Primary oxalosis is a rare genetic disorder caused by a deficiency of the peroxisomal enzyme alanine-glyoxylate aminotransferase(type I) and D-glyceric dehydrogenase(type II). It is characterized by the triad of radiopaque urolithiasis, nephrocalcinosis, and latered renal function. We report a case of primary oxalosis in a 10-year-old Korean girl. She presented with chronic renal failure at 9 years of age. Ultrasonographic examination revealed bilateral, multiple renal and ureteral stones. Removed stones were chemically analysed to be composed of calcium oxalate. She underwent renal transplantation after prolonged period of dialysis. Removed kidneys were firm and gritty. Cut sections showed numerous tiny yellow sandy stones and a large staghorn stone. Specimen X-ray also exhibited disseminated fine granular and often coalescent radiopaque materials throughout the cortex and medulla. Microscopically numerous varying-sized crystals were noted in the kidney in globular or rhomboid appearance. The crystals were semitranslucent and doubly refractile under the polarized light. Diffuse interstitial fibrosis and chronic inflammation as well as glomerular obsolescence were also noted. The oxalate deposit was diffuse and marked, and was thought to be intimately related to the parenchymal damage and fibrosis.

In order to investigate the mechanism of antibacterial effect of electrical stimulation on bone and joint infection, 5, 50 and 500 µA constant currents were passed through the silver electrodes and stainless electrodes on the Brain Heart Infusion agar culture plates which contained Staphylococcus aureus, Pseudomonas aeruginosa, and Lscherichia coli. After 24 hours of incubation, the widths of inhibitory zone around the electrodes were measured. The broth dilution susceptibility test was also used to verify the antibacterial effects of electrically generated silver in the Brain Heart Infusion broth. The results were as follows. 1. Silver anodes using constant currents manifested antibacterial effects definitely on the three bacterias, but stainless anodes showed none. 2. Antibacterial effects of silver anodes on the three bacterias increased in proportion to current density. However, antibacterial effects were negligible when current density was under 2 nA/mm2. 3. When current density was between 6.6 and 660 nA/mm2, there were no statistically significant differences in the antibacterial effects among 5, 50 and 500µA constant currents. 4. The culture broth containing silver ions generated by constant current electrolysis also manifested antibacterial effects. The retentate showed stronger antibacterial effects than the filtrate. Form these results, following conclusions were drawh. 1. The antibacterial eff ct of silver electrode using constant current was due to silver ions rather than electricity itself. 2. The substance which showed most effective antibactericity effects was silver complex larger than 2,000 m.w. and heat-unstable.

The bipolar hemiarthroplasty is one of the treatment methods of the avascular necrosis of the femoral head and the fracture of the femur neck. The mechanism of bipolar hemiarthroplasty is intended to distribute the forces at the site of the inner and outer articulation, and theoritically diminish acetabular wear and produce a painless arthroplasty. The authors analyzed motion of two components in 23 cases of the bipolar hemiarthroplasty, performed at the Department of Orthopaedic Surgery, Korea University Hospital, between January, 1985 and January, 1993 with average 47 months follow up(range 24 to 84 months). The results obtained were as follows: 1. In the motion of the two components, inner bearing motion was average 11.5 degrees(from 1 to 29 degrees) and outer bearing motion was average 21.4 degrees(from 3 to 45 degrees). 2. The inner bearing motion was highest at 12 months with average 16 degrees and outer bearing motion was lowest during the same period with average 15 degrees. During the follow up the inner bearing motion was decreased whereas outer bearing motion was increased. 3. The inner or outer bearing motion of bipolar component was no correlation with age, sex and clinical result.
