Purpose: This study aimed to identify the effect of fetal attachment and pregnancy on health promoting behavior in primigravida. Methods: The subjects were 149 primigravidas who enrolled in nationwide online cafe for pregnant and childcare women. The data were collected from February, 2008 to February, 28 in 2022. The collected data were analyzed by IBM SPSS Statistics ver. 24.0. Results: The primigravidas’ health promoting behavior was significantly affected by the fetal attachment (β=0.37, p<0.001), spouse stress (β=0.32, p<0.001), subjective health condition (β=0.28, p<0.001), academic background (β=0.25, p<0.001), primigravidas themselves stress (β=-0.24, p=0.001), and monthly income (β=0.18, p=0.005). These variables explained 41.5% of the variance in health promoting behavior. Conclusion It is necessary to seek out how to improve the fetal attachment through interactions with fetus, for enhancing primigravidas’ health promoting behavior and to develop a program by educational levels, for forming positive mind about health. Moreover, various efforts and strategies are required to reduce the pregnancy stress and enhance the health of both primigravidas and fetus, by early detecting and alleviating the pregnancy stress.

Nine typical cases of ossifying fibroma in the tibia or fibula were retrospectively reviewed for clinical and histopathological aspects of this disease. Along with the case analysis, light and polarized microscopic examinations were performed in each case. Differential points with monostotic fibrous dysplasia were as follows; 1) ossifying fibroma begins in the significantly younger age, which is in most cases below 10 years of age, 2) it is confined to diaphysis of tibia or fibula, 3) radiologically, multilocular osteolytic destructive change in eccentric pattern is usually combined with anterior or anterolateral bowing deformity, 4) microscopically, characteristic findings are presence of osteoblastic rimming, peripheral maturation, and zonal phenomenon. In the treatment of ossifying fibroma, definitive surgical treatment should be delayed until skeletal maturity, when segmental resection in wide margin including periosteum might be preferred.

BACKGROUND: It is clear that deregulation of coil cycle progression is a hallmark of neoplastic transformation and genes involved in the G1/S transition of the coil cycle are especially frequent targets for mutations in human cancers, including lung cancer. P16 gene product, one of the G1 cell-cycle related proteins, that is recently identified plays an important role in the negative regulation of the kinase activity of the cyclin dependent kinase (cdk) enzymes. Therefore p16 gene is known, to be an important tumor suppressor gene and is also called MTS1 (multiple tumor suppressor 1). No more oncogenes have ken reported to be frequently related to multiple different malignancies than the alterations of p16 gene. Especially when it comes to non-small cell lung cancer, there was no expression of p16 in more than 70% of cell lines examined. Ann also it is speculated that p16 gene could exert a key role in the development of non-small cell lung cancer. This study was designed to evaluate whether p16 gene ould be used as a candidate for gene therapy of non-small cell lung cancer. METHODS: After the extraction of total RNA from normal fibroblast cell line and subsequent reverse transcriptase reaction and polymerase chain reaction, the amplified P16 cDNA was sukloned into eukaryotic expression plasmid vector, pRC-CMV. The constructed pRC-CMV-p16 was transfected into the NCI-H441 NSCLC cell line using lipofectin. The changes of U I cell-cycle related proteins were investigated with Western blot analysis and immunoprecipitation after extraction of proteins from cell lysates and tumor suppressive effect was observed by clonogenic assay. RESULTS: (1) p16(-) NCI-H441 cell line transfected with pRC-CMV-p16 showed The formation of p16 : cdk 4 complex and decreased phosphorylated Rb protein, while control cell line did not. (2) Clonogenic assay demonstrated that the number of colony formation was markedly decreased in p16(-) NCI-H441 cell line transfected with pRC-CMV-p16 than the control cell line. CONCLUSION: It is confirmed that the expression of p16 protein in p16 absent NSCLC cell line with the gene transfection leads to p16 cdk4 complex formation, subsequent decrease of phosphorylated pRb protein and ultimately tumor suppressive effects. And also it provides the foundation for the application of P16 gone as a important candidate for the gene therapy of NSCLC.

BACKGROUND: Recently, the molecular pathologic investigation for clonality in lymphomas has been introduced and has gained a role in the diagnosis of lymphomas. In fact, the clonality test using TCRGR phenomenon has been done by Southern blot analysis (SBA) and polymerase chain reaction (PCR) for molecular pathologic diagnosis of T cell lymphomas. However, it is difficult to perform SBA with paraffin embedded specimens or with samples of small skin biopsies. OBJECTIVE: We investigated the efficacy of PCR amplification of TCR gene in paraffin em-bedded cutaneous T cell lymphomas. METHODS: Iii this study, the clonality was assessed by polymerase chain reaction (PCR) analysis of T cell receptor gamma (TCR) gene from the DNA extracts obtained from paraffin em-bedded tissues (PET) of malignant T cells, B cell lymphomas, and benign cutaneous T cell proliferative disorders. Heteroduple-x-analyses were also performed to rule out the false positives. RESULTS: Among the total of 62 cases analyzed, monoclonality was observed in 4 out of 10 mycosis fungoides, 7 out of 9 cutaneous T cell lymphomas excluding mycosis fungoides, 1 out of 3 angiocentric lymphomas, 2 out of 2 lymphomatosis papulosis, 1 out of 7 large plaque parapsoriasis, and 1 out of 2 T cell lymphomas in other organs. No monoclonality was observed in 9 inflammatory cutaneous diseases, 5 small plaque parapsoriasis, 4 cutaneous B cell lymphomas, and 11 B cell lymphomas in lymph nodes. CONCLUSION: The results suggest that the PCR method and heteroduplex analysis used in this study were not only practical but also efficacious for the diagnosis of cutaneous T cell lymphomas using tissues embedded in paraffins.

