Sporulation of Bacillus subtilis is induced by the deprivation of the nutrients in the medium. During sporulation more than 50 sporulation qenes (spo) are expressed sequentially. The sequential expression of spo genes is regulated mainly at the level of transcription, which is governed by the cascades of five sporulation-specific sigma factors, σ^H, σ^F, σ^E, σ^G, and σ^K. At the initiation of sporulation, the first sporulation specific sigma factor σ^H is activated, which then activates spoIIA operon encoding the second sigma factor σ^F. Expression of spoIIA and spoIIE operons is required for the activation of the pro-σ^E, the inactive precursor of the third sigma factor σ^E, which is required for the expression of the fourth sigma factor σ^G. σ^G is present only in the forespore, but its function is required for the activation of the pro-σ^K, which is present only in the mother cell. sigK gene encoding σ^K is construted by the mother cell-specific DNA rearrangement occurring during the middle stage of sporuation.

Since 1984, we have performed osteosynthesis for intertrochanteric fracture of the femur using CHS method.79 Compression Hip Screws and 12 Captured Hip Screws were used for 46 stable and 45 unstable intertrochanteric fractures of the femur.The mean age was 77.9, ranging from 61 to 96 years.Among 91 patients, 8 patients could not walk even before the injury. 62 patients out of the remaining 83 patients (74.7%) were discharged with one cane gait.The major symptoms of 62 patients who could walk postoperatively were knee pain (25.8%) and thigh pain (9.7%).The major radiographic findings of those 62 patients were shortening of the neck more than 5mm (25.8%). But the shortening of the neck and the knee pain don't seem to correlate to each other.21 patients out of 83 patients (25.3%) were not able to walk on one cane. But systemic complications seemed to be the main causes in more than half of those 21 patients.
