There have been so many methods described for the correction of the deviated noses but it is difficult to get satisfactory results and recurrence rate is high. There is no exact explanation why the recurrences are so high and no estabished guides for techniques according to the surgical pathology. We found the classical swinging door technique effective in cases where the caudal septum deviated from the midline. However, where the caudal septum and the tip stay in the midline, scoring or submucosal resection do not work well enough to cortet them. We used the reverse swinging door technique of our own. After elevation of mucoperichonodrium, we did sagittal section in the posterior septum and moved the septum to the midline on the pivot point of the caudal septum and. The gap created in the posterior portion of the septum were filed with bone grafts, cartilage grafts or Medopor, which were sutured to the septum, We did this technique with or without osteotmies in 56 deviated noses for last 5 years. The results were very satisfactory and there was no complication.

The short term beneficial effect of arthroscopic excision of synovial tissue in knees with rheumatoid arthritis have been well documented. The purpose of this study to report the results of synovectomy in patients with rheumatoid arthritis who have been observed at least 3 years. We analysed the clinical result with modified Laurin criteria, radiologic change and patients own satisfaction degree with survey. The results were as follows; 1. The preoperative symptoms were pain (100%), swelling (100%), decreased range of motion (83%) and joint tenderness (74%), and those were improved postoperatively to 43%, 60%, 11%, 43% each other. 2. Among the laboratory parameters, C-reactive protein (CRP) was improved most significantly (pvalue =0.026). 3. On simple supine A-P X-rays, the width of medial joint space and lateral joint space were compared to preoperatively and postoperatively. The width of medial joint space was 4.33mm preoperatively, and it was changed to 3.22mm at last follow up (p=0.032). Those of lateral joint space was changed from 4.24mm preoperatively to 3.27mm at last tollow up (p=0.106). 4. The grade of articular cartilage damage was related with severity of preoperative symptoms and the patients with low grade of articular cartilage damage showed more postoperative improvement. The result of operation was related to symptom duration, degree of X-ray change and degree of cartilage damage. 5. 58% ot patients were satisfied to results of synovectomy, 28% were answered neither satisfied nor ansatisfied and 14% were unsatisf'ied to operation. We concluded the arthroscopic synovectomy of the knee joints was effective procedure to improve the clinical symptoms, range of knee motion and to alleviate the inflammatory reaction at mid-term period al'ter the operation. So we consider this procedure is a palliative treatment that modified and alleviate the progression of rheumatoid arthritis of knee joints.

8.Co-Occurrence of Two Phylogenetic Clades of Pseudoperonospora cubensis, the Causal Agent of Downy Mildew Disease, on Oriental Pickling Melon

The genus Pseudoperonospora, an obligate biotrophic group of Oomycota, causes the most destructive foliar downy mildew disease on many economically important crops and wild plants. A previously unreported disease by Pseudoperonospora was found on oriental pickling melon (Cucumis melo var. conomon) in Korea, which is a minor crop cultivated in the temperate climate zone of East Asia, including China, Korea, and Japan. Based on molecular phylogenetic and morphological analyses, the causal agent was identified as Pseudoperonospora cubensis, and its pathogenicity has been proven. Importantly, two phylogenetic clades of P. cubensis, harboring probably two distinct species, were detected within the same plots, suggesting simultaneous coexistence of the two clades. This is the first report of P. cubensis causing downy mildew on oriental pickling melon in Korea, and the confirmation of presence of two phylogenetic clades of this pathogen in Korea. Given the high incidence of P. cubensis and high susceptibility of oriental pickling melon to this disease, phytosanitary measures, including rapid diagnosis and effective control management, are urgently required.

Clinical and histopathological studies were made on 202 cases of malignancy of cervix, that were visited to the Department of Obstetrics and Gynecology, Yeungnam University Hospital, during 5 years from 1983 to 1987. The results were summarized as follows. 1. Malignancies of the uterine cervix were 10% of total female malignancies. 2. Among 202 cases, 195 cases (96.5%) were squamous cell carcinoma, in which 60 cases (30.0%) of carcinoma in situ, 9 cases (4%) of microinvasive, and 126 cases (62.5%) of invasive carcinoma were included. 3. The average age of the patients with squamous cell carcinoma was 49.4 years old; In case of carcinoma in situ, it was 43.8, microinvasive, 40.0, invasive 52.1 years old. 4. Clinical symptoms of the patient with squamous cell carcinoma in order of frequency were as follows; vaginal bleeding (47.5%), abnormal cytology (15.4%), and abnormal vaginal discharge (9.4%). 5. Duration of the chief complaints was most commonly less than 6 months (73.2%), and the average duration was 3.8 months. 6. The most common age of marriage was between 19 to 22 years old (46.5%). The average was 21.5 years old. 7. The gravity was 51.5% in 5-8 times, and average 6.2 times. The parity was 61.9% in 1-4 times, and average 3.9 times. 8. The subdivision of 126 cases of invasive carcinoma was made according to FIGO stage classification, stage I, 40 cases (31.8%), stage II, 54 cases(42.9%), stage III, 11 cases (8.7%), and stage IV, 8 cases (6.3%). 9. The histologic subtypes of invasive squamous cell carcinoma were distributed as follows; large cell keratinizing type, 25 cases (19.8%), large cell nonkeratinizing type, 101 cases (80.2%). 10. In the cytologic diagnosis, class I was 2 cases (1.9%), class II was 16 cases (15.1%), class III was 33 cases (31.1%), class IV was 31 cases (29.3%), class V was 24 cases (24.6%). 11. The frequency of lymph node metastasis was 7.5% in stage I, and 11.1% in stage II.
