Our department established a bone bank using autolyzed, antigen extracted, allogeneic bone (AAA bone) in which the immunogenicity is markedly reduced by chemical treatment, and has started its clinical application to reconstruction of bone defects. An outline of the bone bank and the clinical results are reported. The graft used AAA bone prepared by chemically treating (e.g. decalcification using hydrochloric acid) cortical bone of human long tubular bones of the upper and lower limbs. In 1994, we first decided to transport AAA bone from the Federal Republic Germany to Japan for clinical application. We also recruited domestic donors by asking neighboring hospitals to provide excess bone fragments resected in plastic surgery of the jaw and lower limbs amputated from severely diabetic patients due to peripheral necrosis. These procedures were carried out with the approval by the Safety Measures Division, Drug Safety Bureau, Ministry of Health and Welfare and the Ethical Committee of our University. The donors were selected according to the donor qualification criteria of the Japan Orthopedic Society and with sufficient precaution against infection of Creutzfeldt-Jakob disease. Four limbs (of 4 patients) have been provided to date, prepared into AAA bone by chemical treatments at our department, and used clinically. AAA bone implantation has been made in 16 patients to date. They were 12 males and 4 females aged 15 to 65 years. Their diseases were mandibular cysts in 13, odontoma in 1, fracture of the mandible in 1, and malignant tumor of the mandible in 1. Postoperative panoramic radiograms were obtained in 6 patients with mandibular cysts 2 years or longer after surgery, and the state of bone formation at the implantation site was observed. The oral cavity was also examined for abnormalities, and the percent efficacy was calculated from the results of both examinations. The usefulness rating was very useful in 4 and useful in 3, with a percent efficacy of 100%. The results were satisfactory also in patients followed up for a shorter period after surgery. AAA bone was removed due to infection in only 1 patient, but none of the recipients developed a serious complication. The maximum followed-up period to date is 4 years and 7 months. The postoperative course has been uneventful in all patients, with none showing abnormalities. From these results, AAA bone is considered to have the following merits: (1) By sterilization with EO gas and vacuum packing after preparation, AAA bone can be preserved at room temperature, be used at any time, and is easy to handle. (2) It is highly plastic and can be readily adjusted to various forms during surgery. (3) Implanted AAA bone is completely replaced by the recipient bone. (4) The degree of bone formation at the implantation site can be easily evaluated by radiography

A Study on the User Value of the ScienceNet Blog

[Purpose/significance] The development of academic blogs is closely related to the use of users. The paper explores the user value which guides users to use academic blogs, and analyzes the relationship among user values. [Method/process] Based on Woodruff’s customer value hierarchical model, the paper conducted semi-structured interviews with 10 ScienceNet blog’ users through the laddering theory, and then encoded the interview content. [Result/conclusion] This paper creates the comprehensive correlation matrix of customer value of ScienceNet blog, and builds the user value hierarchy model. It also finds four value chains: blog writing--accomplishment, blog reading--academic communication, recommendation--communication effect, mutual friendship--academic communication

水貂病毒性肠炎病例

青海省某貂场,自1月28日,貂群中零星发生病貂（肠炎症状）,以后病貂逐步增加,至2月28日水貂死亡达158只,自2月29日至3月8日死亡108只。3月1日开始配种。由于水貂之间接触,造成疾病暴发流行。截止3月20日,死亡503只,发病率达95％,死亡率16.7％,致死率17.6％。河北省某貂场,于3月9日发现一只排灰黑色稀粪便之病貂,经抗菌素治疗未愈。3月22日出现具有肠炎症状的病貂,3月29日又发现5只病貂。截止4月2日,发病率已达54％,致死率为4.07％,而疫病仍蔓延流行。疾病的诊断 1.临床症状病貂表现热性病症状,食欲降低或废绝,精神萎糜、倦怠,四脚伸展或卷缩地趴卧。体温升高,40.5—41℃
