牛凍結胚の子宮角への移植部位が受胎に及ぼす影響を調べた. 1.5Mエチレングリコール (EG), 1.5M EG+0.1Mスクロース (Suc) を用いて凍結した胚は, 融解後に凍害保護物質を除去せずに直接移植し, 1.4Mグリセリン (Gly) を用いて凍結した胚はGlyを除去した後に移植した. その結果, 子宮角基部 (子宮角分岐部より2～4cmの部位) と子宮角中央部 (子宮角分岐部より10～15cmの部位) に移植した時の受胎率は, それぞれ68.7, 69.2および67.4%と31.7, 68.8および70.5%であった. 1.5MEG+0.1M Sucおよび1.4MGlyを用いて凍結した胚では移植部位による受胎率に差が認められなかったが, 1.5MEGを用いて凍結した胚では子宮角基部に移植した時に受胎率が高かった (P<0.01).

How should we save our personal memories? Many people keep diaries and take
pictures for that purpose. In this study, we kept things of personal significance in a
time capsule for 9 years and examined whether personal memories could be saved in
a time capsule and how they might possibly change over time. We held a workshop
in 2003 when participants put something that they had possessed which had personal
significance at that time of their life. They were interviewed to explain what kinds of
significance these possessions had for them, and these interview sessions were recorded.
Nine years after the initial workshop, the participants came together again. Before the
time capsule was opened, they were asked to recall what they had put in the time capsule
and to describe in what ways their possession in the time capsule had been significant
to them. By comparing the contents of the participants’ responses between 2003 and
2012, it was found that a great deal of the contents have been changed from 2003 to
2012. Implications were discussed as regards to the significance of objects themselves
and the narratives that go with the objects in preserving personal memories.
