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.

testosterone level was determined in six different populations of iran using saliva steroid assay. significant difference was observed in morning and afternoon testosterone level of the same individual (p>0.00l) significant difference was also noticed among different regions studied (p>0.00 1). comparisons between alcoholics and nonalcoholic as well as smokers and nonsmokers showed significant ...

The effect of the administration of a synthetic peptide with corticotrophic properties (18-ACTH) on the plasma corticosteroid levels of 72 healthy volunteers was studied. The same effect is seen both after subcutaneous and intramuscular injection. Intravenous administration provokes a longer lasting influence on adrenocortical activity, especially when large doses of the peptide are given; side...

A highly sensitive enzyme-linked immunosorbent assay was used for the analysis of serum IgG reactivity against specific immunogenic Treponema pallidum proteins. Outer membrane treponemal proteins purified by preparative SDS-polyacrylamide gel electrophoresis were used as antigenic probes at concentrations as low as 100 ng per ml (5 ng per well in microtitre plates). Detection of anti-treponemal...
