β¦ Synopsis
From 108 healthy 13 years old school children who took part on a longitudinal study in regard to serum lipids and lipoproteins 64 with normal body weight were examined. Lipoproteins were estimated by means of preparative ultracentrifuge and polyanionprecipitation (Heparin and Manganese-chloride) according to the Lipid Research Clinics Methods, NIH~ Bethesda.
Mean values and S.D. were calculated as: Total cholesterol: 155 +29, 150 + 35 mg/dl; LDL-cholesterol 98 +21 and 96 + 34 mg/dl; HDL-cholesterol 44 + 13 and 44 + 13 mg/dl for males and females respectively. The few data from the literature showing wide variations in LDL-and HDL-cholesterol concentrations are compared with our results; methodological considerations indicate that for further epidemiological studies concerning the possible risk factors for premature atherosclerosis standaradized laboratory tests should be provided.

We set out to determine whether lung function of children with a birth weight of <1,501 g changed relative to expectations between the ages of 8 and 14 years. We hypothesized that changes in lung function may differ between those of birth weight above and below 1,000 g. The subjects of this study we
