deformed, spherocytic cells with a changed surface character with a reduced ability to deform, a lower level of surface charge of cells, an altered membrane structure with an increased ability to conduct electric current, prone to destruction and the formation of aggregates (p <0,0001–0,05).Analysis in individual groups with IBD in the acute stage, taking into account the therapy, revealed significant differences between the forms of IBD: in patients with Crohn’s disease, in contrast to patients with UC, red blood cells had lower values of the amplitude of deformation, capacity, dipole moment, and velocity of movement of cells towards electrodes, the proportion of discocytes, polarizability at most of the frequencies of the electric field (p <0,00001–0,05). On the contrary, the summarized indicators of rigidity, viscosity, electrical conductivity, aggregation and destruction indices were higher in CD than in UC (p <0,0001–0,05). CD patients had a greater number of deformed cells with altered surface character (p <0,00001).The features of the electrical and viscoelastic parameters of erythrocytes in patients with differentnosological forms of IBD can be used for the differential diagnosis of ulcerative colitis and Crohn’s disease in case of colon lesions, in the long term — for verification of the diagnosis in unclassified colitis.

IntroductionHemoglobin crystals in the red blood cells were electronmicroscopically reported by Fawcett in the cat myocardium. In the human, Lessin revealed crystal-containing cells in the periphral blood of hemoglobin C disease patients. We found the hemoglobin crystals and its agglutination in the erythrocytes in the renal cortex of the human renal lithiasis, and these patients had no hematological abnormalities or other diseases out of the renal lithiasis. Hemoglobin crystals in the human erythrocytes were confirmed to be the first case in the kidney.Material and MethodsTen cases of the human renal biopsies were performed on the operations of the seven pyelolithotomies and three ureterolithotomies. The each specimens were primarily fixed in cacodylate buffered 3. 0% glutaraldehyde and post fixed in osmic acid, dehydrated in graded concentrations of ethanol, and then embedded in Epon 812. Ultrathin sections, cut on LKB microtome, were doubly stained with uranyl acetate and lead citrate.

Hemoglobin is the specific protein of red blood cells. Those cells in which hemoglobin synthesis is initiated are the earliest cells that can presently be considered to be committed to erythropoiesis. In order to identify such early cells electron microscopically, we have made use of the peroxidatic activity of hemoglobin by reacting the marrow of erythropoietically stimulated guinea pigs with diaminobenzidine (DAB). The reaction product appeared as a diffuse and amorphous electron opacity throughout the cytoplasm of reactive cells. The detection of small density increases of such a diffuse nature required an analytical method more sensitive and reliable than the visual examination of micrographs. A procedure was therefore devised for the evaluation of micrographs (negatives) with a densitometer (Weston Photographic Analyzer).

The protozoan parasite Entamoeba histolytica is the causative agent of amebiasis in man. The trophozoite or motile form is a highly dynamic and pleomorphic cell with a great capacity to destroy tissues. Moreover, the parasite has the singular ability to phagocytize a variety of different live or death cells. Phagocytosis of red blood cells by E. histolytica trophozoites is a complex phenomenon related with amebic pathogenicity and nutrition.

In human malaria, the most serious clinical manifestation is cerebral malaria (CM) due to infection with Plasmodium falciparum. The pathology of CM is thought to relate to the fact that red blood cells containing mature forms of the parasite (PRBC) cytoadhere or sequester to post capillary venules of various tissues including the brain. This in vivo phenomenon has been studied in vitro by examining the cytoadherence of PRBCs to various cell types and purified proteins. To date, three Ijiost receptor molecules have been identified; CD36, ICAM-1 and thrombospondin. The specific changes in the PRBC membrane which mediate cytoadherence are less well understood, but they include the sub-membranous deposition of electron-dense material resulting in surface deformations called knobs. Knobs were thought to be essential for cytoadherence, lput recent work has shown that certain knob-negative (K-) lines can cytoadhere. In the present study, we have used electron microscopy to re-examine the interactions between K+ PRBCs and both C32 amelanotic melanoma cells and human umbilical vein endothelial cells (HUVEC).We confirm previous data demonstrating that C32 cells possess numerous microvilli which adhere to the PRBC, mainly via the knobs (Fig. 1). In contrast, the HUVEC were relatively smooth and the PRBCs appeared partially flattened onto the cell surface (Fig. 2). Furthermore, many of the PRBCs exhibited an invagination of the limiting membrane in the attachment zone, often containing a cytoplasmic process from the endothelial cell (Fig. 2).
