Relationships between various types of chronic anemia, wound healing, and red cell 2,3-diphosphoglycerate (2,3 DPG) were examined in rabbits. Wound tensile strength and energy absorption were not affected by chronic iron-deficiency anemia, the chronic hemolytic anemia caused by intravenous water infusion nor by chronic hemolytic anemia caused by intravenous water infusion nor by chronic phenylhydrazine-induced anemia. Red cell 2,3 DPG levels were increased in the anemia of iron deficiency and were normal in the rabbits with chronic phenylhydrazine-induced anemia at the time of wound excision but were low following phynylhydrazine injection. The results show that chronic anemia per se does not affect the tensile strength and energy adsorption of wound healing. The findings suggest that the wound healing process may differ in certain types of anemia.

Serum iron deficiency has a high incidence in female athletes. We investigated the effects of a daily oral iron supplement, (160 mg) administered during an intensive 7-week physical training programme, on body iron status, and the maximal aerobic capacity (VO2max) of 13 women (group A) compared to 15 who took a placebo (group B). The subjects were 19 years old. Blood samples were obtained before training began and on days 1, 7, 21 and 42 of training. They were analysed for packed cell volume (PVC) and for haemoglobin (Hb), 2,3-diphosphoglycerate (2,3-DPG), haptoglobin, iron and ferritin concentrations. The VO2max was measured on days 0, 21 and 42 of training. Following 21 days of training Hb, PCV and ferritin were significantly higher (P less than or equal to 0.01) in group A compared to group B. Over the training period Hb rose by 9.3% and 2.4% in groups A and B, respectively. At the end of training 66% of group B exhibited ferritin concentrations below 10 ng.ml-1, while none of group A had such low values. Mean VO2max of group A had increased by 7.5% following 21 days of training (P less than or equal to 0.01) and by 15.3% after 42 days. No appreciable increase in VO2max had occurred in group B by day 21 (significantly lower than VO2max of group A; P less than or equal to 0.05), however by day 42 it had increased by 14.3% (P less than or equal to 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

18 components of metabolism were determined in the red cells of iron-deficient patients and data were expressed per 10(12) red cells to avoid the complicating effects of hypochromia and microcytosis. Glucose consumption, AMP and ATP, glycolytic intermediates except 2,3-bisphosphoglycerate (2,3-DPG) and phosphoenolpyruvate (PEP), red-cell Na+ and the net passive leakage of Na+ and K+ at 4 degrees C were all normal. Creatine, 6-phospho-D-gluconate: NADP oxidoreductase (6PGD) activity and fresh red-cell K+ were raised, suggestive of a young cell population. However, ATP: D-fructose-6-phosphate 1-phosphotransferase (PFK) activity and ADP were low. An elevated 2,3-DPG level was attributable to the anaemia present but the somewhat raised PEP level is unexplained. It is concluded that red cells in iron deficiency show some characteristics of a young cell population; in other respects they appear normal, but in containing a low PFK activity they are abnormal.
