The capability of higher ascomyceteous fungi to cause typical soft-rot decay for wood under laboratory conditions is reviewed and discussed. Fungi tested were extremely active in the decomposition of timbers. Scanning electron micrographs illustrated typical soft-rot decay pattern of higher wood decay ascomycetes, with the exception of H. trugodes that caused white-rot decay. Most of the fungi tested could be grouped as soft-rot fungi that showed typical soft-rot type II. Hypha confined primarily to the resin canals in softwoods or vessel elements in hardwoods and spread tracheid to tracheid via pits of cell wall to cell wall with mechanical force.

The genus Hypoxylon is a member of the Xylariaceae which has brown to dark brown and pha- seoliform single cell ascospores with a conspicuous full germ slit. The isolates of Hypoxylon collected from England, Hong Kong and Korea are compared with similar taxa and described. These isolations under Hypoxylon section are detailed and illustrated, using light microscopy and scanning electron microscopy. Hypoxylon howeianum and H. rubiginosum are described and compared with former collection from Korea. A key to the species is also included.

The section of Annulata under genus Hypoxylon is a member of the Xylariaceae which has ascomata with ostioles papillate ill a flattened disc. The isolates of Hypoxylon collected from the Tropic to the Temperate are compared with similar taxa and described. These isolations under Annulata section are illustrated with a light microscopy and a scanning electron microscopy. Hypoxylon archeri is newly recorded from Korea. A key to the species is also included.

Human epithelial cell line immortalized by Ad12-SV40 hybrid virus was transfected with plasmid containing HPV-16 via calcium-phosphate method. Subsequently, 8 clonal cell lines were obtained after G418 selection. Among these clonal cells, clonal cell-4(C-4) and clonal cell-6(G-6) showed increases of tumorigenic cellular properties such as saturation density, soft agar colony formation and cell aggregation. Morphological alteration such as appearane of foci was observed on these two clones after passage 6 and 7(50 to 55 days after transfection). When clonal cells and control cells were treated with MNNG(0.01ug/ml), both C-4 and C-6 showed increases of tumorigenic cellular properties and the level of increase was much more elevated as compared to clonal cells prior to MNNG treatment. Appearance of foci formation was observed in C-4 and C-6 after passage-6. After passage-8, control cells and all clonal cells showed morphological alterations. It seems that treatment of cells containing HPV-16 DNA with MNNG increases tumorigenic properties of the cells and expedite morphological transformations. (continue)

Aging changes on the upper third of the face include brow ptosis, glabellar furrowing and forehead transverse wrinkle caused by an imbalance of the forehead muscles. Surgical methods to correct these phenomena include forehead lift with a coronal incision, endoscopic access, and direct forehead skin excision. In response to a common need for cosmetic improvement in the brow-upper eyelid and a desire for minimal incisions for forehead rejuvenation, an approach through blepharoplasty incision had been developed. This approach has many advantages, such as fewer skin incision, less tissue mobilization and direct excision of the hyperactive depressor muscles. However, this approach is not suitable for those who have significant forehead wrinkle and ptosis. We used a combined subperiosteal approach for forehead lift and transection of the hyperactive corrugator and procerus muscles through blepharoplasty incision. This combined surgical technique is simple and effective to correct aging of the upper third of the face without the usual complication. We performed 10 cases of the transpalpebral approach for the correction of the upper third of the face from January 1997 to September 1998, following them up for from 3 to 6 months and obtained satisfactory results. We report our experiences with a review of the literature.

With rapid advancement in techniques of correcting multiple facial anomalies, surgical planning has become more sophisticated, and knowledge of the exact relationship between various areas of the head and face is now indispensible. The importance of capturing the face in proportions has been emphasized by many surgeons. The neoclassical canons are known to modern plastic surgeons, but their usage in surgical planning has been limited to the role of working guides. They are useful, however, in serving as standards. The authors measured 800 normal young Korean females, ranged from 19 to 26 in age, and 21 beauty contestants in Korea, ranged from 20 to 27 in age. Seven vertical and seven horizontal linear measurements were taken from each subject by one examiner. These measurements of normal face and attractive face are compared with each other, and followed by comparison with neoclassical canons. Attractive face of Korean female comprises shorter lower face, especially from stomion to menton, narrower bigonial distance, and longer midface than normal face. It also has wide palpebral fissure and narrow intercanthal distance. Korean female face comprises shorter and narrower lower face than neoclassical canons. We think that it is valuable to take into consideration of this modern concept of beauty when making a preoperative plan for facial plastic surgery.

A case of multiple myeloma combined with stomach cancer and related literatures were reviewed. A 67 year-old male patient entered the hospital with dysphagia and weight loss for 3 months. Peripheral blood examination revealed anemia with rouleaux formation. Total protein of the serum was 9.9 g/dl with hyperglobulinemia (albumin 2.7 g/dl, globulin 7.2 g/dl, A/G ratio 0.375). On the electrophoresis and immunoelectrophoresis of the serum, the abnormal protein with the pattern of monoclonal gammopathy (IgG-K type) was shown. There were multiple variable sized osteolytic lesions on skull X-ray and abnormal hot uptakes of rips on bone scan and result of rib biopsy was plasmacytoma. Gastrofiberscopy was performed to search for the cause of upper gastrointestinal bleeding, revealed stomach cancer, and the result of the gastric mucosal biopsy proved to be well-differentiated adenocarcinoma.
