BACKGROUND: The purpose of this study was to analyze the relationships between cardiorespiratory fitness and body mass index (BMI), metabolic syndrome risk factors, homeostasis model assessment-insulin resistance (HOMA-IR), and high sensitivity C-reactive protein (hsCRP) in male high school students in Korea. Furthermore, the effects of the cardiorespiratory fitness levels on these four factors were examined. METHODS: The level of cardiorespiratory fitness, BMI, percent body fat, waist circumference (WC), systolic blood pressure, glucose, triglycerides (TG), high-density lipoprotein-cholesterol (HDL-C), HOMA-IR, and hsCRP of 227 male high school students were measured. Analyses of multiple correlation and simple regression were applied. RESULTS: The results showed that the level of cardiorespiratory fitness correlated negatively with BMI, percent body fat, WC, TG, and HDL-C, in addition to HOMA-IR and hsCRP, and strongly influenced BMI, percent body fat, WC, TG, HDL-C, HOMA-IR, and hsCRP. Comparative analysis of our subjects showed that higher cardiorespiratory fitness levels had positive effects on BMI, metabolic syndrome risk factors, HOMA-IR, and hsCRP. CONCLUSIONS: This study found that there are close correlations between cardiorespiratory fitness and BMI, metabolic syndrome risk factors, HOMA-IR, and hsCRP. It also showed that, compared to lower levels of cardiorespiratory fitness, higher levels had beneficial effects on BMI, metabolic syndrome risk factors, diabetes, and cardiovascular disease risk factors.

PURPOSE: Recently, in an experiment using animals, radiation therapy using a laser or Tending Diancibo Pu (TDP) has been shown to be effective in treating scars on the skin by increasing the production of fibroblast cell and collagen and by accelerating the process of epithelization. The purpose of this study is to examine the effectiveness of TDP radiation therapy in treating human burn injuries in terms of the frequency of treatment, the timing of eschar separation, and the duration of treatment. METHODS: In the treatment group, the burn area of the patients was first sterilized with saline solution and potadin solution and covered with one vaseline gauze. Then, the burn area was radiated every other day by using TDP for 20 minutes at distance of 20-25 cm, at radiant plate temperature of 250-280oC. In the cases of control group, the burn area of the patients was first sterilized with saline solution and potadin solution and covered with one vaseline gauze. Then, the area was covered with one burn gauze and bandaged. The treatment was conducted every other day. RESULTS: In cases of superficial second degree burn injuries, the difference between the treatment and the control groups was 1.34 in terms of the frequency of treatment. In the cases of both superficial and deep second degree burns, the differences between the treatment and the control groups were 3.47 in terms of the frequency of treatment, 0.63 weeks in terms of the timing of eschar separation, and 6.03 days in terms of the duration of treatment. All these differences were statistically significant. CONCLUSION: From the experiment, it can be concluded that TDP radiation therapy is more effective in treating human burn injuries than conventional treatment in terms of the of the frequency of treatment, the timing of eschar separation, and the duration of treatment.

We report two cases of ectopic epididymal ducts and efferent ductules in the testicular appendices (TAs) of adult men with normally descended testes. In both cases, a sessile TA was incidentally found at the upper pole of the right testis during the scrotal hydrocelectomy. Microscopically, a few closely arranged tubules were detected within the TA. In the first case, the tubules were lined with a pseudostratified columnar epithelium with numerous, long microvilli, and were surrounded by a smooth muscle coat. In contrast, in the second case, the tubules had a wavy luminal surface, because ciliated columnar cells alternated with groups of cuboidal cells. In both cases, strong CD10 immunoreactivity was observed in the luminal border of the lining epithelium. Surgical pathologists should be aware of the presence of both ectopic epididymal ducts and efferent ductules that can occur in TAs, in order to avoid misinterpretation as transected, functional reproductive structures.

