PURPOSE: To evaluate the parameters affecting vaulting and correlation between preoperative crystalline lens rise and vaulting after implantable collamer lense (ICL) implantation. METHODS: A total of 53 eyes of 34 patients who underwent ICL implantation were examined retrospectively. White-to-white (WTW) and anterior chamber depth (ACD) were obtained from scanning topography (ORB scan) before surgery. Preoperative crystalline lens rise (CLR) and vaulting at 6 months after ICL implantation were measured using anterior segment optic coherence tomography (AS-OCT). Multiple regression analysis was performed to evaluate the factors affecting central vaulting. RESULTS: The mean preoperative crystalline lens rise was -120 +/- 219 microm, and mean central vaulting 6 months after surgery was 544 +/- 175 microm. Preoperative SE, WTW, ACD, and CLR were significantly correlated with vaulting at 6 months after surgery. With the use of meaningful variables, multiple regression analysis showed that CLR, WTW, ACD and SE, in that order of influence, had significant effects on vaulting and the multiple regression equation was obtained as follows: Vaulting (microm) = (160.913 x ACD (mm)) + (170.134 x WTW (mm)) + (-0.338 x CLR (microm)) + (-23.783 x SE (D)) - 2250.184. CONCLUSIONS: CLR had a stronger influence on vaulting after ICL implantation than the previously proven parameters: WTW, ACD, and SE. In addition to WTW, ACD and SE, CLR should also be considered a new criterion for estimating vaulting after ICL implantation.

OBJECTIVE: Cervical cancer has long been linked to the sexually transmitted human papillomavirus (HPV), and the oncoproteins E6 and E7 disrupt the functions of tumour suppressor genes, resulting in genetic alteration. It was shown that loss of heterozygosity at 6p is a common genetic alteration in cervical cancer. However, the molecular genetics of cancer have only recently been understood, and for the development of cervical cancer additional genetic alterations in host cell genes are required. The present study has identified the differential changes of the cervical cancer-associated genetic alterations by a genome-wide array based comparative genomic hybridization (array-CGH). METHODS: We analyzed 15 cases of cervical cancer from St. Mary's hospital of The paraffin-fixed tissue samples were microdissected under microscope and DNA was extracted by the procedures of proteinase K digestion and chloroform extraction. Array-based CGH and genomic PCR were carried out with statistical analyses such as hierarchical clustering and Gene Ontology. The BAC array used in this study consisted of 1,440 human BACs, the space among the clones were approximately 2.08 megabase (Macrogen, Seoul, Korea). RESULTS: All of 15 cases of cervical cancer showed specific gains and losses. The analysis limit of average gains and losses was 53%. A significant positive correlation was found between 1p36.32, 3p14.2, 3q27.1, 7p21.1, 8q24.3 and 11q13.1 changes through the cervical carcinogenesis. The high-level of gain regions, BAC clones encoded GSDMDC1, RECQL4, TP73, ABCF3, ALG3, HDAC9, ESRRA and RPS6KA4 genes. Frequently gained BAC clones encoded genes were PRSS8, FUS, COL18A1, PCOLN3, MAFG and ASPSCR1. The genes encoded by frequently lost BAC clones were PTPRG, GRM7, ZDHHC3, EXOSC7, LRP1B and NR3C2. Also, hierarchical clustering of the expression data readily distinguished genomic alterations in cervical cancer. A subset of cellular processes from each gene was clustered by Gene Ontology database. CONCLUSION: Using Array-CGH, genomic alterations related to cervical cancer were identified to determine whether induction of chromosomal imbalances occurs prior to carcinogenesis. The high resolution of array-CGH combined with human genome database would give a chance to find out possible target genes present in the gained or lost clones.

