An experimental study was done to evaluate factors influencing guided regeneration of bone in standardized calvarial bony defect. An 8 mm circular transosseous calvarial bony defect was made. Various material such as demineralized freeze-dried bone (DFDB), BioMesh , Millipore filter and its combination was placed in the bony defect. A sequential histopathologic, histochemical, immunohistochemical, and histomorphometric studies were done on the guided bone regeneration in the calvarial bony defect. Bone formation was sigificantly enhanced when the DFDB was retained within the bony defect with a protective bioabsorbable membrane. Inframembranous DFDB-filling was required to prevent collapse of the membrane and preserve spaces for bone regeneration. The bioabsorbable membrane should presumably remain intact for longer than at least 5 weeks to facilitate bone regeneration. The new bone formation was dependent on the barrier-effect (preserving secluded spaces) and inflammation-inducing property of membrane, and guiding bone regeneration of the grafts. Macrophages recruited by grafts were partly involved in decrease of bone regeneration via the sequential events of release of fibronectin, chemotactic effect of the fibronectin to fibroblasts, and collagen lay-down.

Sixteen strains of LT-producing enterotoxigenic E. coli 0128 which were isolated from diarrheal patient's stool in Pusan University Hospital, were serotyped and analyzed for plasmid DNA profile, MRHA of human blood cells, and also tested for possession of LT, ST, aggA, EAST1 genes by the PCR method and analyzed the RAPD pattern. Screening sensitivity for ETEC by salting out test was 87.5%. These data suggest that hydrophobicity test using salting out is rapid, inexpensive, and simple screening test for ETEC. CFAs were identified in 87.5% of strains; 43.75% the strains harbored CFA/I, 43.75% CFA/II, and 12.5% expressed none of these CFAs. For plasmid profiles, 12 strains had 60 MDa plasmid and several smaller plasmids. The strains showed 5 types of plasmid profiles. By PCR, LT gene but not ST gene was detected from all of the 16 strains EAST1 gene was detected from 14 strains. Ten strains could be differentiated to 3 patterns by chromosomal DNA fingerprint. The chromosomal DNA fingerprinting is considered very useful for the epidemiological study.

The purpose of the study was to identify the nursing diagnoses for aged persons in gerontological clinical practice of nursing students. In this study, a total of 101 cases including 36 cases of hospitalized elder, 33 cases of institutionalized elders, and 32 cases of community dwelling elders were used in case studies reported by nursing students. Descriptive statistics was employed to determine 370 nursing diagnoses in 101 cases. There were four findings. First, 47.5% of total 370 nursing diagnoses was 'risk for injury'. The next highest percentage of nursing diagnoses was 38.9%( powerless/hopelessness/self-esteem disturbance). Second, the most nursing diagnosis for hospitalized elders was 'knowledge deficit'(41.7%), and the next was 'risk for injury'(38.9%), and 'risk for impaired skin integrity'(27.8%). Third, for both institutionalized elders and community dwelling elders, the most nursing diagnosis was 'risk for injury', and the next was 'powerlessness/hopelessness/self-esteem disturbance', and 'activity intolerance/impaired physical immobility'. Fourth, the related factors of 'risk for injury' were low bone density, low balance, low visual and auditory ability, muscle atrophy, low cognitive function, danger environment, and knowledge deficit. the related factors of 'powerlessness/hopelessness/self-esteem disturbance' were low activity ability, social isolation, low motivation depression, change of daily pattern, decrease of memory, and disorientation. These findings have implications that risk for injury related to physical changes of aging is the most significant health problem of frail elders in diverse setting. In addition, emotional problems of powerless, hopelessness, and self-esteem disturbance are significant need to develop nursing intervention for frail elders in diverse setting.

BACKGROUND: Ureteral stone(UTS) and acute pyelonephritis are the most common causes of nontraumatic acute flank pain in adults. Urography(IVU) is known as the most ideal diagnostic modality of obstructive uropathy to date. However, it has many practical limitations in overcrowding Korean emergency department to perform IVU as the diagnostic test of UTS. So we have performed prospective analytic study to compare IVU with its alternative diagnostic modalities. METHOD AND RESULTS: Our study was performed at Asan Medical Center from March, 1998 to July, 1999. We performed urinalysis, KUB, grayscale ultrasonography, and IVU in 243 patients, suspected to have UTS, based on histories, physical examination. After excluding patients with undetermined results(n=7) or spontaneous passage of stone before IVU(n=24), 212 patients were enrolled in our study. All of the other diagnostic tests were performed within one hour after emergency room presentation except IVU (53+/-24 hours). Diagnostic agreement among tests are as follows: Urinalysis shows good agreements with KUB(0.53) and IVU(0.62). KUB shows good agreement with IVU(0.48). Ultrasonography shows good agreement with IVU(0.58). Sensitivity(%), specificity(%), positive predicitive value(%), negative predicitive value(%), accuracy(%), and odds ratio of each diagnostic methods are as follows: Urinalysis is 91, 19, 78, 42, 74, 3.88; KUB is 55, 33, 72, 19, 50, 2.49; ultrasonography is 58, 92, 96, 41, 66, 45.61, and IVU is 81, 96, 98, 62, 84, 107.72. CONCLUSION: Although IVU seems to be the most ideal diagnostic modality for the UTS to date, it takes too long time for emergency physicians to confirm the diagnostic using IVU. We can performed other diagnostic modalities within one hour. However, emergency physicians suffer from poor diagnostic accuracy. Therefore, it is concluded that we are in need of more accurate alternative diagnostic modalities for UTS.
