Maternal behavior during breast- and bottle-feeding.

Filmed records of an entire feeding session of a population of breast-and bottle-fed human infants were made at approximately 1-month intervals. The occurence of maternal and infant behavior is related to the infant's birth weight during the first week of life only in bottle-fed infants; the greater the mother's response, the less the small infant consumes. There are clear behavioral differences between bottle- and breast-feeding which stem from inherent characteristics of the technique of feeding. Breast-feeding allows the infant to have more control during the feed, whereas in the bottle-feeding, the mother has more control. This concept of control is discussed in terms of its implications for somatic growth and the development of obesity in relation to the advice and training of health professionals.

Effect of inheritance and stress on the diurnal excretion of sodium and potassium in young people with and without a family history of hypertension.

1. The diurnal excretion of sodium and potassium was observed in young people, with and without a genetic predisposition to hypertension, both in the presence and absence of psychological stress. 2. In the absence of stress, the normal day/night sodium excretion ratio was reversed in the children of hypertensive parents. This was significantly less than day/night sodium excretion in children of normotensive parents. A similar finding was observed for day/night potassium excretion. 3. There was a significant negative correlation between systolic blood pressure and day/night sodium excretion in children of hypertensive parents but not in children of normotensive parents. 4. After the mental stress of a University examination day/night sodium reverted to normal in children of hypertensive parents.

Effect of isometric exercise on the renal excretion of sodium and potassium in mild hypertension.

1. Basal levels of pulse rate, blood pressure and rates of sodium and potassium excretion were observed in eight white male patients with mild hypertension and eight age-, sex- and colour-matched controls during an initial rest period of 90 min and then for 5 h after a 1 h period of isometric exercise involving all four limbs in rotation. The studies were repeated on another day with the subjects resting instead of exercising for 1 h. 2. Changes in systolic pressure after exercise were similar in the hypertensive and control groups, whereas the rise in diastolic pressure was higher and the rise in pulse rate lower after exercise in the hypertensive group compared with the control group. 3. The changes in the rate of salt excretion were significantly different in the two groups, the hypertensive group retaining proportionately more sodium and potassium over several hours.

Two HLA-D and DR alleles are associated with coeliac disease.

A group of 45 children affected with Coeliac Disease (CD) was typed for HLA-A, B, C, D, and DR specificities. The most significant associations were found with two alleles of the D series, with both cellular and serological typing. It is suggested that the susceptibility to CD is determined by two different genes within the HLA region, the first in common with organ-specific autoimmune diseases and associated with DW3, the second possibly specific for CD and associated with Dw7.