OBJECTIVE: Previous studies were showed that adenoassocited virus (AAV) infection was had negative effects on human papillomavirus (HPV) infection and that the cervical cancer cell growth is inhibited by AAV infection. We detected of AAV 2 and high-risk HPV infection and researched correlation with AAV 2 and HPV in cervical cell. METHODS: Cell of normal cervix (49 persons), infected HPV cervix (45 persons), cervical intraepithelial neoplasm (CIN) I (31 persons), II (20 persons), III (35 persons), and invasive cancer (30 persons) were investigated by PCR using AAV-2 and HPV type 16 and 18 specific primers. RESULTS: AAV 2 was detected in 8 out of 49 normal cervix (16.3%), 2 out of 45 infected HPV cervix (4.4%), 3 out of 31 CIN I (9.7%), 4 out of 20 CIN II (20%), 8 out of 35 CIN III (22.8%), and 3 out of 30 invasive cervical cancer cases (30%). However, HPV 16 was detected in 5 out of 49 normal cervix (10.2%), 20 out of 45 infected HPV cervix (44.4%), 13 out of 31 CIN I (42%), 11 out of 20 CIN II (55%), 19 out of 35 CIN III (54.3%), and 21 out of 30 invasive cervical cancer cases (70%). HPV 18 was detected in 6 out of 49 normal cervix (12.2%), 18 out of 45 infected HPV cervix (40%), 16 out of 31 CIN I (51.6%), 10 out of 20 CIN II (50%), 22 out of 35 CIN III (62.8%), and 13 out of 30 invasive cervical cancer cases (43.3%). CONCLUSION: AAV 2 was detected in normal and infected HPV cervix, CIN (I, II, III) and invasive cervical cancer. As compared to normal, CIN I and CIN II, suggesting significant correlation between AAV 2 and HPV type 16. Further, researches continue to be done relationship to AAV 2 and HPV infection in cervix.

PURPOSE: The tumor suppressor gene, p53, has been established as an essential component for the suppression of tumor cell growth. In this study, we investigated the time-course anticancer effects of adenoviral p53 (Adp53) infection on human ovarian cancer cells to provide insight into the molecular-level understanding of the growth suppression mechanisms involved in Adp53-mediated apoptosis and cell cycle arrest. MATERIALS AND METHODS: Three human cervical cancer cell lines (SiHa, CaSki, HeLa and HT3) were used. The effect of Adp53 infection was studied via cell count assay, cell cycle analysis, FACS, Western blot and macroarray assay. RESULTS: Adp53 exerts a significant role in suppressing cervical cancer cell growth. Adp53 also showed growth inhibitory effects in each cell line, and it induced apoptosis and cell cycle arrest. Adp53 differentially regulated the expression of genes and proteins, and the gene expression profiles in the SiHa cells revealed that the p21, p53 and mdm2 expressions were significantly up-regulated at 24 and 48 hr. Western blot shows that the p21 and p53 expressionlevels were significantly increased after Adp53 infection. In addition, in all cell lines, both the CDK4 and PCNA protein expression levels were decreased 48 h after Adp53 infection. Cell cycle arrest at the G1 phase was induced only in the SiHa and HeLa cells, suggesting that exogenous infection of Adp53 in cancer cells was significantly different from the other HPV-associated cervical cancer cells. CONCLUSION: Adp53 can inhibit cervical cancer cell growth through induction of apoptosis and cell cycle arrest, as well as through the regulation of the cell cycle-related proteins. The Adp53-mediated apoptosis can be employed as an advanced strategy for developing preferential tumor cell-specific delivery.

