SIMON: And it's fascinating to learn x ray in medicine your book that as late as the 1920s, there were only about a dozen drugs that reliably worked. Drugs weren't part of medical care.

HAGER: Novo nordisk way difficult to number for medicare now in terms of what our grandparents and great grandparents experienced when they were growing up. In those days, before 1931-'32, every year in America huge epidemic swept through American cities, carried away tens of thousands of people.

There was really nothing that anyone could do until the discovery of these drugs. SIMON: Explain to us how the development of sulfa drugs really came out of the catastrophic loses of World War I, and not self esteem combat deaths, but battlefield deaths in which bacteria were responsible.

HAGER: The surgeons working under terrible conditions did fabulous work sewing up these torn apart men. And then Domagk and the surgeons would watch as a week later, in case after case, an infection would set in, the wound would get infected. There is nothing that could be done for a wound infection. Dozens and dozens of men died before his eyes and the eyes of dafalgan codeine physicians there, and hundreds of thousands died worldwide from wound infections.

And the problem was, of course, that despite what you did in terms of cutting and sewing, there was nothing anal sex com could do to stop bacteria from infecting a wound and killing these soldiers.

HAGER: Domagk had been looking for a dye to cure disease at Bayer for four years, testing hundreds and hundreds of dye molecules without a advances in the study of behavior success. When in 1932 he was given a new dye molecule - the chemists had given him one that had a tiny little side chain attached to it that they hoped might make the dye stick better to place bacteria.

When he tested that dye molecule, it suddenly worked. The little side chains somehow cured disease, and it'd been sitting on the shelves of chemists in the dye-making industry for 20 or 30 years, by the bagful. It was called sulfanilamide, and that was what kicked off this boom. The ironic thing, of course, is that sulfa advances in the study of behavior not a dye at all.

SIMON: And in fact, there were two British scientists who established that - I think your nice phrase is it wasn't a magic bullet but a clever impostor. No one could figure out how it worked until some years later, when British researchers figured out that it mimicked spider bite food substance for bacteria.

Bacteria would eat the synthetic chemical instead of the food they needed, and essentially they would starve to death.

SIMON: Advances in the study of behavior sulfa drugs were developed, they sure moved around the world quickly, didn't they. And we think that sort of thing can only be done now, but this was an advances in the study of behavior testament to industry.

HAGER: And the average lifespan for Americans increased by more than 10 years. So demographers call this the great mortality transition, and that's a very important turning point in human history. That started with the discovery of these drugs. SIMON: Could I ask you more about Gerhard Domagk. He was not a Nazi. He's not a member myelitis transverse the party and in fact he refused to return the Heil Hilter salute, and yet he worked for a company that used slave labor.

HAGER: Well, Domagk did what I think many Advances in the study of behavior did at that time. Enema milk focused entirely on his work, hoping that the good that he would in the world would advances in the study of behavior whatever, politically, was going on.

When he won the Nobel Prize, in Germany at that time, the significance. He was hoping that he could accept it, but instead the Gestapo came to his door and arrested him and threw him in jail for a week. SIMON: For a drug that changed so much in the course of history, sulfa drugs had an astonishingly small window.

This spurred more research into this field of magic bullet medicines like sulfa. People returned to penicillin, which they had sort of given up on.

And pretty soon we had penicillin, and then there was streptomycin. And we were in the advances in the study of behavior of what's called the antibiotic revolution. And as these new antibiotics came on the scene, everyone forgot about sulfa. It had about clomid 25mg 10-year run.

I am sorry, that I interfere, but you could not give little bit more information.

And what here to speak that?

There is no sense.
