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.

BACKGREOUND: Cerebral damage caused by hemorrhagic shock presents an important challenge for critical care medicine. The type of fluid to resuscitate hemorrhagic shock is important for the outcome of such patients. Pentastarch is low-molecular-weight hydroxyethyl starch, which increases cerebral blood flow (CBF) by plasma volume expansion and compensatory vasodilation, and improves the microcirculation in the ischemic brain area by reducing the blood viscosity. METHODS: The authors continuously determined CBF and CMRO2 in 10 mongrel dogs weighing 20.1 +/- 0.8 kg with posterior sagittal sinus outflow method. Dogs were subjected to the 20 minute-period of hemorrhagic shock to a mean arterial pressure of 40 mmHg. The shock phase was followed by resuscitation with the same volume of 10% pentastarch as blood loss. The authors assessed the changes of CBF, CMRO2, and CBF/CMRO2 ratio immediately and 30, 60, 90, 120 minutes after pentastarch infusion. Brain water content was assessed by the wet-dry weight method. RESULTS: CBF was increased above the control level, immediately and 30 minutes after 10% pentastarch infusion (p<0.05), and approximated to the control level for the remaining time. CMRO2 was increased, immediately and 30, 60, 90 minutes after 10% pentastarch infusion (p<0.05), and approximated to the control level at 120 minutes. CBF/CMRO2 ratio was recovered to the control level after 10% pentastarch infusion. Brain water content was not significantly different from the normal value of dogs. CONCLUSION: 10% pentastarch may be used with safety to resuscitate hemorrhagic shock because it recovers the balance between the cerebral oxygen supply and demand, and does not cause cerebral edema.

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.

BACKGROUND: Direct laryngoscope may be less useful under conditions of limited visualization. Light wand is a lighted stylet to transilluminate neck tissues allowing intubation without visualization. Thus, difficult intubation due to anatomy can be overcome. For comparison of light wand and direct laryngoscope, we checked time to intubation (TTI), success rate, relation of TTI and thyromental distance (TMD), and change of blood pressure and heart rate after intubation. METHODS: We selected and randomly allocated sixty adults to direct layngoscope group (D) and light wand group (L). Without premedication, propofol and vecuronium were injected for intubation. Time to intubation was measured from the time of grasping direct laryngoscope or light wand until the time of inserting endotracheal tube into trachea. We checked the change of blood pressure and heart rate after intubation, and studied the correlation of TTI and TMD. RESULTS: TTI was 16.5 sec (6.53~115.3 sec) for group D and 11.8 sec (4.31~36.0 sec) for group L. There was no significant difference between the groups. The rise of blood pressure and heart rate was less with light wand. There was a correlation of [TTI]=1248- 388[TMD]-30[TMD]2 in group L patients whose TMD is less than 7 cm. CONCLUSION: Compared with direct laryngoscope, light wand is as easy to use and can be more effective especially for patients whose anatomy may make intubation difficult or whose cardiovascular system is unstable.
