In patients with unilateral condylar hyperplasia, increased length of the condylar neck causes deviation of the mandible to the opposite site, resulting in facial asymmetry, but the arch form and general contour of the displaced mandible is approximately symmetric. So, the unilateral condylectomy have been prefered surgical method among the surgeons. The purpose of this study is to analyze the postoperative results comparatively following two different surgical methods, condylectomy and ramus surgery, in unilateral condylar hyperplasia. Case of 6 patients with the unilateral condylar hyerplasia were analyzed in this study, 3 case of the condylectomy only, 3 cases of the ramus surgery, Clinical and radiographic evaluations were tried for comparison. In conclusion, comparative results between two groups did not show any significant difference,but we confirmed that unilateral condylectomy could be a excellent surgical methods in unilateral condylar hyperplasia thinking over the unique morphological characteristics of it.

Lacquer(rhus) could induce delayed hypersensitivity reactions, mainly contact dermatitis in sensitized patients. We experienced two cases of toxic epidermal necrolysis and acute generalized exanthematous pustules which were induced after ingesting food including lacquer. A 51-year-old man suffered from generalized rash with Nikolsky sign and fever during 3 days before visit. Hemorrhagic oral mucositis and conjunctival injection were observed. Hepatic enzyme and bilirubin were elevated. He ingested chicken cooked with lacquer 2 weeks ago. He experienced itching sense after that, and he also has twice history of itching after ingested same food. We diagnosed him as lacquer induced toxic epidermal necrolysis. With treatment of intravenous systemic corticosteroid and dressing, he recovered without severe complication. A 53-year-old woman suffered from generalized itching and rash during 6 days. 2 weeks ago, she ingested sprout of lacuquer. Itching was developed from chin in next day to general body in one week. Dermatitis at right fiank, erythematic rash on back and multiple pustules on anterior chest were observed when she visited hospital. We diagnosed her as acute generalized exanthematous pustules. With treatment of oral systemic corticosteroid and antihistamine, she recovered without severe complication. All of two patients rejected patch test with lacquer and we educated the patients to avoid lacquer and lacquer including materials and food. Mango also should be taken care for cross-reaction.

To improve the luminescence characteristics of high-efficiency alternating-current plasma display panels (AC-PDPs), we developed a new hoof-type electrode structure, and we studied the spatiotemporal behavior of the density of the excited Xenon atom in the 1s5 metastable state via laser absorption spectroscopy. Using this structure, the maximum density of the excited Xenon atom per cell was improved by 2.4 times that when the conventional electrode structure was used.

The immunoprotective nature of the testes has prompted numerous investigations for supportive roles of Sertoli cells (SCs) during allogeneic or xenogeneic cellular grafts. These potential benefits afforded by SCs could be achieved by obtaining enough number of SCs that have most proliferative activity in primary isolation. To investigate the effects of neonatal hypothyroidism on SC proliferation and maturation, we examined the expression changes of cyclin-dependent kinase inhibitor (p27<SUP>KiP1</SUP>), androgen receptor (AR), and testicular transcription factors (WT1 and GATA-4) by immunohistochemistry and western blot analysis in 6-propyl-2-thiouracil (PTU)-induced hypothyroidal mice. The expression of p27<SUP>KiP1</SUP> was low in rapidly proliferating testicular cells but had increased strongly in non-proliferating periods. Delayed expressions of p27<SUP>KiP1</SUP> on testicular cells of hypothyroidal mice were consistent with the expression patterns of AR and WT1. Whereas GATA-4 expression was kept a constant in all groups. These results indicate that chemically-induced neonatal hypothyroidism may be a useful approach for improving cellular yields and proliferative activity.

Eyelid tumors, including metastatic lid tumors, present clinically as recurrent chalazia, multicentric nodules, ulcerated lesions, diffuse swelling, or chronic blepharoconjuntivitis. Lid tumors consist of benign lesions(69%) and malignant lesions(31%). Basal cell carcinoma and squamous cell carcinoma account for 92% of the malignant lesions. Metastatic lid disease was found to be of rare occurence, accounting for 0.1% of all lid lesions and 0.3% of malignant lid lesions. We report a case of metastatic lid carcinoma of stomach cancer. A 60-year-old man developed a painless, slow-growing nodular lesion of his right lower eyelid. Excisional biopsy revealed metastatic undifferentiated adenocarcinoma. We believe this is the first case in Korean literature.
