PURPOSE: The accuracy of CT in the detection of injuries of the solid visceral organ is well established, but the value of CT in diagnosing small bowel rupture after abdominal trauma is controversal. This study was conducted to ascertain CT finding of small bowel rupture result from abdominal trauma. MATERIALS AND METHODS: A retrospective analysis of preoperative abdominal CT findings in 40 patients was performed. Small bowel rupture was confirmed by surgery. Precontrast and postcontrast enhanced CT images were obtained in all patients. RESULTS: Diagnostic findings of small bowel rupture including pneumoperitoneum or retroperitoneal air, discontinuity of the bowel wall and extravasation of oral contrast materials were observed in 33 cases(83%). Intraperitoneal or retroperitoneal free air was seen in 31 cases(78%) and intraperitoneal or retroperitoneal free fluid collection was seen in 38 patients(95%). Small bowel wall was thickened in 31 cases(78%), bowel wall was enhanced in 12 cases(30%) and bowel wall discontinuity and extravasation of oral contrast material was seen in 5 cases, respectively. CONCLUSION: The CT scan is sensitive and effective modality for evaluation of small bowel rupture after abdominal trauma, because of high detectability of diagnostic and suggestive CT findings.

Obstruction on the urinary tract eventually results in damage to the kidneys and loss of function. The questions that concern the clinician are the degree of nephron loss in that kidney and the potential for recovery following the relief of obstruction. 99mTc DMSA accumulates in tubule cells and has been proposed as a marker of the tubular mass. The authors estimated the renal uptake ratio of 99mTc DMSA for the degree of nephron loss corresponding to duration of hydronephrosis following left ureteral ligation in 5 NewZealand white rabbits and the potential for recovery following percutaneous nephrostomy of hydronephrosis in 24 rabbits. While the renal uptake ratio of 99mTc DMSA of the kidney with unilateral hydronephrosis following ureteral ligation reduced dramatically within 24 hour, that of the opposite healthy kidney increased, and the total renal uptake ratio was same as normal functioning kidneys before ureteral ligation. Upon ureteral release, there was no evidence of definite recovery or impairment in the experimental kidneys for 5 days. The authors conclude that a combination of ureteral release and administration of some drugs such as renal vasodilator or diuretics is an appropriate treatment for the recovery of function in unilateral hydronephrosis.

3.Analysis of Chromosomal Aberrations in Lung Cancer Cell Line, NCI-H1373.
Korean Journal of Anatomy 2005;38(2):145-151
The cytogenetic analysis of recurring chromosomal aberrations play an important part to decide pathogenesis and prognosis of cancers. However, due to difficulties culturing tumor cells and complexity associated with the lesions, routine cytogenetic studies to analyze chromosomal imbalances are not sufficient. Comparative genomic hybridization (CGH) is a fluorescence in situ hybridization (FISH) technique to identify genomic imbalances in cancers, and array-CGH provides a method to measure the DNA copy-number changes quantitatively at an extremely high resolution and to map them directly onto the complete linear genome sequences. The purpose of this study was to confirm the utility of the CGH and array-CGH in analyzing chromosomal aberrations in lung cancer cell line, NCI-H1373, which was previously analyzed by karyotype analysis. The results of CGH and array-CGH in NCI-H1373 were similar to karyotype analysis. The array-CGH allowed us to pinpoint regions that were gained and lost. In this study, it was confirmed that CGH and array-CGH are an useful screening technique to analyze chromosomal aberrations in tumors.

4.Analysis of Chromosomal Aberrations in Head and Neck Squamous Cell Carcinoma Cell Lines using CGH.
Korean Journal of Anatomy 2006;39(6):515-522
The knowledge about chromosomal aberrations manifestated in cancer has been spotlighted recently, and these studies are important for the development of cancer diagnosis and evaluation of prognosis. Purpose of this study was examine the chromosomal aberrations which were related in the development and progression of HNSCC. In this study, chromosomal aberrationsin HNSCC cell line, SNU-1041, SNU-1066, SNU-1076, PCI-1, PCI-13, and PCI-50 were analyzed using CGH. As a results, gains on 9q32-q34, 16q22-q24, and 20q11.2-qter were observed in all six cell lines. Loss on 3p10-p14 was analyzed in five cell lines. Also, losses on 3p15-p23, 4q22-q27, 4q31.3-qter, and 18q21-q23 were observed in four cell lines. These data about the patterns of chromosomal aberrations in HNSCC cell lines would be a basic step for understanding more detailed genetic events in the carcinogenesis.

