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.

The p53 gene, one of the tumor suppressor genes, is believed to play an important role through mutation and overexpression in the progression of various human malignant tumors. To compare the p53 mutation status between the primary and metastatic lesions of breast cancers and to investigate the mutational pattern of p53, immunohistochemistry (IHC) and polymerase chain reaction and single strand conformational polymorphism (PCR-SSCP) were performed in 25 cases of breast cancers with paraffin embedded tissue. Mutant protein products or point mutation were detected through IHC or PCR-SSCP method. And flow cytometrical (FCM) analysis were performed in the same paraffin blocks to correlate the DNA ploidy and p53 mutation. The following results are summarized. 1. The detection of the p53 gene mutation and overexpression of the p53 protein were measured in 40% and 48%, respectively, in 25 primary tumors, either or both methods was detected in 64%. 2. A concordance rate of the p53 protein expression between the primary and metastatic lesions of 25 breast cancers was 100%, but the concordance rate of the p53 gene mutation was 72%. 3. The correlation between the p53 mutation and the DNA aneuploidy was not statistically significant (p=0.38) 4. A p53 mutation by IHC or PCR-SSCP was more frequently detected in grade III breast cancers than in grade I or II. 5. Among 5 to 9 exons of the p53 gene, exon 7 was the most frequent mutation spot in this study. 6. Additional mutation of the p53 gene was developed in the three metastatic lesions. With the above results it is suggested that the p53 protein overexpression by immunohistochemistry is not correlated with the p53 mutation by PCR-SSCP. The p53 mutation pattern between the primary and metastatic lesions are not idenitical and an additional point mutation can occur in the metastatic lesion. The DNA aneuploidy is more frequently detected in the cases with the p53 protein overexpression than in the p53 protein negative, but it is not statistically significant.

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.
