Background: Erythrocytes require an ability to deform and to withstand shear stress while negotiating the microcirculation. These properties are largely due to their excess surface area per volume and the characteristics of the membrane’s protein. Deficiencies of these proteins are associated with chronic haemolysis. Methods: This was a cross sectional  study aimed at determining the prevalenc...

this experiment was conducted to determine the effects of the oral consumption of guggulplant resin on the performance and humoral immunity response of broiler chicks. for doing this experiment, 320 one-day old chicks of the cobb 500 strains, in a completely randomized design with 4 treatments and 4 replicates were used. experimental diets include: control diet (without the guggul), control die...

background: blood is permanently exposed to oxidation stress and therefore has a high antioxidants capacity. many different factors increasing the demand for the antioxidant capacity can be observed in the stored blood of donors. consequently, damage to erythrocytes by free radicals may occur. so it is useful to control the alternation of anti-oxidant enzymes in stored blood at different days o...

this paper presents a 54-year-old female with lupus whom severe anaemia due to pure red cell aplasia (prca) was the first manifestation. there was seven years interval between prca onset and diagnosis of lupus. thymectomy due to thymoma had been carried out six years before but anaemia sustained. hypothyroidism and hypoparathyroidism were other associated diseases. severe anaemia and the need f...

conclusions while the crp value was in patients with acute brucellosis in the current study, the mpv, rdw and leukocyte counts were within the normal range. crp value remains the most valuable inflammatory marker in cases of acute brucellosis. results the follow-up within the year after treatment was examined. the values of age, gender, leukocyte count, c-reactive protein, rdw and mpv were reco...

background hemolyis of red blood cells is a serious toxic effect commonly found among patients envenomed by hemiscorpius lepturus scorpion. objectives the aim of the present study was to evlaute the efficay of the avaible polyvalent antivneom in preventing this phenomena. materials and methods using a red blood cell fragility test, the anti-hemolytic effectiveness of a new antivenom serum again...

This model focuses on the behavior of capillary-tissue fluid exchange system when the diameter of the capillary is less than that of red cell. In vivo and in vitro observations indicate that the width of the gap between the red cell and the vessel wall is generally small compared to the radius of the capillary for a single file flow of red cell in narrow vessel, particularly if the vessel diame...

The aim of this study was to compare invasive and non-invasive strains of Shigella flexneri isolated from Tehran by a 120 kDa protein band by SDS-PAGE, electron microscopy of cell culture and Congo red dye methods. Methods: S. flexneri strains were isolated by standard bacterial methods from fecal specimens of children attending to the 3 children’s hospitals. Phenotype analysis for screening v...

background: red blood cell and other blood products play a crucial role in management of different disease processes, but in spite of implementation of crucial steps to improve the process of request for blood and blood consumption, there is still not enough information available regarding the proper practice in many medical centres. we aimed to evaluate the status of blood product requests and...
