BACKGROUND: The obese patients increased recently in Korea due to excessive energy intake and decreased physical activity. We are well known that obesity is associted with an increased risk of cardiovascular disease, angina pectoris, hypertension, but not known to influence of weight gain to change in cardio-vascular risk factors. Once, the study of obesity are many but the study of influence of weight gain are small in Korea. This study investigated to influence of weight gain in cardio-vascular risk factors. METHODS: We gatherd case and control group among persons who has taken twice medical examination except disease person from October 1990 to October 1995 at SungAe General hospital. In our study, total 167 case, compare weight gain group(>3kg) with control group to change in cardiovascular risk factor. RESULTS: Sex, age, smoking history, obesity index were not statistically significant difference between two group in the first medical examination. systolic blood pressure, diastolic blood pressure, fasting blood sugar, HDL, total cholesterol/HDL were not statistically significant difference between two group for weight gain. Total cholesterol and triglyceride, LDL were stastistically significant increased. CONCLUSIONS: Weight gain was increased of total cholestrol and triglyceride, LDL, so weight control was important.

Progressive renal fibrosis is considered to be the final common pathway leading to chronic renal insufficiency, however, the mechanism regarding renal fibrosis in renal injury is not well understood. Recently, several kinds of cytokines have been known to be related to fibrosis after renal injury. The interaction between elements regulating fibrogenesis would be better understood by looking at the effect of TGF-beta1 on the synthesis and accumulation of extracellular matrix, especially collagenous proteins. Crescentic glomerulonephritis (CGN) was induced in New Zealand White rabbits by administration of guinea pig anti-GBM IgG after sensitization with guinea pig IgG; and their kidneys were analyzed for the development of crescents and fibrosis through sequential renal biopsies. Serum creatinine levels in a time course progressively increased until day 15. We semi-quantitatively assayed the levels of the expression of alpha1(I) collagen mRNA and TGF-beta1 mRNA factored for GAPDH mRNA using RT-PCR. We observed a progressive interstitial fibrosis and the expression of collagen I both in the cortex and medulla. The effect of repeated renal biopsy itself on pathology and on the expression of alpha1(I) collagen mRNA and TGF-beta1 mRNA in a time course were not significant, but a very mild increase of the expression of alpha1(I) collagen mRNA was noted at day 15. Histology showed a progressive crescent formation and interstitial fibrosis in a time course that roughly paralleled the expression of alpha1(I) collagen mRNA in both cortex and medulla. TGF-beta1 mRNA was hardly expressed at day 0 in cortex as well as in medulla. It was elevated from day 1, peaked at day 7, and then decreased. In medulla, TGF-beta1 mRNA was noticeably expressed at day 1, peaked at day 4, and then decreased. The expression of alpha1(I) collagen mRNA was seen even before inducing CGN. It was gradually and continuously increased until day 15 both in cortex and medulla. These results suggest that the expression of TGF-beta1 mRNA precedes that of alpha1(I) collagen mRNA in the early stage of CGN and has a central role for provoking the accumulation the collagen I, the most representative interstitial extracellular matrix, in the rabbit model CGN induced by anti-GBM antibody. We conclude that the measurement of the expression of TGF-beta1 mRNA and/or alpha1(I) collagen mRNA in a biopsy sample can be a useful predictor for renal outcome.

A retrospective analysis was done on 68 patients with primary superficial bladder cancer between September 1989 and December 1995. We evaluated the predictive value of urine cytology in the recurrence and the progression of superficial bladder cancer. Positive cytology was shown in 52.9% (36/68) and was significantly associated with tumor grade (p=0.001). The recurrence rate in patients with negative cytology was 28.1% (9/32) compared to 77.8% (28/36) in those with positive cytology (p=0;001). No patients of negative cytology had tumor progression while 4 out of 36 (11.1%) patients of positive cytology had progression to invasive or metastatic disease. In conclusion, urinary cytology appears to be a significant prognostic factor in superficial bladder cancer.

PURPOSE: We reported the CT and MR findings of 2 cases with Sturge-Weber syndrome which were not accompanied by facial nevi. MATERIALS AND METHODS: They were examined with both CT and MR in one case and with MR only in the other case. RESULTS: CT was better than MR in the demonstration of the characteristic cortical calcification. MR was superior to CT in the depiction of the abnormalities of the surrounding parenchyma and the intense enhancement of pial angiomatosis with Gd-DTPA enhancement. CONCLUSION: Gd-DTPA enhanced MR imaging could be useful in the demonstration of the presence and extent of pial angiomatosis in patients with suspected Sturge-Weber syndrome.

