- 12 regular blood donors were selected on the basis of subnormal serum ferritin levels as a criterion for iron deficiency. It was found that all had high transferrin levels but only 5 had subnormal serum iron or transferrin saturation. The donors were given oral iron therapy in a dose of 2,800 mg between each phlebotomy, and the donation interval was standardized to 8 weeks. Test samples were collected every 4th week. After an initial rise in ferritin during the first 2 months, 6 of the donors again had subnormal serum ferritin levels, and the iron dose was therefore doubled after 32 weeks. Following this, all subjects taking the higher dose had normal ferritin values and stainable marrow iron was found at the end of the study, after 92 weeks. 3 subjects did not take the higher dose, had no raised serum ferritin level or stainable hemosiderin. It is concluded that serum ferritin estimation can be used to monitor the therapy in blood donors so that a satisfactory amount of iron is stored.

- The lifetimes of the terms 3p2P, 3d2D, 4s2S, 4p2P, 4d2D, 4f2F, 5g2G, 6g2G, 6h2H, 7h2H, 7i2I and 8k2K in sodiumlike sulfur, S VI, have been determined using the beam-foil excitation technique. Most of the decay curves were analyzed by means of the ANDC method which corrects for cascading in a very detailed way. Accurate results were thereby obtained which show that an excellent agreement exists between experimental and theoretical values. Some previously noted disagreements between the results of beam-foil experiments and theoretical investigations are explained as being due to less accurate analyses of the experimental data.
