ABSTRACT
The link-nurse scheme appears to be one way of narrowing the gap between theory and practice. This paper examines the concept, role, history and evolution of link nurses and, based on the author's personal experience of direct involvement in such a scheme, attempts to identify some of its advantages and drawbacks.

The effects of L-NG-nitro arginine (L-NOARG) on alpha-chymotrypsin-resistant, non-adrenergic, non-cholinergic (NANC) relaxations of guinea-pig tracheal smooth muscle have been examined. L-NOARG (1-100 microM), but not D-NOARG (100 microM), inhibited the NANC relaxations in a concentration-related manner. The effects of L-NOARG were partially reversed by L-arginine but not D-arginine. L-NOARG was without effect on acetylcholine-induced contractile responses of the trachea or on relaxations produced by vasoactive intestinal peptide, sodium nitroprusside or isoprenaline. These results suggest that an endogenous nitrate may contribute to NANC relaxations of tracheal smooth muscle.
