This is a clinical study on 113 patients, who were treated for parotid tumors at Chonnam National University Hospital over a period of 5 years from January 1996 to December 2000. The results were as follow, 1. The mean ages were 42.6 years old (12~73 years) for benign parotid tumor patients and 43.9 years old (2~74 years) for malignant patients. 2. The ratio of male to female was 1:2 in malignant parotid tumors, but there was no difference in sex distribution of benign tumor. 3. There was no difference in mean mass size and duration of illness between benign and nalignant tumor patients. 4. The combined use of fine needle aspiration biopsy and computed tomograph was common as the diagnostic method of parotid tumor 5. The parotid tumors were commonly located in the superficial lobe(69%). 6. The ratio of benign and malignant tumors was 4:1. The most common benign tumor was pleomorphic adenoma (72% of benign tumor), followed by Warthin's tumor and monomorphic adenoma. The most common malignant tumor was rnucoeplderrnoid carcinoma(45% of malignant tumor). followed by adenoid cystic carnoma. carcinoma ex pleomorphic adenoma, and adenocarcinoma. 7. The most common operations were superficial parotidectomy (72%) for benign parotid tumor and total parotidectomy (45%) for malignant tumor 8. The most common postoperative complication was temporary facial nerve weakness (82%), followed by Frey's syndrome (14%) and permanent facial palsy (4%). 9. Postoperative radiation therapy was done in 12 patients and the mean radiation dose was 5550±620cGy. 10. Of 113 cases. tumor recurrence developed in 12 cases (10%). These results suggest that the successful management of parotid gland tumors needs adequate surgical treatment on the basis of knowledge of parotid gland anatomy and preoperative diagnosis.

Background and Objectives : Digital rectal examination (DRE) and uroflowmetry have been usually together in the BPH management. The aim of this study was to determine whether DRE would affect uroflowmetry measurement. Materials and methods : A total of 80 male patients were included in this study. First uroflowmetry was done after DRE, second uroflowmetry was done without DRE. Third uroflowmetry was done after DRE, and fourth was done without DRE. Results : The mean Qmax on uroflowmetry after DRE was 15.2±8.7㎖/sec and 14.9±9.8㎖/sec. The mean Qmax on only uroflowmetry was 15.3±8.9㎖/sec and 15.4±8.4㎖/sec. There was statistically no difference between the mean Qmax(P> 0.05). And effect of digital rectal examination on uroflowmetry measurement with age was statistically no difference between the mean Qmax(P)0.05). Conclusions : We could not find and effect of DRE on uroflowmetry parameters, In this study, uroflowmetry test would be appropiate for recommending DRE before or after.

다제내성 임균감염

백승,임동훈 대한요로생식기감염학회 2013 Urogenital Tract Infection Vol.8 No.2

Gonorrhea, caused by Neisseria gonorrhoeae is the second most prevalent bacterial sexually transmitted infection. The disease causes serious reproductive compli-cations such as pelvic inflammatory disease, ectopic pregnancy, and infertility, and can facilitate human immunodeficiency virus transmission. Numerous anti-microbial agents have been used for the treatment of gonorrhea since sulfanilamides were introduced in 1936. Unfortunately, N. gonorrhoeae readily develops resistance to antimicrobial agents. Strains with decreased susceptibility to oral third generation cephalosporin (cefixime) are currently emerging. The US Centers for Disease Control and Prevention (CDC) no longer recommends cefixime at any dose as a first-line regimen for treatment of gonococcal infections, but recommends combination therapy with ceftriaxone 250 mg intramuscularly and either azithromycin 1 g orally as a single dose or doxycycline 100 mg orally twice daily for 7 days as the most reliably effective treatment for uncomplicated gonorrhea.

방광에 발생한 Malakoplakia

Malakoplakia is a rare chronic granulomatous disease, which was originally described in the urinary bladder, but can involve many other organs and soft tissues. Malakoplakia is often associated with immunosuppression or immunodeficiency and is believed to be caused by an alternation in the bacterial phagocytic system. Histologically, the presence of Michaelis-Gutmann bodies is pathognomonic. We report on a case of malakoplakia of the bladder in a 62-year-old female.

Purpose: To assess the efficacy, morbidity and patient recovery of hand- assisted laparoscopic donor nephrectomy(HALDN), we compared our initial experience with HALDN to that of the standard open donor nephrectomy(ODN). Materials and Methods: Between March 2002 and March 2004, one surgeon performed 18 cases of HALDN and 9 cases of ODN at our institution. Operative outcome were reviewed, including operative time, warm ischemic time, blood loss, time to oral intake, length of hospital stay, postoperative analgesic requirement, complications and graft function. Results: The mean operative time was 232 minutes and 192 minutes(p<0.01), and the mean warm ischemic time was 185 seconds and 168 seconds (p=0.28) for HALDNs and ODNs, respectively. The mean blood loss and time to oral intake were similar. The mean hospital stay was 4.3 days and 8.7 days(p<0.01), and the mean analgesic dose was 80mg of piroxicam and 260mg of piroxicam(p<0.01) for HALDNs and ODNs, respectively. No patient required open conversion. Complications occurred in 2 cases in HALDNs and in 1 case in ODNs. All donated kidneys were transplanted with immediate good function. The recipients' serum creatinine level at 1, 2, and 3 years after transplantation showed no significant difference between the two groups. Conclusions: HALDN is technically feasible and appears to be a safe and effective surgical method. HALDN provides the donor with faster convalescence, while maintaining a healthy renal allograft function for the recipient.

Trametes versicolor showed the ability of degrading synthetic dyes such as congo red (CR) and methylene blue (MB) in solid and liquid culture conditions. The T. versicolor strains isolated in Korea degraded MB more efficiently than CR, differently most of other white mushrooms known to have difficulties in degrading MB than other dyes. Thus the Koren strains of T. versicolor showed the commercial potential to be used for cleaning dye-contaminated region without any patent-related problem. The main enzyme responsible for dye deradation was laccase. The manganese peroxidase (MnP) was also detected and supposed to be involved in the degradation process of synthetic dyes. However, no lignin peroxidase (LiP) was detected from degradation process, indicating LiP is not the enzyme T. versicolor use to degrade CR and MB.

카릴 처칠의 『최상의 여성들』에 나타난 성공과 모성

백승은,손석주 현대영미어문학회 2019 현대영미어문학 Vol.37 No.4

. This paper examines the dynamics of women’s success and motherhood in Caryl Churchill’s Top Girls. It compares and analyzes the success and motherhood of two female main characters: Marlene who rejects motherhood and leaves her family behind and Joyce, who raises Marlene’s daughter, Angie and cherishes her/the maternal role. Top Girls shows that there may be mothers who reject motherhood and value success more than parenting, and that this cannot be unconditionally criticized. Churchill criticizes a society in which women are forced to choose between motherhood and career through Marlene and Joyce. Likewise, Top Girls shows that women who are not biological mothers can have maternal instincts and be mothers. Churchill's play emphasizes not only the economic independence and success of women but also the positive value of motherhood that has been ignored and undervalued. Thus, this paper shows how the altruism of motherhood and sisterhood can change individuals and society, rather than oppressing and discriminating other women. (Dong-A University)
