This study investigated the effect of thickness of flowable resin lining on marginal leakage in class II composite restorations. 80 experimental teeth were prepared with class II preparations with enamel margin or dentin margin. Each group was devided into four groups according to flowable resin lining thickness ; Control group - no flowable resin lining, Group 1 - 0.5 mm flowable resin lining, Group 2 - 1 mm flowable resin lining, Group 3 - 2 mm flowable resin lining. The cavities were restored using Scotchbond Multi-Purpose adhesive system, Filtek Flow and Filtek Z 250 composite resin. Following one day storage in distilled water, the restored teeth were thermocycled for 500 cycles and immersed in 2% methylene blue for 24 hours. The results of this study were as follows: 1. Ranking of mean microleakage scores at the enamel margins was Group 1 < Control = Group 2 < Group 3. The microleakage of Group 3 was significantly higher than that of Control, Group 1 and Group 2 (p < 0.05). 2. Ranking of mean microleakage scores at the dentin margins was Group 1 < Group 2 < Control < Group 3. The microleakage of Group 3 was significantly higher than that of Control, Group 1 (p < 0.05). 3. Compared with microleakage between the enamel and dentin margins, enamel margin group were significantly lower than dentin margin group.

The authors analysed the interpupillary distance and the distance between optical centers in 200 spectacles wearers. The results were as follows; 1. Among the 200 glasses wearers, the cases of hospital prescriptions were 44 persons and the cases of optical shops prescriptions were 156 persons. 2. Hyperopic glasses wearers were 26 persons and myopic glasses wearers were 174 persons. 3. The distance between optical centers was coincided to the interpupillary distance in 26 persons and discrepant in 174 persons. 4. In 115 eyes the prismatic effects were more than 0.5 prism diopter, and maximal prismatic effect was 5.78 prism diopters. 5. The evaluation of the induced horizontal phoria showed that 119 persons had the induced esophoria and 55 persons had the induced exophoria. In 58 persons induced phoria were more than 1 prism diopter. Maximal induced esophoria was 11.55 prism diopters and maximal induced exophoria was 4.30 prism diopters.

Ankylosing spondylitis is a chronic, progressive, inflammatory arthritis that affects principally the sacroiliac joints and spine. Approximately 25% of cases are associated with an acute recurrent nongranulomatous iridocyclitis. This disease occurs most frequently in the second and third decades of the life. Males are affected more frequently than females. There is a striking association between this disease and presence of histocompatibility antigen HLA-B27, which is found in only 4% to 9% of controls. The antigen is present in 88% to 96% of those with ankylosing spondylitis and in 55% of those with uveitis. The authors experienced lease of acute recurrent uveitis associated with ankylosing spondylitis in a 47 year old male patient. We performed radiologic and laboratory examinations. Radiologic examinations revealed the massive and diffuse calcification of all paravertebral ligaments showing a "bamboo spine" appearance. Laboratory examinations revealed elevated ESR and positive HLA-B27. We treated him with the systemic and topical steroids and topical mydriatics, and had a good result.

PURPOSE: The transaxillary approach for breast augmentation has been advocated for patients and surgeons for several decades. However, this blind technique had many disadvantages including, traumatic dissection, difficult hemostasis, displacement of implants, and ill-defined asymmetrical location of inframammary crease. In the present study, the precise endoscopic electrocautery dissection was applied to eliminate the limits of blunt dissection throughout the procedures. METHODS: From December 2006 to December 2007, a total of 103 patients with an average age of 29.5 years underwent endoscopic assisted transaxillary dual plane augmentation mammoplasty. The mean implant size was 243 cc with the range between 150 and 350cc. Through a 4cm axillary incision, electrocautery dissection for submuscular pockets was carried out under the endoscopic control. The costal origin of pectoralis muscle was completely divided to expose subcutaneous tissue and to make type I dual plane. RESULTS: Using the endoscopic dissection, we achieved good aesthetic results including a short recovery period, less morbidity, and symmetrical well-defined inframammary crease. Type I dual plane procedure could support the consistent inframammary fold shape and be applied to most patients without breast ptosis. Minor complications did not occur, however, four major complications of capsular contracture occurred. CONCLUSION: In contrast to the era of the blind techniques, endoscopic assisted transaxillary dual plane breast augmentation can now be performed effectively and reproducibly. With Its advantage, the axillary application of endoscopy for augmentation mammaplasty is useful to achieve the optimal cosmetic outcomes.

The cell cycle is composed of a series of steps which can be negatively or positively regulated by various factors. p53 gene aberrations are common in human malignancies, and recent studies suggest that in cervical carcinoma p53 function is inactivated either by complex formation wilh human papilloma virus (HPV) E6 product or by gene mutation. To study the expression of p53 gene in the cervical cancer and cervical intraepithebal neoplasia, immunohistochemistry for the p53 protein was done in the 47 cases of squamous cell carcinoma, 6 cases of adenocarcinoma and 32 cases of cervical intraepithelial neoplasia. I. The p53 protein was detected in the 31% of cervical intraepithelial neoplasia (10/32 cases). 2. The p53 protein was detected in the 55% of invasive cervical cancer (29/53 cases). 3. By the histologic type of cervieal cancer, the p53 protein was detected in the 57% of squamous cell carcinoma (27/47 cases) and 33% of(2/6 cases) adenocarcinoma. The p53 protein wes more frequently detected in the squamous cell carcinoma than in the adenocarcinoma. 4. By the staging in cervical cancer, the p53 protein was detected in the 31% of stage 0, 50% of Stage Ia, 50% of stage I b, 75% of IIa and 50% of stage II b.

This study was undertaker to define the usefuness of preoperative CA-125 assay as a diagnostic bmor marker in differentiating malignancy from benign ovarian mass. Senun CA-125 were imneasured by Microparticle Enzyme Immunoassay(MEIA) in 94 patients with ovarian mass. The results were of follows ; 1. The mean value of preopentive senun CA-125 was 18.40u/ml in benign ovarian mass and 225.99u/ml in malignant ovarian mass (P<0.001). 2. The positive rete of Ca-125 in benign ovarian mass was 10%, compared 80% in malignant ovarian mass. 3. In analysis of histolovgic type, posisitive rate of serum CA-125 in malignant serous tumor was 82%, cornpared 50% in malignant mucinoins tumor. 2. No statistically significant correlation was observed between CA-125 value and patient's age. 5. The sensitivitiy, specifieity, positive predictive value & negative predictive value were 80%, 90%, 60% & 96%, respectively in cut off value, 35u/ml, And increasing cut off value 65u/ml, sensitivity, specificity, positive predictive value & negative predictive value were 40%, 96%, 67%, 90%, resqxetively. These data suggest the preperative serum CA-125 level correlate with maignant stattis in ovarian mass. And cut off value 35u/ml was better than 65u/ml in screening for ovarian cancer.
