There is mounting though far from conclusive evidence that 1) high amounts of cholesterol in the blood may increase the likelihood of heart attacks, and 2) the intake of unsaturated fatty acids, e.g., linoleic acid, derived mostly from vegetable oil, lowers the amount of cholesterol. With these facts in view, three pharmaceutical firms are rushing to market preparations containing such acids. All use safflower oil, which contains about 80% linoleic acid, is extracted from seeds of a thistlelike plant long grown in Africa, India, the Middle East. First marketers: San Francisco's Safflower Products Corp. (Saffola), North Chicago...

When other researchers showed that nicotinic acid or niacin (one of the B vitamins) was effective against an animal disease resembling pellagra, Dr. Spies seized on the clue, soon proved that simply adding niacin to the diet would go far to cure many cases. (It has since been shown that an amino acid, tryptophane, found in protein foods, is also essential in pellagra prevention.) But Experimenter Spies was convinced that where there was one vitamin deficiency, there were likely to be others. He advocated supplements of several vitamins, was sharply criticized for "shotgun" treatment, has been fully vindicated by later...
Magic Through Vitamins. Dr. Spies did much to prove the effectiveness of folic acid, another vitamin, in treating several forms of anemia, including early cases of pernicious anemia. Next, at the University of Havana's Calixto Garcia Hospital, he gave folic acid to victims of tropical sprue, a wasting, debilitating deficiency disease of which anemia is one symptom. Again, patients got better as though by magic. The burden of Spies's current work in Havana and San Juan: to defeat tropical sprue by prevention...
...weapon in their research is DNA (desoxyribonucleic acid), a complex chemical found in the nuclei of cells and believed to be concerned with heredity. From the Centre de Recherches sur les Macromollécules at Strasbourg, Professor Benoit and Father Leroy secured a supply of DNA extracted from the genitals of Khaki-Campbell ducks, which are smallish birds with brown bodies and greenish-black beaks. Then they bought from a reliable dealer nine new-hatched female ducklings and three males of the Pekin breed, which is larger and creamy white, with an orange bill...
