The prognostic significance of morphologic parameters was evaluated in 36 cases of renal cell carcinoma diagnosed during five years(1986~1990). We reviewed and classified on the basis of pathologic stage, tumor size, histologic pattern, cell type and nuclear grade. Mean age was 51 years old. Average tumor size was 7.3 cm in diameter. Six of 35 patients died of disease. Overall mean survival was 43.3+/-7.3 months. An increasing nuclear grade was generally correlated with a decrease in cummlative survival rate. Similarly, a higher stage at the time of diagnosis could predicated a low survival rate only for high nuclear grade carcinoma. There was an apparent positive correlation between grade and age, grade and size, grade and cell type, cell type and histologic pattern as well as stage and age. This positive correlations are in part a function of nuclear grade; only 20% of grade 3 & 4 tumor consisted of clear cells whereass 71% of grade 1 & 2 consisted of clear cell type. All 6 cases of granular cell types and 50% of mixed cell type were grade 3 & 4. The tumor size of the primary was well correlated with the nuclear grade. Nuclear grade was the most significant factor among the morphologic parameters studied.

To investigate the mechanism of crescent formation, sequential pathologic changes from the New Zealand White rabbits with anti-GBM antibody induced GN by administration of guinea pig anti-GBM IgG were studied by light (LM), immunofluorescent (IF) and electron (EM) microscopy. Although no glomerular changes were observed in LM, swelling of the endothelial cells and the epithelial cells were noted in EM by day 2. By day 7, early and cellular crescents were evident. Proteinaceous materials and fibrins were noted in the glomerular capillary lumina (GCL) and Bowman's space (BS) associated with segmental hypercellularity. The GBM damage became progressively severe, followed by focal detachment of the visceral epithelial cells from the GBM. At day 14, fibrin strands, mononuclear cells and collagen fibrils were present between the proliferating extracapillary cells. At day 31, fibrocellular crescents were predominated. Elongated spindle cells, morphologically resembling myofibroblasts, were noted near the Bowman's capsule (BC). A degree of tubular atrophy, interstitial fibrosis, and inflammatory infiltrates increased as it did with fibrous organization of crescent. Intense linear IF staining for IgG and C3 were seen throughout the experiments along the GBM. In conclusion, the progression of crescent from an early "proteinaceous" stage through cellular, fibrocellular and fibrous stages was well documented in this study. Inflammatory cells and coagulation mechanism may activate the initiation of the GBM damage at the early stage. Activated periglomerular mononuclear cells may also cause disruption of BC which facilitates entry of activated periglomerular cells and fibroblasts into BS leading to progressive fibrous crescent formation.

PURPOSE: This study provides useful basic information about caring for elderly women. It also promotes understanding by confirming what can vitalize the women and improve quality of life in elderly women as they continue to become important in the society which is moving towards being an "aged society". METHOD: Grounded theory a qualitative research method, was use to develop new thesis regarding life's vitality in elderly women. Thirteen women participated in the research. They were women without any problems in perception or communication and who agreed to participate in the research. RESULT: The results, using analysis process of Strauss and Corbin (1990), showed that life's vitality in elderly women is to bring well-being through vitalization against weakness. CONCLUSION: Based on such these results, this study will be helpful to nursing mediation and policy development which will improve the quality of life of elderly women through better understanding and promotion of life's vitality.

BACKGROUND/OBJECTIVES: Few studies have provided evidence of the association between diet quality and dental caries. This study aimed to examine the association between diet quality and untreated dental caries in a Korean representative population. SUBJECTS/METHODS: The study population included a sample of 13,815 participants, aged ≥ 19 from the Korea National Health and Nutrition Examination Survey during 2013–2015. The explanatory variable was diet quality and the outcome variable was untreated dental caries.Untreated dental caries were defined by the number of decayed teeth recorded according to the criteria established by the World Health Organization. Diet quality was defined by using the Korean Healthy Eating Index (KHEI) through the 24-h recall methods. We assessed the association between diet quality and untreated dental caries while adjusting for age, sex, education, income, smoking status, dental visits, toothbrushing frequencies, obesity, and diabetes mellitus. RESULTS: The mean overall KHEI scores in the untreated dental caries group were significantly lower than those in the group without untreated dental caries. Significant differences were observed in the untreated dental caries group based on the KHEI quartiles (P < 0.001). After adjusting for potential confounders, the quartiles of KHEI scores showed an association with untreated dental caries, demonstrating a dose-effect trend (odds ratio [OR], 1.57; 95% confidence interval [CI], 1.35–1.84 for 1st quartile; OR, 1.38; 95% CI, 1.19–1.59 for 2nd quartile; OR, 1.32; 95% CI, 1.14–1.53 for 3rd quartile; reference quartile highest]). CONCLUSIONS The findings indicated an inverse association between diet quality and untreated dental caries in Korean adults. Healthcare providers should take into account the significant role of diet quality in preventing and managing oral health.
