background: blood hemoglobin can be damaged by toxins such as lead. thus, this study was carried out to assess its blood hemoglobin concentration in the staff of kermanshah oil refinery that had been exposed to lead components. methods: in this study, 150 workers at kermanshah oil refinery were selected as the case group and 70 workers of textile industry factory were chosen as the control grou...

I N T R O D U C T I O N Gary-Bobo and Solomon (1) have proposed that the anomalous osmotic behavior of the erythrocyte is due to a decrease of the net charge of hemoglobin which occurs when the hemoglobin concentration inside the erythrocyte is raised. Employing Donnan equilibrium studies, they subsequently (2) produced evidence to show that a hemoglobin charge dependence on hemoglobin concentr...

OBJECTIVE To study the correlation between third-trimester serum ferritin concentration and hemoglobin and red cell indices to select the best hematologic characteristic to identify women who need iron therapy. METHODS In a prospective study, blood was drawn from pregnant women with hemoglobin above 10 g/dL, and thalassemia trait excluded at booking, at 28-30 weeks' gestation to study the cor...

CONTEXT Whether hemoglobin concentrations defined as anemia by the World Health Organization (WHO) are associated with increased mortality in older persons is not known. OBJECTIVE To investigate the association between hemoglobin concentration and cause-specific mortality in older persons. DESIGN Community-based study conducted from 1986 to 1996 (follow-up period, 10 years). SETTING Leide...

Introduction. It was reported that 25-hydroxyvitamin D level was independently associated with anemia in chronic kidney diseases, but the relation between vitamin D and anemia in diabetes mellitus is not still certain. We analyzed the relation between plasma 25-hydroxyvitamin D level and hemoglobin concentration. Materials and Methods. A cross-sectional study in male patients with type 2 diabet...

Previously, we reported that height is an indicator of the capacity of vascular repair in elderly men, especially hypertensive men. On the other hand, hemoglobin could act as a possible biochemical index of hypertension-induced vascular damage. However, no studies have clarified the correlation between height and hematopoietic activity. We conducted a cross-sectional study of 249 men aged 65-69...

We developed a ratiometric method capable of estimating total hemoglobin concentration from optically measured diffuse reflectance spectra. The three isosbestic wavelength ratio pairs that best correlated to total hemoglobin concentration independent of saturation and scattering were 545/390, 452/390, and 529/390 nm. These wavelength pairs were selected using forward Monte Carlo simulations whi...
