An 18-month-old male Alaskan malamute was euthanized due to slowly growing mass around the left femur after history of left posterior limb lameness. At necropsy, a firm confluent mass approximately 15cm in diameter was noted surrounding the femur and proximal portion of the tibia/ulna with traumatic ulceration of the overlying skin. On cross sections of the mass, many unencapsulated firm tan coalescing lobules were noted. The neoplasm consisted of closely packed spindle cells with homogenous eosinophilic material (osteoids) between the neoplastic cells. The pulmonary metastasis was confirmed. Based on the gross and histopathologic examinations, the case was diagnosed as juvenile osteosarcoma.

A 6 month-old male Labrador retriever was presented for intermittent lameness on the left forelimb after exercise. The dog was suffering progressive lameness that had started two months before. On mediolateral radiographic view of the left elbow, proximal margin of the anconeal process was irregular. A lucent, indistinct line separating the anconeal process from the ulna was observed, when the elbow joint was flexed. The lateral approach to the elbow joint was used and the ununited anconeal process was removed. The limb was bandaged after surgery for 7 days to support soft tissue and exercises were restricted. The dog showed normal limb function 3 weeks after surgery. On a telephone conversation with the owner 18 months after surgery, the dog was reported to maintain normal function of the limb.

Seasonal occurrences and dynamics on the freshwater algae were examined in the upstream of the Yongsan river system with the Kwangju service water area from 1993 to 1994. Three hundred and three taxi were totally collected and composed of 6 classes, 15 orders, 7 suborders, 31 families, 74 genera, 248 species, 48 varieties and 7 forma. Compositions in each algal class were divided in 136 taxi of Chlorophyceae(44.8% ), 109 taxi of Bacillariophyceae(36.0% ), 30 taxa of Cyanophyceae(10.1% ), 21 taxa of Euglenophyceae(6. 9% ),4 taxi of Chrysophyceae(1.3% ) and 3 taxa of Dinophyceae(1.0% ). The occurrence of taxa was a markedly decrease(-62) between summer and autumn, the critically increase(+43) between spring and summer. And also, it was indicated that the high frequency of taxa in summer, but the high standing biomass In winter in spite of low taxi. In general, it has much algal biomass in station 9 and 10, but low in station 4, 5 and 11, relatively. Through this survey, the major dominant taxa in algal biomass, Microcystis aeruginosa, Melosira varians, Synedra ulna and Navicula cryptocephala, they were all above 2.1×10$^{6}$ce11s/1, 13.2% of totals. There are about 10% of new emigrated taxa by season and they showed a remarkable succession. We may suggested that this system was well sustained for the habitat of freshwater algal community with low dominance and high diversity. Twenty three of nuisance algae including of Microcystis aeruginosa, Peridinium willei and Anabaena flos-aquae were distributed as if had low appearance. Of course, many of them were saprobiontic taxa, extraordinary growttung groups depend on organic loading in water system and also it was not showed severe algal blooming phenomenon.

Patterns of epilithic algal colonization on artificial substrata (unglazed ceramic tiles) were investigated from 23rd April to 3rd July 1999 at weekly intervals over a 10 weeks period outside and inside the mesocosm in Togyo reservoir within the Civilian Passage Restriction Line near Demilitarized Zone (DMZ) in Korea. The highest standing crops of epilithic algae was 1,798$\cdot$10³ cells$\cdot$$cm^{-2}$ outside the mesocosm on 26th June and also inside the mesocosm those was 2,391$\cdot$10³ cells$\cdot$$cm^{-2}$ on 26th June, 9 weeks after the experiment began. The dominants outside the mesocosm were Achnanthes minutissima, Navicula bicephala, Oscillatoria angusta, Synedra delicastissima, S. tenuissima, S. ulna v. danica and Tabellaria flocculosa, and those inside the mesocosm were Achnanthes minitissima, Coenochloris polycocca, Fragilaria crotonenesis, Peridinium cinctum, Synedra delicatissima, Tabellaria flocculosa and Ulothrix subtilissima. Diatoms were most abundant and Achnanthes minutissima was the most important species colonizing on the tiles. Chlorophyll-a content was highest value of 5.4 mg$\cdot$$m^{-2}$ on 19th June after 8 weeks growth outside the mesocosm and was 24.4 mg$\cdot$$m^{-2}$ on 26th June, 9 weeks after the experiment began on tiles inside the mesocosm. It was also shown that unglazed ceramic tiles were a more suitable substratum for colonization than the glass slides. Consequently the substratum selection plays an important role in the colonization by the epilithic algal community.

