Abstract: Monoclonal antibodies against human Mac-1 are provided. These antibodies can bind to different states of Mac-1 so as to alter the biofunctions of Mac-1. These antibodies can modulate Th1/Th2 cytokine secretions by TLR-activated immune cells and can be used for the treatments of diseases related to acute and chronic inflammatory disorders, such as infectious diseases, and cancers.

Abstract: An anti-slip socket capable of stably applying force in clockwise and counterclockwise directions comprises an engaging hole having an axial rectangular engaging portion on each inner wall' central portion of at least three sides thereof, so that the respective engaging portions can be synchronously engaged with the peripheral surface of the head portion of a work piece in a surface-to-surface contact manner. Therefore, besides being applied to normally drive a work piece, the anti-slip socket is still applicable when the angles of the head portion of the work piece are deteriorated and can easily drive the head portion of the work piece no matter in the clockwise direction or the counterclockwise direction, absolutely preventing the slippage with respect to the head portion of the work piece.
