Spherule and arthrospore cellular preparations were sonic-treated and separated into their respective supernatant and sediment components. Complement-fixation tests with antispherule and antiarthrospore pooled rabbit sera revealed that the soluble antigens exhibited more serological activity than the sediment preparations. After autoclaving, an arthrospore cellular antigen exhibited increased a...

The use of polyvinylpyrrolidone, an inert polymer resembling plasma proteins in its colligative effects, in the testing of micrococcaceae for sensitivity to methicillin and cephradine is described. Generally results are quite comparable with those of conventional methods. The absence of any inhibitory effect of the polymer compared to sodium chloride, and its physiological inertia compared to s...

Traumatic bone defects in the diaphyso-metaphyseal distal part of the femur are difficult to treat. Only two publications have described traumatic extrusion of a femoral shaft fragment and its successful replacement after autoclave sterilisation. We report the case of a 17-year-old patient who had traumatic extrusion of an 11- cm segment of his distal femur. The bone segment was retrieved on th...
