STATEMENT OF PROBLEM: Resin cements are widely used in adhesive dentistry specially on all ceramic restorations. It is needed to find out adequate bonding strength between different porcelain surface treatments, commercially available porcelains, and different resin cement systems. PURPOSE: The purpose of this study was to evaluate shear bond strength of resin cements bonded to porcelains in three different modalities; 5 different porcelain surface treatments, 3 different resin cement systems and 3 different commercially available pressable porcelains. MATERIAL AND METHOD: This study consisted of 3 parts. Part I examined the effect of five different surface treatments on the pressable porcelain. Fifty discs (5 mm in diameter and 3 mm in height) of Authentic porcelain were randomly divided into 5 groups (n = 10). The specimens were sanded with 320 grit SiC paper followed by 600 grit SiC paper. The specimens were treated as follow: Group 1-Sandblasting (aluminum oxide) only, Group 2 - sandblasting/silane, Group - sandblasting/acid etching/silane, Group 4 - acid etching only, Group 5 - acid etching/silane. Part II examined the shear bond strength of 3 different resin cement systems (Duolink, Variolink II, Rely X ARC) on acid etching/ silane treated Authentic pressable porcelain. Part 3 examined the shear bond strength of Duolink resin cement on 3 different pressable porcelains (Authentic, Empress I, Finesse). All cemented specimens were stored in distilled water for 2 hours and tested with Ultradent shear bond strength test jig under Universal Instron machine until fracture. An analysis of variance(ANOVA) test was used to evaluate differences in shear bond strength. RESULT: The shear bond strength test resulted in the following: (1) Acid etched porcelains recorded greater shear bond strength values to the sandblasted porcelains. (2) Silane treated porcelains recorded greater shear bond strength values to non-silane treated porcelains. (3) There was no significant difference between sandblasting/acid etching/silane teated and acid etching/silane treated porcelains. However those values were much higher than other three groups. (4) The shear bond strength with Variolink II was lower than the value of Duolink or Rely X ARC. (5) The shear bond strength of Finesse was lower than the value of Authentic or Empress I.

Over a period of recent two years, 100 patients who had localized pulmonary lesions and underwent percutaneousneedle aspiration and biopsy, were analized. There were 56 malignancies and 44 benign and 79% respectively.Differentiation of malignancy vs. benignity was possible in 89% of cases obviating unnecessary exploratorythoracotomy for diagnostic purpose, Five cases were misinterpreted and eight cases were non-diagnostic oncytology. Inadequate materail was obtained in two cases; one was due to hardness of the mass, which, later,confirmed as chondrosarcoma, and the other was too samll(0.8x1.0cm) to be visible on lateral view. Theobainenability of the tissue was 98%. 14(14%) patients developed pneumothorax; one of them required treatment andthe reminder showed spontaneous resporption. (Transient neglibigle blood tinged sputum was found in 16(16%)cases.) The method, problems and complications are discussed. Authors recommend the percutaneous needle aspirationand biopsy as the initial procedure in diagnostic work-up of pulmonary coin lesions, especially when they aresmaller, more peripheral and metastatic neoplasm is neoplasm is suspected.

As evidence-based practice has become an important issue in healthcare settings, the educational needs for knowledge and skills for the generation and utilization of healthcare evidence are increasing. Systematic review (SR), a way of evidence generation, is a synthesis of primary scientific evidence, which summarizes the best evidence on a specific clinical question using a transparent, a priori protocol driven approach. SR methodology requires a critical appraisal of primary studies, data extraction in a reliable and repeatable way, and examination for validity of the results. SRs are considered hierarchically as the highest form of evidence as they are a systematic search, identification, and summarization of the available evidence to answer a focused clinical question with particular attention to the methodological quality of studies or the credibility of opinion and text. The purpose of this paper is to introduce an overview of the fundamental knowledge, principals and processes in SR. The focus of this paper is on SR especially for the synthesis of quantitative data from primary research studies that examines the effectiveness of healthcare interventions. To activate evidence-based nursing care in various healthcare settings, the best and available scientific evidence are essential components. This paper will include some examples to promote understandings.

PURPOSE: The purpose of this study is to examine the relationship among body image, depression and sexual function in Korean postmenopausal women. METHODS: Subjects were 96 postmenopausal women who have lived in Korea. Data was collected using Semantic Differential scale, CES-D, and FSFI. RESULTS: The level of body image was positive, depression was mild, and sexual function was moderate. There were no significant correlation between depression and sexual function. The subjects who had more positive body image experienced higher sexual function and less depressed mood. CONCLUSION: These findings showed the need for a knowledge development program for nurses regarding women's sexual function. Also, nurses must do counseling with sexual partner's and consider patients' body image when counseling those who complain of sexual dysfunction

