Pol Bouin
Pol André Bouin (11 June 1870 – 5 February 1962) was a French histologist and reproductive endocrinologist. He is best known for the fixative Bouin solution named after him. Bouin was born in Vendresse, France in a family of veterinarians. He studied medicine at Nancy and was influenced by Auguste Prenant. He received a doctor of medicine degree in 1897. He worked as a histology preparator and later became professor of anatomy in 1898. He succeeded Professor Prenant in the chair of histology at Nancy in 1908. He conducted numerous experiments. In 1929 he demonstrated that lactation could be induced in rabbits without ovaries by administering anterior pituitary extract at a time when prolactin Prolactin (PRL), also known as lactotropin, is a protein best known for its role in enabling mammals to produce milk.

Bouin Solution
Bouin solution, or Bouin's solution, is a compound fixative used in histology. It was invented by French biologist Pol Bouin and is composed of picric acid, acetic acid and formaldehyde in an aqueous solution. Bouin's fluid is especially useful for fixation of gastrointestinal tract biopsies because this fixative allows crisper and better nuclear staining than 10% neutral-buffered formalin. It is not a good fixative when tissue ultrastructure must be preserved for electron microscopy. However, it is a good fixative when tissue structure with a soft and delicate texture must be preserved. The acetic acid in this fixative lyses red blood cells and dissolves small iron and calcium deposits in tissue. A variant in which the acetic acid is replaced with formic acid can be used for both fixation of tissue and decalcification. The effects of the three chemicals in Bouin solution balance each other. Formalin causes cytoplasm to become basophilic but this effect is balanced by the effect o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Prolactin
Prolactin (PRL), also known as lactotropin, is a protein best known for its role in enabling mammals to produce milk. It is influential in over 300 separate processes in various vertebrates, including humans. Prolactin is secreted from the pituitary gland in response to eating, mating, estrogen treatment, ovulation and nursing. It is secreted heavily in pulses in between these events. Prolactin plays an essential role in metabolism, regulation of the immune system and pancreatic development. Discovered in non-human animals around 1930 by Oscar Riddle and confirmed in humans in 1970 by Henry Friesen, prolactin is a peptide hormone, encoded by the ''PRL'' gene. In mammals, prolactin is associated with milk production; in fish it is thought to be related to the control of water and salt balance. Prolactin also acts in a cytokine-like manner and as an important regulator of the immune system. It has important cell cycle-related functions as a growth-, differentiating- and anti ...
