| Rathke's pouch tumour | <oncology, tumour> A form of primary brain tumour which develops in the pituitary gland. These tumours often secrete increased quantities of pituitary hormones (for example growth hormone) which can result in conditions such as gigantism and acromegaly. They are often benign and rare and comprise less than 5% of childhood brain tumours. Other symptoms include vision changes, headache and weight gain. Treatment often includes a combination of surgery and radiation therapy. (27 Sep 1997) |

| pavlov pouch | at different points along the dogs' digestive tracts, the russian physiologist ivan petrovich pavlov (1848-1936) surgically created pockets ( pavlov pouches ) from which he could obtain secretions, the aim being to study the physiology of the digestive tract. He did so from the salivary glands down to the stomach, liver and pancreas with considerable success and in 1904 (the 4th year it was awarded) he received the nobel prise for his work on the physiology of digestion, through which knowledge on vital aspects of the subject has been transformed and enlarged.
