The transference of patterns printed or indented on a sheet of paper to a plastic surface

Experiments have been made in which the image of Xerox-letters printed on a sheet of paper is transferred to a sheet of plastic and developed by dusting. The sheet of paper is sandwiched between two sheets of plastic, which are pressed between two flat metal plates by a mechanical press. After removing the pressure, the sheet of plastic facing the letter-printed surface of the sheet of paper is separated or torn from the paper using electrically insulated forceps. Then by sifting fine alumina powder onto the plastic surface, a dust figure can be obtained. This figure shows the transcribed letters corresponding to the original Xerox-letter on the sheet of paper.By this method, indented letters, or letters drawn with ink on a sheet of paper, or a fingerprint impressed on a sheet of paper can be transcribed onto the surface of a sheet of plastic.     

Time-course changes in the expression of heme oxygenase-1 in human subcutaneous hemorrhage

To determine the time-course of human subcutaneous hemorrhage, heme oxygenase (HO)-1 expression and macrophage infiltration were observed using an immunohistochemical technique and semiquantitative analysis. The number of immunoreactive cells and the number of all infiltrating cells of each microscopic field were counted, and the ratio of the former to the latter was calculated as the positive cells ratio. An increase in the HO-1-positive cells ratio was observed starting at 3 h after injury, and the maximum ratio was observed 3 days after injury. The pattern of the increase in the macrophage ratio was similar to that of the HO-1-positive cells ratio in the early period after injury. Observation of serial sections revealed that the expression of HO-1 in the cells corresponded to the localization of macrophage. The present results suggest that the determination of HO-1 expression, as derived from macrophages, might be useful for the estimation of the time-course of subcutaneous hemorrhage.     

与开发有关的犯罪及预防犯罪的新局面——对未来的挑战

<正> 一、前言第7届联合国预防犯罪会议的第1个议题是:《与开发有关的犯罪及预防犯罪的新局面——对未来的挑战》。1982年5月联合国经济社会理事会确认本议题时,即将其列为这届会议的主要议题。它是全部议题的主导议题,因此,本议题则成为这次会议从始至终全体会议讨论的一个议题。第1周(8月26日至30日)通过了《米兰行动计划》为首的与第1个议题
