Hemoglobin (Hb) concentration, serum iron level, iron binding capacity and blood folate (Lactobacillus casei) activity were determined in 310 unselected pregnant Burmese women. Hb concentration was less than 11 g/dl in 72% of the women; the serum iron level was less than 50 mug/dl in 33%; serum folate activity was less than 3ng/ml in 13%; and red cell folate activity was less than 100 ng/ml in 17% of the women. Ninety-six of the women in our study were randomly divided into four groups, treated from the 22nd to the 25th week of pregnancy until full term with either ferrous sulfate containing 60 mg elemental iron twice daily, 5 mg folic acid twice daily, a combination of both, or a placebo only. At full term, Hb concentration fell in the groups given placebo or folic acid. On the other hand, in the groups given iron alone or iron plus folic acid there was an increase in Hb of 0.4 and 0.7 g/dl, respectively (intergroup difference not statistically significant). Serum iron and blood folate levels fell in the groups not receiving the appropriate hematinic. In spite of deficient serum and red cell folate levels in 30 and 40%, respectively, of the group on iron alone, the mean Hb concentration increased at full term and none of the women had a Hb concentration lower than 10 g/dl. Blood folate levels were lower in the iron-supplemented group than in the placebo group, indicating that iron deficiency does not aggravate the folate nutritional status.

Lateral X-ray pictures of the skull in certain several and chronic disorders of the blood as thalassaemia, congenital haemolytic anaemia, sickle cell anaemia and iron deficiency disease show frequently changes of the outlines of the cranial bones. They consist of a double contour of the outer cranial border and on the interior side below the sagittal sutura of a band-like shadow or of multiple stripes and lines running parallel to the carnial vault. They concern the parietal bones and may extend from the bregma till to the lamda or occupy only a part of this distance. The roentgenological features are due to the enlargement of the crainal bones, the bulging out of both parietal bondes, the sometimes enlarged and deepened borders of the sulcus sagittalis superior and particularly to the furrow and depression on the skull above the sagittal suture caused by the protruding parietal bones on both sides. As these different abnormal structures must be passed by the picturing X-ray, effects of superposition and interference are produced. Longitudinal ridges or bony edges which could explain the roentgenological findings could not be established. Since the peculiar alterations of the cranial bones are mainly found in the mentioned blood disorders, where they are caused by the overgrowing red marrow, they also display the same roentgenological features. These features are, therefore, a characteristic sign of these diseases.

In a random population of 198 pregnant women, detailed haematological determinations were performed at delivery. The prevalence of anaemia (haemoglobin less than 10 g/100 ml) is 20%. Iron deficiency is even more frequent. Malaria is shown to play an important role. Maternal anaemia is also correlated with nutritional status. Primiparae are shown to be at higher risk of anaemia. The effect of maternal anaemia on anthropometric and haematological variables of the newborn are discussed. Mothers with sickle-cell or HbC trait are not at special risk of anaemia.

The analysis of cord blood samples of 198 African newborns and their mothers confirmed the high prevalence of iron deficiency. A hypochromia and microcytosis of red cells was found in 40% of the pregnant women at term. In the majority of newborns the haemoglobin concentration was below 16 g/100 ml. Hb S was found in 11%, Hb C in 9% and alpha-thalassaemia in 2% of the population examined. Haemoglobin, packed cell volume and mean cell volume of erythrocytes were lower than results of newborns from developed countries. Foetal sex had no influence on haematological variables.

Causes of anaemia in 101 adult Melanesian patients admitted to Port Moresby General Hospital over a 3-year period with haemoglobin levels of 4.0 gms per 100 ml or less were studied retrospectively. Cases of anaemia due to acute haemmorrage were excluded. Iron deficiency was found in 80, haemolysis in 39, megloblastosis in 26 and anaemia of chronic diseases in 5 patients. Anaemia was secondary to multiple causes in 56 and to a single cause in 45 patients. In the group with multiple causes, a combination of iron deficiency and haemolysis was found in 28, iron deficiency and megaloblastosis in 18, iron deficiency, haemolysis and megaloblastosis in 6 and haemolysis and megaloblastosis in 5 patients. In the group with a single cause, iron deficiency was found in 34, anaemia of chronic diseases in 5, haemolysis in 4 and megaloblastosis in 2 patients. Hookworm infestation and malaria appeared to be the major underlying causes of anaemia in the majority of these patients. Three of 45 patients who had received blood transfusions shortly after admission to the hospital died, while there was only one death in the nontransfused group. It is concluded that: i) severe anaemia in Papua New Guinea is commonly secondary to multiple causes; ii) administration of iron and folic acid as well as treatment for malaria and hookworm is a responsible approach when these patients can not be investigated; and iii) blood transfusion does not appear to be necessary in this group of patients despite a very low haemoglobin level.

