Scientists suggest that people who can stand more pain than others may be able to call forth extra supplies of enkephalins. Those with a low tolerance for pain may be deficient in either receptor sites or enkephalins...
...inserted into the DNA of E. coli bacteria which copies and decodes DNA rapidly. A ring of DNA--a plasmid--which is transferred between bacteria, is used for the incorporation procedure. It is easily isolated from a bacterial cell [1], cut open [2] and used as a receptor for a foreign gene [4]. The plasmid then carries the inserted DNA into a cell [5] where many copies can be "cloned...
Cimetidine owes its origin to the discovery that there are two types of receptor sites for histamine. The familiar site, associated with hay fever and other allergies, is in the nasal passages and nearby tissues. These conditions can be treated with a variety of widely prescribed antihistamines. But the drugs have no effect on the histamine receptors in the cells that secrete acid into the stomach...
...James Whyte Black of London's University College, a pharmacologist as well as physician, worked with chemists at Smith Kline & French Laboratories to find what are awkwardly called H2-receptor blockers. After testing over 700 compounds, they finally hit upon cimetidine. At present, their discovery has been approved for up to only eight-weeks' use by duodenal-ulcer patients and by victims of a few other diseases causing excessive acid secretion, like gastrinoma (tumors of the pancreas). Under the brand name Tagamet, the new drug should be available (on prescription only) by Labor Day. Cost of a four...
