Recently, the bcl-2 and p53 protein have been recognized as important factors that is contributed to programmed cell death. The objective of this study was to evaluate the prognostic significance of bcl-2 and p53 protein expression in uterine cervical carcinoma. The expression of bcl-2 and p53 in 59 cases of uterine cervical carcinoma (stage IB to IIB) were surgically treated from January 1993 to June 1994. The expression of bcl-2 and p53 was examined by immunohistochemical method using formalin fixed paraffin embedded tissue specimens. The 48 cases were squamous cell carcinoma and 11 cases were adenocarcinoma. The results were as follows: 1. The expression rate of bcl-2 protein was 28.8%(17/59) and there was no significant correlaltion between the expression of bcl-2 protein and the clinicopathologic parameters (histologic type, grade, FIGO stage, cervical invasion depth, lymph node metastasis, parametrial invasion, tumor size, neoadjuvant chemotherapy response, recurrence, survival). 2. The expression rate of p53 protein was 32.2%(19/59) and there was no significant correlation between expression of p53 protein and the clinicopathologic parameters. 3. There was significant correlation between and expression of bcl-2 and p53 protein (P 0.05). In conclusion, bcl-2 and p53 protein are thought to be possible factors in the carcinogenesis of uterine cervical carcinoma and correlate with progression of it. But further study will be required to clarify the role of bcl-2 and p53 in carcinogenesis of the uterine cervix.

3.Clinical Significance of Calculated Prostate Cancer Volume as the Predictor of Pathologic Stage.
Korean Journal of Urology 2001;42(8):821-827
PURPOSE: Pathologic tumor volume is closely related with pathologic stage, pathologic Gleason grade, surgical margin status, and disease progression after radical prostatectomy. Therefore, an accurate assessment of prostate cancer volume is essential in prediction of pathologic stage. We evaluated that the calculated prostate cancer volume (cVca), a new clinical parameter, can predict for pathologic stage T3 in patients with clinical stage T1, 2 prostate cancer. MATERIALS AND METHODS: The cVca was determined in 26 men treated with radical prostatectomy in clinically localized prostate cancer (clinical stage T1, T2) based on pretreatment PSA, biopsy Gleason score, and prostate ultrasound volume. Logistic regression analysis evaluating the value of the PSA, biopsy Gleason score, cVca was performed. RESULTS: The mean of cVca was 4.07cm3 and the mean of cVca in localized and extensive prostate cancer was 1.77cm3 and 6.74cm3, respectively. The difference between the mean of cVca in localized and extensive prostate cancer was statistically significant (p<0.05). PSA and cVca were significant predictors of pathologic stage T3 disease in patients with clinical stage T1, T2 disease on univariate analysis, but cVca was only significant predictor on multivariate analysis. CONCLUSIONS: The cVca was more reliable parameter than PSA and Gleason score in predicting of pathologic stage T3 disease in patients with clinical stage T1 and T2 prostate cancer. Therefore, this new parameter can be used to select patients who are likely to have pathologic organ-confined disease.

BACKGROUND: Brief episode of coronary artery occlusion (i.e., ischemic preconditioning) makes the heart more resistant to injury from a subsequent ischemic insult. Although a great deal of effort has been made in studying ischemic preconditioning, the underlying mechanism of ischemic preconditioning and its effect on hypothermic insult has not been elucidated. This study was performed to see whether ischemic preconditioning protects against the depression of cardiac contractility induced by hypothermic cardioplegic arrest/reperfusion. And recently, adenosine was known to have some correlation with the mechanism of preconditioning. If so, does this effect remain after the blockade of adenosine receptor by 8-phenyl theophylline? METHOD: Twenty-four Sprague-Dawley rat weighed 250-350g were used and divided into three groups. Rat hearts were removed rapidly, and each isolated heart paced with a rate of 180/min was perused by modified Krebs-Hensleit buffer(KHB) solution on a Langendorff apparatus far an hour. After obtaining baseline data including left ventricular pressure(LVP), dp/dt, and coronary flow, cardiac arrest was induced by perfusion of 0degrees C crystalloid cardioplegic(St Thomas) solution. After that, all hearts were stored in the same St Thomas solution at salute temperature far 2 hours. In group I (control group), the hear was reperfused by KHB solution. In group II(preconditioning group), the heart was subjected to two 2-minute episode of global ischemia followed by 5 minute reperfusion with KHB solution(preconditioning) before cardiac arrest. In group III(phenyl theophylline group), the heart was subjected to preconditioning procedure and 8-phenyl theophylline at 10muM in concentration was added to KHB solution at time of reperfusion. Observing parameter was obtained in each group at 10, 20, 40 and 60 minutes after starting reperfusion and compared statistically by use of one way ANOVA test(STASTICA, release 4.5). P-value less than 0.05 was considered significant. RESULTS: Although depressed LVP, dp/dt, and Coronary flow were seen in all groups during the reperfusion period, the preconditioned group showed more effective recovery of LVP than that of the control group, especially at 10, 20 and 40 minutes(p<.05). We failed to demonstrate the difference between the phenyl theophylline group and the control group(p=NS). CONCLUSION: These results suggest that ischemic preconditioning has protective effect on recovery state of hypothermic cardioplegic arrest/reperfusion. Its protective effect was limited during early reperfusion stage and was blocked by adenosine blocker.

