Interacted force between a robot, human and anatomical object in orthopedic surgery provides crucial information for safe and accurate bone cutting. When the robot plays the role of assisting the surgeon in the whole surgical procedure, the robot is trying to comply with the human intention according to various cutting conditions. The reaction force to the robot from the human is for indicating human intention, whereas the force from the anatomical object reflects the cutting condition. In this paper two impedance indices are defined by these two interacted forces and a surgical robot then decides whether assistive or resistant action is activated so that accuracy and safety of bone cutting can be achieved.

Red bean (Phaseolus radiatus L. var. Aurea) is a leguminous seed and mainly used as one of the popular ingredients in oriental desserts. The objective of this study was to evaluate the anti-inflammatory activity of 50 g/kg ethanolic extract of red bean (RBE) by measuring lipopolysaccharide (LPS)-induced expressions of nitric oxide (NO), inducible nitric oxide synthase (iNOS), cyclooxygenase 2 (COX-2), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) in RAW 264.7 macrophages. On the other hand, the antioxidant activity of RBE was determined by thiobarbituric acid reactive substances method and comet assay using H2O2-induced macrophages. The results showed that RBE at the concentrations of 50–200 μg/mL can significantly suppress the inflammatory responses in LPS-stimulated macrophages through the reduction of cellular NO and downregulation of the gene expressions of iNOS, COX-2, TNF-α, and IL-6 in a dose-dependent manner. Furthermore, RBE can diminish H2O2-induced oxidative damage in RAW 264.7 macrophage. Phenolic compounds and cyanidin-3-Oglucoside from BRE may have efficacy as overall in vitro anti-inflammatory and antioxidant agents. Red bean exerts an antiinflammatory response and has potential as a health-promoting ingredient.
