Systemic iron deficiency was found in 63 (56%) of 113 joggers and competition runners (33 women and 80 men). Thirteen women and ten men had latent anemia. A majority of the women were fertile with iron loss from menstruation; the men were runners training long distances. The average transferrin iron-binding capacity was 80 mu mol/l serum in the women and 77(More)
The iron concentration in sweat and serum and related variables (transferrin saturation percentage, hemoglobin concentration) was measured in two groups of distance runners, each consisting of ten persons. In the first group unclear sweat was collected from the back of the athletes during cycling (without previous washing). The iron concentration (means +/-(More)
AIM To disclose the prevalence of adult "silent" coeliac disease in Denmark and Sweden. EXPERIMENTAL DESIGN 1573 Danish and 1866 Swedish healthy blood donors were screened for the presence of serum anti-gliadin antibodies (AGA) by enzyme-linked immunosorbent assay. AGA-positive serum samples were further analysed for IgA anti-endomysium antibodies (EmA)(More)
Development of quality manuals is a means for the promotion of quality in clinical laboratories by describing the total quality system. It also provides opportunity of checking whether the quality system is implemented in reality and demonstrates to the hospital administration and the clinicians that the laboratory is committed to quality. The intention of(More)
The purpose of this study was to evaluate the role of endogenous opiates in modulating physical performance during dynamic exercise in conscious man. The plasma concentration of beta-endorphin (BEP) and of adrenocorticotropic hormone (ACTH) along with muscle pain (McGuill Pain Questionnaire) were assessed in 17 trained, male runners before and after running(More)
The treatment of 10 patients having neoplastic disease with exogenous i.m. interferon therapy is described. The interferon given is partially purified interferon produced from human leukocytes. Sendai virus is used as interferon inductor. The patients reported in this paper have been on treatment for periods of 2-28 months. Apart from initial periods of(More)
6 long distance runners from the Danish marathon elite and 6 non-runners completed test runs of 28 and 12 km, respectively. Distance runners and non-runners showed the same responses in platelet function. We found a significant decrease in ADP induced platelet aggregability, a decreased serotonin release induced by ADP and collagen and an increase in(More)
Iron status was assessed by serum ferritin and haemoglobin in a population survey comprising 634 randomly selected urban Danes (312 males, 322 females) 14-23 yr old. At all ages, males had significantly higher serum ferritin and haemoglobin values than females. Males: median serum ferritin displayed a steady increase with age from 33 to 109 micrograms/l (rs(More)
Iron stores were assessed by measurement of serum ferritin in a population survey comprising 436 randomly selected urban Danish schoolchildren (219 boys, 217 girls) 7 to 17 years old. Median ferritin values were similar in boys and girls 7 to 13 years old, while 14- to 17-year-old boys had significantly higher values than girls of similar age (p < 0.0001).(More)