When an ectopic kidney is located on the opposite site from its ureteral insertion into the bladder, the condition is known as crossed ectopia. Ninety per cent of crossed ectopic kidneys are fused to the ipsilateral kidney. Herein we report a case of crossed renal ectopia with fusion in a 20 year old male.

High-pressure (HP) injection injury to the upper extremity often causes a very serious clinical problem, leading to poor outcomes, including amputation, so that a true surgical emergency is required. The outcomes can be improved with emergent wide surgical debridement. However the diagnosis of these injuries is often delayed due to underestimated evaluation at first appearance and lack of common knowledge of the seriousness of this injury. The type and pressure of the infecting material is an important factor in prognosis and organic solvents infected pressure injury can cause poor outcome and increased amputation rate. In this case, we report on reconstruction of HP oilbased paint injection injuries of the finger using T-shaped pedicles and multiple venous anastomoses. In this concept, arterial flow can be maintained by the reverse flow of distal anastomosis when there is difficulty with the proximal anastomosis. And venous flow can be preserved by deep and superficial vein anastomosis. This concept has various advantages including preserving patency of the pedicle in chronic vasculopathy or trauma cases and maintaining the arterial flow by the reverse flow of distal anastomosis and can improve the free flap survival by a two vascular anastomosis system.

In Albright's hereditary osteodystrophy (AHO) including the syndromes of pseudohypoparathyroidism (PHP) and pseudopseudohypoparathyroidism (PPHP), multiple areas of intracutaneous ossification are often encountered. The characteristic features are short stature, round face, short neck, obesity, cutaneous ossifications, and various skeletal anomalies including short metacarpal and metatarsal bones, curve of radius, and brachydactyly. The patient was a 10-month-old male infant. He presented slightly depressed erythematous hard plaques on the left upper chest and left thigh. We had taken biopsies from both skin lesions, confirming cutaneous ossification or bone formation. He also had the characteristic features of AHO. He had a history of admission due to patent ductus arteriosus and atrial septal defect. The laboratory results showed slightly decreased calcium, increased phosphorus and PTH levels. The patient received no specific corrective measures because his calcium and phosphorus levels were not far from normal values until newly developed similar skin lesions appeared.

PURPOSE: Acute urinary retention(AUR) is a serious outcome of benign prostatic hyperplasia(BPH). Although Foley indwelling catheterization is a standard treatment for the conservative management of AUR, we studied the success rate of in-and-out catheterization and the factors that favor a positive outcome of a trial treatment without using a catheter(TWOC). MATERIALS AND METHODS: We retrospectively reviewed the medical record of all 127 patients who admitted as emergency cases with primary AUR caused by BPH(from January 2002 to August 2005), and these patients underwent in-and-out catheterization or Foley indwelling catheterization and then they underwent TWOC 1 week later after the first treatment. The patients were divided into four groups: the success group(group I) or failure group(group II) that underwent in-and-out catheterization and the success group(group III) or failure group(group IV) that underwent TWOC. The factors that might influence the outcomes were assessed using logistic regression analysis and Student's t-test. RESULTS: Of the 62 patients who underwent in-and-out catheterization, 30 had no further episodes of AUR during 1-year follow up(group I) and the other patients had repeated episodes(group II). For the clinical parameters, only the retained urine volume was significantly difference between the two groups. The multivariate analysis revealed that the statistically significant influencing factor was urinary retention volume(p<0.01). CONCLUSIONS: For patients younger than 58 years old or the patients with a urinary retention volume less than 580ml, in-and-out catheterization may be considered as the first-line conservative management in preference to bothersome Foley indwelling catheterization.
