A clinical evaluation has been undertaken of 41 patients with urethral stricture who have been treated with visual urethrotomy in the Department of Urology, Seoul National University Hospital during 3 years periods from 1983 to 1985. The over all success rate was 54%. The results were unrelated to the sites of the lesion, the causes of the stricture and the durations of the catheter drainage. However, the results of the obliterated strictures (12.5%) are more poor than the non-obliterated strictures (64%), and patients with nonobliterated stricture less than 2cm long had the best results (22%). The overall morbidity rate was 20%, six cases of false way, one case of incontinence, one case of penile hematoma. Twenty seven cases were followed up over 6 months and its success rate showed 44.4%.

S.I. of TCSA PCH (group B) and musk ambrette PCH (group D) were respectively g3 49% and 75.00 S.I. of group A and B, which were only challenged with TCSA and musk ambrette respectively without prior sensitization, were 33, 33% and 27. 78%. These data indicated the TCSA PCH (group B) was experimentally produced in guinea pigs when it compared to musk ambrette PCH (group D) and controls (group A and C) (Table 1). However, S.I. of TCSA PCH was somewhat lower than index of musk ambrette PCH.

Subperiosteal Ganglion is a rare cystic lession, although ganglions are frequently found in close proximities to joints and tendon sheaths. It is characterized by a thin-walled cyst containing tenacious mucoid fluid and by the pedicle attached to periosteum. This report describes a middle-aged man with a subperiosteal ganglion which occured beneath the periosteam of the tibia. Presenting symptoms were pain and circumscribed swelling over the anteromedial aspect of the right proximal tibia.

Epstein-Barr virus (EBV) latent infection transforms B lymphocytes into proliferating lymphoblastoid cell lines (LCLs). EBV latent infection membrane protein 1 (LMP1) is required for EBV-mediated B lymphocyte transformation, and LMP1-induced NF-kappaB activation is essential for LCL survival. Previously, it was reported that the level of reactive oxygen species (ROS) and the expression of apoptosis signal-regulating kinase 1 (ASK1) are elevated in EBV-positive Burkitt's lymphoma (BL) cells, the potential role of ASK1 in LMP1-induced NF-kappaB activation was thus investigated in this study. In EBV-positive BL cells, ASK1 was highly expressed and activated. In addition, TRAF6-ASK1 interaction was significantly increased in EBV-positive BL cells. Interestingly, the expression of LMP1 alone facilitated ASK1 activation. The expression of a dominant negative ASK1 mutant (ASK1KM) strongly blocked LMP1-induced NF-kappaB activation. Furthermore, LMP1-induced NF-kappaB activation was significantly reduced in ASK1 knock out (ASK1-/-) mouse embryonic fibroblasts (MEFs). Taken together, these results demonstrate that ASK1 is activated by LMP1 and is critical for LMP1-induced NF-kappaB activation.

OBJECTIVES: This study was conducted to investigate Chinese female marriage immigrants' dietary life after immigration to Korea, focusing on comparison between Han-Chinese (traditional Chinese) and Korean-Chinese (Chinese of Korean descent). METHODS: An in-person survey was conducted with women married to Korean men, having one child or more aged 1-6 years old, and having resided in Korea for at least one year before the survey. The data were collected from the 309 respondents comprising 151 Han-Chinese and 158 Korean-Chinese in the summer of 2013. RESULTS: Overall, there was no significant difference in dietary practice, dietary acculturation, dietary behavior, dietary habits, and food intake between the Han-Chinese and the Korean-Chinese respondents. Over 50% of the respondents ate Korean food every day. The overall level of dietary acculturation was about 3.5 out of 5 points. The average score of healthy dietary behavior was a little bit higher than 3 out of 5 points. Approximately 3/4 of the respondents showed increasing frequency of eating out. The respondents reporting increase food diversity were over 70%. Decreased frequency of skipping meal was about 60% of the respondents. Over 50% of the respondents showed increasing consumption of Kimchi, vegetables, fruit, and meat. CONCLUSIONS: Dietary life of Korean-Chinese female marriage immigrants was similar to that of Han-Chinese female marriage immigrants after immigration to Korea. The results from this study suggest that not only Han-Chinese but also Korean-Chinese should be targeted in various diet-related acculturation support programs as important multicultural populations in Korea.

