umbilical cord blood (ucb) has been used for transplantation in the treatment of hematologic disorders as a source of hematopoietic stem cells (hscs). because of insufficient number of cord blood cd34+ cells, the expansion of these cells seems to be important for clinical application. mesenchymal stromal cells (mscs), playing an important role in hscs maintenance, were used as feeder layer. apo...

objectives the aim of this study was to evaluate the biological effects of opium on the number of peripheral blood cells and red blood cells (rbcs) indices in diabetic rats. materials and methods peripheral blood samples were collected from diabetic, opium-addicted, diabetic opium-addicted and normal male and female rats and hematological parameters were measured. results the mean number of whi...

abstract background phenyl ketonuria (pku) is a congenital metabolic disease. irreversible brain damage is the result of phenyl alanin accumulation, so its amount should be restricted in patients diet. in their diet, trace elements such as hem iron, folic acid, vitamin b12 and, etc are also limited, and could represent anemia. in this study, the frequency of anemia in pku patients in yazd was i...

In this investigation, diabetes was induced in adult male Sprague-Dawley rats by single intraperitoneal injection of streptozotocin (STZ) at 45 mg kg-1 of body weight. A group comprised of 8 diabetic rats was treated with metformin at 100 mg kg-1 of body weight for reducing the elevated blood glucose level. The results revealed that, in the untreated diabetic rats, the body and testicular weigh...

the effects of dietary nucleotide (nt) on growth performance and some haematological parameters of striped catfish (pangasianodon hypophthalmus) were investigated. different levels of the nt (0, 0.25, 0.5, 0.75, 1%) in the diet were used for 10 weeks starting on the fish weighted (1.52 ± 0.11 g). the results showed that nt supplementations did not improve final weight, weight gain, food conserv...

changes of ions (na+, cr, k+), osmolarity and water concentration of body tissue, size and number of gill chloride cells as well as mortality percentage of the juveniles caspian roaches in weight groups of0.2, 0.5 & 1g water satiny stress were studied. the salinities tested  were 0 (fesh water), 7, 12.5 & 16g/lit and the assessments were completed 0, 12, 24, 48 & 72 hours after exposure. result...

stem cells are undifferentiated self regenerating multi potential cells. there are three types of stem cells categories by the ability to form after cells and correlated with the body’s development process. totipotent: these stem cells can form an entire organism such as fertilized egg. ploripotent: ploripotent cells are those that can form any cell in the body but cannot form an entire organis...

abstract evaluation of probiotic is not summarized on growth but included the other aspects, such as blood parameters. in this study, effects of two bifidobacter, bifidobacterium animalis and bifidobacterium lactis with three concentrations of 1× 109 (t1), 2× 109 (t2) and 3× 109 (t2) cfu/100g were studied on growth performance and hematological parameters of rainbow trout larvae with initial bo...
