In agreement with previous reports, we found that the bilirubin level is significantly lower in the blood of patients with coronary heart disease (CHD) than in age and sex matched controls. However, we found that the level of bilirubin in the blood seemed to be an age-dependent phenomenon and closely related to the activation of leukocytes. In 1,000 cardiac catheterised patients from Urbana, USA suffering from CHD, the level of blood bilirubin was found to be lower than in age and sex-matched controls. The same results were obtained on 300 patients with acute ischemia from three hospitals from Bucharest, Romania. The activation of polymorphonuclear leukocytes increased in the catheterised patients, as well in Romanian patients. An activation of leukocytes triggered by a chronic inflammatory process may increase the lysis of erythrocytes. The erythrocytes of patients with 100% stenosis exhibited a higher rate of in vitro lysis in the presence of activated leukocytes and homocysteine. The increased hemolysis may trigger the activation and removal of the resulting bilirubin from blood. Such a mechanism may depend on the liver clearing function. This function was decreased in catheterized patients over 60 years of age, but had accelerated in younger patients. An individual variation in liver function may explain the widespread bilirubin levels in the blood of patients suffering from CHD.

Dietary effects of trans fatty acids.

The dietary effects of the trans fatty acids in hydrogenated fats in health and disease deserves consideration for at least two reasons. One, trans fatty acids are becoming increasingly important as a source of calories in all industrialized countries, and two, their structural differences from the fatty acids in unhydrogenated fats offer a means of exploring uncharted areas in lipid metabolism. Such an exploration would have been impossible twenty years ago; some areas are still inaccessible because of a lack of methodology.