To delineate the coronary anatomy and left ventricular function during early myocardial infarction, coronary arteriography and left ventriculogrphy were performed, prospectively in 23(22%) of 105 patients who were admitted to the coronary care unit at Masan Koryo Hospital from June 1986 to June 1988 within 4 weeks after the onset of symptoms(medium:21 days, range:18 days to 25 days). 1) Among 23 patients, male is 20 patients and female is 3 patients. The ratio of male to female was 6.6:1. The mean age was 55.4+/-10.3 years(range:34-77 years). 2) Coronary artery narrowing state which related to myocardial infarction was as follows; 2 patients(7%) had normal, 1 patients(4%) had insignificant narrowing(below 50%) 5 patients(22%) had moderate narrowing(50-75%), 10 patients(43%) had severe narrowing(75-99%), 5 patients(22%) had complete occlusion(100%). 3) The range of coronary artery disease was as follows; 9 patients had one vessel disease, 10 patients had two vessel disease, 1 patients had three vessel disease, and ejection fraction had no significant difference among 3 groups but lowest in three vessel disease. Among 23 patients, 13 patients had anterior infarction, 10 patients had inferior infarction. 4) Left ventricular ejection fraction and multiple vessel disease had no significant difference between i) the young(under 45 years old) and the old(over 45 years old) age groups, ii) presence or non presence of previous angina, iii) Killip classification I, II and III, IV) anterior infarction and inferior infarction. 5) In left ventriculography, akinesis and dyskinesis were shown at similar ratio in anterior infarction and inferior infaraction. Dyskinesis was shown in 27% of patients who have 0-1 vessel disease, 50% of patients who have 2-3 vessel disease, 62% of patients who have collateral circulation, 26% of patients who dose not have collateral circulation. 6) Collateral circulation was found in 8 patients(35%). Age and left ventricular ejection fraction were high in patients without collateral circulation than with collateral circulation, but there is no significant difference and collateral circulation exists regardless of infarction site and range of coronary artery disease. 7) As for the complication of angiocardiography in this study, there was ventricular tachycardia in 3 patients(13%) without mortality. It is concluded that coronary arteriography can be safely performed in early stage after acute myocardial infarction. Also good prognosis is anticipated since three vessel disease and complete occlusion were low in acute myocardiaol infarction of Korean People. Since these are not much case performed study, however more study on this area is required.

This experiment was performed to study the morphological responses of the thymic cortex of the mice after administration of BCG. Healthy adult mice weighing 25gm each were divided into normal and experimental groups. BCG[0.03X108-0.32X108 CFU] were injected subcutaneously to the animals every other day, and animals were sacrificed at 4 days, 1 week, 2 weeks and 8 weeks following the first injection. Thymus were removed immediately after sacrifice and transferred to cold phosphate buffered 2.5% glutaraldehyde-1.5% paraformaldehyde solution[pH 7.3], and cut into small pieces. Tissue samples were fixed for 2-3 hours in the same fixative, postfixed with phosphate buffered 1% osmium tetroxide solution[pH 7.3], dehydrated in a graded series of alcohol, and embedded in araldite mixture. Ultrathin sections stained with uranyl acetate and lead citrate were observed with a JEM 100CX-II electron microscope. The observed results were as follow : 1. In the early BCG treated groups, a few eosinophile leucocytes were observed, but more eosinophils were observed in later groups. Some elongated and bar-shaped lysosomes with eletron lucent gap were often obserced in the macrophages. 2. Cortical population of thymocytes in the thymus were reduced, whereas territoris of the epithelial reticular cells were expanded especially in 2 weeks and 8 weeks groups. Some portion of the thymic cortex exhibited large intercellular spaces, and a few nuclear bodies filled with materials of medium density were observed in the epithelial reticular cells. 3. In the 8 weeks groups, macrophages, plasma cells and eosinopile leucocytes and developing eosinophile leucocytes were often observed in the thymic cortex. Distended cisternae of granular endoplasmic reticula and newly forming prosecretory granulses in the Golgi complex were ovserved in som plasma cells. From the above results, it was suggested that repeated treatment with BCG could induce disturb the maturation and differentiation of the T lymphocytes. In turn, BCG, if repeatedly injected, may disturb the immunological medchanism.

The infrapatellar fat pad (IPFP) is one of three fat pads located about the anterior knee. Injury in this region is relatively common. Damage to the IPFP is caused mostly by an iatrogenic injury from a surgical procedure or repeated small collision trauma. The authors experienced a case of an IPFP injury, that has not been reported in the domestic or international literature. In this case, acute IPFP separation followed by a contusion at the anterior aspect of knee in the kneeling position, confirmed using magnetic resonance imaging. The patient was fully recovered with conservative treatment.

Esophageal hematoma is a rare form of esophageal injury. It may occur spontaneously, or in association with direct esophageal damage or a bleeding diathesis. Endoscopy and computed tomography are generally necessary for the establishment of a diagnosis. In this report, we present a case of esophageal hematoma that was discovered via a bedside transthoracic echocardiography. The echocardiography was conducted to evaluate an unexplained shock in a critically ill-patient. After conservative treatment, complete resolution of the esophageal hematoma was documented by a 7-day short-term follow-up of bedside transthoracic echocardiography. To the best of our knowledge, this is the first case report regarding transthoracic echocardiographic detection, differential diagnosis, and follow-up for esophageal hematoma.

A double pylorus, a fistulous communication between the gastric antrum and duodenal bulb, is a very rare anomaly. It appears as an acquired lesion in the majority of cases and mainly occurs in males with chronic obstructive pulmonary disease, chronic renal failure, chronic rheumatism, systemic lupus erythematosus, or diabetes. However, there are no previous reports of a double pylorus combined with diabetes mellitus in Korea. Recently we experienced a case of double pylorus caused by a peptic ulcer in 74-year-old man who had diabetes mellitus with complications. We report this case with a review of the literature.
