〔報告〕日光の歴史的建造物で採取した虫糞調査：シバンムシ科甲虫各種間の虫糞形状比較

Since life period of adult Anobiidae is short in general,it is difficult to find live adults during visual survey on site. However,holes and insect feces can sometimes give information of activity and probable species. Feces of major wood-boring insects were collected in the large-scale survey of historic buildings in Nikko conducted in 2010. Five species of Anobiidae were found in the survey: Priobium cylindricum, Trichodesma japonicum, Sculptotheca hilleri, Hadrobregmus pertinax and Oligomerus japonicus. Insect feces of 4 of these species were collected from damaged wood and observed. It was found that feces of Priobium cylindricum and those of Hadrobregmus pertinax are similar and they appear powdery to the naked eye but a closer look reveals them to be irregular in shape. Feces of Trichodesma japonicum are very similar to feces of Nicobium hirtum, but generally bigger in size. Feces of Sculptotheca hilleri also appear powdery to the naked eye, and when they were observed under a microscope it was found that many were globular shaped. As feces of Sculptotheca hilleri have characteristic shape and size when compared with those of other species of Anobiidae,it is likely to identify them from feces alone. Information other than those of feces, such as the sizes of holes and distribution of insects, need to be taken into consideration when making more precise identification although insect feces can provide good clues for insect identification

Serum beta 2-microglobulin in spinal cord injury patients--its efficacy as a screening test of renal function

We evaluated the reliability of serum beta 2-microglobulin (beta 2-MG) in comparison with serum creatinine, blood urea nitrogen and creatinine clearance in 164 patients with spinal cord injury. The value of serum beta 2-MG demonstrated the highest correlation coefficient (r = -0.927) in relation to creatinine clearance. The beta 2-MG value reflected the severity of hydronephrosis on excretory urography, with very few false negative values. The value of beta 2-MG is concluded to be one of the best screening tests in evaluating renal function in spinal cord injury patients

Comparison of life and psychological status of the elderly between families with children absent and families with children

目的　比较研究城市空巢老人与非空巢老人的生活和心理状况。方法　以《中脉老年生活质量指数调查问卷》为材料,对7个城市2 225位独居、夫妻同住和非空巢老人的调查数据进行分析。结果　大多数老年人的经济收入偏低,非空巢老人给予子女经济支持和体力付出的压力较大;大多数老年人的心情较好,但超过1 /4的独居老人心情较差;老年人的主观幸福感居中上水平,但独居老人的主观幸福感、与家人交流满意度较低;在养老依靠问题上空巢老人(尤其是独居老人)对于家人的期望较低;对于第三方赡养和老年人再婚的问题,夫妻同住老人比较理解和支持。 结论　夫妻同住老人的生活和心理状况均较好,独居老人的心理状况较差,非空巢老人的经济和体力付出的压力较大
