peptic ulcer

If I am still alive today, I owe a thanks to an extraordinary scientist who continued to stand up for his opinion despite being alienated and ridiculed by his peers. Peptic ulcer used to be thought of as a complicated psychosomatic disease that is caused by certain types of life styles and high levels of stress. When Barry Marshall claimed that ulcer was in fact just a bacterial disease, no scientist in his right mind could believe him. After all, how could any bacteria survive in the highly acidic environment of the stomach? In order to prove his theory beyond any doubt, this courageous man drank a beaker of helicobacter pylori culture and fell violently ill. He subsequently cured himself using antibiotics, and later was awarded a Nobel Price for his discovery that saved millions of people from extreme discomfort and death.
