摘要:

SummaryIt was shown that the total lipids, total and free cholesterol as well as the phospholipids of serum from umbilical cord blood are much lower than in normal adults.The investigation of lipoproteins in serum from umbilical cord blood showed that the α‐lipoproteins represented about 43 per cent and the β‐lipoproteins about 33 per cent. This ratio is likewise different from that found in normal adults, where the corresponding figures are about 30 per cent and 50 per cent.During the first 12 hours of life the total lipids, total cholesterol and phospholipids increase by about 10–15 per cent. This increase does not vary with the time between birth and collection of the sample. It is suggested that this increase might be due to a dehydration of the blood during the first postnatal hours, during which no changes occur in the lipoprotein distribution.During the first few days all the serum lipids increased steadily. Supplementary diet during the first day of life did not appear to accelerate the increase in serum lipids.During the first few days of life the increase of the serum lipids was accompanied by a marked change in the ratio between the α‐ and β‐lipoproteins. Thus on the fourth day the α‐lipoproteins represented 29 per cent and the β‐lipoproteins 46 per cent of the total lipids, a ratio corresponding roughly to that found in normal adults. Quantitatively, however, all the lipoproteins showed an absolute increase during that time. The most marked increase was that of the β‐lipoproteins which was more than 100 per cent.It was shown that the ratio of the combined to free cholesterol, which in the adults varied within narrow limits (2.3–3.1), is much lower (1.3–2.3) in umbilical cord blood. During the first few days of life both the combined and the free cholesterol increase in absolute amount, but with no change of the ratio between them.The cholesterol‐phospholipid quotient, which is about 0.90 in adults is about 0.60 in umbilical cord blood and increases to about 0.65 during the first few days of life.None of the data studied appeared to vary with sex or body weight at birth.The values found for children delivered by Caesarian section were not found to differ from the values found for children d

摘要:

Summary and ConclusionsAn attempt is made to see whether there are any differences in the distribution of hypertrophie pyloric stenosis in the various communities of the Jewish population in Israel, 264 cases being studied. It was found that the general incidence of this disease is very low, being 0.05 % of cases proved by operation or autopsy, and 0.06 % when including the clinically diagnosed ones.The distribution of hypertrophic pyloric stenosis is similar in the different communities. Since they come from three different continents, it would seem that there is no climatic influence on the etiology of this disease. It would be interesting to do a study in another country with a Jewish population in order to compare the incidence of this disease among these Jews and the general population, and thereby determine whether the low incidence found by us is due to ethnographic reasons.Fréquence de la sténose hypertrophique du pylore chez les différentes communautés juives d'Israël.L'auteur a tenté de voir, par l'étude de 264 cas, s'il y avait quelques différences dans la distribution de la sténose hypertrophique du pylore dans les différentes communautés de la population juive en Israël. Il a trouvé que la fréquence générale de la maladie était très basse: 0,055 % des cas vérifiés à l'opération ou à l'autopsie, et 0,06 % en y incluant les cas dont on a fait le diagnostic par la clinique. La répartition des cas de sténose hypertrophique du pylore est la même dans les différentes communautés. Puisqu'ils sont venus de trois continents différents, il semblerait que le climat n'a pas d'influence sur l'étiologie de la maladie.Die Häufigkeit der hypertrophischen Pylorusstenose in den verschiedenen jüdischen Gemeinschaften in Israel.Es wird der Versuch gemacht, festzustellen, ob irgendein Unterschied in der Verteilung der hypertrophischen Pylorusstenose in den verschiedenen Gemeinschaften der jüdischen Bevölkerung in Israel besteht. 264 Fälle wurden untersucht. Man fand, dass die Anzahl der Fälle sehr gering ist und nur 0,055 % bei den durch Operation oder Obduktion bestätigten Fällen beträgt, und 0,06 % wenn man die klinisch diagnostizierten mitrechnet. Die Verteilung der Pylorusstenose ist gleich in den verschiedenen Gemeinschaften. Da sie aus verschiedenen Kontinenten kommen, scheint es, dass klimatische Einflüsse für die Ätiologie keine Rolle spielen.La distribución de estenosis pilórica hypertrófica en diversas comunidades judías en Israel.Se hizo una tentativa para ver si hay alguna diferencia en la distribución de estenosis pilórica hipertrófica en diversas comunidades de población judía en Israel.

摘要:

SummaryThe successive analysis of specimens from the same infants during the first year of life showed that the values for serum lipids and lipoproteins vary widely. The spread of serial individual values was, however, not so great as for the group of infants as a whole.The serum lipids and lipoproteins showed a tendency to increase towards the end of the first year.The ratio between combined and free cholesterol also showed an increase towards the end of the first year.The ratio between cholesterol and phospholipids was found to be lower for infants than for adults.Analysis of individual variations in cholesterol fractions showed the ratio of combined to free cholesterol to increase with total cholesterol. With increasing total lipids the proportion of a‐lipopro‐teins decreased and that of β‐lipoproteins increased. However, all the lipoprotein components showed an absolute in
