An isolated granulocytic sarcoma (chloroma) of the left ovary occured in the absence of leukemia in a 12-year-old woman. This lesion is defined as a localized tumor mass composed of immature cells of the granulocytic series. Granulocytic sarcomas can occur at extramedullary sites including ovary but, isolated myelosarcoma in the absence of usual manifestations of AML may be rare and has some difficulties in diagnosis. Contrary to findings in other series, granulocytic sarcoma arising in this nonleukemic patient did not progress to acute leukemia during two years she has been followed.

Chronic complication of diving and working in compressed air is dysbaric osteonecrosis. Dysbaric osteonecrosis could be diagnosed by simple bone x-ray, in the case of exposure history to dysbaric atmosphere. The case is 44 years old man who worked as a shell fish diver for 20 years. He was exposed dysbaric atmosphere during diving. He had bone necrosis in both femur head, both distal femur and proximal tibia. He had multiple attacks of decompression sickness. Other causes of bone necrosis are ruled out. We conclude that diver's bone necrosis is dysbaric osteonecrosis.

The serum level of immunoglobulin E (IgE) in 28 atopic patients and 41 healthy, normal, non-allergic subjects were measured by standard radial immunodiffusion method (RIDT). The correlation between IgE level and clinical manifestations are studied. The results are as follows. 1) IgE value was higher in atopic dermatitis than normal subjects. 2) IgE value in atopie dermatitis revealed no sigaificant difference between in male and in female. 3) IgE value was increased parallel with the severity of the disease. 4) IgE value was not correlated with the extent of disease. 5) IgE value was not correlated with the duration of disease. 6) IgE value was not correlated with the age of onset. 7) IgE value was not correlated with the eosinophil count of peripheral blood.

Melanoma is relatvely uncommon malignant tumor arising in the skin from epidermal melanocytes, from the junctional component of a cellular nevus or, rarely within a blue nevus and frequently metastasizes to regional lymph nodes first, followed by hematogenous spread to lungs, liver, gastrointestinal tract, pancreas, adrenal, heart and brain. All melanoma patients are carefully evaluated according to several parameters. A complete history and physical examination are carried out, with particular attention being devoted to other pigmented tumors that the patient may have. The patient should be further evaluated to determine the presence or absence of metastases by chest X-ray examination, metastatic series or bone scan, liver function studies, liver scan, EKG, etc. Special factors such as age, sex, and race, as well as site, size, and growth rate of lesions are also evaluated. We had a case of 59 year-old male patient with disseminated malignant melanoma. Upon his first visit, we did not find any abnormality in his physical examination and routine laboratory findings except skin tumors on left heel and left leg.

Endoscopic ACL reconstruction using bone-patellar tendon-bone has been considered the gold standard in the field of reconstructive ACL surgery. Technically, graft must be placed at isometric point. But it is difficult to evaluate the placement of graft postoperatively. The purpose of this study is to determine the radiological ideal position of graft by comparing postoperative results with the graft placement. Seventy cases of endoscopic ACL reconstruction were reviewed and classified according to the femoral and tibial graft position on radiologic imaging. The femoral graft position was classified in relation to angle of graft on anterior position view and distance from posterior margin of graft to the inner surface of posterior cortex on lateral view. The tibial graft position was classified in relation to intercondylar eminence on anterior posterior view and lateral view. Knee score (modified Marshall, Lysholum), manual anterior instability test (Lachman test, Pivot shift test) and arthrometer measurement were checked to evaluate postoperative results in each case. The results of this study implicate that knee joint in which femoral graft was oriented at direction of 11 o clock centring around 68 degree respect to tibial joint and placed within 3mm from posterior cortex showed higher knee score and lesser laxity. In cases of tibial side, the graft oriented to intercondylar eminence (AP view) and placed anterior to intercondylar eminence (lateral view) showed higher knee score and lesser laxity.

A black scab disease occurred on sword bean (Canavalia gladiata) in plastic film houses around Chinju area during the spring season of 1999. The disease started from flower bud, then moved to flower stalk, pod, petiole, cirrus, stem and leaves. The lesions started with small dark brown spots then were gradually expanded. Severely infected plants reached 37.4% of whole plant covered with scab. Numerous conidia were produced on the diseased flower disk, pod, floral axis, stem and leaves. Most of the conidia were appeared to be readily dispersed in the air, but the mycelia were not suggested causing of sooty mold by ectoparasitism. A fungus was isolated from the diseased stem, and inoculated to healthy plants to satisfy the Koch's postulates and proved the fungus was the causal agent of the disease. The isolated fungus grew on potato dextrose agar, forming greenish black to pale brown colonies. Conidia were ellipsoidal, fusiform or subspherical, mostly one-celled but occasionally septated. The conidia were 3.9~34.1x2.7~5.1microm in size and formed in long branched chains on the erected conidiophores which were pale olivaceous brown and variable in length between 7.2~210.7microm in size. Ramoconidia were 7.6~29.2x3.2~14.4microm in size. The fungus was identified as Cladosporium cucumerinum based on the above morphological characteristics. The optimum temperature for mycelial growth and conidial formation was about 15 to 25degrees C. Cladosporium scab of sword bean caused by the fungi has not been reported in Korea previously.

