Amino acids and lipoproteins in plasma of duodenopancreatectomized patients: effects of glucagon in physiological amounts.

Duodenopancreatectomy induces a severe glucagon deficiency and elevated plasma concentrations of alanine, aspartate, glycine, proline, serine, arginine, citrulline, ornithine, phenylalanine and tyrosine. Restoring high physiological plasma glucagon in six such patients by infusing 0.3 mg/24 h of exogenous glucagon reduced significantly (P less than 0.

Lipid, lipoprotein and APO-A and APO-B lipoprotein distribution in Italian and Swiss schoolchildren. The Geneva survey.

Cholesterol and triglyceride lipid, lipoprotein as well as apolipoprotein A and B levels, are presented for Italian and Swiss schoolchildren of similar socio-economic origin, living in Geneva, and ranging in age from 8-9 and 14-15 years. This cross-sectional study revealed some differences associated with the ethnic origin of the participants. Furthermore subtle changes were related to age, associated with puberty and were sex-specific.

[HDL and lipoproteins in the families of coronary patients].

Male first degree relatives of acute myocardial infarction patients differ from a control population by virtue of their low HDL cholesterol. The results are compared with those obtained previously in women and children who are first degree relatives of coronary patients. Low HDL cholesterol (Fig.

[High-density lipoproteins in children with coronary diseases].

Low HDL-cholesterol and increased LDL-cholesterol have been shown to be cardiovascular risk factors. Recently, HDL/serum cholesterol and HDL/ LDL-cholesterol ratios have been advocated as more reliable indices of cardiovascular risk factors. In a comparative study, lipoprotein-cholesterol and lipoproteins-triglycerides as well as the HDL/serum cholesterol and HDL/LDL-cholesterol ratios were determined in children of patients with coronary heart disease (CHD) and in healthy control children.

[Distribution of plasma cholesterol in 4 Swiss cities].

As part of the Swiss National Research Programme on Primary Prevention of Cardiovascular Diseases, plasma cholesterol was determined in 7947 adults of all ages. The distribution of the values obtained in the four Swiss cities investigated is given by age, sex and nationality. Percentile graphs of the whole sample show the influence of age for each sex.