PURPOSE: This study was conducted to develop nursing standards for medical patients with Coronary Artery Disease (CAD) patients. METHODS: This study was a methodological study. The content of nursing standards for medical patients with CAD developed in this study was validated. The nursing standards of cardiovascular nursing developed by the American Nurses Association (2008), the nursing standards developed by the Korea Nurses Association (2003) and a clinical manual of patients with CAD developed by K teaching hospital were reviewed. Literature regarding CAD nursing standards was also reviewed. The basic contents of nursing standards for medical patients with CAD were selected by an expert group including two nursing faculties, a cardiovascular unit manager, and two cardiologists. A pilot study was conducted then in real clinical settings, in which includes cardiovascular outpatient clinic, cardiovascular inpatient units, and cardiac intensive care units to evaluate clinical suitability of the nursing standards. RESULTS: The final version of the nursing standards for medical patients with CAD included 12 standards, 24 criteria, 38 indicators and 92 nursing activities. CONCLUSION: The nursing standards developed in this study can be used in evaluating quality of nursing service and in educating nurses who are involved in patients with CAD.

Paroxysmal nocturnal hemoglobinuria(PNH) is a rare, acquired disease involving multiple hematopoietic lines. Characteristics of PNH are intrinsic hemolytic anemia, iron deficiency anemia and venous thrombosis. report a case of PNH with characterostoc MR and CT findings. The signal intensity of renal cortex was lower than that of medulla on both T1- and T2- weighted MR imaging. On T2 weighted MR images, the liver showed very low signal intensity but the signal intensity of the spleen was normal. On precontrast CT the attenuation of renal cortex was higher than that of renal medulla and the attenuation of liver was higher than that of the spleen. These findings of MR imaging and CT were the result from the deposition of hemosiderin in the cells of proximal convoluted tubules and transfusional hemosiderosis of liver.

To compare the differences between hemodialysis and essential hypertension patients and its affecting factors of left ventricular hypertrophy and left ventricular systolic dysfucntion in patients with hemodialysis, M-mode and two dimensional echocardiography were performed in 77 essential hypertension without azotemia and 78 chronic renal failure patients receiving maintenance hemodialysis. M-mode measurement including LV mass (192.56+/-63.6g vs 300.01+/-95.99g, P=0.000), r/th (radius/LV thickness, 4.41+/-0.97 vs 4.74+/-1.0, P=0.039), LV dimemsion and fractional shortening (4.68+/-0.6 vs 5.63+/-0.97, P=0.000, 30.0+/-19.7% vs 36.6+/-97%, P=0.000 respectively) showed more severe eccentric LV hypertrophy and LV dysfunction in patients with hemodialysis than those of essential hypertension. Using Pearson correlation in hemodialysis patients, Interdialytic weight gain was positively correlated with LVEDD (r=0.318, P=0.005). In addition to the determinant, serum PTH level was negatively (r=-0.344, P=0.002) and Kt/V (r= 0.0487, P=0.003) was positively correalated with systolic function. The hypertension and dialysis duration, patient's age, had no relationship with LV function and mass in this study. In Conclusion, LV hypertrophy and LV systolic dysfunction occur more frequently in hemodialysis patients than in essential hypertension patients. And the LV systolic dysfunction, which is acutally related with the patient's quality of life, was partially explained by serum parathyroid level and Kt/V. But additional laboratory and prospective clinical studies are needed to further elucidate the mechanisms involved in the development of LVH and LV impairment in hemodialysis patients.

PURPOSE: Alveolar bone develops with tooth eruption and is absorbed following tooth extraction. Various ridge preservation techniques have sought to prevent ridge atrophy, with no superior technique evident. Collagen has a long history as a biocompatible material. Its usefulness and safety have been amply verified. The related compound, atelocollagen, is also safe and displays reduced antigenicity since telopeptides are not present. MATERIALS AND METHODS: The current study evaluated whether the Rapiderm® atelocollagen plug (Dalim Tissen, Seoul, Korea) improves tissue healing of extraction sockets and assessed the sequential pattern of bone regeneration using histology and microcomputed tomography in six beagle dogs. To assess the change of extraction socket, hard tissues were examined 2, 4, 6, and 8 weeks after tooth extraction. RESULT: The experimental groups showed better bone fill with slow remodeling process compared to the control groups although there was no statistical difference between groups. CONCLUSION: The atelocollagen seems to have a tendency to slow bone remodeling in the early phase of healing period and maintain remodeling capacity until late phase of remodeling. Also, use of atelocollagen increased the bone-to-tissue ratio compared to healing of untreated extraction socket.
