The Old Lawyer
Joe the lawyer died suddenly, at the age of 45. He got to the gates of Heaven, and the angel standing there said, "We've been waiting a long time for you."
What do you mean he replied, "I'm only 45, in the prime of my life. Why did I have to die now?"
"45? You're not 45, you're 82" replied the angel.
"Wait a minute. If you think I'm 82 then you have the wrong guy. I'm only 45. I can show you my birth certificate."
"Hold on. Let me go check" said the angel and disappeared inside. After a few minutes the angel returned.
"Sorry, but by our records you *are* 82. I checked all the hours you have billed your clients, and you have to be 82..."

Sulfa drugsIn 1951, a patent for improved sulfonamide drugs was issued to James W. Clapp and Richard O. Roblin, (U.S. No. 2,554,816). Sulfa drugs are members of a group of synthetic antibacterial drugs containing the sulfanilamide molecular structure. Sulfonamides (first observed in 1932) were the first chemical substances that were systematically used to cure and prevent bacterial infections in humans. Of the 5,000 sulfa drugs prepared and tested, fewer than 20 continue to have therapeutic value because resistant strains of bacteria have developed. More potent antibacterial drugs have largely replaced the sulfa drugs. They remain useful in the treatment of urinary tract infection.[Image: The general formula of the patented drugs is a 5-membered heterocyclic sulfonamide having at least 3-hetero atoms. X is carbon or nitrogen which may have substituents such as hydroxyl, amino, acylamino or sulfonanide radicals; R and R' can be hydrogen, alkyl, alkaryl or aryl radicals; Y is sulfur or nitrogen (which in the case of nitrogen may have substituents such as an aryl or alkyl radical. Also X, Y may be part of a fused ring system in which the 5-membered ring shown forms a ring fused with a 6-membered heterocyclic ring such a pyridine.] |