Purpose: Rupture of a collateral ligament of the metacarpophalangeal joint is rare except in the thumb. The injured digit became flexed and deviated toward ulna side by the hypothenar intrinsic musculature. Incomplete rupture of a collateral ligament of the metacarpophalangeal joint can be often managed by splinting the affected digit in flexion position, however, in the case of complete tears that distraction of the ends of the ruptured collateral ligament is too great to allow repositioning by splinting. Primary repair of the ruptured collateral ligament or reattachment to bone by a pull-out wire, or tendon graft technique appears to be adequate. Methods: We report a case of instability of fifth metacarpophalangeal joint due to complete rupture of radial collateral ligament. This 18-year-old male presented pain in his right outstretched hand after trauma. The diagnosis was obtained by physical examination and simple radiography. Because of persistent instability after the initial conservative treatment, open reduction and repair surgical treatment was required. Results: The fifth metacarpophalangeal joint became free of pain and stable under forced lateral deviation. Postoperative results showed good metacarpophalangeal joint function and stability during 8 months follow-up period. Conclusion: Because of the interposition of the sagittal band between the ruptured ends of radial collateral ligament such as Stener-like lesion of the thumb, surgical repair of metacarpophalangeal joint collateral ligament of the finger was justified in case of complete laxity in full flexion.

발음성 삼두근 증후군은 주관절을 굴곡하거나 신전할 때 삼두근 말단부 일부와 척골 신경이 내상과 전방으로 탈구되는 드문 질환이다. 이학적 검사 만으로는 다른 질환으로 오진되는 경우가 많아 정확한 진단이 필수적이며 확진을 위하여는 척골 신경 및 삼두근의 비정상적인 움직임을 관찰할 수 있는 영상 검사가 필요하다. 초음파 검사는 자기 공명 영상 촬영 등 다른 검사에 비해 간편하고 효과적으로 연부 조직의 동적 검사를 시행할 수 있는 장점이 있다. 저자들은 발음성 삼두근 증후군 환자를 동적 초음파 검사를 사용하여 진단하고 척골 신경 전방 전위술 및 삼두근 내두의 이전술을 시행하여 치유하였기에 문헌 고찰과 함께 초음파 검사의 유용성을 보고하고자 한다.

We analyzed 11 children who underwent epiphyseal transplantation to the forearm for manage growing deformity ranged from 2 years 6 months to years(average 5 years 10 months) follow-up period. Etiologies of the functional impairment of the eleven were five traumatic, three congenital and three tumorous conditions. Lesions of epiphysis were distal radius in eight patients and distal ulna in three patients. Operation was performed with removal of non-functioning or deformed epiphysis followed by transplantation of free vascularized proximal fibular epiphysis with microvascular anastomesis. Evaluation was performed radiologically and functionally. The 9(81.8%) patients showed growth of transplanted epiphysis by radiological examination during follow up. At the last follow up, average growth rate was 0.86cm per year excepts 2 cases of no growth. Active wrist motion near normal to contralateral joint was achieved in 7 patients. In other 2 patients, active joint motion was improved but weaker than contralateral joint. Complications on donor site were two transient peroneal nerve palsy which have been resolved after 2 and 5 months post operation and one valgus ankle deformity. The ankle deformity was corrected with $Langenski\"{o}ld$ operation of the dital tibiofibular fusion. At recipient site, there was one superficial infection and it was easily controlled by systemic antibiotics. Many subsequent reports have described successful nonvascularized epiphyseal transplante, but overall results have been inconsistent and unsatisfactory. Other experimental and clinical studies in the transfer of vascularized epiphyses has encourage its clinical application. We also could gel successful growth in several cases with free vascularized epiphyseal transplantation.

The purpose of this report Is to discribe the radiological findings of traumatic elbow luxation and subluxation of carpal joint which were caused by being hit by a wild animal and forced hyperextension of carpus in two hunting dogs. In case 1, carniocaudal and mediolateral radiographic examination of the elbow joint revealed that the radius that the radius and ulna were completely luxated laterally. The lateral projection showed the humeral condyles overlying the radial head with an absent joint space, but displacement is apparent on the craniocaudal projection. Incidence of collateral ligament rupture in conjunction with elbow luxation was not recognized on physical examination of the limb after closed reduction. Radiographic examination of the elbow made 5 months after closed reduction revealed only mild degenerative joint disease. Radiographic examination of the carpus in case 2 demonstrated palmar subluxation of most carpal joints including antebrachiocarpal, mediocarpal carpometacarpal joints, and some intercarpal joints, and avulsion fracture of the palmar surface of the accessory carpal bone. However, the mediocarpal and carpometacarpal joints were most severely affected by tensile forces of hyperextension, and it was concluded that the ligaments of the middle ca,pal joints and carpometacarpal joints as well as the palmar fibrocartilage were ruptured based on clinical and radiographic findings. In elbow luxation and subluxation of carpal Joints of the dog, differentiation of the joint or joints involved, and ligamentous structures damaged is important in determining whether surgery Is necessary and which procedure is most appropriate. And the radiographic findings of these conditions would be of help to practitioners.
