there is evidence indicating that pomegranate juice contains many of the essential properties necessary to retain cell viability and cell proliferation. these properties indicate that pomegranate juice is a suitable storage medium for avulsed teeth. however, this idea has not yet been tested. in this study, the capacity of pomegranate juice (pj) as a storage medium for retaining avulsed teeth w...

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 vi...

The present study was conducted to investigate the effect of the diet containing Laurencia caspica (red algae) on blood parameters and digestive enzymes activity of goldfish after 90-day period. Goldfish (weight 6.10±0.1 gr) were divided to four experimental groups (30 individuals in each replication) including experimental treatment of the control group (without using red algae) and three trea...

the pharmacokinetics of recombinant human erythropoietin (rhuepo) administered intravenously has been investigated in a group of five patients with chronic renal failure who were dialysis-dependent. the half-life of circulating erythropoietin decreased from 7.9±oa hr (mean ±so) at the beginning of treatment to 6.2±o.6 hr after 6 weeks and 5a±o.9 hr after 4 months of treatment. in spite of the s...

The genetic locus designated Dpg has two alleles in outbred Long-Evans rats. Genotype at this locus affects quantities of red cell 2.3diphosphoglycerate (DPG) and adenosine triphosphate, as well as activities of two important glycolytic enzymes: phosphofructokinase and pyruvate kinase. Intravascular red cell survival is shortened in low-DPG animals. In order to get closer to the specific action...

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...

the decolorization of maxilon-red dye by kissiris immobilized phanerochaete chrysosporium in the trickle-bed reactor (tbr) using the basal nitrogen-limited growth medium was studied. the influence of the superficial liquid velocity (slv) on the decolorizing ability of the fungus was examined at four slvs (cm sec-1): 0.05, 0.075, 0.1, and 0.15. maximum level of the decolorizing activity was abou...

Glutathione reductase plays an important role in protecting hemoglobin, red cell enzymes, and biological cell membranes against oxidative damage by increasing the level of reduced glutathone (GSSGR) in the process of aerobic glycolysis. The enzyme deficiency may result in mild to moderately severe hemolytic anemia upon exposure to certain drugs or chemicals. However, hereditary deficiency of th...