A soft rot of fruits caused by Rhizopus nigricans occurred on peach (Prunus persica var. vulgaris ) in The Chinju City Agricultural Products Wholesale Marke during in summer season of 2000. The disease infection usually started from wounding after harvest fruits, and then moved to outside. At first, the lesions started with water soaked and rapidly softened and diseased area gradually expanded. In severely infected film house, the rate of infected fruits reached 65.2%. Numerous sporangiospores were produced on the diseased fruits. Most of the sporangiospores were appeared to be readily dispersed in the air. The mycelia grew surface of fruits and produced stolons. Colonies on potato dextrose agar at 25~30degrees C white cottony at first becoming heavily speckled by the presence of sporangia and the browinish black at maturity, spreading rapidly by means of stolons fired at various points to the substrate by rhizoids. Sporangia were 85.3~243.5x53.4~219.2microm in size and were globose or sub-globose with. somewhat flattened base. The color of sporangia was white at first and then turned black with many spores, and never over-hanging. Sporangiophores were 8.9~36.6microm in width, smooth-walled, non-septate, light brown, simple, long, arising in groups of 3~5 from stolons opposite rhizoids. Sporangiospores was 9.7~24.8x5.9~15.8microm, irregular, round, oval, elongate, angular, and browinish-black streaked. Columella was 70.2x149.7microm. brownish gray, and umberella-shaped when dehisced. The causal organism was identified as. Rhizopus nigricans Lind on the basis of the morphiogical characteristics of the fungus. Rhizopus soft rot on peach (Prunus persica ) caused by the fungi has not been reported in Korea. This is the first report of rhizopus soft rot on peach caused by Rhizopus nigricans in Korea.

Rhabdomyosarcoma which was first described by Weber has generally been considered asan uncommon tumor. Pack and Eberhart were of the opinion that rhabdomyosarcoma represented 13.9 percent of soft tissue sarcomata. Recently it was classified as four types such as pleomorphic, embryonal, botryoid and alveolar type by many authors. We have experienced two cases of embryonal rhabdomyosarcoma, one arised within left leg and the other within right foot. The former(3 months old, female) showed tumor mass at birth, the latter(13 months old, male) showed at 1 month after birth.

We developed an animal model to recreate the condition of an open fracture in communication with the maxillary sinus. We then studied wound healing of the sinus wall structures following fracture in the presence of autogenous bone and alloplastic implant. This model is designed to simulate the repair of an orbital floor fracture in humans. The New Zealand White rabbit was used as the animal model. Standardized 8mm defects were made bilaterally in the maxillary sinuses to include bone and mucosa in 36 rabbits. Two different implants and autogenous calvarial bone graft were placed in the soft-tissue pockets to obturate the defects, exposing one surface of the implant to the open sinus. Medpor porous polyethylene, silicone and calvarial bone implant were compared. Animals were killed at 1, 2 and 8 weeks after implantation. Gross examination of the specimens for the amount of mucosal closure and implant tissue fixation was performed. Histological sections were evaluated for bone and soft-tissue morphology juxtaposed to the implant. Complete closure of the mucosal defect was demonstrated with each type of implant. Medpor implants showed both vascular and soft-tissue ingrowth into pores by week 1. Bone ingrowth was seen by week 2. Closure of the Medpor obturated defects occurred more rapidly than in the silicone group. The Medpor implants and calvarial bone demonstrated bone and soft-tissue fixation, callus formation and maturation, while mature overlying mucosa was reconstituted over the defects. Silicone implants demonstrated a fibrous tissue reaction within 1 week of implantation and they never became fixed to bone or soft tissue. Maxillary sinus wall regeneration occurred in all defects. This study supports clinical observations of maxillary sinus wall regeneration in humans.

A black scab was observed on strawberry(Fragaria ananassa) in plastic film houses around Jinju area during the winter of 2000. The disease started from leaves then moved to calyx and runner. At the beginning, the infected area started with small dark brown spots then gradually expanded. The pathogenic fungus was purely isolated from the diseased leaves, calyx and runner. The fungus was inoculated to test Koch's postulates and proved to be the causal agent of the disease. The isolated fungus grew readily on potato dextrose agar, forming dark green to dark gray colonies. The optimum temperature for mycelial growth was about 25degrees C. The diameter of growing hyphae was 3.8~5.6 microm. Conidia were ellipsoidal, ovoid or subspherical, mostly one-celled but occasionally septate. The size of conidia were 4.1~11.7x3.8~5.3 1-cell, 9.3~18.8x4.0~7.4 microm 2-cell and formed in long branched chains on the erected conidiophores which were dark brown and variable in length between 28.8~236.2x3.0~6.2 microm in size. The fungus was identified as Cladosporium herbarum on the basis of its morphological characteristics. The black scab disease of strawberry caused by C. herbarum has not been reported in Korea previously.
