Pituitary hormone

In 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 man placed some flowers on the grave of his dearly departed mother and started back toward his car when his attention was diverted to another man kneeling at a grave. The man seemed to be praying with profound intensity and kept repeating, "Why did you have to die? Why did you have to die?" The first man approached him and said, "Sir, I don't wish to interfere with your private grief, but this demonstration of pain is more than I've ever seen before. For whom do you mourn so deeply? A child? A parent?" The mourner took a moment to collect himself, then replied, "My wife's first husband."
