With development of immunochemical methods for anlysis of serum proteins, quantitative determination of serum immunoglobulin levels and purification of them have been made possible in recent years. There are numerous reports about immunoglobulin levels in various diseases. A search of the literature reveals very few reports of quantitative immunoglobulin determinations in allergic dermatoses. The present study was conducted to find quantitative changes of serum immunoglobulins in a few allergic dermatoses. To quantify the IgG, IgA and IgM, one hundred and two sera were analysed form 30 normal control group, 30 contact dermatitis patients, 12 stopic dermatitis patients and 30 urticaria patients by modified Oudin's capillary tube method. The results are as follows. 1.In contact dermatitis the IgG was significantly increased to compare with control group(p<0.01) 2.In atopic dermatitis the IgA was significantly increased to compare with control group(p<0.01) 3.In urticaria the IgG was increased (p<0.05) 4.The IgM has no differences between allergic dermatoses and control group.

Accurate reproduction of intraoral tissue is essential in the fabrication of fixed prosthesis. This selection of impression material and method is very important. In this study, vinyl polysiloxane type impression material Panasil was used. Three impression methods ; one-step technique, individual tray technique, and individual tooth tray technique using the vinyl polysiloxane type bite registration material Futar Occlusion, were used to take horizontal and vertical impression. Improved stone models were fabricated. The amount of occlusal surface discrepaneies, interabutment distance discrepancies, amount of marginal defect were evaluated with the X-PLAN360d and photoscanning. The results were as follows. 1. There was no significant difference in occlusal surface according to the directions and techniques of impression taking. 2. There was no significant difference in interabutment distance discrepancies according to the directions and techniques of impression taking 3. There was no significant difference in marginal discrepancies according to the direction of impression taking but there was significant difference between one-step technique and individual tray technique, individual tooth tray technique (P<0.05). Taken together, these results suggest that individual tray technique and individual tooth tray technique are more accurate for impression taking than one-step technique.

Hemangiopericytoma is a rather uncommon neoplasm composed mainly of cells derived from the vascular pericytes of Zimmermann, which are normally found in close apposition to the endothelial cells of capillaries and postcapillary venules. Authors studied a case in which primary hemangiopericytoma located in the left orbit of a 54-year-old woman. Review of the literatures about incidence, clinical symptoms, histological features and biological behavior of the orbital hemangiopericytoma was presented.

Relining and rebasing are essential for long-term success and oral health in removable prosthodontics. Major features of failures between metal base and relining resins are adhesive failure due to lack of chemical bonding. The purpose of this study was to find a better metal primer and metal surface treatment method that enhance the bonding strength with relining resin materials. The surfaces of ticonium alloys were treated with 25micrometer sandblasting (Group A), stone wheel (Group B), stone wheel and EZ oxisor (Group C), 75micrometer sandblasting (Group D) and EZ oxisor application after 75micrometer sandblasting (Group E). They were subdivided into no primer application (Group I), MR bond application (Group II) and Metafast bonding liner (Group III). Then specimens were completed though being bonded with relining resins. The specimens were stored in 38degrees C water for 48 hours and tensile strength was measured using the universal testing machine. The results were as follows, 1. Primer application groups showed higher bond strength than no primer application group(p<0.05). 2. In comparison with primer application groups, MR bond group showed higher bond strength than Meta fast bonding liner application group(p<0.05). 3. In comparison with surface treatment methods. Bond strengths of group A and B were significantly different with group C, D, and E, and group C were significantly different with group D, and E in no primer application group(p<0.05). In primer application groups, group A, B, C were significantly different with group D and E(p<0.05). According to results of this study, Metal primer application and metal surface roughening were considered to be advantageous for relining of metal base dentures.

Acardic twining is a rare congenital anomaly, usually in monozygotic twins. This condition is characterized by the absence or rudimentary development of fetal hear, and associated with various anomaly(especially with anecephalus). The acardiac malformations are uniformly fatal in the affected twin, and mortality in the co-twin is as high as 55%. We recently experienced a case of acardius acephalus associated with a normal term male infant, so present with a brief review of the literature.

Purpose: Vaccine hesitancy is among the top ten threats to global health, and access to precise data on adverse events following immunization (AEFIs) is imperative to alleviate public concerns surrounding vaccines. This study aimed to present the overall trends of AEFIs reported in South Korea. Materials and Methods: We evaluated the trends of AEFIs using the Korea Institute of Drug Safety & Risk Management-Korea Adverse Event Reporting System database between January 2005 and December 2017. AEFIs were classified into five categories to evaluate associations between vaccines and AEFIs through a case-non-case study: neurologic reactions, general systemic reactions, local reactions, allergic reactions, and others. Results: Among 54378 reported adverse events (AEs) associated with all vaccines approved in South Korea, more than half (56.7%) occurred following influenza vaccination, followed by the pneumococcal (11.6%) and Bacillus Calmette-Guérin (BCG) vaccines (5.0%). After immunization with most vaccines, general systemic reactions were most common, followed by local and neurologic reactions. Adjusted reporting odds ratios were calculated for all neurologic, general, local, and allergic reactions: of all vaccines, rotavirus [neurologic 2.43, 95% confidence interval (CI), 2.25–2.62], BCG (general; 2.20, 95% CI, 1.91–2.53), BCG (local; 3.15, 95% CI, 2.69–3.68), and Japanese encephalitis (allergic 2.38, 95% CI, 1.98–2.87) vaccines showed the highest values. Conclusion The majority of reported AEFIs were non-serious and mostly general systemic reactions. Sufficient knowledge on the AEFIs would secure public confidence on the safety of vaccines, thereby reducing public health burden from vaccine-preventable diseases.

Angiosarcoma is a rare malignant vascular tumor of endothelial cell origin. Most lesions of cutaneous angiosarcoma occur over the face and scalp. We experienced a case of angiosarcoma of the scalp in a 63-year-old man. Multiple pea-sized erythematous papules and nodules developed on the forehead 6 months ago. Thereafter, the lesions have extended to make violaceous, compressible and hemorrhagic plaques. On histologic examination, there were irregular, often anastomosing vascular channels lined by the atypical endothelial cells in the dermis.

We experienced a case of cutis laxa in a 17-year-old man. The skin showed diminished elasticity with loose folds, wrinkling, and sagging on the abdomen, lower back, and both inner thighs. There was no history of any inflammatory skit diseases prior to the appearance of the wrinkling. Family history revealed to be negative for the skin diseases showing wrinkling and laxity. The biopsy specimen from the skin of the abdomen showed shortened, fragmented elastic fibers in the dermis. The serum copper level was normal(92 ug/dl).