A family consisting of eight members in three generations (age 10 months to 53 years) affected with chronic mucocutaneous candidiasis was studied along with three unaffected relatives. Dermatophytosis, loss of teeth and recurrent viral infections were present in some members. Results of tests for endocrinologic, muscle or liver disease, thymoma, iron deficiency, antitissue antibodies and malabsorption were normal in all patients. Antibody function and levels, B cell counts, serum complement, leukocyte enzymes, chemotaxis, phagocytosis and adherence were normal in all members. Plasma inhibitors to lymphocyte transformation and leukocyte inhibitory factor were not found. No unique HLA haplotype or antigen segregated in this family. Evaluation of cell-mediated immunity revealed total cutaneous anergy in three of eight whereas four of the other five had negative lymphocyte transformation and skin tests to Candida but responded normally to other antigens. Leukocyte inhibitory factor was not produced to Candida antigen in all four patients tested. T cell counts were within normal limits in all. Extensive evaluation of all limbs of the immune system in this family revealed a defect in cell-mediated immunity to Candida that appeared to be inherited as a dominant characteristic.

A period of severe early iron deficiency (birth to 28 days of age) produced a persistent deficit (22%) in brain non-heme iron in adult rehabilitated animals. Long-term effects on behavior and physiological responsiveness were also observed. Although rehabilitated and control animals did not differ either in basal levels of plasma corticosterone or in the time course of the stress response following ether and cardiac puncture, possible differences in pituitary-adrenal responsiveness appeared to emerge following testing in an exploratory task. In addition, significant differences between rehabilitated and control animals were observed in both active and passive avoidance learning. Rehabilitated males made more intertrial responses than control males during active avoidance learning, and rehabilitated animals of both sexes performed better (i.e. showed longer reentry latencies) in a passive avoidance situation. It was suggested that shock may differentially affect motivation or arousal in rehabilitated and control animals.

Serum and red cell folate and folic acid binding protein (FABP) concentrations were determined on 20 iron deficiency anaemic children of both sexes aged 6--12 years. All cases had haemoglobin level less than 12 gm% or haematocrit less than 36% with low serum iron and elevated unsaturated iron binding capacity. Serum folate levels in the anaemic group was not significantly different from that of normal subjects while red cell folate level was significantly lower in the anaemic group. However, all cases had red cell folate levels higher than 100 ng/ml. There was a direct relationship between the haemoglobin concentration and serum folate level. Serum FABP level in the anaemic group was found to be significantly higher than that of normal subjects and showed no correlation with haemoglobin, haematocrit, serum or red cell folate levels. The significance of elevated serum FABP was discussed.

1. A standardized decompensation and recompensation of iron homeostasis has been produced by a change-over from normal to iron deficiency and back. 2. Under these conditions the 59Fe uptake into transferrin and ferritin of the mucosal "cytosol" and SDS treated "membrane" fraction has been measured together with the 59Fe amount transferred into the body. 3. The increase of the intestinal 59Fe absorption due to a progressive iron deficiency is associated with an increase of the 59Fe uptake into the mucosal transferrin of the "cytosol" and the "membrane" fraction; the reverse is observed with regard to mucosal ferritin. 4. Three days after the re-establishment of normal conditions the 59Fe absorption was lowered to normal values, while the 59Fe uptake into mucosal ferritin achieved again normally high values. 5. The high apparent rate of absorption in iron deficient animals decreased during the last 50 min after injection of the 59Fe labelled test dose. The 59Fe content in the ferritin fraction increased simultaneously, whereas the 59Fe content in the transferrin fraction remained the same. 6. The conclusion is drawn that the intestinal iron absorption is regulated by both mucosal iron binding proteins. Mucosal transferrin is responsible for the increase of absorption in iron deficiency while mucosal ferritin is responsible for the inhibition of iron absorption when the iron homeostasis recompensats.

Haemoglobin content and surface area of human red cells were estimated using a scanning cytophotometer connected to a computer for registration and analysis of the data. The measurements were carried out on fixed, unstained peripheral blood smears at a wavelength of 414 nm. The scanning can be controlled on the screen in order to detect errors and to eliminate extinctions from other sources than the cell examined. The method allows to demonstrate the topographic quantitative distribution of haemoglobin within the cell, to estimate haemoglobin content and surface area in individual cells and to correlate these values, to establish frequency distributions of the data within cell populations and to calculate various statistical parameters. Results of measurements on normal and abnormal red cells (iron deficiency, haemolytic anaemias) are demonstrated. The method may be used for investigation on red cell pathophysiology and may serve as a basis for image analysis in blood smears. It is too time consuming for direct diagnostic application in clinical practice.
