BACKGROUND: Alteration of a wide variety of cellular oncogerms have now been implieated in the causation of many human cancers. However, genetic studies have indicated that an abnormality of a single gene is usually insufficient to elicit the fug transformed phenotype and that two or more genetic leaions may be necessary for this to occur. OBJECT: The purpose of this study is to examine the possibity of oncogene interaction which might be involved in the pathogenesis of human skin tugois. METHODS: The expression of the epidermal growth factor rattor(EGFR), c-jun protein, c-fos protein and p53 protein was assessed in frozen and corresgoAhng paraffin-embedded sections of 37 separate skin lesions (6 actinic keratoses, 6 squamo is ell carcinomas and 25 basal cell carcinomas using immunohistochemistry. RESULTS: Substantial number of the p53 positive cases were negative for c-fos, in contrast to normal tissue, which was p53 negative and c-fos positive. The negative correlation between p53 and c-fos staining was statistically significant(P<0.005). CONCLUSION: Although p53 appeared to have lost its normal role of regulatory early S phase protein in some lesions, in others high levels of p53 were assocated with underexpression of c-fos, reflecting the diversity of c-fos oncogene and the possible down regulation of c-fos expression by high levels of p53 protein.

Because nonspecific colonic ulcer is an unusual condition and varies markedly in clinical presentation and course, preoperative clinical diagnosis of nonspecific colonic ulcer is very difficult, But now, preoperative clinical diagnosis can he made by advent of colonofiberscopy. And, it is very important to diagnose this disease early, because late diagnosis make a poor prognosis. We report a case of nonspecific colonic ulcer diagnosed by repeated colonofiberscopy and treated with surgery.

OBJECTIVE: To evaluate the usefulness of alendronate for prevention and treatment of postmenopausal osteoporosis this study was taken. METHODS: This prospective randomized clinical trial examined the effects of oral alendronate and HRT(conjugated estrogen plus medroxyprogesterone acetate), in combination and seperately, on BMD, biochemical markers of bone turnover in 79 women with low bone mass. Treatment included alendronate(10mg daily) plus HRT(group I, n=38), or HRT(group II, n=41) for 6 months. Bone density measurements were performed at months 0 and 6 at the lumbar spine. Biochemical markers of bone turnover were also measured every three months. RESULTS: Serum Osteocalcin decreased by 19.2% in group I and by 10.0% in group II at 3 months(p<0.05), and by 30.9% in group I and by 19.8% in group II at 6 months(p<0.05). Urinary deoxypyridinoline showed decrease of 19.75%(I) vs. 10.4%(II) at 3 months, 30.1%(I) vs. 20.7%(II) at 6 months, the difference was significant. Percent change of BMD measurements from baseline at 6 months in group I was 6.2% and in group II 0.6% on the lumbar spine(p<0.05). CONCLUSION: The treatment with alendronate is useful to postmenopausal women with osteoporosis by decreasing bone turnover markers, and by increasing the BMD.

Miller-Dieker Syndrome (MDS) is a contiguous gene deletion syndrome of chromosome 17p13.3, characterized by classical lissencephaly (lissencephaly type 1) and distinct facial features. Children with MDS present with severe developmental delay, epilepsy and feeding problems. The lissencephaly represents the severe end of the spectrum with generalized agyria, or agyria and some frontal pachy- gyria. Prenatal diagnosis is available and consists of fetal chromosomal analysis by karyotyping or fluorescence in situ hybridization (FISH), on chorion villus sampling or amniocentesis. Sonographic diagnosis in general cannot be accomplished earlier than late second trimester, when the characteristic cerebral anomalies can be noted. The progressive microcephaly and failure of development of both sulci and gyri are suggestive of lissencephaly. We report the case of a pregnant woman of 24 weeks gestation who presented with ventriculomegaly on antenatal sonography and hydrocephalus, and corpus callosum agenesis on fetal MRI, which was diagnosed as MDS by karyotyping and FISH on amniocentesis.

