RESUMEN
St. Mary's Hospital Medical Inspecting Center acquired ISO 15189 authorization in December, 2007. In the process of authorization acquisition, measures were taken to improve various quality issues, and a marked effect was seen in patient services and medical safety control. Furthermore, we tried to improve ward nursing management using ISO, drew up standard operating procedures through detailed job analysis, and enabled ward operation standardization. In this paper, while describing the effect of ISO 15189 on clinical examinations, we refer to the significance of improving quality of hospital management which our clinical laboratory lead to.

The spinach ( Spinacia oleracea L. (cv. Hoyo) nitrate reductase inactivator (NRI) is a novel protein that irreversibly inactivates NR. Using degenerate primers based on an N-terminal amino acid sequence of NRI purified from spinach leaves and a cDNA library, we isolated a full-length NRI cDNA from spinach that contains an open reading frame encoding 479 amino acid residues. This protein shares 67.4% and 51.1-68.3% amino acid sequence similarities with a nucleotide pyrophosphatase (EC 3.6.1.9) from rice and three types of the nucleotide pyrophosphatase-like protein from Arabidopsis thaliana, respectively. Immunoblot analysis revealed that NRI was constitutively expressed in suspension-cultured spinach cells; however, its expression level is quite low in 1-day-subcultured cells. Moreover, northern blot analysis indicated that this expression was regulated at the mRNA level. These results suggest that NRI functions in mature cells.