OBJECTIVES: The purpose of this study is to examine the moderating effect of social supports on the relationship between grief level and suicidal ideation of the elderly living alone. METHODS: We analyzed data from a questionnaire administered to subjects aged 65 years or older living alone for a 2017 community mental health project in Gyeongnam S city. To investigate the moderating effects of variables, we conducted a hierarchial regression analysis and confirmed the change R2. RESULTS: When adjusted for education and economic level, grief level had not a direct impact on suicidal ideation. And it was found that interdependent social support was moderating variables in the relationship of grief level and suicidal ideation of the elderly living alone. CONCLUSIONS: There is a need for appropriate programs that reduce suicidal ideation and therefore suicidal action. Moreover, it is especially necessary to enhance interdependent social supports.

The aim of this video is to present the procedural details of laparoscopic right hemicolectomy with aortocaval (infrarenal aortic bifurcation) lymphadenectomy, partial resection of the pelvic peritoneum (peritoneal carcinomatosis index, 3), and hyperthermic intraperitoneal chemotherapy in a patient who received neoadjuvant chemotherapy for stage IVc colorectal cancer. The total operation time was 290 minutes, and the patient was discharged on a postoperative day 13 without any complications. No postoperative complications occurred until postoperative day 60. The pathological stage of the tumor was determined to be T3N2bM1c. The pelvic peritoneal nodule was pathologically confirmed as a metastatic lesion. Among the 12 harvested aortocaval lymph nodes, 6 were metastatic lymph nodes. The minimally invasive approach was safe and feasible in this highly selected patient with colon cancer, aortocaval lymph nodes, and peritoneal metastases.

OBJECTIVE: Our purpose was to establish whether FHR recording tape and telemetry system at home interpreted by remote telemedicine link is comparable to interpretation at hospital in a high-risk patient population. Patients and METHODS: Twenty women whose pregnancy was suspected as high risk were entered to study. All pregnancies were at term(7 at 38th weeks, 7 at 39th weeks, 6 at 40th weeks). Remote FHR monitoring at hospital was made for consecutive 6 days, using FHR-telemetry system at home which already developed and used by authors from 1991. Patients recorded FHR sound using recording tape for 5 days. On the 5th day, real-time transmitting of FHR sound to the hospital was also done via telephone lines after recording of FHR sound. On the 6th day, FHR test(NST) was performed at hospital. The signal loss(%), baseline FHR(bpm), and FHR variability were compared using computerized FHR analysis system(HYFM-I) after re-play of 5-days recording tapes at hospital with real-time transmitting data and in-hospital FHR test results. RESULTS: The signal loss was highest with real-time transmiting data when comparing with in-hospital FHR analysis. No significant differences were observed among 5-days data of FHR recording tapes. CONCLUSIONS: Frequent antenatal visit of high-risk pregnancy patients were in diHuities of their pregnancy outcomes. And many rural areas of our country are without adequate access to basic maternity services. From this point of view, a fetal telemedicine service is needed, and in fact, technically and clinically feasible. Our demonstration suggests that such a service reduces the need for hospital visit of high risk pregnancy women. Further evaluation in a variety of clinical settings is now indicated, along with cost-benefit analysis.

