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)
20 male elite long distance runners were compared to a control group of blood donors to determine the effect of training on red blood cells. The acute effects of exercise on red cells were investigated in 11 of the runners following a race of 15–30 km. The runners had elevated resting values of red cell 2,3-DPG (P<0.05) and mean cell volume (P<0.01); blood(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)
Arterial blood pressure, total peripheral resistance (TPR), plasma catecholamine and other hormone concentrations were measured or estimated during, and 4 h following, a 20-min exercise test on the bicycle ergometer in 10 women with marginal (borderline) hypertension. Each woman served as her own control by repeating the whole procedure, except for the(More)
Abnormal myoglobinemia (above 77 Μg/1) and free hemoglobin in plasma were found in 16 runners and in nine non runners immediately following distance running. The same abnormalities were found in six elite rowers following rowing. In parallel with the rise in myoglobin and free hemoglobin a rise was found in serum concentrations of cellular enzymes (LDH, CK,(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)
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)
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)
