The Enchondroma is a benign cartilage forming harmartoma arising chiefly from short tubular bones on hands and feet. If on a long tubular bone or flat bone such as femur or ilium, it is most likely to be a true neoplasm such as chondrosarcoma, not a harmartoma. A case of enchondroma was reported. It occurred over right ischium of 19 years old male and was found incidentally by roentgenogram. The lesion was biopsied and diagnos's was confirmed by histologic examination. It was treated by curretage with filling of cavity with bone chips. Post operative-course was uneventful.

Korean Journal of Pathology 1985;19(3):255-289
This study was carried out to investigate the morphological changes in the exocrine and endocrine glands of rat pancreas treated with endotoxin. Thirty-five male Sprague-Dawley rats, maintained on a stock diet, weight 200.0 gm. average. were divided into two experimental groups. Group 1. Control group. Five rats. Intraperitoneal infections of 0.3 ml normal saline only. Group 2. Endotoxin-treated group. Thirty rats. 7.6 mg of endotoxin per kg. of body weight was administered intraperitoneally. Each of 5 experimental animal was sacrificed 30 minutes, 1, 2, 4, 6 and 8 hours after endotoxin treatment, followed by examinations of histochemical, light and electron microscopy of both transmission and scanning modes. The results were as follows: A. Light microscopic findings: A mild interstitial edema and hyperemia were noted 1-hour after endotoxin treatment. Cytoplasmic vacuolization at 2-hour level(2-hours after endotoxin administration), diminished staining quality of both endocrine and exocrine cells at 6-hour level. B. Electron microscopic examination: a. Transmission electron microscopy. The acinar cells of pancreas showed a mildly increased pre-lysosome at 30-minute level. At 1-hour level, appearance of secondary lysosome was noted in addition to the findings of mitochondrial swelling and decreased cristae; disarray and vacuolization of the RER; vacuolar change of Golgi apparatus. At 6-hour level, post-lysosomes. The changes in the endocrine glands were similar to the findings of exocrine glands just described with time lag of 1 to 2 hours. The endothelial cells of capillaries show swelling and pinocytotic vesicle formation, protrusion of the cytoplasmic processes into the capillary lumen and increased heterochromatin at 1-hour level. These findings became more prominent as time lapses. The lumen of the endothelium tends to be narrowed, filled with fibrin and other blood cell components which later terminated with occasional complete occlusion by the formation of thrombi. b. Histochemical study: Primary lysosomes of the control group revealed a strong reaction of the acid phosphatase whereas the endotoxin treated group with less reactivity limited in the peripheral zones of the lysosomes. Secondary lysosomes with partial reactions. However, the pre-lysosomes and post-lysosomes failed to demonstrate any acid phosphatase activity at all. c. Scanning electron microscopy. The endothelial cells of the capillaries, arterioles and venules demonstrated increased microvillous activity, broad bled formation, cytoplasmic protrusion into the luminal spaces and microthrombi formation at 1-hour level. Six-hour level onward there noted a junctional disruption and partial detachment from the subendothelium of the wall. It can be concluded, therefore: When the endotoxin enters the blood stream, it elicits endothelial injury followed by both exudation with resultant edema of the surrounding tissue and concomitant vascular occlusions due to thrombosis. This vascular occlusion, in turn, causes ischemic degenerative change of the cells of exocrine and endocrine glands of the pancreas which are followed by digestions of degradational materials from the injured cells through the lysosomal phagocytic system. Besides the above pathogenetic pathway, one can not rule out the possibility of the direct effects of the endotoxin to the cells of exocrine and endocrine cells of the pancreas also so rendered.

An giant cell tumor arising from the tendon sheath and other soft tissue of the extremities, hasbeen of clinical and pathologic interst for many years, which is the second most common tumor of the hand, but it is not common in other location. One case of tendon sheath giant cell tumor with regional bone destruction on the pharangeal bone is presented which experienced at Department of Orthopaedic Surgery, Korea University recently. At first, the lesion of bone that is confused with Enchondroma in roentgenographically, which is confirned regional bone destruction of tendon sheath giant cell tumor by histologically. The tumor is composed of a vascularized network of spindle shaped or ovoid stromal cell regularly and rather interspersed with multinuclear cell and xanthoma cells. We report a case of giant cell tumor of tendon sheath and review of literature.

