The authors experienced a case of embryonal rhabdomyosarcoma. The patient was 13 years old bov who had exophthalmos, ocular deviation to upper direction and visual disturbance of his left eye. We excised the exposed mass of tumor by exploration of the orbit and postoperative irradiation with Cobalt-60 was followed. There were no signs of recurrence of the tumor or metastasis to the other part of body until now, 7 months after surgery. We had a study of the histopathologic findings for a case of rhabdomyosarcoma with a brief review of relating literature.

STUDY DESIGN: A case report. OBJECTIVES: Lumbar burst fracture was treated with operation, which delayed recollapse of L1 and led to conus medullaris syndrome. SUMMARY OF LITERATURE REVIEW: After operation, conus medullaris syndrome causing by delayed recollapse is not frequently reported. MATERIALS AND METHODS: A 56-year-old male was admitted with lower back pain caused by a fall. Radiologic findings showed L1 burst fracture with about 42% of height loss. There was no neurologic deficit. Posterior fusion was performed using instrumentation. Five weeks after the operation, the patient was admitted for urination and defecation difficulty. Radiologic findings showed that the L1 had recollapsed with about 38% of height loss. To resolve the problem, anterior surgery was performed. RESULTS: Two years after surgery, bladder and anal sphincter dysfunction wasn't recovered. CONCLUSIONS: Lumbar burst fracture should be follow up carefully until union of the fracture because burst fracture leads to delayed recollapse.

PURPOSE: This study was designed to investigate the effects of polyamines on rabbit seminal vesicular contractility. MATERIALS AND METHODS: The polyamines; putrescine, spermidine and spermine, were added to deepithelized and precontracted seminal vesicle strips, with either 10 4M norepinephrine (NE), 10 4M acetylcholine (ACh) or 70mM KCl, in organ chambers to obtain cumulative concentration response curves. A whole cell mode patch clamp study was also performed to observe the effects of the polyamines on the L-type calcium channel activities. RESULTS: The polyamines elicited concentration-dependent relaxations of the precontracted strips with the NE, ACh and KCl. The spermine showed the most potent relaxation response. Both extracellular and intracellular application of the spermine decreased the L-type calcium channel currents. CONCLUSIONS: Spermine more potently inhibited the seminal vesicle contraction than putrescine or spermidine, which suggests the polyamines may play a role in maintaining the basal tonicity of seminal vesicle in a flaccid state. The spermine-induced relaxation response seems to be related with an inhibition of the L-type calcium channel activities.

PURPOSE: The effects of leptin on female sexual behaviors are controversial, and studies on this topic are limited. The objectives of this study were to evaluate the direct effects of leptin on clitoral vasoreactivity in vitro and to determine the mechanism of action. MATERIALS AND METHODS: Isometric tension studies were conducted to determine the effects of pretreatment with leptin (10(-8) M) on the contractile responses of rabbit clitoral corpus cavernosal smooth muscle strips. The effects of leptin were assessed on precontraction induced by phenylephrine (PE; 10(-9)-10(-4) M) and KCl (35-140 mM). We also examined the effect of leptin on relaxation induced by acetylcholine (ACh; 10(-9)-10(-4) M), verapamil (10(-10)-10(-6) M), and sodium nitroprusside (10(-9)-10(-4) M) in PE-precontracted (10(-5) M) strips. RESULTS: Leptin enhanced ACh-induced relaxation in PE-precontracted strips. L-NAME pretreatment significantly reduced the effect of leptin on ACh-induced relaxation, whereas L-arginine potentiated the effect of leptin. Leptin decreased the KCl-induced contractile responses. Leptin increased verapamil-induced relaxation responses. The relaxation effects of leptin on KCl-induced contraction were inhibited by 10(-5) M methylene blue and L-NAME pretreatment. CONCLUSIONS: A high concentration of leptin enhances ACh-dependent relaxation in clitoral cavernosal smooth muscles. These relaxation effects of leptin may occur through an NO-dependent mechanism and voltage-dependent calcium channel blockade.

PURPOSE: This study aimed to investigate the effects of vasopressin and desmopressin on the contractile and relaxative responses of rabbit cavernosal smooth muscle. MATERIALS AND METHODS: Isometric tension studies were conducted to investigate the effects of vasopressin(10(-14)-10(-8)M) and desmopressin(10(-14)- 10(-8)M) on the contraction and relaxation responses of rabbits cavernous muscle strips in an organ bath. The effects of pretreatment with phenylephrine(10(-5)M), L-NAME(10(-5)M) and indomethacin(10(-5)M) on the contraction and relaxation responses of the vasopressin and desmopressin were also investigated. The statistics were analyzed by Student's t-test and ANOVA. RESULTS: Vasopressin contracted the strips in a dose-dependent manner, while desmopressin did not. The phenylephrine-induced contraction was dose-dependently increased by vasopressin, but it was dose-dependently relaxed by desmopressin. L-NAME pre-treatment did not block the relaxation response, but indomethacin pre-treatment did. Vasopressin- induced contraction occurred the via V(1) receptor, while desmopressin- induced relaxation occurred via the V(2) receptor. CONCLUSIONS: Vasopressin, in pathophysiological circumstances, would worsen erectile dysfunction. On the contrary, desmopressin, which may induce an endothelium-dependent relaxation of the cavernous smooth muscles, would be good for erectile function.

