1.Axial Stiffness of the Ilizarov Frame Using the Rancho Mounting Technique.
The Journal of the Korean Orthopaedic Association 1998;33(7):1928-1932
The Ilizarov fixator allows significantly more axial motion at the fracture site than the conventional monofixators. But the transfixing wires have inevitable problems of soft tissue impalement. Therefore the Rancho mounting technique, replacing the transfixing wires with half pins, has become a common place. But the increment of the axial stiffness secondary to replacing transfixing wires with half pins has not been defined clearly yet. The authors measured the axial stiffness of the Ilizarov fixator and two different configurations of the Rancho frame. The group I frame was the Ilizarov fixator composed of four rings and two transfixing wires on each ring. The group II frame was the Rancho frame and it was constructed same as the Ilizarov frame but a transfixing wire was replaced with a half pin from two central rings respectively. The group III frame was another type of Rancho frame which was constructed same as the second group but the remaining transfixing wire was replaced with a half pin from the two central rings respectively. The axial stiffness of the Group I , II and Group III frames were 71.54+/-7.21N/mm, 89.65+/-6.42N/mm, 101.01+/-7.92N/mm respectively. The axial stiffness difference between the Group I frame and the Group II frame was statistically significant(p<0.01). Also the difference between the Group I frame and the Group III frame was statistically significant(p<0.01). This study shows that the replacement of two transfixing wires with two stainless half pins resulted in significant increment of the axial stiffness of the Ilizarov frame.

A polymerase chain reaction (PCR) method for detection of the pathogenic Yersinia pestis from other Yersinia spp. was developed. Five Y. pestis strains, ninety-two other Yersinia species and twenty-four Enterobacteriaceae strains were collected in Korea and from other countries. Oligonucleotide primers were designed from pathogenic gene of antiphagocytic protein capsule gene (fra 1) and plasminogen activator gene (pla). The 428 bp DNA fragment was amplified from five Y. pestis which contained the fra I gene. No product was amplified from other Yersinia species and other strains of the Enterobacteriaceae. The 439 bp DNA fragment was amplified from three K pestis which contained the pla gene. No product was amplified from two Y. pestis, other Yersinia species and other strains of the Enterobacteriaceae. These showed that the designed primers were specific for detection of Y. pestis among other Yersinia species and Enterobacteriaceae strains. Amplification was successful whether the template was derived from purified DNA or from aliquots of boiled bacterial suspension. The detection limits were 100 pg of DNA and 100 colony forming units (CFU) for fra I and 100 pg DNA and 10 CFU for pla, respectively. Our results prove that the PCR method using specific primers for Y. pestis is a rapid and convenient procedure for routine clinical detection and identification of Y. pestis.
