2.Expression of Fragile Histidine Triad (FHIT) Gene Product in the Uterine Cervical Carcinoma.
Korean Journal of Gynecologic Oncology and Colposcopy 1999;10(3):217-223
To investigate the involvement of expression of the Fragile Histidine Triad(FH1T) gene product in the process of carcinogenesis and progression in cervical carcinoma, we examined its expression by immunohistochemical method in 15 cervical invasive carcinomas, 10 low grade cervical intraepithelial neoplasias(CINs) and 30 high grade CINs(CMI and III). We detected expression of FHIT gene product in 4 of 15(27%) of invasive carcinomas, 3 of 10(30%) low grade CIN and 7 of 30(23%) of high grade CIN, while we detected expression of FHIT gene product in 28 of 45(62%) normal and metaplastic epithelium near the tumor. Thesc data indicate that loss of expression of FH1T gene product has some role in the early tumorigenesis of uterine cervical carcinoma, but not the consequence of the pregression of the tumor.

OBJECTIVE: In the previous study, we compiled the differentially expressed genes during early folliculogenesis.1 Objective of the present study was to identify downstream target genes of transcription factors (TFs) using bioinformatics for selecting the target TFs among the gene lists for further functional analysis. MATERIALS AND METHODS: By using bioinformatics tools, constituent domains were identified from database searches using Gene Ontology, MGI, and Entrez Gene. Downstream target proteins/genes of each TF were identified from database searches using TF database (TRANSFAC(R) 6.0) and eukaryotic promoter database (EPD). RESULTS: DNA binding and trans-activation domains of all TFs listed previously were identified, and the list of downstream target proteins/genes was obtained from searche of TF database and promoter database. Based on the known function of identified downstream genes and the domains, 3 (HNF4, PPARg, and TBX2) out of 26 TFs were selected for further functional analysis. The genes of wee1-like protein kinase and p21WAF1 (cdk inhibitor) were identified as potential downstream target genes of HNF4 and TBX2, respectively. PPARg, through protein-protein interaction with other protein partners, acts as a transcription regulator of genes of EGFR, p21WAF1, cycD1, p53, and VEGF. Among the selected 3 TFs, further study is in progress for HNF4 and TBX2, since wee1-like protein kinase and cdk inhibitor may involved in regulating maturation promoting factor (MPF) activity during early folliculogenesis. CONCLUSIONS: Approach used in the present study, in silico analysis of downstream target genes, was useful for analyzing list of TFs obtained from high-throughput cDNA microarray study. To verify its binding and functions of the selected TFs in early folliculogenesis, EMSA and further relevant characterizations are under investigation.

The Journal of the Korean Orthopaedic Association 1999;34(5):819-824
PURPOSE: To evaluate the treatment results of geriatric intertrochanteric fractures by using Asian-Pacific Gamma nails. MATERIALS AND METHODS: From June 1994 to June 1997, 58 cases of the intertrochanteric fractures were treated with Asian-Pacific Gamma nail, particularly compression hip screw fixation complications such as communited fracture involving lesser trochanter, transverse or reverse oblique intertrochanteric fracture. We evaluated the bone union time, neck-shaft angle, lag screw sliding by follow up radiographs, and studied complications and intraoperative cautions. RESULTS: The average age was 74.4 years old, the mean duration of follow-up was 17 months, the mean duration of bone union was 14.2 weeks, the average neck-shaft angle was postop. 133+/-2.78 degree and last follow-up was 129.5+/-3.37 degree, and the average lag screw sliding was 4.7+/-3.16 mm. Intraoperative complications were difficulty in distal drilling (posterior drilling) in 4 cases, fracture displacement by nail insertion in 3 cases, and postoperative complications were coxa vara in 13 cases, superior cutting out of lag screw with nonunion in 1 case and superficial infection in 1 case. The entry portal must be formed by awling. The fracture displacement when inserting nail could be prevented by proper reaming after inserting the C-shaped guide pin, and posterior drilling could be avoided by confirming the locking between target device and nail. CONCLUSIONS: We conclude that the Asian-Pacific Gamma nail could appropriately treat the osteoporotic, communited intertrochanteric fracture in elderly patients and we obtained satisfactory results.

Journal of the Korean Society of Coloproctology 1998;14(2):259-268
BACKGROUND: Various surgical techniques are used for the cure of hemorrhoid according to the extent of disease and severity of symptom. Purpose : We compared the postoperative clinical course after submucosal hemorrhoidectomy and ligation and excision of hemorrhoids. MATERIAL AND METHODS: Between February 1995 and May 1997, 221 patients underwent submucosal hemorrhoidectomy and 111 patients underwent ligation and excision of hemorrhoids at the Department of Surgery, Eulji General Hospital. We compared the hospital course and postoperative complications in two group. RESULTS: For submucosal hemorrhoidectomy group, mean operation time was 38 minutes, the improvement of postoperative pain, is based on no needs of analgesics after 48 hours of postoperation, was seen in 115 patients(52.0%), wound healing took 19.5 days in average, and mean hospital stay was 6.4 days. For ligation and excision group, these findings were mean operation time 21 minutes, the improvement of postoperative pain in 47 patients(42.3%), wound healing 25.4 days, and hospital stay 7.2 days. Postoperative complications such as skin tag, edema, and were more common in submucosal hemorrhoidectomy group. But anal fissure, stenosis were more frequent in ligation and excision group, although they did not occur later. CONCLUSION: We think that submucosal hemorrhoidectomy is a better method than ligation and excision in respect of postoperative course and complications.

Sjogren-Larsson Syndrome is a rare disorder chracterized by congenital icthyosis, spastic diplegia or tetraplegia and mental retardation. The inheritance is autosomal recessive, due to deficiency of alcohol dehydrogenase activity of fatty acid matabolism. We have experienced a case of Sjogren-Larsson Syndrome in a 16 month-old male children who have dried thick skin, developmental delay, and spastic diplegia. He also has glistening spot on macula area with irregular high voltage slow wave (2-3Hz) on electroencephalography. From Biopsy finding, Lamella ictyosis with acanthosis and hyperkeratosis in epithelium is shown. He was much improved clinically for skin lesion and developmental status with etretinate supplement. We report the case with brief review of related literatures.

Flavimonas oryzihabitans is a gram-negative, glucose non-fermentative bacillus, and is rarely reported as a pathogen in human. In recent years, reports of infection due to F. oryzihabitans, especially in immunocompromised patients with indwelling catheter or peritoneal Tenckhoff catheter have increased. We report two cases of F. oryzihabitans peritonitis in patients undergoing continuous ambulatory peritoneal dialysis (CAPD).

A rate com;lication of hysterectomy is complete prolapse and inversion of vagina. This can occur whether the hysterectomy was abdominal or vaginal and cystocele and/or enterocele is often associated with this condition. Traditionally, prolapse has been treated by surgery, the types of operation for prolapse are generally but not always, carried out through the vaginal rather than through the abdominal surgical route. We experienced five cases who had repair of posthysterectomy vaginal vault prolapse by transabdominal sacral colpopexy and report with brief review of literatures.