MRSA strains cause serious nosocomial infections. The rate of MRSA among Staphylococcus aureus isolated in Korea is about 70 - 80%. The treatment for MRSA infection is vancomycin. But vancomycin has several side effects and its therapeutic rate is 60 - 75%. Therefore the disinfectants play an important role in preventing and treating MRSA infection. In this study, 44 MRSA isolates were obtained from Wonkwang University Hospital, and examined for the efficacy of disinfectants commonly used in hospital. The tested disinfectants were chlorohexidine (Hibitan(R)), H2O2, tego, Gentian Violet, potadine, chlorohexidine gluconate (Microshield(R)), boric acid, alcohol, zepanon, acetic acid, and combinations of these disinfectants. MRSA studied were killed after exposure to chlorohexidine gluconate (Microshield (R)), alcohol, zepanon, alcohol+potadine, and alcohol+Gentian Violet within 30 seconds. But, tego, boric acid, and Gentian Violet+acetic acid could not kill MRSA after 30 minutes. Agar dilution minimal inhibitory concentration test was done with cephalothin, ciprofloxacin, clindamycin, erythromycin, fusidic acid, gentamicin, mupirocin, oxacillin, penicillin G, rifampin, tetracycline, and vancomycin. We found that bactericidal activity of vancomycin, fusidic acid, and mupirocin were good. In conclusion, this study provided useful information: 75% alcohol is the best disinfectant for wound dressing, 4% chlorohexidine gluconate(Microshield(R)) is useful for hand washing, and zepanon is useful for ward cleansing. Vancomycin-resistant Staphylococcus aureus was not found in our study.

BACKGROUND: In patients with chronic obstructive pulmonary disease(COPD), several factors have been associated with a poor prognosis. These include old age, low FEV, low diffusing capacity, high alveolar-arterial oxygen pressure difference, and finally cor pulmonale. This study was done to investigate in the ECG signs suggesting cor pulmonale were independent prognostic factors in patients with COPD. METHOD: We analyzed ECG, pulmonary function data and arterial blood gas values in 61 patients who were admitted through the emergency department with an acute exacerbation of COPD. The ECG signs reflecting cor pulmonale were right atrial overloading(RAO), right bundle branch block, right ventricular hypertrophy and low-voltage QRS. The 61 patients were divided into 2 groups, group I with no ECG signs(n=36) and group II with one or more ECG signs(n=25) suggesting cor pulmonale. RESULTS: Poor prognostic factors by univariate analysis were low FEV1, FEV1 % pred., VC% pred., DLco, DLco % pred., PaO2 and SaO2 high PaCO2 presence of ECG signs reflecting cor pulmonale, presence of mental status change, use of mechanical ventilator, and long tern use of glucocorticoid. A multivariate analysis indicated that age(risk ratio=1.13, 95% confidence interval 1.05~1.23), Dlco % pred. (risk ratio=0.97, 95% confidence interval 0.94~0.99), PaO2 (risk ratio=0.95, 95% confidence interval 0.90~0.99) and RAO(risk ratio=5.27, 95% confidence interval 1.40~19.85) were independent prognostic factors of survival. There was a significant difference in survival between the patients with and without RAO(p=0.038). The survival rates at 1, 2, and 5 years were 94.5%. 81.4%, and 50.0% in patients without RAO and 82.4%, 70.6%, and 27.5% in patients with RAO, respectively. CONCLUSION: These results suggest that the presence of ECG signs reflecting cor pulmonale is a predictor of survival and that RAO of these ECG signs is a significant independent predictor of survival in patients with COPD.

The occurence of multiple primary malignant tumor is cansidered infrequent and the primary adenocarcinoma of the duodenal bulb is a rare conditian. The autopsy incidence of duodenal adenocarcinoma is between 0.019 and 0.5%. The first documented case of duodenal carcinoma was described by Hamburger in 1746. Increased awareness of the condition, improvement in diagnostic technics and a more aggressive surgical approach have changed this disease from a postmortem curiosity to a condition that can be treated with satisfactory results. There are several reports on the high incidence of second additinoal cancer in patients with small intestinal cancer. Recently, we have experienced a case of primary duodenal bulb adenocarcinoma with early gastric cancer in a 68 year old male patient with complaints of epigastric pain, diarrhea and body weight loss. So we report the case of primary duodenal bulb adenocarcinoma combined with early gastric cancer with a brief review of literature.
