Jonas Salk’s polio vaccine was part of the revolutionary devel- opments in pharmacological medicine of the 1950s and changed the face of childhood discount finasteride 5mg free shipping, both at home and abroad finasteride 1 mg discount. Other drug break- throughs of the era, such as steroids like cortisone and immuno- suppressants, made it possible for doctors to tackle illnesses of the immune system and opened up the possibilities for plastic and transplant surgeries. Open-heart surgery became common in the 1950s; another leap forward, organ transplants, began in 1967. By the beginning of the twenty- first century, thousands of heart transplant surgeries were being performed every year, and patients were living five years or longer with their donor hearts. The twentieth century was also a period of unprecedented tech- nological advances. The development of electron microscopes, endoscopes, computerized axial tomography (CAT), lasers, and other diagnostic tools radically transformed the practice of medi- cine. Discoveries in genetic and molecular biology, such as Francis Crick and James Watson’s cracking of the genetic code in 1953, also moved medicine in a new direction. In 1979 the world was declared free of smallpox, and in 1994 the United States was declared a polio-free zone. By the beginning of the twenty-first century, it was hard to imagine a time before mammograms became routine and before cancer could be treated with drugs, surgery, and chemotherapy. The Future of Medicine The monumental strides of the twentieth century helped to increase the human life span and fundamentally altered the way people look at health and illness. Where people once commonly died from polio, diphtheria, and smallpox, modern medicine now allows us to survive illnesses and accidents that would have been devastating in the past. The twenty-first century promises to be an era of even greater medical progress.
