The orchid symbiotic fungi were isolated from the roots of Korean native orchid (Cymbidium goeringii) collected and Chinese orchid (C. sinense) obtained from greenhouses. They were identified as a species of Rhizoctonia, based on the sequences of 18r rDNA, the microscopic observations of mycelia, and the symbiotic relationships with commercial orchids. The isolate collected from Chinese orchids was revealed to be a species of Ceratobasidium endophytica, and to be different from the other isolates at the thickness of the mycelia stained in the root cells of Korean native orchids. The other isolates collected from the Korean native orchids were considered to be a species of Tulsanella repens (anamorphic: Epulorhiza repens) or its related one. The physiologic or microscopic variations were oftenly observed among them, but the tendency of grouping these in the 18s rDNA sequences were observed to be consistent with those of the localities collected. The further taxonomical segregating for Korean symbiotic fungi was not made because the information concerned were limited in this moment, but was recognized as based on the sequences of 18s DNA.

Fracture of the shaft of the humerus had been treated by many different way, such as hanging cast, shoulder spica cast, abduction splint, and Velpeau bandage, etc, The authors have employed the new trianglar splint designed by ourselves for the 54 cases of fracture of the humeral shaft from Jan., 1965 to Oct., 1976 in the department of Orthopedic surgery of Han-il Hospital. In our experience, the triangular splint method is useful for not only fracture between the head of the humerus and supracondylar region, but also shoulder joint injuries and diseases which need firm immobilization. The triangular splint method has merits, such as spontaneous reduction by the fractured arm weight with gravity, the stability during care, relatively comfort during procedure. Satisfactory results had been obtained by the triangular splint method.

Arthroscopy has now become a valuable method for the diagnosis and treatment of the internal derangement of the knee. Based on the experiences gained during the past three years, in which 93 knees with posttraumatic disorders were observed arthroscopically, several uncommon and interesting findings were encountered. Such illustrative findings have been summarized here. I. Injury at the parameniscal portion is readily overlooked and especially the middle and posterior one-thirds are inaccessible. A wavy undulation of the concave margin of the meniscus, when abnormally exaggera;ed by tibial rotation, possibly suggests the presence of this type of injury. 2. The discoid cartilage and the bucket-handle tear of meniscus occasionally show similar pattern arthroscopically. 3. The plica of the knee can sometimes be a cause of knee disorders. Any internal derangement, which tends to be localized around the patella, warrants close scrutiny for its presence. 4. A large foreign body within a knee joint could easily be removed by virtue of direct arthroscopic visualization.

Monostotic Fibrous dysplasia is a relatively rare condition. Three such conditions are experienced at the Dept. of Orthopedic Surgery, Han-II Hospital during the period of September 1970 to June 1972. Two of three cases were involing shaft of left and right tibia respectively, one of which was complicated by pathologic fracture. The third case was on greater trochanter of right femur. All of three cases were treated with curertage and bone graft. Excllent results were obtained.

One hundred patients of osmidrosis were treated by surgical procedure at the Department of Dermatology, Wonkwang University Hospital. The methods of operative treatment were elliptical excision for 37(74), bipedicle incision with apocrine glancl undercutting for 14(28), and single incision wit.h apocrine gland undercutt,ing for 49 (98). The results were summarized as follows : 1. Of the 74 axillae treated by elliptical excision, one occurred recurrence, and 1.7 showed complication, hematoma in 6, infection and delayed union in 4, each necrosis and severe scar in one each, 2. Of the 28 axillae treated by bipedicle incision with apocrine gland undercutting, 6 showed complication; hematoma in 4, infection and delayed union in one each 3. Of t..he 98 axillae treated by single incision with apocrine gland undercutting, 5 showed complication, hematoma in 3, infection and delayed union in one each In conclusion, single incision with apocrine gland undercutting was found to be more excellent compared with the other surgical methods.

All-ceramic restorations have become an attractive alternative to porcelain-fused-to-metal crowns. In-Ceram, and more recently IPS Empress 2 were introduced as a new all-ceramic system for single crowns and 3-unit fixed partial dentures. But their strength and marginal fit are still an important issue. This study evaluated the fracture resistance and marginal fit of three systems of 3 unit all-ceramic bridge fabricated on prepared maxillary anterior resin teeth in vitro. The 3 all-ceramic bridge systems were: (1) a glass-infiltrated, sintered alumina system (In-Ceram) fabricated conventionally, (2) the same system with copy-milled alumina cores (copy-milled In-Ceram), (3) a heat pressed, lithium disilicate reinforced glass-ceramic system (IPS Empress 2). Ten bridges of each system with standardized design of framework were fabricated. All specimens of each system were compressed at 55degree at the palatal surface of pontic until catastrophic fracture occurred. Another seven bridges of each system were fabricated with standard method. All of the bridge-die complexes were embedded in epoxy resin and sectioned buccolingually and mesiodistally. The absolute marginal discrepancy was measured with stereomicroscope at x50 power. The following results were obtained: 1. There was no significant difference in the fracture strength among the 3 systems studied. 2. The Weibull modulus of copy-milled In-Ceram was higher than that of In-Ceram and IPS Empress 2 bridges. 3. Copy-milled In-Ceram (112micrometer) exhibited significantly greater marginal discrepancy than In-Ceram (97micrometer), and IPS Empress 2 (94micrometer at P=0.05. 4. The lingual surfaces of the ceramic crowns showed smaller marginal discrepancies than mesial and distal points. There was no significant difference between teeth (incisor, canine) at P=0.05. 5. All-ceramic bridges of three systems appeared to exhibit sufficient initial strength and acceptable marginal fit values to allow clinical application.
