The study was undertaken to evaluate the protective effect of epinephrine on renal radiation injury. For theexperiment, 50 rabbits were divided into 3 groups; the first group of 9 rabbits were used to determine theavailable dosage of epinephrine as preliminary study, the second group of 18 rabbits were used to evaluate theradiation injury as radiation group, which were received a single dose of 2,000 rads of radiation on unilateralkidney using 60 Co teletherapy unit, and the third group of 23 rabbits were used to assess the radioprotective effedct of epinephrine as radiation

Results of 170 total knee arthroplasties(TKAs) performed from 1986 to 1995, followed up for at least one year, were reviewed. Lateral retinacular release was performed in 76 knees(45%) and not performed in 94 knees(55%). We compared the results of TKAs combined with lateral retinacular release with those without lateral retinacular release. The clinical results of TKAs were evaluated by the Knee Scoring System of Hospital for Special Surgery(HSS). The average follow-up period was 34 months. The clinical results assessed by HSS score, pain score and range of motion improved postoperatively in both groups, but there was no significant difference between the two groups. There were 8(4.7%) with patellar subluxations in 170 TKAs, one(1.3%) in the group with lateral retinacular release and 7(7.5%) in the group without lateral retinacular release(t-test; p<0.05). Analysis of lateral tilt of patella on roentgenographs also showed a significant difference between the two groups. 7 knees(9.2%) with lateral tilt were observed in the group with lateral retinacular release and 22 knees(23.4%) with lateral tilt in the group without lateral retinacular release(t-test; p<0.05). There was no osteonecrosis or fracture of patella in either group. In summary, lateral retinacular release might improve the patellar tracking and lower the incidence of patellar subluxation and lateral tilt of patella. Lateral retinacular release alone did not seem to cause patellar osteonecrosis and subsequent patellar fracture which were detectable in plain roentgenographs. So, we suggest that lateral retinacular release can be performed without great risk of potential patellar complications in TKAs requiring lateral retinacular release for proper patellar tracking.

From Jan. of 1990 to Dec. of 1992, we have experienced three cases of multiple primary malignant neoplasms originated from different histogenesis, in the Department of Orthopedic Surgery of Korea Cancer Center Hospital. Liposarcomas, malignant fibrous histiocytoma were combined with renal cell carcinoma, mucinous cystadenocarcinoma of ovary or prostatic cancer. With Moertel's classification, synchronous tumors were found in 2 cases and metachronous in 1 case. Synchronous tumors were 2 liposarcomas-renal cell carcinoma or mucinous cystadenocarcinoma of ovary. Metachronous tumors were malignant fibrous histiocytoma-prostate cancer. We couldn t find any family history among them. The causes of these multiple malignancies were considered as the individual predilrection to tumors.

Authors reviewed 21 cases of unstable intra-articular fractures of the distal radius treated with open reduction and internal fixation to improve anatomical and functional results during March 1990 to May 1993 at Dong-A University Hospital. The following results were obtained; 1. The most common injury type was type VIII(9 cases) according to Frykman's classification, type C,(8 cases) according to AO classification, and open fractures were 4 cases. 2. Twelve cases were treated with open reduction and internal fixation with external fixator and 9 cases were treated with open reduction and internal fixation with cast. 3. According to demerit point rating system, excellent to good results were obtaned in 76.2%. In cases of external fixator application, excellent and good results were 88.3%, compared to 66.7% in cases of cast application. 4. In last follow-up examination, the mean loss of radial length was 0.9mm(10.0%) in cases of cast, but 0.3mm(3.3%) in cases of external fixator, the mean loss of radial inclination was 2.7° (16.7%) and 1.8° (11.0%) respectively, the mean loss of volar tilt was 2.9° (19.6%) and 2.4° (16.4%) respectively, and there were statistical significances in all three parameters between the external fixator group and the cast group(p < 0.05). 5. Open reduction and internal fixation, combined with external fixation was thought to be a better method than open reduction and internal fixation with cast for the treatment of unstable comminuted fractures of the distal radius, because that was more comfortable and convenient to patients and useful to prevent late displacement or collapse of fractures.

While there is little controversy about the surgical resection for the torn discoid lateral meniscus, there are some contradictory reports for the treatment of discoid lateral meniscus without tear. Some authors argue that initial treatment should be observation after diagnostic arthroscopy in the cases without tear. Others reported that excellent results were obtained after partial resection of the discoid lateral meniscus without tear or with slight degeneration. We reviewed our series of symptomatic discoid lateral menisci without tear, confirmed by arthroscopic examination. We retrospectively reviewed 8 knees in 8 patients who had had partia! Meniscectomy for discoid latera1 meniscus without tear, confirmed by arthroscopic examination. They were 5 males and 3 females. The average age was 22.8 years (range, 7 to 57 years). The average duration of follow-up was 2 years and three months. The patients had continuing pain and locking or snapping preoperatively. Preoperative MRI had grade Il intrameniscal signal in all the cases. The patients were evaluated hy Lysholm pain score and total Lysholm score. There were 7 complete types and one incomplete type. The average Lysholm pain score and the total Lysholm score improved from 13.1, 67.8 preoperatively to 28.8. 97.9, at the last follow-up, respectively. Mechanical symptoms including click and 1ocking were disappeared in all, and no complication was obser ved. We suggest that symptomatic discoid lateral meniscus should he resected e.ven though there is no tear visible on arthroscopy, especially when the MRl shows grade lI intrameniscal signal.

A preparation of water soluble components(EA) was made from carpophores of Elfvingia applanata(Pers.) Karst and its in vitro antibacterial activity on a number of bacterial species was examined by macrobroth dilution assay. Among 16 species of bacteria tested, the most potent antibacterial activity was observed against Staphylococcus epiderrnidis and Proteus vulgaris, of which MICs were 1.25 mg/ml. To investigate the antibacterial effects in combinations of EA with quinolone antibiotics, such as ciprofloxacin, enoxacin, lomefloxacin, norfloxacin, and ofloxacin, the fractional inhibitory concentrations(FICs) and the fractional inhibitory concentration indices(FICIs) for four bacterial strains were determined by macrobroth dilution checkerboard assay. Combinations of EA and quinolones exhibited either additive or indifferent effects of antibacterial activity in most instances. However, both synergistic and antagonistic effects were not observed in any cases.
