We investigated on how the nature of vehicles influenced on the efficacy of mo isturizer s, cutaneous hydrat,ion, physical property and roughness. Hydration was measured with corneometer, physical property with fermometer, and mughness with image analyser. Used vehicles were as follows : hydrous gel, vater in oil(W/0) emulsion, oil in water(0/W) emulsion. I.Jsed moisturizers were as follows . glycerine, polypeptide and sodium lactat,e, hyaluronic acid-triethanolamine, sodium lactate, pvopylene glycol, The results are summarized as follows : 1. The increment of the hydration effect according to vehicles was in this order. C/ W emulsion, W/0 emulsion, hydrous gel(After 2 hours). 2. The increment of extensibility as physical property was correlated to the in crcment, of hydration effcet(r=0.924). 3. It was shown that, the roughness was decreased after treatment of all mo isturizers except propylene glycol but, there was not significant st.atistically and alsa was no meaningful difference among the vehicles. 4. Among t,he moisturizers, glycerine was superior to other moisturizers on the hydration effect and extensihility. We conclude that 0/W emulsion was suitable vehicle on cutaneous hydration effect and hydration effect is proportion to the increment of flexibility.

A 34-year-old Korean man presented with a 3 week history of a yellowish eczema like patch on the left thigh. Sixteen months prior, he was diagnosed with polymorphie r eticulosis of the left nasal cavity. The patient, refuse<3 conventional radiation therapy and took herbal medication and diet therapy instead. Biopsy of the nasal cavity, hard palate and left thigh lesians showed extensive necrosis and polymorphic infiltrates of atypical lymphocytes with angiodestructive invasion. Irnmunohistochemical study of left thiyh lesion showed strong CD2 positivity con sistent with the diagnosis of peripheral T cell lymphorra.

BACKGROUND: In animal models of cerebral ischemic-reperfusion has been shown to have a beneficial effect. The object of this study is to compare the effect of pathologic findings between normotheimic and moderate hypothermic group. METHODS: We investigated the effect of moderate hypothermia induced 1 hour after transient(10 min) both carotid artery occlusion on the extent of ischemic-reperfusion cell damage in Mongolian Gerbil model. The terminal deoxyribonucleotidyl transferase (TdT) -mediated biotin-16-dUTP nick-end labelling(TUNEL staning) are used to detect apoptosis. RESULTS: 1. We suggest that Core body temperature is down to moderate hypothermia(30-32degrees C) beyond 10 minite by selective bain cooling method in Mongolian Gerbil model. 2. By light microscopy, ischemic-reperfusion damage were detected in the hippocampal CA1 pyramidal layer on the 3 day after transient ischemic insult, which showed chrosomal condensation and cytoplasmic eosinophilia. Ischemic-reperfusion cells were increased in the CA1 region on the 5 day. Apoptotic cells of the CA1 neurons seen by TUNEL staining than ischemic neurons seen by Hematoxylin-eosin staining were investigate 3 and 5 days after ischemic-reperfusion insult. CONCLUSION: We suggest that is not neuroprotective effects of Intraischemic(1 hour) moderate hypothermia in Gerbil brain global ischemic-reperfusion model.

Eccrine poromas mainly involve the non-hairy surfaces of the skin, however, have also been found on hair bearing areas. Pigmentation in the tumor cells is rare but has been mentioned in a few papers. The following case documents an example of a pigmented eccrine poroma which occurred in an unusual location; the posterior scalp.

OBJECTIVE: To introduce the frequency and segment analysis of in-stent stenosis for intracranial stent assisted endovascular treatment on complex aneurysms. METHODS: A retrospective study was performed in 158 patients who had intracranial complex aneurysms and were treated by endovascular stent application with or without coil embolization. Of these, 102 patients were evaluated with catheter based angiography after 6, 12, and 18 months. Aneurysm location, using stent, time to stenosis, stenosis rate and narrowing segment were analyzed. RESULTS: Among follow-up cerebral angiography done in 102 patients, 8 patients (7.8%) were shown an in-stent stenosis. Two patients have unruptured aneurysm and six patients have ruptured one. Number of Neuroform stents were 7 cases (7.5%) and Enterprise stent in 1 case (11.1%). Six patients demonstrated in-stent stenosis at 6 months after stent application and remaining two patients were shown at 12 months, 18 months, respectively. CONCLUSION: In-stent stenosis can be confronted after intracranial stent deployment. In our study, no patient showed symptomatic stenosis and there were no patients who required to further treatment except continuing antiplatets medication. In-stent stenosis has been known to be very few when they are placed into the non-pathologic parent artery during the complex aneurysm treatment, but the authors found that it was apt to happen on follow up angiography. Although the related symptom was not seen in our cases, the luminal narrowing at the stented area may result the untoward hemodynamic event in the specific condition.

OBJECTIVE: The aim of this study was to conduct three-dimensional finite element analysis of individual tooth displacement and stress distribution when a posterior retraction force of 200 g was applied at different positions of the retraction hook on the transpalatal arch (TPA) of a molar, and over different lengths of the lever arm on the maxillary anterior teeth in lingual orthodontics. METHODS: A three-dimensional finite element model, including the entire upper dentition, periodontal ligaments, and alveolar bones, was constructed on the basis of a sample (Nissan Dental Product, Kyoto, Japan) survey of Asian adults. Individual movement of the incisal edge and root apex was estimated along the x-, y-, and z-coordinates to analyze tooth displacement and von Mises stress distribution. RESULTS: When the length of the lever arm was 15 mm and 20 mm, the incisal edge and root apex of the anterior teeth was displaced lingually, with a maximum lingual displacement at the lever arm length of 20 mm. When the posterior retraction hook was on the root apex, the molars showed distal displacement. When the length of the lever arm was 20 mm, anterior extrusion was reduced and the crown of the canine displaced toward the buccal side, in which case, the retraction hook was on the edge, rather than at the center, of the TPA. CONCLUSIONS: The results of the analysis showed that when 6 anterior teeth were retracted posteriorly, lateral displacement of the canine and lingual displacement of the incisal edge and root apex of the anterior teeth occur without the extrusion of the anterior segment when the length of the lever arm is longer, and the posterior retraction hook is in the midpalatal area.
