Pleomorphic adenoma is the most common of all salivary gland tumors, constituting over 50 per cent of all cases of tumors, and approximately 90 per cent of all benign salivary gland tumors. Since the term mixed tumor' was introduced by Broca for its dual origin of epithelial and mesenchymal elements, the term plemorphic adenoma suggested by Willis characterizes closely the unusual histologic pattern of the lesion. The parotid gland is the most common site but it may occur in any of the salivary glands. It is somewhat more frequent in women and in the fourth to sixth decades, but they are also relatively common in young adult and have been known to occur in children. Treatment of choice is surgical excision. Adequate surgery with safe margin reduce its recurrence rate. We represent a case of pleomorphic adenoma with literature review in 65-year old male occured in the palate. The lesion was successfully treated by surgical excision.

The DMA(Dimethylamine) gas sensors were fabricated with the ZnO-based thin films grown by a RF magnetron sputtering method. We investigated the sensitivity and response time according to temperature variation and DMA gas concentration. The ZnO-based thin film sensors sputtered in oxygen atmosphere showed higher sensitivity than those sputtered in argon atmosphere. The ZnO-based thin film sensors doped with Al_(2)O_(3), In_(2)O_(3) and V_(2)O_(5) and sputtered in oxygen atmosphere showed the maximum sensitivity of 218(working temperature, 250 ℃, DMA gas, 160 ppm) and speedy response time. The ZnO-based thin film sensors doped with Al_(2)O_(3), In_(2)O_(3), TiO_(2) and V_(2)O_(5), sputtered in oxygen atmosphere and aged at 330 ℃ showed the maximum sensitivity of 156(working temperature, 250 ℃, DMA gas, 160 ppm).

There are so many reasons why patient selects orthodontic and orthognathic treatment, but most of them want functional improvement. Sometimes patients are not satisfied though functionally improved. It is apparent that they want esthetic improvement too. Satisfaction and happiness are influenced by on self-evaluation, emotional state, expectation and so on. Clinicians have difficulty in estimating and treating the patients by psychological norm. Therefore, we study the relation between orthognathic surgery and aesthetics.

김계엽,김태열,김경윤 東新大學校 2003 論文集 Vol.13 No.-

The purpose of this study was to investigate and analyze effect of needle transcutaneous electrical nerve stimulation with the change of immunohistochemistry method through the change of c-fos in spinal dorsal horn(pre, 4, 8, 12 and 24h). An experimental arthritis induced in 100 Sprauge-Dawley rats with a mixture 3% carrageenan and 3% kaolin(0.1 ㎖ in sterile saline) into the joint cavity of one knee. Each group was randomly divided into four groups; Group Ⅰ : control group, Group Ⅱ : arthritic limb-induced group, Group Ⅲ : Needle TENS application on ipsilateral arthritic limb(2 Hz, 200 μs, 20 min) group, Group IV : Needle TENS application on contralateral arthritic limb(2 Hz, 200 μs, 20 min) group. The results of this study were as follows: 1. In naked eyes opinion, c-fos immunoreactive positive neurons are increased markedly 4 hours after arthritis limb-induced in Rexed Ⅰ, Ⅱ of superficial dorsal horn. Group Ⅲ and group Ⅳ are more decreased than Group Ⅱ at 8 hours after arthritis limb-induced. 2. The c-fos immunoreactive positive neurons after application needle like transcutaneous electrical nerve stimulation on arthritic limb-induced model group are more decreased than only arthritic limb-induced group. 3. The number of c-fos immunoreactive positive neurons in superficial dorsal horn was decreased markedly 4 hours after arthritis limb-induced. Group Ⅲ and group N are more decreased than Group Ⅱ at 8 hours after arthritis limb-induced(p<0.001). Specially Group Ⅲ showed the most significantly effect at 8 hours(p<0.01). The above results suggest that needle transcutaneous electrical nerve stimulation effectively reduced in arthritic limb-induced model. In addition, greatly decreased the number of c-fos neurons explains needle transcutaneous electrical nerve stimulation application on ipsilateral arthritic limb is more effective than that on contralateral arthritic limb.

Cyclosporin A and verapamil were tested using MTT assay to evalute the modification effect on the resistance to adriamycin in a human lung cancer cell line(PC-14) and its resistant subline(PC-14/A). PC-14/A was derived by the continuous exposure of PC-14 to incremental concentrations of adriamycin. PC-14/A was 2.5 times more resistant to adriamycin in terms of ICso than PC-14. Cyclosporin A alone, at a concentration of 2.5㎍/㎖, inhibited the growth of PC-14 to 68.3%. 2.5㎍/ ㎖ and 5.0㎍/㎖ of cyclosporin A showed an increase in the cytotoxicity of adriamycin (p<0.01) with 5.0㎍/㎖ being greater than 2.5㎍/㎖(p<0.01). Excluding the direct cytotoxic effect, however, cyclosporin A did not increase in the sensitivity of PC-14 to adriamycin but only showed an additional cytotoxic effect with adriamycin. Verapamil (up to 6.0㎍/㎖) did not inhibit the growth of PC-14. 3.0㎍/㎖ of verapamil did not increase the cytotoxic effect of adriamycin. The combination of cyclosporin A and verapamil with adriamycin enhanced the cytotoxicity of adriamycin, but the result was similar to that of cyclosporin A with adriamycin. 5.0㎍/㎖ of cyclosporin A modified the adriamycin resistance of PC-14/A(SR, 3.2). However, 3.0㎍/㎖ of verapamil did not significantly reverse the adriamycin resistance of PC-14/A. The modified effect of the combination of 5.0㎍/㎖ of cyclosporin A and 3.0㎍/㎖ of verapamil was similar to that of 5.0㎍/㎖ of cyclosporin A alone in PC-14/A. These results demonstrate that cyclosporin A has an additional cytotoxic effect with adriamycin in PC-14 and PC-14/A and has overcome the acquired resistance to adriamycin in PC-14/A. They also suggest that cyclospoin A may have the therapeutic potential in the treatment of human lung cancer.

The purpose of the present study was to investigate the effect of absorbable membrane (BioMesh®) on bone regeneration in the rabbit by evaluating biodegradability, biocompatibility and bone regenerative capacity. Eight rabbits, weighing about 2kg, were used. Two bone defects, 8 mm in diameter and 7 mm in depth, were made. In the experimental group, the bone defect was covered with BioMesh® absorbable membrane. In the control group, induced spontaneous healing. The rabbits were sacrificed at 2, 4, 6, and 8 weeks after the operation. Radiographic and microscopic examination were performed. Results obtained were as follows: After 2 weeks, proliferation of the fibrous tissue was observed in the control group, but the newly formed cartilage and more active bone formation were noted in the experimental group. After 4 weeks, the new bone formation appeared in the control group, and in the experimental group, the bone trabeculi were densely aligned and matured. After 6 weeks, complete resorption of the BioMesh® membrane occurred in the experimental group. Both experimental and control group acquired dense osseous coverage, after 8 weeks. These results suggest that the BioMesh® absorbable membrane contributes new bone formation by guiding bone regeneration in the early stage.
