Purpose: Paclitaxel, on systemic administration, is widely known to be effective in the treatment of bladder cancer. However, the intravesical use of paclitaxel has not been attempted because of its liposolubility and direct toxicity to the bladder mucosa. The purpose of this study was to evaluate the efficacy and toxicity of paclitaxel-loaded glyceryl monooleate (GMO) in the intravesical treatment of superficial bladder cancer, by enhancing its bioadhesiveness and bioavailability. Materials and Methods: 12 mice were divided into two groups, and bladder carcinomas induced by the addition of 0.05% BBN to their drinking water for 12 weeks. Group 1 received an intravesical instillation of 0.1ml GMO-paclitaxel-free buffer and Group 2 an intravesical instillation of 0.1ml GMO-paclitaxel. On day 21, the tumor incidence, bladder weight and toxicity were evaluated. Results: The incidence of cancer in groups 1 and 2 were 83 and 17%, respectively. The incidence of cancer was significantly reduced in group 2 compared to group 1 (p<0.05). There was a tendency for the average bladder weight in group 1 to be heavier than that in group 2, but there was no significant difference (p=0.375). There were no liver, kidney or bone marrow toxicities in either group. Conclusions: Intravesical GMO-paclitaxel therapy may have an inhibitory effect on the growth of superficial bladder cancer in a BBN-induced bladder cancer model; therefore, it could potentially be used in those patients showing little to no response to intravesical Bacillus Calmette- Guerin (BCG) or other anticancer drug therapies.

BACKGROUND: It is important to evaluate the patient presenting with non-traumatic chest pain in emergency department, and it is also difficult to classify appropriately. The purpose of this study is to predict probability of acute myocardial infarction(AMI) and assess the group for low probability of AMI that is target for observation-unit of chest pain in emergency department. METHODS: A prospective, clinical study was performed from March 1998 to August 1998 at the department of emergency medicine, Ewha Womans University Mokdong hospital. We classified high-probability group and low-probability group of AMI according to Goldman's algorithm and then compared with the final diagnosis. RESULTS: The study included 218 patients. 84 patients(39%) was the high-probability group and 134 patients(61%) was the low-probability group of AMI. As compared with final diagnosis, AMI was 47 patients(56%) among the high-probability group and 1 patient(0.7%) among the low-probability group. We observed sensitivity of 98%, specificity of 78% in predicting AMI. CONCLUSION: The classification according to Goldman's algorithm may be useful predictor of AMI and improve triage for emergency department patient with chest pain. It is also helpful for management of observation-unit of chest pain in emergency department.

BACKGROUND: We studied the antibiotic sensitivities to the causative microorganisms of acute simple urinary tract infection for recent 3 years. METHODS: We analyzed 112 microorganisms and their antibiotic sensitivities of the 104 patients who were admitted to or visited the Department of Urology, Catholic University St. Marys Hospital and had more than 10cfu/mL on urine culture from June 1996 to January 1999 retrospectively. RESULTS: The chance of gram negative and positive as causative microorganisms was 72.3% and 27.7% respectively. The most common pathogenic microorganisms were Escherichia coli (67.0%) followed by a-hemolytic streptococci, Entercoccus. In gram negative acute UTI, imipenem, sulperanzone showed relatively higher sensitivity, while cotrimoxazole, ampicillin showed relatively lower sensitivity. In gram positive, vancomycin, penicillin showed relatively higher sensitivity, while ampicillin, imipenem showed relatively lower sensitivity. CONCLUSIONS: We consider that gram negative microorganisms, especially E. coli, is the main cause of acute simple UTI. But, we should be concerned about the increase of gram positive organisms and other gram negative organisms besides E. coli. Regarding to the choice of adequate drug in the treatment of UTI, it is necessary to consider the change of pathologic microorganisms.

Uterine prolapse with pregnancy is rare condition. The overall incidence is 1/10000- 15000 deliveries. The complications from uterine prolapse range from minor cervical ulceration and infection to fetal death or uterine rupture. The fetal mortality was as high as 22% mainly due to prematurity, respiratory infection. The management of this condition is focused on preventing late occurrence of prolapse during pregnancy and continued reduction. We present a case of uterine prolapse in pregnancy with a brief review of the literature.

PURPOSE: This study was undertaken to investigate the serial alteration of collagen after resolution of the priapism in mechanically induced veno-occlusive priapism of rat model. METHODS: Sprague-Dawley male rats were used and divided into control and experimental groups (3, 6, 12, 24 and 48 hours according to the duration of ischemic time). The corpora were dissected out at 4 weeks after the relief of veno-occlusive condition, and then the collagen concentration was quantified. Type I, III and IV collagen were determined by immunohistochemical staining. RESULTS: The corporal collagen concentration showed significant increase in the groups of 12, 24, 48 hours of ischemic time. Types III collagen did not increased in intensity, but type I & IV collagen showed gradual increase in intensity according to the time interval of ischemic period. CONCLUSIONS: The irreversible collagen alteration in corpus cavernosum with veno-occlusive priapism occurred in case of 12 or more hours of ischemic time before resolution. Earlier non-surgical management is necessary for the patients to be safe from further cumulative damages either by recurrent episode or other kinds of disease.
