An immunohistochemical stain for p53 tumor suppressor gene product was performed in 59 primary lung cancers to study the relation between its expression and type of the tumor, degree of tumor differentiation,clinical stage and smoking. The results were as follows: 1. The expression of mutant p53 protein was noted in 28 of 59 cases(47.5%) of primary lung cancers. The p53 protein was expressed in 21 of 35(60%) squamous cell carcinomas, in 6 of 21(28.6%) adenocarcinomas, and 1 of 1(100%) small cell carcinoma. There was a significant difference in expression of p53 among the different histologic types of lung cancer(p<0.05). 2. The incidence of p53 protein expression did not correlate with the degree of tumor cell differentiation or the clinical stage of lung carcinoma(p>0.05). 3. The incidence of p53 protein expression was higher in smokers(current: 75%, former: 46.2%) than in non-smokers(5.6%) and was increased in direct proportion to the pack years. There was a statistically significant correlation between p53 expression and smoking(p<0.05). The mutation of p53 gene may often be an early event in the development of lung cancer and it is suggested that the smoking known as a risk factor for the development of the lung cancer may be associated with the transformation of p53 tumor suppressor gene into mutant p53 gene or oncogene.

BACKGROUND: Otitis media with effusion(OME) is a very common disease in pediatric age. However, a few literatures on epidemiologic study of otitis media with effusion are available in Korea due to the great variability of its diagnostic criteria and clinical features. The aim of this study is to provide the estimate of silent otitis media prevalence for preschool age. METHODS: The study population includes 329 children enrolled in 6 kindergartens in Kunsan city from April 1 to 10, 1995. Silent otitis media was diagnosed with otoscopy, pneumatic otoscopy and impedance audiometry by DANAC 40 model impedance audiometer from DANA JAPAN Co. RESULTS: The prevalence of silent otitis media with effusion was 14.5% and peak at 6 years of age(17.8%).The prevalence of silent otitis media with effusion according to sex were 11.8% in boys group, 17.9% in girls group. Nine cases(11.8%) involved bilaterally. Forty three cases(89.6 %) were asymptomatic cases. CONCLUSIONS: Among 329 preschool children, the prevalence of silent otitis media with effusion was 14.5%. The prevalence by sex showed slightly higher in girls group than boys group. OME involved unilateral site mostly and subjective symptoms were rare.

OBJECTIVE: This study was conducted to investigate the effect of vitrification on the implantation the pregnancy of human blastocysts. METHOD: The transfer of the frozen-thawed blastocysts by the slow freezing or vitrification was performed between January 1998 and July 1999. The zygotes derives from IVF were cocultured with cumulus cells in YS medium containing 20% hFF for 5days. Two or three of the best balstocysts produced on day 5 were transferred into the uterus, and then supernumerary blastocysts were randomly divided into two groups. One was frozen by slow freezing and the other was frozen by vitrification method. The slow freezing procedure was performed in two steps (5% glycerol and 9% glycerol + 0.2 M sucrose for 10 min, respectively) using programmed freezer (-2degrees C/min to -7degrees C, 0.3degrees C and plunged into LN2). The blastocysts frozen by slow freezing were thawed at 36degrees C then removed glycerol in 7 steps. The vitrification procedure was performed in three steps (10% glycerol for 5 min, 10% glycerol + 20% ethylene glycol for 5 min, 25% glycerol + 25% ethylene glycol and directly LN2 within 1 min). The blastocysts frozen by vitrification were thawed at 20degrees C water then removed cryoprotectant in 3 steps. In each group, thawed blastocysts were cocultured with cumulus cells in YS medium containing 20% hFF for 18h and transferred into the uterus. The implantation rate was evaluated per transferred blastocysts and the pregnancy rate was evaluated per transfers. RESULTS: The survival rate of vitrified group (74.5%) was higher than slow freezing group (68.0%), but not significant. When 98 thawed blastocysts of vitrification were transferred in 40 cycles, 19 pregnancies (clinical pregnancy rate; 47.5%) were established. One miscarriage occurred in the eighth week of pregnancy (ongoing pregnancy rate; 45.0%). 7 pregnancies were ongoing, 11 pregnancies went to term, and 16 healthy infants were born. The Implantation rate was 31.6%. These results were higher than those obtained by the slow freezing (clinical pregnancy rate; 40.3%, ongoing pregnancy rate; 32.5% and implantation rate; 25.3%), but not significant. CONCLUSION: Vitrification is a simple, quick and economical method when compared to slow freezing. It will be chosen as a good method of human embryo freezing in IVF-ET programs.

PURPOSE: While numerous methods have been introduced to repair hypospadias, no single method is effective for repairing all hypospadias. We reviewed our experience of hypospadias repair to determine the best surgical method and the efficacy of the treatment modality. MATERIALS AND METHODS: We reviewed the hospital charts of 32 patients who had undergone hypospadias surgery from January 1993 to January 2002. Group 1 included patients who were operated on before 1998 and group 2 had those who had operations after 1998 with only the TIP(tubularized incised plate) method. The surgical procedures that were performed on the patients were onlay island flap(6), Mathieu(2), Hodgson's type III(2), Mustard(2), TIP(14), Transverse island flap(5), and Thiersch-Duplay(1). The mean operative time, mean hospital days, mean duration of catheter drainge, and complication rates of the two groups were compared. RESULTS: In group 2, operation time was reduced(142.9+/-69.4 versus 172.5+/-93.4 min)(p<0.05), but the two groups showed no significant differences in mean hospital days(11.9+/-2.8 days. versus 12.3+/-1.6 days) and mean duration of catheter drainge (9.8+/-24 versus 10.5+/-3.6 days). In group 1 and group 2, complication rates were 67% (12 of 18) and 14%(2 of 14), respectively(p<0.05). CONCLUSIONS: Our data show shorter operative time and lower complication rates using the TIP method for various types of hypospadias. Therefore, the TIP method seems to be a safe method of surgery for any type of hypospadias.