Spontaneous intra-abdominal hemorrhage from uterine leiomyomas is rarely encountered. We present a case of a 46-year-old who presented to the emergency room with acute abdominal pain as same as that has experienced for 5-6 times. On examination, the abdomen was diffusely tender, with rebound tenderness in the suprapubic area and in both iliac fossae. Pregnancy test was negative. She had an acute abdomen, dizziness, decreasing hematocrit, and a pelvic mass with free fluid in the pelvic cavity. On transvaginal sonography, 6.3 x 6.1 cm sized hyperechoic mass was visible beside the uterus and CDS. This mass had an ill-defined margin. Large amount of fluid was visible in the CDS and uterovesical pouch. Hemoperitoneum was confirmed by culdocentesis. Magnetic Resonance Imaging revealed a mass with cystic components, diffusely heterogeneous signal intensity and T1 high signal intensity in the left superolateral aspect of uterus. An moderate amount of fluid was found in the pelvic cavity. The patient underwent an exploratory laparotomy. A ruptured, pedunculated, cystic degenerated uterine myoma with active bleeding was found, as well as approximately a liter of free, blood-stained peritoneal fluid and blood-clots. Myomectomy was performed, followed by evacuation of the fluid and clots. The patient's postoperative course was uneventful. In conclusion, preoperative diagnosis of a perforated, uterine fibroid with spontaneous intra-abdominal hemorrhage is difficult; exploratory laparotomy is both diagnostic and therapeutic in this rare, life-threatening condition.

BACKGROUND: Bone mass changes in men is related to age, BMI, sex hormones and other factors. In prior studies, bone markers were negatively correlated with bone mineral density, free testosterone, and estrogen and was positively correlated with SHBG. In a study of sex hormones and bone markers in Korean men estradiol was negatively correlated with deoxypyridinoline. In this study, the relationship of testosterone, estradiol, calculated free testosterone, FEI and SHBG to bone turnover markers in adult men were investigated. METHODS: This was a cross-sectional study of 184 men who had undertaken a health screening program in one general hospital in Bundang from November, 2001 to February, 2003. We surveyed information concerning the past medical history, current medication, alcohol consumption amount per week and smoking amount by means of self questionnaire records. Serum total testosterone, estradiol, SHBG and osteocalcin, alkaline phosphatase were measured at a fasting state. Urine was tested for deoxypyridinoline. Free testosterone was calculated using albumin, SHBG, and total testosterone level. RESULTS: Deoxypyridinoline adjusted by age, BMI was negatively correlated with FEI (r=-0.17, P=0.020) and was positively correlated with smoking amount (r=0.20 P= 0.007). Osteocalcin was negatively correlated with calculated free testosterone and ethanol consumption amount (r=-0.186, P=.0.12, r=-0.186, P=0.012). Multiple regression analysis showed that the most powerful factor influencing deoxypyridinoline was smoking amount (R2= 0.046), followed by FEI, BMI, and the one influencing osteocalcin was BMI (R2=0.050), ethanol amount and calculated free testosterone. After adjusting for age, BMI, drinking amount and smoking amount FEI shown to be a predictor of deoxypyridinoline (beta=-0.08, p<0.01, R2=0.101). After adjusting for age, BMI, and drinking amount calculated free testosterone was shown to be a predictor of osteocalcin (beta=-0.570, P<0.01, R2=0.130) in multiple regression model. CONCLUSIONS: In adult men, FEI shown to be a predictor of deoxypyridinoline and calculated free testosterone to be a predictor of osteocalcin as an independent variable.

PURPOSE: Cytomegalovirus(CMV) infection still remains as a major cause of morbidity and mortality after stem cell transplantation. In this study, we analyzed the results of antigenemia-guided pre-emptive therapy among children with allogeneic hematopoietic stem cell transplantation to determine the incidence and risk factors associated with CMV antigenemia, and evaluated the efficacy of the CMV antigenemia based preemptive therapy. METHODS: We enrolled 213 pediatric patients following allogeneic hematopoietic stem cell transplantation(HSCT), at the Catholic HSCT center between October 1998 and December 2003. Pre-emptive ganciclovir was started when more than 5 CMV Ag-positive cells were detected in matched sibling HSCT, and when any Ag-positive cells were seen in unrelated allogenic HSCT. RESULTS: CMV antigenemia was observed in 88(41.3 percent) of 213 patients on median day 28(day 11-99). In univariated analysis, use of unrelated donors(other than siblings), age of recipient(more than 5 years at transplant) at transplantation, the presence of recipient CMV-IgG before transplantation, TBI-based conditioning regimen and the presence of acute GvHD(grade > or=II) were the risk factors for positive CMV antigenemia. In multivariate analysis, unrelated bone marrow transplantation, positive recipient CMV serology and acute GvHD(grade > or=II) were the independent risk factors for positive CMV antigenemia. CONCLUSION: Risk factors of CMV infection in children were CMV serostatus of the recipient, the source of stem cells, and acute graft-versus-host disease. The pre-emptive therapy based on CMV antigenemia was effective in the prevention of CMV disease.