PURPOSE: F-18-fluorodeoxyglucose (FDG) positron emission tomography (PET) has been proven to be useful in the differential diagnosis of breast mass and staging of breast cancer. This study assessed the diagnostic accuracy of F-18-FDG PET in the differentiation of breast mass and staging of breast cancer. MATERIALS AND METHODS: Total 42 patients who had breast mass underwent F-18-FDG PET (all female, 40+/-10 year old). We compared F-18 FDG PET results with pathologic findings in 24 patients RESULTS: In the differentiation of breast mass, sensitivity and specificity were 95% (19/20) and 77% (7/9) respectively. Three false positive cases were due to inflammation and one false negative patient had small tumor less than 1 cm. In the assessment of axillary lymph node status, sensitivity and specificity were 73% (8/11) and 100% (7/7) respectively. We found distant metastasis that were not suspected before F-18-FDG PET in 2 patients. CONCLUSION: F-18-FDG PET shows good diagnostic performance in differentiation of breast mass and staging of breast cancer.

STATEMENT OF PROBLEM: One of the common problems of dental implant prosthesis is the loosening of the screw that connects each component, and this problem is more common in single implant-supported prostheses with external connection, and in molars. PURPOSE: The purposes of this study were: (1) to compare the initial abutment screw detorque values of the six different implant-abutment interface designs, (2) to compare the detorque values of the six different implant-abutment interface designs after cyclic loading, (3) to compare the detorque values of regular and wide diameter implants and (4) to compare the initial detorque values with the detorque values after cyclic loading. MATERIAL AND METHODS: Six different implant-abutment connection systems were used. The cement retained abutment and titanium screw of each system were assembled and tightened to 32Ncmwith digital torque gauge. After 10 minutes, initial detorque values were measured. The custom titanium crown were cemented temporarily and a cyclic sine curve load(20 to 320N, 14Hz) was applied. The detorque values were measured after cyclic loading of one million times by loading machine. One-way ANOVA test, scheffe's test and Mann-Whitney U test were used. RESULTS: The results were as follows : 1. The initial detorque values of six different implant-abutment connections were not significantly different(p> 0.05). 2. The detorque values after one million dynamic cyclic loading were significantly different (p <0.05). 3. The SS-II regular and wide implant both recorded the higher detorque values than other groups after cyclic loading(p <0.05). 4. Of the wide implants, the initial detorque values of Avana Self Tapping Implant, MIS and Tapered Screw Vent, and the detorque values of MIS implant after cyclic loading were higher than their regular counterparts(p <0.05). 5. After cyclic loading, SS-II regular and wide implants showed higher detorque values than before(p <0.05).

Cowden syndrome (CS), also known as multiple hamartomas syndrome, is a rare hereditary autosomal dominant disorder caused by a germline mutation in the phosphatase and tensin homolog (PTEN) gene mapped on chromosome 10. The clinical features of CS are variable, primarily presenting as mucocutaneous lesions (99%). A mucocutaneous lesion, such as trichilemmoma of the face or keratosis of the extremities, is an important diagnostic marker for CS. CS has been reported to increase the incidence of benign and malignant neoplasms in the breast, thyroid, and gastrointestinal tract. The risk of developing malignancy in individuals with CS is up to 10 times higher than general population throughout an entire life time.

PURPOSE: Either gated myocardial perfusion SPECT or attenuation corrected SPECT can be used to improve specificity in the diagnosis of coronary artery disease. We investigated in this study whether gating or attenuation correction improved diagnostic performance of rest/stress perfusion SPECT in patients having intermediate pre-test likelihood of coronary artery disease. MATERIALS AND METHODS: Sixty-eight patients underwent rest attenuation-corrected T1-20l/dipyridamole stress gated attenuation-corrected Tc-99m-MIBI SPECT using an ADAC vertex camera (M:F=29:39, aged 59+/-12 years, coronary artery stenosis> or =70%. one vessel: 13, two vessel: 18, three vessel: 8, normal: 29). Using a five-point scale, three physicians graded the post-test likelihood of coronary artery disease for each arterial territory (1 normal, 2: possibly normal 3:equivocal, 4: possibly abnormal, 5: abnormal). Sensitivity, specificity and area under receiver-operating-characteristic curves were compared for each operator between three METHODS: (A) non-attenuation-corrected SPECT; (B) gated SPECT added to (A); and (C) attenuation-corrected SPECT added to (B). RESULTS: When grade 3 was used as the criteria for coronary artery disease, no differences in sensitivity and specificity were found between the three methods for each operator Areas under receiver- operating-characteristic curves for diagnosis of coronary artery disease revealed no differences between each modality (p>005). CONCLUSION: In patients at intermediate risk of coronary artery disease, gated SPECT and attenuation-corrected SPECT did not improve diagnostic performance.
