Clinical analysis was done on 60 meniscus injuries operated on at Orthopaedic Department of Capital Armed Forces General Hospital from Mar. 1977 to Sept. 1978 with the following results. 1. All cases were military personel aged from 21 to 40, most of them 23 and 24 years old. 2. The fall down accident was the most common cause of injury mechanism. 3. The lateral meniscus was more frequently injured than the medial with 43:17, and the right side knee than left with a ratio of 35:25. 4. The posterior horn tear was the most common type of the injuries involved 23 cases (48.3%). 5. The complete healing after menisectomy ranged from 1 month to about 3 months. 6. It seems resonably certain that habit of exaggerated flexion of the knee in Korean is an important factor in the production of the lesion, combined possibly with medial ratation of the tibia, for subsequent episodes of the exaggerated flexion enlarge the rent untill the popliteus attachment and all peripheral attachments behind the hiatus are torn away, and the posterior half of the lateral meniscus is released from normal control.

A 72-year-old woman with a pea sized, bluish, firm nodule was diagnosed as having a cellular type of dermatofibroma histopathologically. A biopsy specimen revealed a relatively well circumscribed, non-encapsulated, nodular infiltration of irregularly distributed histiocytes in the deep dermis. Foam cells were also noted. Gomoris iron stain revealed large amounts of hemosiderin deposits and some collagen were present as individual fibers in the lesion with Masson's trichrome stain.

Filiform polyposis(FP), an unusual form of inflammatory polyposis, has been recently designated to a lesion characterized by multiple, long slender, finger-like projections of mucosa and submucosa of the gastrointestinal tract. We present 5 cases of FP, of which two were associated with irritable bowel syndrome, two with advanced colon carcinoma, and one with active ileotyphlitis(Behcet's disease). The polyps ranged from 1.0 cm to 3 cm; they were either isolated or aggregated, and their numbers were up to 100. The common microscopic feature was filiform polyps which consisted of central submucosal core covered by intact or minimally inflamed intestinal mucosa, comparable with that in reparative processes and formation of inflammatory(redundant) pseudopolyps. We conclude that awareness of FP in non-inflammatory bowel disease may promote the endoscopists to search its underlying disease and prevent unnecessary surgical procedure. Behcets enterocolitis in the ileocecal junction seems an additional preceding disorder of a localized form of FP.

Pathological proliferation of Brgnners gland is rare, and its wide range of morphologieal variations have led to confusing the terminology with considerable lack of agreement. Six cases of duodenal nodular lesions which consisted of pathological proliferation of Brunners glands were examined by light microscopy. Polypectomy was made in two cases, and the remaining 4 cases were examined with endoscopic biopsy materials. Two polypectomy specimens, 2 cm and 3 cm each in great diameters, consisted of protruded ovoid mass with broad and short stalks. Microacopically, all of 6 cases revealed thin strands of fibrous connective tissue which separated the normal-looking Brunners glands in lobules. Individual lobules were composed of groups of acini formed by cuboidal cells admixed with occasional endocrine cells. Presence of glandular and ductal configuration of the Brunners gland aside from thick, randomly arranged bundles of smooth muscle were featured without distinct relation to interlobular septa. Also, one polypectomy case disclosed the nests of fat cells interspersed with the glandular acini. One mucosal biopsy case contained not only the smooth muscle bands but also the intimate mixture of both acini and ducts. We conclude that some of heterogeneous composition of duodenal nodular proliferation of Brunners gland is indicative of a hamartomatous growth.

The fracture of acrylic resin dentures remains an unsolved problem. Therefore, many investigations have been performed and various approaches to strengthening acrylic resin, for example, the reinforcement of heat-cured PMMA resin using glass fibers, have been suggested over the years. The aim of the present study was to investigate the effect of short glass fibers treated with silane coupling agent on the transverse strength of heat-polymerized PMMA denture base resin. To avoid fiber bunching and achieve even fiber distribution, glass fiber bundles were mixed with PMMA powder in conventional mixer whose blade was modified to be blunt. Composite of glass fiber (11micrometer diameter, 3mm & 6mm length, silane treated) and PMMA resin was made. Transverse strength and Young's modulus were estimated. Glass fibers were incorporated with 1%, 3%, 6% and 9% by weight. Plasticity and workability of dough was evaluated. Fracture surface of specimens was investigated by SEM. The results of this study were as follows 1. 6% and 9% incorporation of 3mm glass fibers in the PMMA resin enhanced the transverse strength of the test specimens (p<0.05). 2. 6% incorporation of 6mm glass fibers in the PMMA resin increased transverse strength, but 9% incorporation of it decreased transverse strength (p<0.05). 3. When more than 3% of 3mm glass fibers and more than 6% of 6mm glass fibers were incorporated. Young's modulus increased significantly (p<0.05). 4. Workability decreased gradually as the percentage of the fibers increased. 5. Workability decreased gradually as the length of the fibers increased. 6. In SEM and LM, there was no bunching of fibers and no shortening of fibers.
