Allelic deletions involving the short arm of chromosome 3(3p13-21.1) have been observed frequently in cervical carcinomas. Recently the fragile histidine triad(FHIT) gene was cloned and mapped to this chromosomal region(3p14.2). From various studies involving tumor cell lines and primary cancers, the FHIT gene has been presumed to be a candidate for tumor suppressor gene involving various tumors. In FHIT gene, the most common aphidicolin-inducible fragile site, FRA3B exists and the FRA3B has been considered as a region of the spontaneous integration site of HPV 16. In order to elucidate the role of the FHIT in carcinogenesis of cervical cancer, this study was designed to investigate both the expression of FHIT protein in normal, preinvasive and invasive cancer samples employing immunohistochemical study and allelic loss of FHIT gene locus against several microsatellite markers employing the PCR analysis. Immunohistochemical studies of FHIT protein revealed following features. In normal ectocervical squamous epithelium, the expression of FHIT was relatively weak and confined to the basal layer, but in normal endocervical glandular epithelium it was very strong. The expression of FHIT was reduced as the tumor progressed from early lesion to invasive cancer. The koilocytosis was associated with diminished expression of FHIT protein. The study of allelic loss of FHIT gene locus was undertaken against two intragenic (D3S1300, D3S1234) and one extragenic (D3S1295) microsatellite markers. The 5th intron, D3S1300, showed allelic change in 6 of 15 assays and 7th intron, D3S1234 showed allelic change in 10 of 29 assays. There was no apparent LOH from 29 assays in D3S1295. In conclusion, the expression of FHIT protein was markedly reduced or absent in cervical squamous cell carcinoma and the chromosome breakage in FHIT region might be related to the diminished expression of FHIT. On the basis of the reduced expression of FHIT and its encompassment of FRA3B region, it is suggested that disruption of FHIT, a putative tumor suppressor gene, might be the mechanism by which HPV infection enhances cervical tumorigenesis and clonal outgrowth.

The purpose of this study was to evaluate the effects of thermocycling on the shear bond strength of Co-Cr alloy to denture base resin. PMMA denture base resin such as heat-cured Vertex-RS , self-cured Vertex-SC and 4-META denture base resin such as heat-cured Meta-Dent , self-cured Meta-Fast was bonded to Co-Cr alloy. Samples were divided into 3 groups : no thermocycling group as control, thermocycling between 5degrees C and 55degrees C with 15 second dwell time as group 1, thermocycling with 1 minute dwell time as group2. The shear bond strength was measured and the interface between metal and resin was observed by SEM. The results were as follows. 1. The shear bond strength decreased significantly according to thermocycling and dwell time(P<0.001). 2. The bond strength of Co-Cr alloy and 4-META denture base resin was significantly higher than that of Co-Cr alloy and PMMA denture base resin(P<0.001). 3. IN SEM, there was no gap in control group, but there was much and large gap in group 1, 2. The longer dwell times, the lower bond strength. PMMA denture base resin had more gap than 4-META denture dwell times, the lower bond strength. PMMA denture base resin had more gap than 4-META denture base resin in the interface. These results revealed that thermocycling decreased the bond strength between Co-Cr alloy and denture base resin and dwell time of thermocycling changed the effect of thermocycling. The results suggested that oral temperature change affect the bond strength of prosthesis.

This study examined burdens of primary family carcgivcrs of paticnto with cerebrovascular accidents (CVA) along with related factors. In addition, their needs for support group intervention were assessed to develop a support group to reduce the burdens of caregiving. Eighty-one primary family caregivers of patients with CVAs at a general hospital in Seoul participated in this study . The patients with CVAs aged from 26 to 83 years with mean age of 63 years. About 90% of the patients had some paralysis and 56.6% suffered speech problems. Fifty-eight percent of the primary family caregivers were spouses of the patients and 80.2% were women. Primary family caregivers' burdens were assessed by the Burden Scale originally devel oped by Zarit (1980) and Novak & Geust(1989) and modified by Jang (1995) for use in Korea. The instrument consists of six subscales time-dependent burden, developmental burden, physical burden, emotional burden, social burden, and financiaI burden. The results were as follows : 1. The average of burden score was 91.7, indicating moderate to severe level of burden. The time-dependent burden was scored highest followed by physical, developmental, social, financial, and emotional burdens. 2. of the characteristics of patients, age, gender, and severity of the disease were found to be associated with the level of burden. Of the characteristics of primary family caregivers, age and educational level were significantly related to the level of burden. Time of care since the CVA and the quality of relationship between a patient and a caregiver prior to the stroke were significant situational factors affecting the level of burden. 3. The need for support group intervention for the caregivero was very high (95.1%). The earcgivcrs of patients who had a CVA for the first time showed higher levels of need compared to those of patients who had a CVA more than once. The caregivers indicated a support group held once a month near home or hospital would be welcomed. In addition, they replied that a group composed of 9 to 10 caregivers and guided by health care professionals (e.g., physicians and nurses) would be most desirable. More than 85% of the earegivers identified the areas that they wanted intervention in as follows : knowledge, skills, and resources to care for a patient with a CVA. the counsel of health care professionals, share of their experiences with those who have similar situations, stress management skills, and methods to overcome emotional isolation due to the great responsibility for a patient. Given the results, support group is expected to be an effective way to reduce the burdens of primary family caregivers of patients with CVAs. As a follow up It is necessary to examine the effect of support group intervention on the patient's recovery and rehabilitation.

Hyperinsulinemic hypoglycemia is a relatively rare disease in childhood period except neonate, but hypoglycemia due to delicate imbalance between glucose production & consumption is evoked easily and left permanent damage to brain at these period. The definition is that serum insulin level is above 10microU/ml when blood sugar level is below the 40mg/dl and so I/G ratio is higher than 0.4. The clinical manifestations are irrtability, frequent feeding and seizures etc. and there is no specific pancreatic pathology in most cases. We experienced 2 cases of hyperinsulinemic hypoglycemia with pancreatic hyperplasia and pancreatic adenoma each other. The diagnosis was made on clinical manifestations, laboratory results, radiologic and pathologic findings. We reported these cases with brief review of literature.

Amniotic band syndrome is an uncommon congenital fetal abnormality with defects of skin resulting in ringlike strictures about the limbs and occasionally the trunk. Its pathogenesis has been still debated in the literature for many years. Amniotic band syndrome features multiple disfiguring and disabling manifestations. A clinical deformities include limb defects, craniofacial defect, visceral defect, body wall defect and other anomalies. We had experienced a case of amniotic band syndrome with retinopathy of prematurity, bilateral orofacial cleft, aphalangia of right hand, ventricular septal defect and atrial septal defect. We report this case with a brief review of the literature.

Purpose: This study investigated the complications and patterns of implants that confronted with the extruded natural teeth. Materials and Methods: Among patients who received implant treatment between 2006 and 2018 at Chosun University Dental Hos-pital, only implants that had a maintenance period of at least 5 years and that both implants and confronting natural teeth could bemeasured and compared on a radiograph were selected. They were divided into two groups. Group 1, experimental group consisted of Implants confronting the extruded natural posterior teeth (n = 167: maxilla (Group 1max ) = 92, mandible (Group 1man ) = 75) and Group 2, control group consisted of Implants confronting the normal natural posterior teeth (n = 656: maxilla (Group 2max ) = 272, mandible (Group 2man ) = 384). Results: The incidence of complications between Group 1 and Group 2 was statistically significant. In particular, there was a statistically significant difference between the frequency of marginal bone loss and the amount of marginalbone loss. Conclusion The extruded natural tooth may cause more frequent complications including bone resorption in the oppos-ing implant.
