今日の日本において病気そのものの民族誌を描き出すことを目的とするならば、遅かれ早かれ、科学の現場にたどり着くことになるだろう。本論文では、種々の民族誌的ならびに科学的な材料をもとに、医学の二つの現場である臨床と研究所で行われるさまざまな実践を描く試みを展開し、そこで生活習慣と倹約遺伝子という、糖尿病学のそれぞれ異なる標的を行き来する代謝の動きを追いかけていく。糖尿病などの慢性病を患っている多くの人々は、自覚されていない体内の働きを抱きつつ、日々の生活に不可欠な知識を習得していくなかで、さまざまな他者との距離をはかる人格を再構成していく。この二つの配置を互いに見いだすプロセスをここで「代謝を生きる」と呼び、生活と生物との相互包含関係に注目したい。まずは、働き盛りの中年男性の生活世界と血糖の検査値という一見異次元のようにみえるものの間を揺れ動く「生活習慣」の動的な性格を示す。そしてこの「生活習慣」が、生そのものを意味する倹約遺伝子の関与を得て、日本人という主体と創薬の対象の間を行き来することについては、論文の後半で述べる。最後に、こうした糖尿病研究の現場で増殖しているハイブリッドを通じて、人間と非人間の多様性が互いに関係しあい、影響しあうことに着目し、人間と科学の複雑で動的な相互干渉に取り組む人類学の可能性を実験的に模索する。

<p>In the past decade and a half, anthropology, along with other human sciences, seems at last to have opened up its once-rigid theoretical frameworks and methodological toolkits to embrace the concept of life-not as something that divides social and natural phenomena, but rather as something that highlights how they relate to and include each other in practice. Interestingly enough, this relatively new concept of life has been emerging from research activities that follow the movement of living objects: genes between laboratories and regulatory agencies, mushrooms between distant mountains and global markets, and organs between living bodies, to mention just a few. In such moves, life becomes a target of and a ground for comparison. Lives and life forms are constantly compared (metrically, culturally and experientially), calling for further research that explores the relation between comparative practices and the traveling objects of medicine and the life sciences in general. This paper explores the consequences of such mobility by drawing on current ideas of translation and hybridity within science and technology studies (STS) and anthropology. How does the body of the diabetic patient-from (thrifty) genes to fat bellies-become an experimental site of technological and social innovation in contemporary Japan? What is at stake when those bodies move across different locations and scales in the comparative practices of epidemiology and genetic research? These are the questions I pursue through two ethnographic vignettes of diabetes research, which together show the fluidity between different values and different ways of ordering reality. Few diseases have pervaded the landscape of Japanese health care in the past half century as thoroughly as diabetes. It has transformed from an obscure and acute condition to one of the paradigmatic issues of biomedicine, involving the interaction between state-of-the-art science and public health intervention on a massive scale. Different facts and experiences that structure the knowledge about diabetes emerge within particular interferences between scientific and cultural attributions. Some repertoires invoke "Japanese genes," while others inscribe a stereotypical male diabetes patient: the sarariman, or company employee. The puzzle is this: how do these different subjects of molecular biology and epidemiology come to stand for the same disease, if they do at all? It will be argued that such interaction is made possible through the constant work of the metabolism. Taking a diabetes clinic as its point of departure, this paper explores the mediation between such ontological variations. In Chapter 2, I look at two ways in which high blood sugar is included in biomedical research: the recruitment of company employees in clinical studies, and the attempt of building a national database for diabetes using glycated hemoglobin as an indicator of population differences. Epidemiology, as I show, does not simply reflect popular ideas about ethnic and national identities, but is a domain in which such identities are actively articulated and reworked. In Chapter 3, I extend my analysis by following such ethnic differences to a site of genetic research. The collaborative research project I describe here is founded on the classification of populations that emerge from epidemiology. Here, however, ethnic difference signifies genetic variations and their possible consequences for developing newer and safer medications for Japanese people. The emphasis on the interfering effects of differentiation in medicine is grounded in and reflects the importance of metabolic activities in diabetes research that, in turn, leads me to rethink the anthropological significance of motion in Chapter 4. In diabetes research, the body is objectified as a metabolic system. Daily sugar action and the long-term accumulation of body fat are targets of both</p><p>(View PDF for the rest of the abstract.)</p>
