The Most Famous Medical Tests of All Time
Medical history has seen a great number of innovations from time to time and it is the results of those medical tests that our life has become quite simpler and easy. Here, it is some of the most remarkable medical tests and their results which have to a greater extent have changed modern living and its pattern to survive.
Artificial Heart: Medical researcher Willem J. Kolff who was born in Netherlands invented the artificial heart and it was an American doctor Robert Jarvik who in 1982 completed the first design of permanently implantable artificial heart. The heart made by him can constantly beat at least 100,000 times a day pumping blood through the body.
Pencillin: it was discovered by bacteriologist Sir Alexander Fleming at London’s St. Mary’s Hospital in the year 1928. He witnessed during his test those colonies of bacterium Staphylococcus aureus being dissolved by blue-green mold. After further medical tests he found that a pure culture of mold has quality to kill diseases producing bacteria. He named that substance penicillin.
Pacemaker: It was the Canadian electrical engineer John Hopps who discovered the first pacemaker in 1950 though his pacemaker was quite large enough to be implanted inside the human body, however, its improved version was designed by New York medical researcher Wilson Greatbatch in the late 1950’s made it implantable and was powered by a corrosion-free lithium battery.
World’s First Test Tube Baby: Dr Patrick Steptoe , who was working on alternative way to conception in 1966 along with Dr. Robert Edward, a physiologist at Cambridge University found method to successfully fertilize and egg outside a woman’s body and performed in vitro fertilization procedure.
CPR: At the end of fifth decade, Dr. Peter Safar discovered cardiopulmonary resuscitation or CPR aligning with the development of ABCs (airway, breathing, circulation) of resuscitation, involving “mouth-to-mouth” resuscitation.
Oral Contraceptives: The first oral contraceptive, Enovid, was invented by Polish-born chemist Frank B. Colton in the ending years of late 1960s. This pill does not allow production of new eggs in a woman’s body thus prevents conception.
Genetic Engineering: Researchers Stanley Cohen and Herbert Boyer discovered DNA cloning technique letting genes to be transplanted on various biological spices. This has helped in developing synthetic insulin for people suffering from diabetes, a clot resolving agent for heart patients and growth hormone for underdeveloped kids are some of its products.