PURPOSE: Screening in cervical cancer is now progressing to discover candidate genes and proteins that may serve as biological markers and that play a role in tumor progression. We examined the protein expression patterns of the squamous cell carcinoma (SCC) tissues from Korean women with using two-dimensional polyacrylamide gel electrophoresis (2-DE) and matrix assisted laser desorption/ionization-time of flight (MALDI-TOF) mass spectrometer. MATERIALS AND METHODS: Normal cervix and SCC tissues were solubilized and 2-DE was performed using pH 3~10 linear IPG strips of 17 cm length. The protein expression was evaluated using PDQuest 2-D software(TM). The differentially expressed protein spots were identified with a MALDI-TOF mass spectrometer, and the peptide mass spectra identifications were performed using the Mascot program and by searching the Swiss-prot or NCBInr databases. RESULTS: A total of 35 proteins were detected in SCC. 17 proteins were up-regulated and 18 proteins weredown-regulated. Among the proteins that were identified, 12 proteins (pigment epithelium derived factor, annexin A2 and A5, keratin 19 and 20, heat shock protein 27, smooth muscle protein 22 alpha, alpha-enolase, squamous cell carcinoma antigen 1 and 2, glutathione S-transferase and apolipoprotein a1) were protein previously known to be involved in tumor, and 21 proteins were newly identified in this study. CONCLUSION: 2-DE offers the total protein expression profiles of SCC tissues; further characterization of these differentially expressed proteins will give a chance to identify the badly needed tumor-specific diagnostic markers for SCC.

BACKGROUND: The aim of this study was to investigate the prevalence, clinical and laboratory findings of hereditary hemolytic anemia (HHA) in Korea from 1997 to 2006 and to develop the appropriate diagnostic approach for HHA. METHODS: By the use of questionnaires, information on the clinical and laboratory findings ofHHA diagnosed from 1997 to 2006 in Korea was collected and analyzed retrospectively. A total of 431 cases were enrolled in this study from 46 departments of 35 hospitals. RESULTS: The overall frequency of HHA did not change through the 10-year period for pediatrics but did show an increasing tendency for internal medicine. The overall male to female sex ratio did not show sex predominance (1.17:1), but a significant male predominance with a ratio of 1.49:1 was seen for pediatrics while a significant female predominance with a ratio of 1:1.97 was seen forinternal medicine. Of the total cases, 74.2% (282/431) were diagnosed before the age of 15 years. The etiologies of HHA were classified as red cell membrane defects, hemoglobinopathies, red cell enzyme deficiencies and unknown causes. There were 382 cases (88.6%) of red cell membrane defects with 376 cases (87.2%) of hereditary spherocytosis and 6 cases (1.4%) of hereditary elliptocytosis, 20 cases (4.6%) of hemoglobinopathies with 18 cases (4.2%) of beta-thalassemia, a case (0.2%) of alpha-thalassemia and a case (0.2%) of Hemoglobin Madrid, 7 cases (1.6%) of red cell enzyme deficiencies with 5 cases (1.2%) of glucose-6- phosphate dehydrogenase (G-6-PD) deficiency, a case (0.2%) of pyruvate kinase (PK) deficiency and a case (0.2%) of enolase deficiency, and 22 cases (5.1%) of unknown causes. The most common chief complaint in pediatric patients was pallor and that in adult patients was jaundice. In the red cell membrane defect group of patients, the level of hemoglobin was significantly higher than in adult patients. The mean corpuscular volume, mean corpuscular hemoglobin, corrected reticulocyte count, total and indirect bilirubin level and lactate dehydrogenase levels in the hemoglobinopathy group of patients were significantly lower than the values in the red cell membrane defect group of patients. The mean concentration of G-6-PD was 0.8+/-0.7U/1012RBC in the G-6-PD deficient patients, PK was 1.7U/1010 RBC in the PK deficient patient, and the level of enolase was 0.04U/g of Hb in the enolase deficient patient. CONCLUSION: The most prevalent cause of HHA in Korea during 1997 to 2006 was hereditary spherocytosis, but HHA by other causes such as hemoglobinopathy and red cell enzyme deficiency gradually increased with the development of molecular diagnostic methods and increasing general interest. However, the etiologies of HHA need to be pursued further in 5.1% of the patients. An systematic standard diagnostic approach is needed in a nationwide prospective study for correct diagnoses and appropriate management of HHA.
