- Recent studies have indicated that diets rich in digestible carbohydrates and dietary fibre might be beneficial in the regulation of type II non insulin dependent diabetes (NIDD). Addition of the gel forming type of dietary fibre such as pectin and guar gum to meals or glucose solutions reduces post-prandial glucose and insulin response. Addition of cereal fibres in the form of bran seems to have long term beneficial effect improving glucose tolerance. Little is known, however, concerning effects of dietary fibre naturally occurring in food on postprandial glucose and hormone response. In the present study we prepared two breakfast meals which were similar regarding digestible carbohydrates but differed in their dietary fibre content. One of the meals, including whole grain bread and whole apples, contained 8.4 g of dietary fibre, and the other one, containing white bread and apple juice, 3.1 g. When given to eight NIDD, the fibre rich breakfast gave significantly lower blood glucose increment during the three hours following ingestion. The results indicate that foods rich in dietary fibre might be useful in the regulation of type II diabetes.

Serum ferritin in the regulation of iron therapy in blood donors
- 1980

- 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.

Accurate experimental lifetimes of excited levels in sodiumlike sulfur, S VI

- 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.

Plasma concentrations of platelet-specific proteins in young female acute myocardial infarction survivors and their age-matched female controls.

Tidskriftsartikel (refereegranskat)abstract
- The steady state plasma concentrations of the two platelet-specific proteins beta-thromboglobulin (BTG) and platelet factor 4 (PF4) were determined in two groups of females: 36 acute myocardial infarction (AMI) survivors, and 38 age-matched control subjects. For the AMI patients the mean BTG and PF4 values were 57 +/- 4 and 14.1 +/- 1.7 ng/ml, respectively. These two means significantly exceeded the corresponding means for the controls, 40 +/- 2 and 10.3 +/- 0.6 ng/ml, respectively. Similar results have recently been reported by other workers who investigated patients with coronary artery disease; however, in no previous study were the values for BTG and PF4 related to those obtained for control subjects matched with respect to sex and age. The present results therefore further support the concept that increased platelet activation and secretion is taking place in steady state patients who previously have sustained an AMI.

Morphometric study of mesenteric and renal arteries in spontaneously hypertensive rats
- 1983

Tidskriftsartikel (refereegranskat)abstract
- Arteries from spontaneously hypertensive rats (SHR), stroke-prone spontaneously hypertensive rats (SHRSP) and Wistar-Kyoto controls (WKY) were fixed by immersion and plastic embedded. The media cross-sectional area and the length of the internal elastic membrane were measured. The ratio between media thickness and internal radius was then calculated for a standardized condition, implying a perfectly smooth and circular internal elastic membrane. An increase of the media to radius ratio was already demonstrable in visceral arterial branches of SHR and SHRSP by 15 days of age, indicating that changes of arterial structure could be of pathogenetic importance in early hypertension. At seven months of age the ratio was significantly increased in mesenteric arterial branches of SHR and SHRSP and in renal arterial branches of SHRSP. The media to radius ratio was markedly increased in the renal and superior mesenteric arterial trunks of adult SHR (P less than 0.001 in both) and SHRSP (P less than 0.001 and P less than 0.01). This was due to a greater media cross-sectional area in the former vessels and to a combination of greater media and reduced radius in the latter.
