In verschiedenen Gebieten Saudi-Arabiens wurden anthropometrische Untersuchungen an 6- bis 19jährigen Schülern innerhalb einer Studie zur Bestimmung des Ernährungsstatus und der Ermittlung der Nährstoffzufuhr vorgenommen. Gemessen wurden Körpergewicht, Körperlänge, Hautfaltendicken an Bizeps, Trizeps, Subskapula und Abdomen sowie die Umfänge an Oberarm, Bauch und Wade. Mit Hilfe dieser Daten wurden dann Körperoberfläche, Grundumsatz und Körperzusammensetzung berechnet. Bei einer Gegenüberstellung dieser Ergebnisse mit Meßwerten aus Erhebungen in anderen Ländern zeigt sich, daß die Werte der saudi-arabischen Probanden weit unter denen vergleichbarer Altersgruppen aus den USA und Europa und unter denen aus arabischen Ländern und Indien mit Ausnahme von indischen Jungen aus armen sozio-ökonomischen Schichten liegen.A field study about the nutritional status was made in school classes with boys 6 to 19 years old in different regions of Saudi-Arabia. It is reported about 341 pupils in regard to weight, height, skinfold-thickness, circumferences and other body-size measurements. In comparison with anthropometric measurements of comparable surveys in other countries, the Saudi-Arabian school boys were found to be smaller and leaner than boys from the USA, Europe, other Arabian countries and well-to-do Indian boys.

Effect of authentic and natural vitamin C and carotene on amino acid absorption by F. A. El-Shobaki; Z. El-Hawary; N. Saleh; S. R. Morcos (12-17).
The effect of vitamin C or carotene either from authentic or natural sources on absorption of lysine, glycine and methionine was evaluated. Results revealed that maximum absorption of these amino acids was reached at different intervals from the orally given dose. Addition of ascorbic acid enhanced amino acid absorption and this effect was maximum in case of methionine. Carotene brought about variable effect to the three amino acids tested. Pepper, parsley, or orange juices did not affect the extent of intestinal lysine absorption. Pepper juice enhanced absorption of methionine in contrast to orange and parsley. Glycine absorption was markedly enhanced by addition of orange juice.Ascorbic acid suppelementation to dietary constituents is recommended for better utilization of proteins.

The effect of feeding an irradiated diet on the activities of some blood serum enzymes in rats have been studied. This study revealed some significant changes of SGOT due to sex differences. The results obtained failed to show any significant changes in the enzyme activities of SGPT and serum LDH neither in relation to sex nor to the irradiation doses studied.

Serum mineral changes in dithizone-induced diabetes before and after insulin treatment by D. Halim; K. Khalifa; R. Awadallah; Z. El-Hawary; E. A. El-Dessouky (22-26).
In this study, diabetes was induced by intravenous injection of dithizone. In dithizonised diabetic animals, the levels of serum zinc, iron, and potassium were found to be higher than normal, while those of serum calcium and sodium were lower. Copper and magnesium levels were unchanged.After treatment with insulin, most of these serum levels approached the normal, except for serum potassium and magnesium.

Protein and amino acid pattern in juvenile diabetes by Z. El-Hawary; M. F. S. El-Hawary; S. R. Morcos; M. K. Abdel-Khalek; R. Sakr (27-30).
A number of 21 diabetic juveniles and 20 controls comprised the material of this study. Serum total proteins and their electrophoretic separated fractions were estimated. Serum free amino acids were also investigated.Results showed that serum proteins were within normal range. An average increase of 49.5% in total free amino acids was reported. In general, the data for all the detected amino acids showed an average increase when compared with normal values. The significance of these findings in relation to the normal values were discussed.

Serum and urine amino acid pattern under the effect of carbon disulfide intoxication by E. A. El-Dessouky; M. F. S. Hawary; F. A. El-Shobaki; Z. El-Hawary; A. A. Massoud (31-38).
The effect of carbon disulphide intoxication on amino acid pattern was studied. Five groups of rats were treated with carbon disulphide through intramuscular injection of 0.05 ml CS2 in 0.2 ml olive oil/rat/day. A number of rats were sacrified after receiving 10, 20, 30, 40, and 50 injections.As a result of intoxication, a state of hypoaminoacidemia and hyperaminoacidurea affected all the amino acids investigated, but to variable extent.Of value to add that stoppage of carbon disulphide leads to improvement of the amino-acid pattern in group six, compared to the other groups.

Serum mineral changes in alloxan diabetes before and after treatment with some hypoglycemic drugs by D. Halim; K. Khalifa; R. Awadalah; E. A. El-Dessoukey; T. Hafez; Z. El-Hawary (39-43).
In alloxan diabetes, serum zinc, copper, iron and magnesium were significantly higher than in normal rats, while the level of serum calcium, sodium, and potassium was lower than normal. Treatment with daonil or insulin led to a normalization, as expected of the level of serum glucose and most of the other elements, except for iron and potassium. When lycanol was used for treatment, the level of all elements returned to the normal except for blood glucose, zinc and potassium.