BACKGROUND: Spontaneous bacterial peritonitis(SBP) is an infection of ascitic fluid without any apparent intra-abdominal foci of sepsis. Although the definitive diagnosis of SBP requires a positive ascitic fluid culture, causative organisms are not isolated in up to 65% of patients with well defined SBP probably due to inadequate culture techniques. We compared two culture methods for ascites : conventional and blood culture method. METHODS: From June 1989 until December 1994, the blood culture method of ascitic fluid culture was performed(Group A). Ascitic fluid was inoculated at the bedside directly into one aerobic and one anaerobic BACTEC blood culture bottles. During the period from January to December 1995, ascitic fluid was processed by the conventional culture method of inoculating a sample of ascitic fluid on sheep blood agar, MacConKey agar, brucella agar and into thioglycolate broth(Group B). RESULTS: Ascites cultures were positive more frequently with the blood culture method(25 of 56, 44.6%) than with the conventional method(113 of 370; 30.5%) (P<0.05). Sixteen of the 56 patients in Group A had SBP and 29 had culture negative neutrocytic ascites(CNNA) while 66 of the 370 patients in Group B had SBP and 229 had CNNA The conventional method recovered more contaminating microorganisms than the blood culture method(17.7% vs 6.9%). CONCLUSIONS: The inoculation of ascitic fluid into the BACTEC blood culture bottles at the bedside is more sensitive than the conventional method of inoculation on solid media at the laboratory bench in the recovery of pathogens in SBP and should be used routinely for the optimum diagnosis of SBP.

Renal angiography has applications in the diagnosis of renal tumor and renovascular hypertension, and provides important anatomical information that can influence the surgical management. Recently the approach to the vascular system for diagnosis by means of Seldinger technique hag been expended to include a variety of therapeutic manner. So, embolization of renal carcinoma is being used with increasing frequency. Radiologic findings associated with presenting symptoms and signs were analysed in 51 cases of renal angiography, during the period of October 1978 to October 1982. The following results were obtained. 1. Male to female ratio was approximately 1:1 and peak incidence was in the sixth decade. 2. The main symptoms and signs of patients were hematuria, flank pain, hypertension and palpable mass, in order of frequency. 3. In 7 hypertensive patients with delayed visualization on the excretory urogram. angiography shows 2 cases of renal artery stenosis, one case of Takayasu's disease and absence of abnormal vasculature in 4 cases. 4. It is suggested most valuable technique for correct diagnosis of renal vascular disease. some of other congenital anomalies, and renal vascular mapping for renal surgery.

Actinic reticuloid as a manifestation of chronic actinic dermatitis (CAD) is a rare dermatosis whose clinical and histologic features resemble other types of pseudolymphomas including mycosis fungoides and Jessner's lymphocytic infiltration, and it is regarded as an eventual stage of various photodermatoses like photosensitive eczema or persistent light reaction or chronic photoallergic contact dermatitis and so on. Phototests in the patients with actinic reticuloid usually reveal hypersensitivity to UVB, UVA, and sometimes to visible light. We present a case of actinic reticuloid in a 65-year-old male, whose skin lesions developed as erythematous lichenified infiltrating plaques on the face at first, and then spread themselves onto the upper trunk later. Histologically those skin lesions showed the aggregation of atypical lymphocytes and photobiologically the results of phototests revealed photosensitivity to UVB and UVA.

BACKGROUND: For the evaluation of pulmonary nrtery branches after operation of right ventricular outflow obstructive disease, we reviewed the usefulness of both simple X-ray and lung perfusion scan with 99mTc-macroaggregated albumin compared with cardiac angiography. METHODS: From March, 1986 to July, 1993, at Seoul National University Children;s Hospital, we chose 23 cases who underwent both simple X-ray and cardiac angiography among the patients who had distinct difference between right and left pulmonary blood flow in lung perfusion scan after operation of right ventricular outflow obstructive disease. So we calculated the ratio of right and left pulmonary blood flow and Spearman correlation coefficient. RESULTS: Of the 23 cases, 17 cases were tetralogy of Fallot, 4 cases pulmonary atresia, 1 case double outlet right ventricle, and 1 case truncus arteriosus. The mean age at poeration was 27 months, and the mean postoperative follow-up period was for 68 months. The correlation coefficient between cardiac angiography and simple X-ray was 0.86(p<0.01), and that beteen cardiac angiography and lung perfusion scan was 0.80(p<0.01). CONCLUSION: The cardiac angiography has been known as the best diagnostic tool for the evaluation of pulmonary artery branches after operation of right ventricular outflow obstructive ddisease, but we proposed that the lung perfusion scan should be widely used because its results were similar with those of cardiac angiography.

A 44-year-old man had Sweet's syndrome (acute febrile neutrophilic dermatosis), accompanied by erythematous tender subcutaneous nodules resembling erythema nodosum(EN). The EN-like lesions histologically showed a septal panniculitis with predominantly neutrophilic in-filtrates. The association of Sweet's syndrome with EN seems to be uncommon and only a few cases have been reported until the present. We describe a patient with Sweet's syndrome associated with acute EN.