The head-pelvic skeletal traction was first attempted in 1958 by Arther R. Hodgson., and was described. The Halo skull traction apparatus by Perry and Nickel (1959), the method were provided for immobilising the unstable cervical spine, correction of the Scoliotic deformity, Tuberculotic Kyphosis, and other deformed disease. We performed Halo-pelvic apparatus,after posterior-fusion of unstable cervical spine, on a 24 year old male, with Quadriplesia due to Fracture-dislocation of the 7th cervical spine in May 1976. The following were the condition to be met: 1) Rigid stabilization and improved the cervical pain. 2) progressive adjustable., longitudinal traction for reduction 3) The patient was able to sitting position withont other Supports. 4) No pressure sores developed as happens beneath a cast. 5) Ease of patient management and taking of Roentogenogram.

The fibrous dysplasia, divided into 3 categories of the monostotic, polyostotic and extraskeletal forms, is a relatively rare disease which was first reported by Well in 1922 and shows a characteristic findings replacing the medullary cavity of noe or more bones by the pathologically proliferating fibrous connective tissues. In a consequence, the structural integrity of the diseased bone becomes weakened and suffers frequent episodes of pathologic fracture and deformities of the bone, which are most common around the hip. Various operative methods and instruments have been tried to manage the pathologic fracture around the hip recently. The authors report a satisfactory resnlt of total hip replacement for the pathologic fracture in a patient of the fibrous dysplasia involving the proximal half of the right femur.

This study was carried out to investigate the mechanisms of acinar cell deletion, leading to the pancreatic atrophy of rat pancreas after experimental duct ligation. Fifty-seven male Sprague-Dawley rats, maintained on a stock diet, weighing 200 gm, in average, were divided into 2 experimental groups. Group 1. Control group. Six rats. Abdominal cavity was opened and closed without further treatment. Group 2. Fifty-one rats. Animals were treated with partial ligation of the pancratic ducts according to the procedure developed by Hultquist followed by sequential sacrifices at: 1 hour (3 rats), 3 hours (3 rats), 6 hours (6 rast), 12 hours (3 rats) and 24 hours (8 rats); 2 days (8 rats), 3 days (3 rats), 4 days (3 rats) and 5 days (5 rats); 1 week (3 rats), 2 weeks (3 rats) and 8 weeks (3 rats); after partial ligation was extirpated and examined by both light and electron microscopy. The results obtained were as follows: Light microscopically, noted were an interstitial edema and focal necrosis of the pancreatic tissue along with fine vacuolization and depletion of the zymogen granules in the acinar cell cytoplasms and condensation of the acinar cell nucleus. These changes were observed by 2 days after ligation. At about the same time, one can observe the dense body, identified to be apoptotic body, in the acinar cell which were found to be decreased in quantity. By 5 days after ligation, no recognizable acinar cells left in the collagenous stroma except intercalated ducts. Conspicuous stroma except intercalated ducts. Conspicuous stromal hyalinization, thereafter. Electron microscopically (TEM and SEM), nuclear condensation and margination toward the nuclear membrane was noted by 6 hours after duct ligation. By 24 hors sporadic membrane-bounded apoptotic bodies appeared in the acinar cells, the number of which reaching to the peak by 3 days after ligation. These apoptotic bodies were found to be phagocytosed by either intraepithelial mononuclear phagocytes or adjoining acinar cells. It can be concluded, therefore: That orderly remodeling of pancreatic exocrine tissue during atrophy is effected by rapid deletion of acinar cells by apoptosis.

The reservoir hosts of Thelazia callipaeda were examined. The eyes of the 76 dogs raised at farm, 78 military dogs (shepherds), 96 cattle, and 105 pigs were investigated for the presence of eyeworm. Among them, six worms of T. callipaeda were collected from two dogs raised at farm (2.7%), and 188 worms from 26 shepherds (33.5%). No worms were recovered from the cattle or pigs. These results suggest that the dogs, especially the military dogs are serving as a reservoir host of T. callipaeda. in Korea.