Journal of the Korean Surgical Society 2008;75(4):262-267
PURPOSE: Intestinal duplication is a rare congenital anomaly that may be found anywhere from the mouth to the anus. The clinical presentation varies depending on the anatomic location or the size of the duplication, and the presence of the ectopic gastric tissue. The aim of this study was to analyze the clinical characteristics, the diagnostic and therapeutic methods, the location, the anatomic type and the associated anomalies of intestinal duplication. METHODS: We reviewed the medical record of eighteen patients with duplication of the alimentary tract and these patients had been treated at Kyungpook National University Hospital from July 1995 through October 2007. RESULTS: There were 9 boys and 9 girls. Their ages ranged from 3 days to 15 years. The most common symptom was abdominal pain. The duplicated segment acted as a leading point of intussusception in 3 cases. Two patients had melena. The duplications were cystic in fifteen cases and three others were tubular. In twelve cases, the lesions were located in the ileum; two other cases were located in the anal canal, one other was located in the in the transverse colon, another was located in the transverse and descending colon, one was located in the in the duodenum and one was located in the jejunum. Ultrasonography, computed tomography and barium enema were helpful as diagnostic tools. Three cases were diagnosed by prenatal ultrasonography. Associated anomalies were documented in four cases. All the patients underwent surgery. A duplicated lesion was lined with ectopic gastric mucosa in only one case. One patient still suffers from short bowel syndrome as a result of volvulus. CONCLUSION: The early operative treatment of intestinal duplication is safe and effective to prevent complications. In patients with intussusception, duplication should be considered as one of the causes of the leading point of intussusception.

PURPOSE: The analysis of recurring chromosome aberrations has become an integral part of the diagnostic and prognostic workup of many human cancers, and their molecular analyses have facilitated the identification of genes related to the pathogenesis of cancer But the technical limitation of conventional cytogenetic method makes unable us to characterize all recognizable chromosome rearrangements. The generation of chromosome region specific painting probe by PCR amplification of microdissected chromosomal DNA has proven extremely useful in identification of chromosomal derivation for marker chromosomes which are indeterminable by routine chromosome banding analysis. In this study we have constructed and analyzed the band-specific painting probe for unidentified marker chromosomes of renal cell carcinoma cell line, Caki-1 to determine the derivative chromosomes and the painting probes applied to CURC-II to compare the marker chromosomes. MATERIALS AND METHODS: Microdissection was performed on 9q+ and unidentified one of Caki-1, and chromosomal BNAs were amplified by PCR using topoisomerase I and T7 DNA polymerase. Fluorescent in situ hybridization was conducted with biotin labeled PCR products to normal, Caki-1 and CURC- II metaphase chromosomes. RESULTS: With this method, it was possible to construct the band-specific painting probes for markers and the probes hybridized specifically to the dissected regions and derivative chromosomes. The 9q+ and unidentified one were identified as t(9;17)(q34;q21) and t(15;20) respectively. The marker chromosomes - t(9;I 7), der(1 ;17)(ql0;q10), t(15;20), t(?;15), der(1 ;20), t(14;89) were examined same in Caki-1 and CURC-II. CONCLUSIONS: Thus this methodological advance significantly extends the limits of conventional cytogenetic analysis by enabling the analysis of unknown chromosome regions, and these painting probes can be applied to detect the similar marker chromosomes in renal cell carcinoma, and the probe pools for markeys may be used to identify the cancer-relevant genes.

Chromosomal abnormalities, which are valuable markers for diagnosis and prognosis of cancer, provide useful clues in characterizing cancer at molecular level. Gastric cancer is the major cause of cancer deaths in Asian countries, including Korea. Genetic changes during the progression and metastasis of gastric cancer remain unclear. Recently, technique of degenerate oligonucleotide primed (DOP) PCR-comparative genomic hybridization (CGH) permits genetic imbalances screening of the entire genome using only small amounts of tumor DNA. In non-metastatic gastric cancers the common sites of copy number increases were detected at 8q (64%), 4p12-q24 (64%), 5p13-q23 (64%), 13q21-q32 (64%), 6q11-q21 (55%), 7q(50%), 14q11.2-q21 (45%), 3q11-q13.3 (41%), and 2q23-q32 (41%). In metastatic gastric cancers, the frequent sites of gains were detected at 8p21-qter (60%), 5 (54%), 20 (42%), 6pter-q24 (51%), 1q21-qter (46%), 3p14-qter (46%), 22q (46%), and 4 (43%). Deletion or chromosomal loss was found to be less frequent in this study. The frequent sites of copy number decreases were detected at 1p34-pter (23%), 16q23-q24 (18%), and 19q13 (18%) in non-metastatic gastric cancers. In metastatic gastric cancers, chromosome losses were detected at X (37%), 1p33-pter (37%), and 16p (23%). The recurrent gains and losses of chromosomal regions identified in this study provide candidate regions that may contain oncogenes or tumor suppressor genes respectively involved in the tumorigenesis of gastric cancer.