PURPOSE: An autologous dermal fat graft has several advantages, over other viable or synthetic sling materials, in expenditure, postoperative complication and biocompatibility of the host. We investigated the success rate and risk factors of a pubovaginal sling, using an autologous dermal fat graft, in female stress urinary incontinence. MATERIALS AND METHODS: We retrospectively analyzed the medical records of 30 women that underwent a pubovaginal sling, using a dermal fat graft. The preoperative evaluations included: age, Stamey grade, Blaivas type, urodynamic study and previous pelvic operation history. We observed the postoperative results using questionnaire research during the follow-up (cured: no urine leakage and satisfactory, improved: urine leak< or =4 times/week and satisfactory, failed: urine leakage>4 times/week or unsatisfactory). The risk factors affecting the postoperative outcomes and complications were also analyzed. RESULTS: The success rate was 90.0% (success rate was calculated by cured rate plus improved rate, cured rate: 53.3%, improved rate: 36.7%), with the follow-up periods ranging from 6 to 24 months. A wound infection, requiring hospitalization, developed in one patient, but no other significant complications related to dermal graft were noted. Within the preoperative evaluations, the Blaivas type and a previous pelvic operation history were statistically related to the success rate (p<0.05). CONCLUSIONS: The Blaivas type and previous pelvic operation history are meaningful factors for predicting the success rate. The use of a dermal fat graft might be beneficial in the treatment of stress urinary incontinence in terms of its cost and success rate. However, a lower abdominal scar, of more than 5cm in length, and postoperative infections remain in some patients. Therefore it might be necessary to find another useful material for to treat female stress urinary incontinence.

PURPOSE: Although percutaneous aspiration and sclerotherapy is a simple, noninvasive and cost-effective therapy for symptomatic renal cysts, the recurrence rate is high. Recently, a laparoscopy has been attempted on symptomatic renal cysts. To assess the clinical efficacy and safety of the laparoscopic cyst marsupialization, the clinical characteristics and operative parameters were evaluated, and compared with the results of sclerotherapy. MATERIALS AND METHODS: Between November 1993 and February 2003, 71 patients with symptomatic simple renal cysts were treated with either laparoscopic marsupialization or sclerotherapy. Respectively, 26 of 31 laparoscopy patients and 27 of 40 sclerotherapy patients were followed-up over a 2 months period and included in this study. The laparoscopic marsupialization was accomplished with either transperitoneal (15 patients) or retroperitoneal approaches (11). The sclerotherapy was composed of percutaneous aspiration followed by an injection of 99% ethanol. RESULTS: The clinical characteristics, including cyst size, location and laterality, were no different in either group. The mean follow-up durations were 19.7 and 18.1 months in laparoscopy and sclerotherapy groups, respectively. Comparing the laparoscopy with the sclerotherapy group, the operation time (106.2 vs. 15.3 min.), hospital stay (7.8 vs. 4.6 days) and complication rate (23.1 vs. 3.7%) were significantly decreased in the sclerotherapy group. However, the success rate (96.2 vs. 77.8%) was significantly increased in the laparoscopy group. With either the transperitoneal or retroperitoneal approaches in the laparoscopy group, there was no statistical difference in the operative time, hospital stay and complication and success rates. CONCLUSIONS: For a symptomatic renal cyst, laparoscopic marsupialization is an effective therapy, with a high success rate on the long-term follow-up. The clinical results, according to the approach method, were not different for the transperitoneal and retroperitoneal approaches.

BACKGROUND: Anticonvulsants and antidepressants are adjuvant analgesic drugs that are used widely for treating chronic neuropathic pain syndromes. The combined analgesic effect of gabapentin and milnacipran was investigated with a rat neuropathic pain model. METHODS: The rat neuropathic pain model was made by ligating the spinal nerves (L5 and L6). An intrathecal catheter was inserted into the subarachnoid space. Tactile allodynia was tested with the up-down method using von Frey hair. We determined the antiallodynic effect of intraperitoneal (I.P.) and intrathecal (I.T.) gabapentin. The combined effect of I.P. gabapentin (50 mg/kg) and milnacipran (0, 10 and 30 mg/kg) was investigated. RESULTS: Intraperitoneal and intrathecal administration of gabapentin increased the threshold for tactile allodynia (the ED50 was 60.6 mg/kg and 45.5microng, respectively). Co-administration of I.P. milnacipran increased the antiallodynic effect of I.P. gabapentin in a dose-dependent fashion. CONCLUSION: The combined administration of milnacipran and gabapentin may increase the total analgesic effect during treatment of neuropathic pain.
