The purpose of this study is to examine the effect of “sacrifice bunt” in baseball, executed when a runner is on first base with no outs. The offensive strategies studied are, “sacrifice bunt”, “base stealing”, “hit-and-run”, “hitting”, and “hitting after first attempting to bunt”. We recorded 846 official games of Japanese Professional Baseball in 2006, and selected 3994 cases to categorize the strategies and the results. The results are as follows:     (1) Following the bunts, the runner on first moved up to second base 81.6% of the time, but the base runner advanced only 40.7% after hitting.     (2) However, following the bunts,the runner on first reached home plate 37.6% of the time. This probability is almost the same as the one after hitting.     (3) The expected number of runs in one inning for each strategy was: 0.73 for bunting, 0.86 for hitting, and 0.95 for the “hit-and-run”.     There are possibilities that the effectiveness of five strategies are not the same as the result of (1) to (3), not in case of a league format and higher skill level. In this study, we didn’t discuss about each case with various situations, but examined many cases (3994) comprehensively. Based on our results we can see that it isn’t advisable to choose the “sacrifice bunt” in this situation. It seems that a more effective strategy for scoring runs is either hitting or executing the “hit-and-run”.

足関節より近位での切断を大切断といい, 重症下肢虚血 (critical limb ischemia : CLI) の治療において, 救命や除痛, 再建不能などの理由で救肢ができず, 大切断を余儀なくされることがある。しかし, 病状によってはその大切断でさえ安全ではない。私たちは当科で大切断を目的に血行再建術を施行した 5 例について検討した。その結果, 全例再手術することなく創治癒していた。また 4 年以上の経過観察期間において死亡例は 1 例であり, いわゆる重症下肢虚血における大切断後の予後よりもよかった。大切断が必要な症例においても切断部位の血流精査を行い, 切断に耐えられる血行再建術を施行することは, 生命予後の改善においても有用であると思われた。
