Characterizations of the VP4 (P type) and VP7 (G type) genes of Korean isolates of bovine rotavirus were performed using RT-PCR/RFLP and nucleotide sequencing analysis. After RT-PCR amplification of partial length (1094bp) of the VP4 and full length (1062bp) of the VP7 genes, amplified PCR products were digested with restriction endonucleases and digestion patterns were compared with those of reference rotaviruses. With the VP4 genes, four RFLP (AD) profiles were observed; three (A, B and C) were the same as those of bovine rotavirus NCDV (P[1]), IND (P[5]) and B223 (P[11]), respectively, Profile D was the same as that of porcine rotavirus OSU (p[7]). With the VP7 genes, five RFLP profiles (I-V) were observed; three of them (1, II and III) were the same as those of bovine rotavirus NCDV (G6), Cody I-801 (G8), and B223 (G10), respectively, Profile IV and V were atypical to those of reference bovine rotaviruses used in this study. These two profiles were identified as G6 and G5, respectively, after analyzing and comparing the nucleotide sequences. The G typing analysis revealed that 61.9% (26/42) were G6, which included G6 subtype; 28.6% (12/42) were G5; 7.1% (3/42) were G10; 2.4% (1/42) were G8. The P typing analysis revealed that 54.8% (23/42) were P(5); 28.6% (12/42) were P(7); 11.8% (5/42) were P(11); 4.8% (2/42) were P(1). Our results showed that G6/P(5) were the most prevalent rotaviruses in diarrheic calves in Korea. Also, this is the first report that G5P(7) rotaviruses were identified from cattle with diarrhea.

Through the review of 137 cases of ankle fracture treated and followed up in Department of Orthopedic Surgery, National Police Hospital, we got the following results. 1. Slipping was the most frequent cause of the fractures(45.3%). 2. Supination-external rotation type of Lauge-Hansen classification was more common than any other types(67.9%). 3. 94 cases out of 137 cases were treated by open reduction and internal fixation, and remaining 43 cases were treated conservatively. 4. The average duration of cast immobilization was 7.3 weeks for the operatively treated cases and 9.1 weeks for the conservatively treated cases. 5. The result of treatment was good or excellent in 87 cases(92.6%) of operatively treated 94 cases and in 36 cases(83.7%) of conservatively treated 43 cases. 6. We think that the anatomical reduction of the lateral malleolar or distal fibular fracture is necessary for better end results.

The fracture of the tibial condyle involving the articular surface can produce some disability of the knee joint because it is frequently accompanied by soft tissue injury to the ligaments and menisci. Accurate anatomical reduction and rigid internal fixation with early mobilization is known to provide good results. The authors analysed 50 cases of the fracture of the tibial condyle which were treated with recent method(anatomical reduction, rigid fixation and early joint motion) at the Dae Han Hospital from January, 1988 to May, 1993. The results were summerized as follows: 1. The associated injuries were ligamentous injury in 24 cases(48%), fibular fracture in 21 cases(42%), femur fracture in 7 cases(14%) and meniscal injury in 7 cases(14%). 2. According to Hohl's classification, the split compression type was most common in 17 cases(34%), and there were 14 comminuted type(28%), 8 local compression type(16%), 7 total condylar compression type(14%) and 4 split type(8%). 3. Method of internal fixation were plate & screw in 32 cases(64%), tibial bolt & screw in 18 cases(36%), bone graft in 31 cases(62%), ligament repair in 24 cases(48%) and menisectomy in 4 cases(8%). 4. The clinical result by Insall's criteria were excellent in 37 cases(74%), good in 8(16%), fair in 3(6%), poor in 2(4%) among 50 cases.

Colles' fracture is a common injury encountered in emergency departments. Despite the frequent experience of every orthopedic surgeon with Colles' fracture, considerable variation remains in the treatment of fracture of the distal radius. Everyone nearly agress that reduction of the fracture is not difficult, but maintenance of reduction is the problem. Eighty patients with Colles' fracture were treated with closed reduction and percutaneous pinning under the C-arm fields and followed up more than 1 year, from January 1990 to May 1993 at the Department of Orthopedic Surgery, Dae Han Hospital. The results of this study were as follows: 1. The fractures were classified according to the system of Gartland and Werley. Of the 80 cases, 12(5%) were type 1; 25(31%) type 2; and 43(54%) type 3. 2. Complications were such as; temporary neuropathy of median nerve 2 cases, redisplacement 2 cases, radiocarpal arthritis 1 cases, stiff hand 1 case and shoulder hand syndrome 1 case. 3. The overall assessment showed exellent in 29 patients(36.2%), good in 44 patients(55,0%) and poor in 7 patients(8.8%) under the subjective and objective criteria of Gartland and Werley and the objective criteia of Scheck. 4. The results were mainly correlated with maintenance of an anatomical reduction. 5. The percutaneous pinning was suitable for anatomical restoration and maintence, had less com plication and more advantage such as the early range of joint and simple technique. Conclusively, it was considered to be one of ideal method for the treatment of Colles' fracture in selected cases.

Bronchioloalveolar carcinoma may present with a variety of radiographic and clinical appearances. The authors reviewed the radiographs of 17 patients with pathologically proven bronchioloalveolar carcinoma, retrospectively. Seven cases were of the localized form. Among the seven five showed a localized mass and two showed localized consolidation. Ten cases were of the diffuse form. Among the ten, three showed diffuse nodules, two showed diffuse consolidation, and five showed a combined pattern of nodules and consolidations. Progression of disease was observed in 9 patients. In these cases, localized forms progressed to a diffuse forms and nodular patterns progressed to a consolidation pattern. Seven cases of the diffuse form were given antituberculous medications on hospital admission. In summary, bronchioloalveolar carcinoma has varied radiographic patterns, and often mimicks other pulmonary diseases such as pulmonary tuberculosis.

PURPOSE: The loss of estrogen and progesterone receptors appeats to be associated with a progression to less differentiated and hormone-independent tumors. The gain of hormone independency over time even in estrogen receptor-positive tumors has become another obstacle to endocrine therapy for breast cancer. We tried to regain the hormone dependency in estrogen receptor-negative breast cancer cells by lipofecting estmgen receptor cDNA. MATERIALS AND METHODS: The mutant human estrogen receptor cDNA (pSGS-HEO) was lipofected into estrogen receptor-negative human breast cancer cell line MDA-MB-231, in an attempt to restore their sensitivity to antiestrogen. Then the effects of 17p-estradiol and tamoxifen were studied by counting viable cell numbers after treating the lipofected cell line with either one or together. RESULTS: Culture medium cantaining phenol red, a weak estrogen, has growth advantages compared with culture medium without it. In both culture conditions, cell growth was most profoundly inhibited in 4 days after lipofection with mutant human estrogen receptor cDNA, which was overcome after that day. Tamoxifen, as an antiestrogen, showed a growth inhibitory effect slightly stronger tban combined conditions of tamoxifen and 17- estradiol compared to estrogen-treated group and to control, and the inhibitory effect was lasted 4 days. CONCLUSION: The temporary induction of estrogen receptor by lipofection with pSGS-HEO on estrogen receptor-negative human breast cancer cell line MDA-MB-231 showed negative growth control on these cells by tamoxifen, indicating that liposome-mediated estrogen receptor transfection may be used as a novel therapeutic strategy for hormane independent human breast cancers in the near future.
