精神的なストレスの評価指標としてコルチゾールというホルモンが注目されている.従来,同物質は血液,唾液,尿などの検体から定量されてきた.これに対し本研究では,皮膚に微細孔を形成し,経皮的にコルチゾールを定量する新たな手法を提案する.

The physical characteristics of a human finger are important in the work by hand. Therefore, the physical and numerical modeling of fingertip is useful for the design of various equipments, for example, a handrail of stairs, a robot hand, an operation simulator, and so on. In this study, "Coulomb friction", "absorption by fingerprint and sweat" and "elasticity of finger" are considered as the element of the friction characteristics. The aim of this study is to express the force by these characteristics as function model and to make the physical fingertip model. At first, the force by friction and absorption are measured, and the contact area between fingertip and board is calculated. Next, the function of friction force with respect to vertical force acting on the contact surface between fingertip and board is suggested. Finally, the actual finger model is made and the friction force is modeled to the function.

The present study was to evaluate endothelial nitric oxide synthase (eNOS) protein expression and hemodynamics of pulmonary circulation in rats of "Living high and Training low" (LH+TL). The Sprague Dawley strain of male rats were used at the age of 9 weeks. They were divided according to four conditions of a living low (LL) group, living low and training low (LL+TL) group, living high (LH) group and LH+TL group, for 10 days. We assessed the effects of LH+TL on exercise-induced pulmonary arterial pressure and blood lactic acids under sea-level altitude in catheter-implanted conscious rats. Also, we measured the pulmonary artery under anesthesia and analyzed eNOS protein expression by western blot analysis. The blood lactate levels in the LH+TL rats decreased after maximal treadmill running compared to LL, LL+TL and LH rats (p<0.05). The increase in pulmonary arterial blood pressure with exercise was significantly lower in the LH+TL group than in the LL group (p<0.05). The eNOS protein expressions of pulmonary artery were higher in the LH+TL group than in the LL group (p<0.05). This study indicates that LH+TL reduced the increase of pulmonary arterial blood pressure with exercise at below sea-level altitude. In addition, eNOS protein expressions were enhanced in the pulmonary arteries of LH+TL rats. Thus, we conclude that the high altitude training of LH+TL was a useful method for improvement of endurance exercise ability and this improvement may be associated with pulmonary arterial response.
