Abstract

最近,話題を集めている大脳表面の毛細血管の血流変化を非侵襲的に観察する装置は,体内を透過し易い近赤外光の特性を利用している.この光は四肢や体幹の大量の血流変化も観測できる.本論文では,微弱近赤外光を用いて,門脈の血流変化を安全かつ連続的に計測する方法について述べる.微弱近赤外光を用いる計測法で得られる門脈の血流変化は定性的で定量的ではないという限界はあるけれども,腸の消化機能が把握できるし,健康状態の推定や疾病の早期発見に役立つ可能性もある.また,本研究用に開発した計測装置は安価な部品で構成できることから,一般家庭で広く利用できる機器に仕上げられる可能性も高い.

Near infrared spectroscopy is presently applied to detect cerebral blood flow changes of the capillary network. We have found that this method is applicable to detect larger blood flow changes at the extremities or the trunk in a human body. In this study, we measured portal vein blood flow change safely and continuously. We were able to detect portal vein blood flow changes qualitatively but not quantitatively. Even with this limitation, it is expected that blood flow change reflects digestive function of the intestines and may help examine the general condition of a subject and provide the impetus for an early checkup. The equipment with this device used in our study is inexpensive, therefore, it may be suitable for home-use.
