The ability of lactose-intolerant individuals to tolerate 8 ounces of milk was determined in healthy teenagers. Thirty-two blacks were studied with 50-gm lactose tolerance tests. Nineteen (59%) had a flat blood sugar curve and 13 (39%) also developed bloating, cramps, loose stools, or diarrhea with the test. These latter 13 were defined as lactose-intolerant. Seven of the 13 lactose-intolerant teen-agers (54%) developed abdominal bloating and/or cramps after drinking 8 ounces of milk (half-pint). None had diarrhea. Eight were symptomatic with the equivalent amount of lactose (12 gm) while only one had symptoms with the monosaccharide components of lactose, glucose and galactose. The symptoms with milk and 12 gm of lactose were less severe than with the 50-gm tolerance test. A history of a prior awareness of milk intolerance was obtained from 11 of the 13 lactose-intolerant subjects. At least one haLf of lactose intolerant teen-agers might be expected to be symptomatic after drinking 8 ounces of milk without other food. Milk intolerance should be considered in the nutritional planning for teen-agers with special attention to members of population groups with a high prevalence of lactose intolerance.

1. A formula breakfast containing protein, carbohydrate and fat was given on two occasions to nine middle-aged male convalescent patients and to ten young men. The meals differed only in the type of carbohydrate given; sucrose or an isocalorific amount of glucose. 2. After the formula meal containing sucrose; (a) the alimentary lipaemia was cleared more slowly; (b) insulin response was smaller, and (c) there was a lower blood sugar curve than after the glucose meal. 3. The degree of lipaemia showed a significant positive correlation with insulin response which was, as expected, lower after sucrose than glucose. While attempting to confirm a report (Schilling, Hashim & Leonardy, 1964) that serum triglycerides are not significantly elevated after the ingestion of a small mixed meal, it was noticed that the triglyceride concentrations seemed to depend on the type of carbohydrate given (Mann & Truswell, 1971). Albrink, Fitzgerald & Mann (1958) and Sullivan (1960) have shown that the lipaemia which occurs after a fatty meal is diminished by the addition of glucose to the meal. Krut & Barsky (1964) found that postprandial lipaemia in patients with ischaemic heart disease is decreased by intravenous infusion of glucose and insulin. These considerations led us to examine the effects of glucose and sucrose and subsequent insulin release on alimentary lipaemia.

SUMMARY A study has been made of the inorganic serum phosphorus pattern in twenty-one acromegalic subjects during the 'augmented insulin tolerance test'. The serum phosphorus curve differed from normal in an elevated fasting level and, more especially, a reduction in the maximum fall. The latter anomaly is far more marked and constant than those found in the blood-sugar curve, and would thus seem to be a reliable criterion for the 'activity' of acromegaly.
