STATEMENT OF PROBLEM: For a long time, many of denture base acrylic resins have been used for edentulous and partial edentulous patients because of easy manipulation and good mechanical properties, but its esthetic aspect has not been commented enough. Denture base acrylic resins also has caused esthetic problems due to discoloration or staining as in esthetic restoration. Many researches and reports have treated the problems and accomplished esthetic improvement. But these researches and reports dealt with general food colors or beverages, not with fermented foods. PURPOSE: This study is designed to assess what fermented foods, such as soy sauce, gochujang, and toenjang that many of Koreans have taken in, influence on the color and hardness variation of denture base acrylic resins. MATERIALS AND METHODS: For the procedure, twelve disks per 4 denture base acrylic resins were fabricated with a thickness of 2mm and 16mm in diameter. Each seven specimen were measured for discoloration with spectrophotometer, while the others, five specimen, for surface hardness change with Barcol hardness tester, over time. Each 12 specimen were immersed into the 4 beakers of fermented foods(soy sauces, gochujangs, toenjangs, deionized water), and L*, a*, and b* values were measured for the color difference(_E*), on the 1st, 7th, and 28th day with spectrophotometer, with the measurement of surface hardness change. Each data observed was processed statistically. RESULTS: The findings are as follows; Discoloration 1. All of denture base resins was not influenced by the kind of fermented foods, except for QC20. 2. Soy sauce and red pepper paste caused more change for denture base resins than deionized water and soy bean paste, except for Perform. 3. Most significant change was shown in Lucitone199., whereas Perform. results in the least change for all immersed solution, with no statistical significance. Hardness change 1. Barcol hardness values in deposited specimens have been changed low degree, but with significant statistical change according to the kind of food and duration. 2. Lucitone199. has significantly lower Barcol hardness value than others do. CONCLUSION: Based on the above results, it suggests that the habitual intake of fermented foods is not helpful for the color stability of denture base acrylic resins because Soy sauce and red pepper paste mainly caused discoloration and surface hardness change. Particularly Lucitone199. shows specific discoloration and low surface hardness values. Therefore, it is recommended giving caution patients with denture of Lucitone199. especially against the habitual intake of fermented foods like soy sauce and red pepper paste.

Feeding habits and sugar contents contents affect dental health and ultimately the total health of young chidren. Nursing bottle caries, nursing botte syndreme, bottle-propping caries are synonymous term for a devastaing condition that may render young children dental cripples. Typically, the primary maxillary incisors are affected most severely and mandibular incisors are seldom involved. We report 4 cases of nursing bottle caries with a brief review of related literatures and references.

PURPOSE: To describe our experience concerning clinical features, methods of treatment and outcomes of separation of the symphysis pubis during childbirth. MATERIALS AND METHODS: We experienced 26 cases during a period of 6 years from March 1992 to January 1998. Retrospectively, we analysed 23 cases which could be followed up for more than a year, each with separation of the symphysis pubis associated with childbirth. Method of treatment was pelvic sling and absolute bed rest in 18 cases of 23 cases, the others were treated with bed rest and early mobilization. RESULTS: Clinical symptoms and physical findings were similar in all cases. The duration of symptom was from 3 weeks to a year (mean=3.2 months), the size of the gap on simple X-ray ranged from 6 mm to 28 mm (mean=16 mm) initially and from 3 mm to 11 mm (mean=4.7 mm) finally. Outcomes were good in all cases with conservative treatment, although final radiologic fingings were normalized, widening, sclerosis, erosion or osteophytes. CONCLUSION: Separation of the symphysis pubis during childbirth was treated well with conservative treatments, although variable radiologic findings were noted in final X-ray finding.

BACKGROUND AND OBJECTIVES: The degree of diastolic dysfunction may explain the difference in clinical symptoms between patients with similar degrees of systolic dysfunction. Pseudonormal mitral filling pattern with increased left ventricular filling pressure is a transitional stage of diastolic dysfunction and is difficult to distinguish from normal. Preload is one of factors affecting the diastolic filling patterns and mitral flow patterns may be influenced by changes in preload in the absence of changes in the left ventricular pressure-volume curve. The changes in the mitral flow velocities caused by preload reduction may be useful in distinguishing patients with a pseudonormal pattern from those with normal. The aim of this study was to establish whether the effect of changes in pulmonary venous flow pattern by preload reduction may be useful in distinguishing pseudonormal pattern from normal. MATERIALS AND METHODS: This study included 40 patients (men 25, female 15, average age 51.0+/-11.2 years) underwent left side cardiac catheterization among patients with normal or pseudonormal patterns. All patients with pseudonormal group had increased LVEDPr (>15 mmHg). The Doppler mitral inflow & pulmonary venous flow parameters at baseline and during reduction of preload using Valsalva maneuver were recorded. RESULTS: 1) There were no difference in sex, diabetes mellitus, hypertension and lipid profiles between both groups. The left ventricular systolic function was better and mean age was younger in normal than pseudonormal group (p<0.05). The incidence of coronary artery disease was more frequent and LV mass was more increased in pseudonormal than normal group (p<0.05). 2) E and A velocities were significantly decreased but E/A ratio was still <0A65B> 1.0 during Valsalva maneuver in normal group (p<0.05). In pseudonormal group, E velocity was significantly decreased but A velocity was not significantly changed and the E/A ratio was <1.0 during Valsalva (p<0.05). Therefore the change revealed masked LV relaxation abnormality pattern. 3) S and D velocities of pulmonary venous flow were significantly decreased and S/D ratio was significantly increased in both groups (p<0.05). The % changes before and after Valsalva maneuver showed that S velocity was less decreased, D velocity was more decreased and S/D ratio was more significantly increased in pseudonormal than normal group (p<0.05). That revealed masked LV relaxation abnormality pattern. CONCLUSIONS: The Valsalva maneuver for preload reduction is a relatively simple, easily applicable, safe and reproducible method of acutely reducing venous return. The assessment of changes in pulmonary venous flow pattern by preload reduction may be helpful in distinguishing pseudonormal and normal diastolic function in addition to changes in mitral inflow pattern.

