OBJECTIVE: Endometriosis is a disease affecting a large population of women all over the world. A local sterile inflammation occurs in the peritonel cavity of patients with endometriosis. It suggests that immunological events play a major role in the pathogenesis of endometriosis. We have studied the levels of serveral T cell and monocyte derived cytokines, especially IL-6 (promoter of immune response) and IL-10 (inhibitor of immune response), in the peritoneal fluid of patients with endometriosis to characterize the change of immune response that occurs at the site of endometriosis. Method: This study was performed in Hallym university hospital from October, 1997 to October 1998 and enrolled 29 women with gross or microscopic findings of minimal to severe endometriosis in case group, and 28 women without visual evidence of pelvic endometriosis and with benign gynecologic disease in control group. IL-6 and IL-10 levels in the peritoneal fluid were determined using commercial ELISA and compared between endometriosis and controls and between fertile and infertile women with endometriosis and according to the revised American Fertility Society classification. RESULT: IL-6 was higher and IL-10 was lower in the peritoneal fluid of endometriosis group than of control group. Cyclic variations in the IL-6 concentrations were seen in endometriosis group : the concentrations in the secretory phase were significantly higher than those in the proliferative phase. In endometriosis group, IL-6 concentrations of infertile women were higher than fertile women. Both IL-6 and IL-10 in the peritoneal fluid of endomtriosis group did not show significant correlation according to r-AFS stages. CONCLUSION: Increased IL-6 and decreased IL-10 levels in the peritoneal fluid may be related to infertility and pathogenesis in the endometriosis, suggesting that partially contribute to the disturbed immune regulation observed in endometriosis.

The purpose of the present study was to examine dental hygienists' perception of the current national practical examination. This research was performed using 199 self-reported surveys answered by professors of dental hygiene studies and clinical dental hygienist. Frequency analysis, chi-square tests, and analysis of variance were performed by using IBM SPSS Statistics ver. 20.0. The results revealed that many of the respondents consider the current national practical examination to be neutral. They did not think that the current national practical examination questions are useful for assessing occupation-centric integrated clinical practice ability and counseling techniques for patient intervention. The professors of dental hygiene studies believed that among the research tasks required as mentioned in the national practical examination questions, dental polishing and tooth brushing education are of paramount importance, whereas clinical dental hygienists believed that ultrasonic scaling is the most important (p<0.05). Most of the professors of dental hygiene studies reported that they conducted skills education for dental polishing and tooth brushing education, while most of the clinical dental hygienists reported that tasks actually performed in the clinic included impression taking, model fabrication, ultrasonic scaling, and explaining treatment precautions (p<0.05). Therefore, these tasks can be effectively carried out with the improvement of the national dental hygienist practical examination.

The objective of this study was to fabricate hydroxyapatite (HA) containing titania layer by HA blasting and anodization method to obtain advantages of both methods and evaluated biocompatibility. To fabricate the HA containing titania layer on titanium, HA blasting treatment was performed followed by microarc oxidation (MAO) using the electrolyte solution of 0.04 M β-glycerol phosphate disodium salt n-hydrate and 0.4 M calcium acetate n-hydrate on the condition of various applied voltages (100, 150, 200, 250 V) for 3 minutes. The experimental group was divided according to the surface treatment procedure: SM (simple machined polishing treatment), HA, MAO, HA+MAO 100, HA+MAO 150, HA+MAO 200, HA+ MAO 250. The wettability of surface was observed by contact angle measurement. Biocompatibility was evaluated by cell adhesion, and cell differentiation including alkaline phosphatase activity and calcium concentration with MC3T3-E1 cells. The porous titanium oxide containing HA was formed at 150 and 200 V. These surfaces had a more hydrophilic characteristic. Biocompatibility was demonstrated that HA·titania composite layer on titanium showed enhanced cell adhesion, and cell differentiation. Therefore, these results suggested that HA containing titania layer on titanium was improved biological properties that could be applied as material for dental implant system.

The present study assessed the effects of Rapid Maxillary Expansion on head posture and hyoid bone position. For this study, 32 Angle's class III patients - hellman 3c ~ adult stage, mean age 12y9m ? were selected divided into two group, A,B according to craniocervical angulation. Craniocervical angulation Increased in Group A and decreased in Group B after the therapy. And 23 Angle's class I persons ~ same hellman stage, mean age 12y7m ~ were selected for the control group. Cephalometric analysis of skeletal pattern, pharyngeal space, head posture, hyoid bone position was performed. The result were as follows, 1. Comparison of skeletal pattern and pharyngeal space 1) All two group(A,B) had Mandibular plane inclined inferiorly and no pharyngeal space change was observed after RME therapy. 2) Skeletal pattern and pharyngeal space of Group A, B were normal before and after treatment. 2. Comparison of head posture 1) Craniocervical angulation of Group A was increased after treatment. That of Group B was decreased and mandibular plane was inclined inferiorly after treatment. 2) Before treatment, craniocervical inclination was normal in Group A but larger than normal in Group B. After treatment, all two groups(A, B) had normal craniocervical angulation. 3. Comparison of hyoid bone position 1) After treatment, long axis of hyoid in Group A, B was not changed. Antero- posteriorly, hyoid position was changed posteriorly in Group A but no change was founded in Group B after treatment. Vertically, hyoid bone position were not changed in two group except increase in APHFH in Group A after treatment. 2) Long axis of hyoid bone was normal in Group A, B before and after treatment. Anteroposteriorly, hyoid bone position was more anterior than Group B, C before treatment but all the position of two groups had normal position after treatment. Vertical position of hyoid bone was normal in all two groups before and after treatment.

Great efforts have been expended to compensate for nerve gap in the repair of a peripheral nerve injury. And yet, this nerve gap presents a great problem in surgical management. End-to-end anastomosis is most frequently used for repair of peripheral nerves, but the main problem is tension at the suture site. The purpose of this experiment is to observe the relationship between the tension and the nerve healing, when stretching is applied to the suture site of the peripheral nerve trunk. We used 25 rabbits of both sexes divided into 5 groups according to the nerve gap and the period of immobilization for this study. Gross and histological examination were used to compare the results of end-to-end suture under a tension and suture without tension. We concluded that: 1. The best results were obtained when end-to-end suture was done without tension. 2. Direct suture under a tension produced the results quite inferior to that of the suture without tension. 3. Better results were obtained from the group of immobilization, at least, for 4 weeks among the tension group. 4. Immobilization period may be prolonged according to the degree of the tension affecting the suture site. 5. Tension at the suture site causes proliferation of connective tissue.
