A method of treatment of a host with a cellular proliferative disease, comprising contacting the host with a cephalotaxine and an antiproliferative agent, each in an amount sufficient to modulate said cellular proliferative disease, is described. The male connecting set includes a first direction male connector and a second direction male connector, and the female connecting set includes a first direction female connector corresponding to the first direction male connector, and a second direction female connector corresponding to the second direction male connector. Furthermore, in the vehicle rear seat, distal end sides of the hinge pins, that is, portions that protrude outward of the rear seat back, are respectively covered with covers attached to the corresponding retainers. A process head lifter lowers the head holding the workpiece into the processing fluid in the bowl. The first operating and observation system having the extensive functionality is designed to be mobile, thereby doing away with mobility restrictions. Thus, the electric nailer provides a larger impact force with a smaller volume and a lighter weight.
