We have found out the relationship of nanoemulsion containing nano vitamin C, E and propolis and gingival disease. We've confirmed effect of nanoemulsion through the experiment of in vivo and in vitro. We tested cell viability of gingival fibroblast cells by MTT assay and mRNA appearance of interleukin-1 beta, using mouse that was guided inflammation. Anti-microbacterial activity for Antibacterial effect's experiment was carried out by using S.aureus and E.coli. In addition, inflammation tissue has been observed with scanning electrical microscopy. In this study, expression of interleukin-1 beta was decreased after adding nanoemulsion containing nanovitamin C, E and propolis. We've also obtained good results from the test of Antibacterial effect against S.aureus and E.coli. Also, swelling of inflammation tissues observed by scanning electrical microscopy has gone down. In conclusion, we have gained confidence that nanoemulsion containing nano vitamin C, E and propolis has very high Antibacterial effect against bacteria in oral. And it made us guess that inflammation of gingival reduces after decreasing interleukin-1 beta. Thus, we expect that nanoemulsion containing nano vitamin C, E and propolis gives good effects to patient having gingival disease.

In clinical experience, patients complaining of knee joint pain which is not belong to the category of well documented causative diseases, such as rupture of menisci, collateral ligaments and so forth, have been encountered, Since the report of Mayedas chorda cavi articularis genu in 1918, internal derangement of knee due to rupture of plica synovialis has been presented from time to time, Numerous nomenclatures have been offered and various histologic and clinicopathologic features have been observed. Majority of uncomplicated plica synovialis are asymptomatic and respond well to conservative treatment, whereas in complicated cases operation is often inevitable. Here, a symptomatic case, due to rupture of plica synovialis mediopatellaris which was hard to differentiate from rupture of meniscus in clinical aspect and on operation field is reported with available references.

Congenital pseudarthrosis is frequently associated with various stigmata of neurofibromatosis, particularly Cafe-Au-Lait spots and,subcutaneous nodules and in these patients, it is noteworthy that the treatment is very difficult even with extensive operative approach. Also it is interesting to find many controversies on etiological relation between neurofibroma and pseudarthrosis, per se and even the existance of nerve element in and around the tissue of pseudarthrosis. A thirteen years old female patient with definite neurofibromatosis associated with congenital tibial pseudarthrosis treated by intramedullary nailing and massive bone graft is reported.

Deposition of monosodium urate crystal in joints and periarticular soft tissue is regarded as one of the characteristics of chronic gouty arthritis. In spine, however, only nineteen cases of tophaceous deposits have been reported to date suggesting the rarity of clinical symptoms secondary to involvement of spine. Authors report a case of spinal stenosis due to hypertrophy of ligament flavum with monosodium urate deposits. The patient was 65 years of age with chronic gouty arthritis who underwent a decompressive laminectomy at L4-5. At surgery, hypertrophied ligament flavum that was covered with chalky amorphous materials was noted without any evidence of radiologic features. Microscopically, a portion of ligament flavum had been focally destoryed by amorphous material deposits that were surrounded by a thin layer of mononuclear and giant cells along with occasional sprinkling of chronic inflammatory cells and negative birefringence on polarizing microscopy.

The purpose of this study is to present the results of the clerkship evaluation by the students using questionnaire, to discuss the problems revealed in performing the evaluation, and to find out the ways to improve the evaluation. In 2000, the evaluation has been conducted by the Department of Radiology, Seoul National University College of Medicine. The questionnaires filled-up by 97 junior students who completed the clerkship schedule of 2 weeks were analyzed in this study. The questionnaire consisted of 28 structured items with 5-grade scale each, the contents of which included the amount and level of the overall clerkship course and those of 5 subtypes of the clerkship(self-learning, student conference, student seminar, on-site clerkship, and small group discussion with faculty). In small group discussion, enthusiasm of each faculty, delivery effect, and difficulty of the contents were also evaluated. As a result, the most items were assessed to be slightly better than average(3 or 4 point of 5 scale). It was found that the small group discussion was most favored, whereas the student seminar was least favored. Faculty activity was also scored to be better than average. There were no significant differences among all faculty activity. The limitation of this study is failure of assessing the validity and reliability of the student response. In order to improve the evaluation, we should consider following four subjects: First, all the items are carefully developed to enhance the validity and reliability of the evaluation. Second, students should be fully informed of the objects of the evaluation before it is carried out. Third, teaching support facilities for the faculty are needed. Finally, an organization which takes complete charge of the instruction evaluation must be established.
