| non-specific system | <physiology> A physiological term denoting that part of the brainstem reticular formation that plays a central role in the organism's bodily and behavorial alertness. It extends as a diffusely organised neural apparatus through the central region of the brainstem into the subthalamus and the intralaminar nuclei of the thalamus; by its ascending connections it affects the function of the cerebral cortex in the sense of behavioural responsiveness; its descending (reticulospinal) connections transmit its activating influence upon bodily posture and reflex mechanisms (e.g., muscle tonus), in part by way of the gamma motor neurons. See: reticular formation. Synonym: non-specific system. (05 Mar 2000) |

| non-steroidal anti-inflammatory | <pharmacology> A large group of anti-inflammatory agents that work by inhibiting the production of prostaglandins. They exert anti-inflammatory, analgesic and antipyretic actions. Examples include: ibuprofen, ketoprofen, piroxicam, naproxen, sulindac, aspirin, choline subsalicylate, diflunisal, fenoprofen, indomethacin, meclofenamate, salsalate, tolmetin and magnesium salicylate. A contrast is made with steroidal compounds (such as hydrocortisone or prednisone) exerting anti-inflammatory activity. Acronym: NSAID (05 May 2002) |

The only common feature among these tumours is the absence of giant reed-sternberg cells, a characteristic of hodgkin's disease. (12 Dec 1998) |
