introduction and aim: ip-10 molecule is a new biomarker to predict response to treatment in chronic hcv infection. also urine ip-10 has been suggested as a biomarker in other infections. but already, it has low data in urine as well as serum level of ip-10 for hcv infection. the aim of this study was to assess urine and serum level of ip-10 in patients with type 1 and 3a hcv infection. material...

serum ferritin (sf) levels in 734 seven-year-old children was measured by a radioimmuno assay method, and its possible relation-ship with hemoglobin, hematocrit and mchc was investigated. the results showed there was positive correlation between sf with hemo-globin, hematocrit and mchc values.

the immunosuppressive effect of antimacrophage serum (ams) on the primary immune response of mice to sheep red blood cells (srbc) was studied. ams, given before a small dose of antigen, abrogated the immune response. transplantation of normal, galss-adherent macrophages enabled ams-treated animals to respond to srbc, while administration of lymph node lymphocytes did not reveres ams - induced i...

migraine is one of the common varieties of headache. it involves 4 to 6 percent of men and 13 to 16 percent of women under 30 years in more than 80% of cases. some studies have shown that in 50% of patients serum magnesium level decreases during attacks of headache and using magnesium tablets and intravenous magnesium sulfate is more effective for treatment of migraine attack, than placebo. thi...

introduction and objective: zinc as the second trace element of the human body plays an important role in numerous functions. a large number of research studies have showed serum zinc deficiency and excess urinary excretion in patients with major beta thalassemia, but few studies revealed excess urinary zinc excretion in minor beta thalassemia and no study investigated serum zinc levels in this...

objective: the entry of toxoplasma gondii into the bloodstream and other tissues (such as liver, muscle, cardiac muscle, …) of intermediate hosts and its multiplication in nucleated cells may cause changes in plasma levels of various enzymes due to tissue damage. in present study the serum levels of ast, alt, alk/p, cpk, ldh, and acp in rats infected experimentally with toxoplasma gondii have b...

Background: No consensus has been reached on prognostic value of serum concentration of β (beta) subunit of human chorionic gonadotropin (β-hCG) in treatment response to methotrexate in management of ectopic pregnancy. Therefore, the present study aimed to evaluate this subject through a systematic review and meta-analysis. Materials and Methods: An extensive literature search on online databas...

Researchers add serum to a classical medium at concentrations of 5 to 10% (v/v) to grow cellsin-vitro culture media. Unfortunately, serum is a poorly defined culture medium componentas its composition can vary considerably while serum-free cell culture media are an excellentalternative to standard serum-containing media and offer several major advantages. Advantagesof us...
