...into two main classes: blockages and aneurysms. Blockages may be almost anywhere-in the greatest vessel of all, the aorta, in the coronary arteries embedded in the heart wall itself, in arteries leading to the legs, and in the carotid and vertebral vessels carrying blood to the brain (see diagram, opposite page). The brain itself, however, is the province of the neurosurgeons...
...models of assistant ventricles have been produced steadily, in improved shapes and for both ventricles (see diagram, left). It is only seven weeks ago that the DeBakey team ran what it thought was a highly successful experiment with a unit that replaced both of a dog's ventricles. Yet progress in the field is so fast that within four days the researchers were dismissing their test as old hat. They were getting as good or better results with a single ballooning sac inserted in the left ventricle alone. It seems, says Dr. Hall, that this may be enough...
...PITUITARY GLAND. Just about the hardest part of the body for a surgeon to get at is the pea-sized pituitary gland (see diagram), producer of a few master hormones that govern the production of dozens of "slave" hormones. An overactive pituitary causes Cushing's syndrome, some forms of gigantism and adult overgrowth, and some cases of virilism in girls and women. Removal or deactivation of even a normally active pituitary helps some patients with advanced cancer of the breast or prostate, and diabetes victims going blind from bleeding of retinal arteries...
...tumor was growing, has remained virtually inviolate. Nerves, arteries and other vital parts of the anatomy are all crammed into that small central sanctuary behind the nose and mouth. There they rise through openings in the floor of the skull and reach toward the brain above (see diagram). So complex is the collection of vital mechanisms, it has defied generations of neurosurgeons, and the young man seemed doomed...
...broadcasts color signals simultaneously, combining them into a composite signal for transmission and separating them again in the receiver. The French "SECAM," which stands for Séquentiel à Mémoire (sequence and memory), transmits colors alternately and meshes them with a memory device in each set (see diagram). The system is made by Compagnie Francaise de Télévision, which is owned fifty-fifty by glassmaking Saint-Gobain and C.S.F., France's largest electronics manufacturer. Germany's "PAL" (for phase alternating line) system, made by Telefunken, is an embellishment of the U.S. version...
