This study was performed to investigate the distribution and magnitude of stress at supporting tissue of abutment teeth and residual ridge tissue with remaining unilateral posterior teeth. Four types of removable partial dentures that included clasp retained removable partial denture, attachment retained removable partial denture, telescopic removable partial denture, and swing-lock partial denture were designed, and strain gauge was used for stress analysis. Each prosthesis was subjected to simulated vertical and oblique load. The following conclusions were drawn from this study. 1. The clasp retained removable partial denture generally distributed simulated vertical force more evenly to the supporting structure. 2. The stress at buccal side of 1st premolar was the lowest in swing-lock partial denture and that was highest in attchment retained removable partial denture. The stress at lingual side of 1st premolar was the lowest in telescopic partial denture. 3. In clasp retained removable partial denture, stress was lower at load site and ridge crest at midline, but it was higher at lst premolar area on vertical load. 4. In attachment removable partial denture, stresses at buccal side of 1st premolar, lingual side of 1st premolar on vertical load, and ridge crest at midline on oblique load were higher. 5. In telescopic removable partial denture, stress at lingual side of 1st premolar was the least in all removable partial dentures, but the stress at load site was higher. 6. In swing-lock removable partial denture, stress at buccal side of 1st premolar was the lowest, and stresses at load site and distal end of residual ridge crest were higher.

This study aimed at assessing the usefulness of paraffin wax sections for demonstration of ER(estrogen receptor) and PR(progesterone receptor), using brief microwave processing rather than proteolytic predigestion. The receptor status of a breast cancer is often into consideration when planning treatment nowadays. As biochemical receptor assays require large amount of fresh tumor tissue and are not always available for all tumors, pathologists are now increasingly asked to provide a service for the assessment of the receptor status in tissue routine sections. Until recently, immunohistochemical demonstration of receptors was used in frozen sections. Therefore, routinely processed paraffin wax sections of 25 cases of breast carcinoma with known ER and PR concentrations, estimated by the standard DCC(dextran-coated charcoal) biochemical assay, were examined using the ABC immunoperoxidase technique. The results were assessed semiquantitably, using a five grade scoring system. Of the 25 cases examined, with DCC cutoff point being <10 fmol,71% and 75% in positivity of each ER, PR receptor is concordant. Statistic analysis demonstrates high relationship between scoring system of IH method and DCC value in ER (R=0.6061, p=0.001) and PR (R=0.5832, p=0.001). The IH method can provide easily assessed reliable positive information about ER, PR status of breast carcinoma using routinely processed paraffin wax sections.

Leiomyoma is commonly found in the female genital tract, but occurrence in the urinary bladder is very rare with only 235 cases reported in the literature. These tumors have been classified as intravesical (63%), intramural (7%) and extravesical (30%) depending on the direction of the growth. We report a case of intravesical leiomyoma of the urinary bladder in a 36 year-old woman who exhibited dysuria and urinary retention. The gross and microscopical findings of leiomyoma of the bladder are similar to those of the uterus. Immunohistochemical stains for estrogen receptor (ER) and progesterone receptor (PR) revealed diffuse nuclear staining in smooth muscle cells, supporting the hypothesis of hormonal influence in tumorigenesis.

Pulmonary tumors exhibiting neuroendocrine differentiation are classified as typical carcinoid, atypical carcinoid, and small cell lung carcinoma(SCLC). Travis et al. proposed a fourth category of large cell neuroendocrine carcinoma, which is characterized by light microscopic neuroendocrine appearance, cells of large size, polygonal shape, low nuclear cytoplasmic ratio, coarse nuclear chromatin, with prominent nucleoli high mitotic rate and frequent necrosis; and neuroendocrine features by immunohistochemistry or electron microscopy. High grade neuroendocrine carcinoma (LCAC-NE) revealed aggressive clinical course. We report two cases of neuroendocrine tumors of the lung characterized by a trabecular pattern of large pleomorphic cells with frequent mitoses and wide necrosis. The frequent metastatic sites of atypical carcinoid were liver, bone and brain. One of our case is presented, at first, as an ovarian mass, which shows multifocal rosettes and revealed metastasis from lung. Both cases expressed neuroendocrine differentiation by light microscopy and immunohistochemistry. However clinical neuroendocrine symptom were not present.

8.Identifying Predictors of Non-Suicidal Self-Injuries in Individuals with Eating Disorders

Purpose:
Nearly one third of all patients with an eating disorder (ED) present with non-suicidal self-injury (NSSI). Although it is necessary to pay attention clinically to NSSI in ED patients due to an increased suicidal risk, there are limited data on potential predictors of NSSI in ED. We conducted this study to uncover predictors of NSSI in ED.
Materials and Methods:
A total of 1355 ED patients who visited an ED clinic was evaluated through structured interviews by psychiatrists. The demographic and clinical characteristics of ED patients with NSSI (NSSI group) and ED patients without NSSI (non-NSSI group) were analyzed to identify potential predictors of NSSI in ED.
Results:
Among all ED individuals, 242 (17.9%) reported a history of NSSI. Compared to the non-NSSI group, the NSSI group reported more severe eating symptomatology, more comorbid psychiatric disease, and more suicidal risk. Comorbid alcohol use disorder, depressive disorder, purging behavior, history of suicide attempt, and rumination symptoms were uncovered as predictors of NSSI in ED.
Conclusion
The findings of the study are meaningful in that they highlight predictors of NSSI in ED in a large clinical sample. Understanding risk factors of NSSI and offering appropriate interventions are important to preventing suicidality in ED.

PURPOSE: Both antithrombin III(ATIII) and Gabexate mesilate(Foy) are effective for the treatment of disseminated intravascular coagulation(DIC). However, their mechanisms of action are slightly different, and combined effect of ATIII and Foy in premature infant with DIC has not been studied. We evaluated therapeutic efficacy of treatments with either ATIII or Foy alone or both in combination. METHODS: We studied 23 premature infants of gestational ages between 30 and 36 weeks with DIC. Group A(n=10) was treated by ATIII only, Group B(n=7) by Foy only and Group C(n=6) by both ATIII and Foy. Three groups were compared for volume of blood sampling and transfusion and hematologic data. RESULTS: Improvement of hematologic data(platelet, PT, aPTT, fibrinogen, FDP) was not significantly different among 3 groups. The mean volume of blood sampling during 5 days of treatment was 30 mL, 22.5 mL, and 30 mL, respectively. The mean volume of packed RBC transfusion was 12.8 mL, 9 mL, and 2.5 mL, respectively: and mean volume of platelet transfusion was 25.9 mL, 10 mL, and 0 mL, respectively, showing no significant statistical difference. But the mean volume of FFP transfusion was 141 mL only in group B, significantly higher compared to other groups. CONCLUSION: The combination therapy of ATIII and Foy significantly decreased the volume of FFP transfusion and may be more effective than monotherapy with ATIII or Foy alone in DIC of premature infant.
