Pituitary hormoneIn 1937, the successful isolation of the first of the protein pituitary hormones was published in Science journal. Bovine prolactin (bPRL), the lactogenic hormone, was obtained in pure crystalline form by three doctors at the Yale University School of Medicine. This meticulous, time-consuming work by A. White, H.R. Catchpole and C.N.H. Long was done long before the availability of modern chromatographic methods of analysis and purification. The peanut-sized pituitary gland at the base of the brain is the master endocrine gland in vertebrate animals. Different pituitary hormones control the functioning of most of the body's endocrine glands, stimulate growth and control the water balance of the body. Prolactin was first named for its ability to promote milk production in response to the suckling stimulus of hungry young mammals.«[Ref: White, A., Catchpole, H.R. and Long, C.N.H., 'A crystalline protein with high lactogenic activity', Science (23 Jul 1937), 86, 82-83.]
A guy goes over to his friends house, rings the bell.
The wife answers the door.
"Hi, is Tony home?"
"No, he went to the store."
"Well, you mind if I wait?"
"No come in."
They sit down and the friend says, "You know Sara, you have the greatest breasts I have ever seen. I'd give you a hundred bucks if I could just see one."
Sara thinks about this for a second and figures what the hell - a hundred bucks. She opens her robe and shows one. He promptly thanks her and throws a 100 bucks on the table.
They sit there a while longer and Chris says, "They are so beautiful I've got to see the both of them. I'll give you another 100 bucks if I could just see the both of them together."
Sara thinks about this and says what the hell opens her robe and gives Chris a nice long look. Chris thanks her and throws another 100 bucks on the table then says he can't wait any longer for Tony and leaves.
A while later Tony arrives home and his wife says, "You know, your weird friend Chris came over."
Tony thinks about this for a second and says, "Well, did he drop off the 200 bucks he owes me?"
