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.] |
Some Last Minute Requests
A man woke up in a hospital bed and called for his doctor. He asked, "Give it to me straight. How long have I got?" The physician replied that he doubted that the man would survive the night.
The man then said, "Call for my lawyer." When the lawyer arrived, the man asked for his physician to stand on one side of the bed, while the lawyer stood on the other. The man then laid back and closed his eyes. When he remained silent for several minutes, the physician asked what he had in mind. The man replied "Jesus died with a thief on either side. I just thought I'd check out the same way."
