...Russell L. Holman and a visitor were putting their heads together at Louisiana State University School of Medicine, pondering problems of heart-and-artery disease, when an assistant offered Holman a gory gift-an aorta, nearly 2 ft. long, full of diseased areas. It had been sent to Holman in a fine Macy's-tells-Gimbels gesture by his opposite number down the street, Dr. Charles E. Dunlap Jr. of Tulane University...
...aorta looked almost human. But Pathologist Holman knew that Pathologist Dunlap had been getting specimens from New Orleans' Audubon Park Zoo. Was it possible that here at last was an animal that developed atherosclerosis of the human type? The answer was yes. The aorta had come from a 16-year-old female baboon...
...baboon's aorta touched off a chain reaction of feverish activity, extending over 8,000 miles from Texas...
...where they were compressed into stillness long enough for a doctor to inject an anesthetic. Soon they were on the autopsy table where pathologists removed all vital organs for preservation and shipping to the U.S. Of 163 animals thus examined, about half were found to have atherosis in the aorta. Strangely, although the disease was commoner in the older apes, it was by no means confined to them. Many young ones had it. Also strangely, although atherosis of the coronary arteries is so common in humans, no evidence has been turned up to suggest that any baboon ever...
Physiologist Werthessen was doing experiments with baboons and their aortas to answer a host of questions about the effect of fats in the diet on the amount of fats (especially cholesterol) in the blood. In one especially tricky procedure he hooked up a baboon's freshly removed aorta with a heart-lung machine and used radioactive sodium acetate to find out how much fat is manufactured in the walls of the aorta itself. With a small branch baboonery at L.S.U., Dr. Holman was tackling related problems. Both hoped to get vital information with a direct bearing on human heart...