It has long been known that Vasopressin could increase the urinary sodium and chloride excretion. The exact mechanism and site of action, however, have not yet been explained. Experiments were performed whether the renal effects were the same in both cortical and juxtamedullary nephron in decorticated kiddney model. Heat-decortication was car ried out in the left kidney immersed in water kept at 52oC for 5 minutes. In 90% of cases, outer 2/3 of the cortex was necrotized as revealedd at the time of experiment on 8th day. The right kidney underwent the same procedure except that the temperature of water was kept at 39oC, and served as control. Urine flow and fractional excretion of urine were increased by the arginine vasopressin infusion in both kidney, but the diffferences were not significant. There were no signifficant changes in glomerular filtration rate and rrenal plasma flow in doses of 5 and 10 mu/kg/minute. Responsiveness of decorticated kidney was less than the control kidney. Increments of fractional excretion of potassium were not significantly different. From thhese results, it is suggested that the responsiveness of the cortical and juxtamedullarry nephron to the arginine vasopressin may not be the same. The mechanisms of the differences were discussed.

BACKGROUND: Pulmonary venous flow velocity pattern (PVFVP) is widely used to assess LV diastolic function. It is known that the parameters of PVFVP have a significant correlation with the ratio of peak early diastolic filling velocity (E) to peak filling velocity at atrial contraciton (A) measured in the transmitral flow. However, the correlations between parameters of superior vena caval flow (SVCF) and transtricuspid E/A ratio have not been reported. Therefore the present investigation was performed to elucidate these correlations. METHODS: Fifty patients (26 men, mean age 63.1+/-11.1 years), who did not have significant tricuspid valvular disease and restrictive filling pattern on tricuspid and superior vena caval doppler, were included in this study. SVCF was recorded with the transducer positioned at subxiphoid area and the sample volume placed 2 cm within the superior vena cava. Blood flow across the tricuspid valve was obtained from standard four chamber view or modified parasternal four chamber view with the sample volume placed on leaflet tips. Recording was made during midexpiratory apnea. The following doppler parameters were measured: transtricuspid E and A velocity, E/A ratio: systolic (S) and diastolic (D) peak velocities and time velocity integrals (TVI), S/D velocity ratio, S/D TVI ratio, atrial reversal peak velocity (ArV) and TVI (ArTVI) in SVCF. RESULTS: 1) In SVCF, S velocity (63.7+/-11.8 cm/s vs 73.4+/-13.6 cm/sec, p<0.05), S TVI (17.4+/-3.6 cm vs 21.1+/-6.2 cm, p<0.05), ArV (30.0+/-6.9 cm/s vs 37.2+/-7.3 cm/s, p<0.005), and ArTVI (2.7+/-0.8 cm vs 3.3+/-0.8 cm, p<0.01) were significantly decreased in group E/A>1. And D TVI (7.1+/-3.0 cm vs 5.2+/-3.1 cm, p<0.05) and D/S TVI ratio (0.41+/-0.13 vs 0.26+/-0.14, p<0.05) were significantly increased in group E/A>1. 2) As E/A ratio increased, diastolic TVI (r=0.315, p<0.05) and D/S TVI ratio (r=0.448, p<0.001) increased, and ArTVI (r=-0.376, p<0.01) and ArV (r=-0.416, p<0.01) decreased. 3) As E peak velocity increased, SVCF D peak velocity increased (r=0.305, p<0.05). CONCLUSIONS: Tricusupid E/A ratio has positive correlations with D TVI and D/S TVI ratio, and negative correlations with ArTVI and ArV. But there were no correlations in S velocity, D velocity, and S/D velocity ratio as the relation of mitral E/A ratio with PVFVP.

OBJECTIVES: The erythrocyte sedimentation rate (ESR) is a marker for inflammation, and it has been identified as a risk factor for atherothrombotic cardiovascular disease. The aim of this study was to determine the relationship between the plasma ESR level and nocturnal oxygen desaturation or other polysomnographic variables and to examine the role of obesity in patients with obstructive sleep apnea syndrome (OSAS). METHODS: This retrospective study included 72 patients with a diagnosis of OSAS who underwent overnight polysomnography and routine blood tests between July and December of 2005. We compared the plasma ESR level with the sum of all the polysomnographic variables and divided the patient group into obese and non-obese patients. RESULTS: The mean ESR level was 8.45 mm/hr. There was a significant difference in the ESR level between genders (P<0.001). A significant correlation was found between the percentage of time spent at a SpO2 below 90% and the ESR level in the obese group (BMI > or =25, N=43, P=0.012). In addition, the ESR levels had a positive correlation with age in the obese group (P=0.002). However, there was no significant correlation with the percentage of time spent at a SpO2 below 90% in the whole group of patients and in the non-obese group (BMI <25, N=29). The ESR level showed no correlation with the other polysomnographic variables. CONCLUSION: The duration of deoxygenation in obese patients with OSAS may be associated with the ESR level which is an independent predictor of cardiovascular disease.