PURPOSE: To investigate the effect of gas tamponade with vitrectomy for lamellar macular hole. METHODS: This study included 18 eyes of 18 patients with lamellar macular hole who reported visual acuity loss or distorted vision. All patients underwent vitrectomy, epiretinal membrane removal and internal limiting membrane peeling. Intravitreal gas tamponade was performed only in 8 eyes of 8 patients. The patients were divided into 2 groups: 8 eyes in the gas tamponade with vitrectomy group and 10 eyes that did not receive gas tamponade in the control group. The best-corrected visual acuity (BCVA) and appearance based on optical coherence tomography (OCT) were obtained retrospectively. RESULTS: Epiretinal membranes were observed in all cases. Average visual acuity of the gas tamponade group improved from log MAR 0.50 +/- 0.24 to log MAR 0.25 +/- 0.14 (p = 0.041). In the control group, average visual acuity improved from log MAR 0.53 +/- 0.36 to log MAR 0.32 +/- 0.28 (p = 0.041), however, no significant difference was observed in visual acuity between the 2 groups (p = 0.584). Anatomical closure or normalized foveal contour after surgery was confirmed in 6 of 8 eyes in the gas tamponade group and in 7 of 10 eyes in the control group. No significant difference between the 2 groups was observed (p = 1.00). CONCLUSIONS: Gas tamponade combined with vitrectomy for lamellar macular hole did not affect postoperative anatomical and functional recovery.

Lichen planus is a common, usually intensely pruritic papulosquamous dermatosis with unknown etiology, which may involve the skin, mucous membranes, hair follicles, and nails. Its lesions are usually a localized form but generalized ones are an unusual presentation of lichen planus. We report herein three cases of generalized lichen planus in one male and two female patients, which was diagnosed on clinical and histopathological examinations in all cases.

Lichen nitidus, characterized by its typical clinical and histopathologic findings, is an uncomrnon chronic dermatosis of unknowned etiology. The distribution of this disease is most often localized, but in some cases it may becorne generalized. Some authors suggested that lichen nitidus is a variant of lichen planus in terms of its coincidence, ultrastructural and immunophenot,ypic studies. We report herein a case of lichen nitidus which presents dark brown linear, grouped, or confluent papules on the face, cheat, and upper extremities, accompanying with the histopathologic findings of pigmentary incontirence in the portion of claw clutching a ball appearance. This report suggests that lichen nitidus shows hyperpigmentation clinically and could be one of the dermatoses which exhibit pigmentavy incontinence in a histopathologic study.

OBJECTIVE: Peripartum emergency cesarean hysterectomy of 28 cases at our hospital for 10years were reviewed that the clinical indication, history, and annual incidence change. METHODS: A retrospective descriptive analysis from January, 1988 to December, 1997 was carried out. RESULTS: There were 28 cases of emergency cesarean hysterectomy identified during this period among total 24, 689 deliveries. The annual incidence of emergency cesarean hysterectomy was significantly declined statistically(p<0.005). Cesarean hysterectomy was performed in 20 of 6, 671 cesarean section(0.30%) and in 8 of 18, 018 vaginal deliveries(0.04%), so more frequently after cesarean section than vaginal delivery. The cesarean hysterectomy rate was more frequent in multiparous women(0, 22%) than in nulliparous women(0, 02%). The most common indication of cesarean hysterectomy was 13 cases of uterine atony(46%), followed by 5 cases uterine rupture(18%), 5 cases of placenta previa with placenta accreta(18%), 3 cases of placenta previa(11%), 2 cases of uterine myoma(7%). No significant difference in length of operating time, amount of blood loss and operative complications were found between total abdominal hysterectomy and subtotal hysterectomy. The all patient who had cesarean hysterectomy recieved from 1200ml to 15840ml of blood transfusion with a mean of 3673ml. In aspect of fetal outcome, 3 cases of FDIU(Fetal death in utero) in uterine rupture and 1 case of stillbirth in preterm were found. The maternal complications were wound disruption, DIC, wound hematoma, ureter injury, vaginal stump bleeding, UTI(Urinary tract infection) and retroperitoneal bleeding, CONCLUSION: We conclude that the incidence of emergency cesarean hysterectomy declined with prediction of antenatal risk factor, preparing of sufficient fresh blood, prophylactic antibiotics, vigorous uterotonics and close observation after delivery.
