Ketotifen, a benzocycloheptathiophene, has an orally effective antiallergic as well as antihistaminic properties. In pervious studies, Ketotifen has shown encouraging results on patient with allergic rhinitis, either perennial or seasonal. 39 patients with allergic rhinitis had been treated with Ketotifen 1 mg twice daily for 8 weeks. And we obtained following results. 1) The efficacy rate in sneezing attack was 73.5%, in nasal discharge 71%, in nasal obstruction 58%. 2) Some improvements in at least one of three-major symptoms were noted within 1 week in 30.7%, within 2 weeks in 55.8%, within 3 weeks in 66.7%, within 8 weeks in 87.2%. 3) Physical findings such as colour, swelling of turbinate, character of rhinorrhea were not improved significantly. 4) Side effect was observed only in one patient with abdominal pain and diarrhea, which was subsided after interruption of administration. These results suggested that Ketotifen was effective in treatment of allergic rhinitis.

The N-terminal sequence of HIV1 gp41 (amino acid residues 584-623) was known to be the immundominant region of HIV1 gp41 protein. In order to determine epitope for gp41 protein of Korean anti-HIV1 positive sera, multiple antigenic peptides (MAPs) for the sequences corresponding to 584-604, 590-612, 604-623 and 584-618 of HIV1 gp41 were synthesized by solid phase method using Fmoc-Lys (Fmoc)-OH and used as coating antigens for ELISA. The reactivities of the synthetic peptides with Korean HIV1 positive (21 samples) and anti-HIV1 negative sera (22 samples) obtained from healthy blood doner were estimated by an indirect ELISA. MAPs for 584-604, 590-612 and 604-623 of gp41 reacted with 62 %, 100 % and 81 % of Korean anti-HIV1 positive sera tested, respectively. The results suggest that the epitope for HIV1 gp 41 for Korean anti-HIV1 positive sera is located in the region of amino acid 590-612 of gp41. MAP for gp41 (584-618) reacted with all (100 %) of anti-HIV1 positive sera tested, but did not react with anti-HlV1 negative sera. In addition, this MAP reacted stronger with seven samples of anti-HIV1 positive sera of anti-HIV1/2 combo performance panel than the mixture of 584-604, 590-612 and 604-623 of gp41, but did not react with anti-HIV negative serum. The high sensitivity and selectivity of MAP of gp41 (584-618) suggest that this peptide as a coating antigen in an ELISA system will be useful for antibody detection of HIV1.

A clinical observation was made on 12 children who showed severe hydroureteronephrosis on urography and long term follow up was performed after each etiologic reconstructive surgery. There were U. P. J. stricture(6 cases) and V-U reflux (6 cases) We observed the progressive improvement of renal function in spite of irreversible change on urography as a result of dismembered pyeloplasty (Anderson-Hynes) in U. P. J. stricture and vesicoureteroplasty (Politano Leadbetter) in V-U reflux. We thought that the consideration of reconstructive surgery than only nephrectomy for the correction of hydronephrosis in children was desirable, though there was irreversible change of the renal parenchyme on urography, because we found mostly the difference of degree of renal parenchymal destruction between the operative finding and the radiologic study.

25 Patients were received major spinal surgeries at main operating theater of Kangnam General Hospital from May 1990 to December 1990 by using the Haemonetics cell saver which was employed as an intraoperative blood salvage and autologous blood transfuser. The products of washed red blood cells were an average of 1490 cc packed RBC per case. Under the Light Microscopy, Washed RBC disclosed the morphologies of normal RBC size and shape. Fragmented RBCs or cell debris were not found and in one case agglutinated and denaturated RBCs were seen. While 20 patients were received spinal surgery prior to the utilization of cell saver, an average of 7.85 units of banked whole blood was transfused compared with 5.55 units in the cases of using the cell saver (p<0.05). Homologous banked blood utilization during spinal surgery declined more than 30% with the use of the cell saver. There was no evidence of infection, renal and/or hepatic failure related to the use of the cell saver. Haemonetics cell saver appeared to be safe, efficient and more over in some instanes life saving.

In recent years, digital technology has been developed in dentistry, which denture frameworks can be manufactured using DMLS (Direct Metal Laser Sintering) technique. A traditional impression method can be replaced by oral scanning and wax pattern production process can be achieved by the use of CAD/CAM techniques. The designed STL files can be sent to DMLS devices to fabricate final components of removable partial dentures (RPD). The advantages of digital dentistry are concision and precision. In this case study, a fracture of occlusal rests providing support and indirect retention was repaired by DMLS and laser welding techniques. It shows satisfactory results in adaptation accuracy and functional properties of the repaired denture.

BACKGROUND: The aim of this study was to evaluate causes of unstable total knee arthroplasty and results of revision surgery. METHODS: We retrospectively reviewed 24 knees that underwent a revision arthroplasty for unstable total knee arthroplasty. The average follow-up period was 33.8 months. We classified the instability and analyzed the treatment results according to its cause. Stress radiographs, postoperative component position, and joint level were measured. Clinical outcomes were assessed using the Hospital for Special Surgery (HSS) score and range of motion. RESULTS: Causes of instability included coronal instability with posteromedial polyethylene wear and lateral laxity in 13 knees, coronal instability with posteromedial polyethylene wear in 6 knees and coronal and sagittal instability in 3 knees including post breakage in 1 knee, global instability in 1 knee and flexion instability in 1 knee. Mean preoperative/postoperative varus and valgus angles were 5.8degrees/3.2degrees (p = 0.713) and 22.5degrees/5.6degrees (p = 0.032). Mean postoperative alpha, beta, gamma, delta angle were 5.34degrees, 89.65degrees, 2.74degrees, 6.77degrees. Mean changes of joint levels were from 14.1 mm to 13.6 mm from fibular head (p = 0.82). The mean HSS score improved from 53.4 to 89.2 (p = 0.04). The average range of motion was changed from 123degrees to 122degrees (p = 0.82). CONCLUSIONS: Revision total knee arthroplasty with or without a more constrained prosthesis will be a definite solution for an unstable total knee arthroplasty. The solution according to cause is very important and seems to be helpful to avoid unnecessary over-constrained implant selection in revision surgery for total knee instability.
