PURPOSE. The purpose of this study was to provide an actual guideline in determining the shape, diameter, and position of the implant in immediate implantation by the measurement of the thickness of facial and palatal plate, the thickness of cortical bone on the facial and palatal plate, the diameter of the root, and the distance between the roots in the cadavers. MATERIALS AND METHODS. The horizontal sections of 20 maxillae were measured and analyzed to obtain the average values. Resin blocks were produced and cut serially at 1 mm intervals from the cervical line to the root apex. Images of each section were obtained and the following measurements were performed: The thickness of the facial and palatal residual bone at each root surface, the thickness of the facial and palatal cortical bone at the interdental region, the diameter of all roots of each section on the faciopalatal and mesiodistal diameter, and the interroot distance. Three specimens with measurements close to the average values were chosen and 3-dimensional images were reconstructed. RESULTS. The thickness of the facial and palatal cortical bone at the interdental region in the maxilla, the buccal cortical bone was thicker in the posterior region compared to the anterior region. The interroot distance of the alveolar bone thickness between the roots increased from anterior to posterior region and from coronal to apical in the maxilla. CONCLUSION. In this study, the limited results of the morphometric analysis of the alveolar ridge using the sections of maxilla in the cadavers may offer the useful information when planning and selecting optimal implant for immediate implantation in the maxilla.

ABSTRACT: Hundreds of proteins involved in signaling pathways contain a Ca^(2+)-dependent membrane-binding motif called the C2-domain. However, no small C2-domain proteins consisting of a single C2-domain have been reported in animal cells. We have isolated two cDNA clones, OsERG1a and OsERGIb, that encode two small C2-domain proteins of 156 and 159 amino acids, respectively, from a fungal elicitor-treated rice cDNA library. The clones are believed to have originated from a single gene by alternative splicing. Transcript levels of the OsERG1 gene are dramatically elvated by a fungal elicitor prepared from Magnaporthe grisea or by Ca^(2+) ions. The OsERG1 protein produced in Escherichia coli binds to phospholipid vesicles in a Ca^(2+)-dependent manner and is translocated to the plasma membrane of plant cells by treatment with either a fungal elicitor of a Ca^(2+)-ionophore. These results suggest that OsERG1 proteins containing a single C2-domain are involved in plant defense signaling systems.

Rectal carcinoid tumor is relatively rare neoplasm orignated in Kulchitszky cell and clinicians have the difficulties in predicting their malignant potential and in proper treatrnent. The vast majority of rectal carcinoid tumors are benign and can be safely treated by local excision. Lesions larger than 2 cm and invading the muscular wall of the rectum should be considered rnalignant and treated by more radical surgery such as abdominoperineal resection. 3Ve had a case of 35-year-old male patient with a malignant rectal carcinoid tumor 2 cm in the length diagnosed by colonofiberscopy. So we present this case with a review of relevant literatures.

Rare cause of Cushing's syndrome, known as macronodular adrenocortical hyperplasia may be found sometimes with biochemical and radiological features mimicking adrenal adenoma. Cushing's syndrome due to nodular adrenal hyperplasia comprises a clinical and biochemically heterogeneous group of disorders whose pathogenesis is unclear. But, it has been suggested the concept of dual control with semiautonomy of the adrenal nodules and predominence of the pituitary at one time and of the adrenal at another. We describe a patient with atypical steroid dynamics and with a 1.8cm diameter unilateral adrenal nodule who had pituitary ACTH-dependent disease with impaired dexamethasone suppressibility. This case provides evidence suggesting that in some cases of Custhing's syndrome may begin first as a pituitary process which can evolve in time into one of autonomously functioning nodular adrenal hyperplasia.

Klinefelter syndrome is one of the most common forms of primary hypogonadism and infertility in males. It is a clinical syndrome consisting of gynecomastia, azoospermia, and increased urinary excretion of follicle-stimulating hormone. Fequency of diabetes mellitus, emphysema, asthma, breast cancer increase in Klinefelter syndrome. We report a 16-year-old male patient with impaired glucose tolerance in association with Klinefelter syndrome, which was confirmed by chromosome analysis. The mechanism of impaired glucose tolerance in this patient was peripheral insulin resistance which clarified by euglycemic hyperinsulinemic clamp test (J Kor Soc Endocrinol 13:495-500, 1998).

61 year-old man with malnutrition and ascite was diagnosed to have Menetrier's disease by gastrofiberscopy and UGIS. Work-up showed classic menetriers disease with enlarged gastric rugae and hypoalbuminemia due to protein-losing gastropathy. 50 days after medical conservative treatement, total gastrectomy was performed in order to improve hypoalbuminemia. Microscopically there was a increased number of mucous cell involving the parietal and chief cell. We consider it mixed mucous-glandular cell type hyperplasia by Mings classification. The pathogenesis and pathophysiology of the disease are poorly understood. Indeed, there is sti]1 controversy regarding its classification, cause and management. A brief review of classification, etiology, pathophysiology, classical pictures and management of Menetriers disease is presented.
