Glycaemic control and reticulocyte count in diabetic patients.

Correlation coefficients between glycosylated haemoglobin, mean fasting glycaemia, and reticulocyte count have been assessed in 61 diabetic patients. When excluding those with overt anaemia and with serum iron below 12.5 mumol/l, the correlations became significant. Thus, reticulocyte count may be a useful indicator of glycaemic control (paralleling HbgAIc), provided anaemia and low serum iron are excluded.

[Dynamics of the composition of lipids in human milk during lactation]. / La dynamique de la composition des lipides du lait humain au cours de la lactation.

The authors have studied the total lipids, triglycerides and cholesterol in the milk of 30 mothers over a lactation period of 4 days to 10 months. The total lipids showed diurnal oscillations with a minimal level in the morning and maximal level (P less than 0.001) at 1 p.m. and a slight decrease in the evening, without reaching the levels found in the morning. The lipid concentration in the milk decreases after 4 months of lactation. The oscillations of the lipids take place on the expense of the triglyceride content (r = 0.99). Cholesterol represented on the average 1.54% of the lipid content, showed a maximum level at a month and decreased after 6 months of lactation. The dynamics of lipid composition of the human milk suggests a physiologic significance in the development of the infant.
