Ants(Family Formicidae) are very successful organisms occuring in trernendous numbers worldwide in terrestrial habitats. All ant species may bite, and on species sting. 48 species in 26 genus have been reported in Korea, but only systemic reaction induced by the anti Brachyponera chinersis, has been reported in the Korea terature. A 48 year old man was stung on the neck, abdomen, and dorsum of the hand by flying stinging ants. He experienced moderate pain, burning and itching sensation. Clinical course and histopathologic findings of the lesions caused by the stinging ant was observed without specific treatment. The stinging ants collected from t,he patient.s skin and his house were identified as Euponera chosensis belonging to Subfamily Ponerinae. To the best of our know ledge, this is the first clinical repor of the insect sting by Euponera chosensis in the Korean literature.

This study was investigated to compare the staining resistance of soft denture liners. Specimens wee made of Coe-soft. Coe-Comfort, Soft-liner, Visco-gel, and were stored in 1% methyleneblue solution for 24 hours. The amounts of color change before and after treatment with mono-poly and thermocycling were measured by colorimeter(TC-6FX, Tokyo Denshoku Co. Ltd, Japan) for evaluation of staining resistance. The following conclusions were drawn from this study. 1. The staining resistance of Visco-gel was increased, but there was no changer of staining resistance in Coe-soft, Coe-comfort, and Soft-liner after treatment with monopoly. 2. The staining resistance of the Coe-comfort was the least in all soft denture liners. 3. The staining resistance of Visco-gel and Soft-liner were decreased after thermocycling.

Soft denture liners or conditioners may be valuable therapeutic materials. The life of these liners is short and varies, but it can be extended by the use of a mono-poly(polymethyl methacrylate coating material). This study determined whether coating three temporary soft denture liners with mono-poly affected the resiliency of soft liners, and evaluated the ability of mono-poly to prevent water absorption and alcohol loss from the underlying soft liners. 20x12mm cylindrical specimens of Coe-Soft, Soft-Liner, Coe-Comfort soft lining materials were made and divided into two groups of mono-poly uncoated(control) and mono-poly coated specimens. Specimens were immersed in water and compressed on an instron universal testing machine and weighted at initial, 24 hours, 1 week, 2 weeks, and 4 weeks. resiliency was determined by measuring the energy absorbed by the soft liners when stressed to a specific yield point. Mono-poly coating significantly increased the resiliency of the Soft-Liner, but had no effect on the other soft liners. Among the 3 soft liners, Soft-Liner showed the hightest resiliency and modulus of elasticity. The weight loss in Soft-Liner was the least among the 3 liners, and the weight loss in Coe-Soft was decreased by monopoly coating.

The association rate of antibody with antigen has been reported to be greatly increased by lowering ionic strength. Low-ionic strength salt solution(LISS) method has been used for the detection of various alloantibodies. To investigate the sensitivity of LISS in indirect antiglobulin test, a comparison study of LISS with saline and albumin methods was conducted. A total of 32 patients' samples requested for indirect antiglobulin test were evaluated. Out of 32 patients with clinical immune hemolytic anemia, 11(34.3%) were positive in 37 degrees C saline antiglobulin test, 18(56.2%) in albumin antiglobulin test, 23(71.8%) in LISS antiglobulin test respectively. These results were statistically analyzed using non parametric Page's test for ordered alternatives. LISS method is more sensitive than 37 degrees C saline method or albumin method significantly (p<0.01).
