Abstract: A testing device for study of a magnetized plasma artillery and gunpowder, comprising a pedestal, wherein a top end of the pedestal is provided with a sliding slot for mounting a buffer device, which penetrates through an upper part of the pedestal along a front-rear direction. The sliding slot for mounting the buffer device is internally provided with a buffering slider, which can slide back and forth along the sliding slot for mounting the buffer device. A top end of the buffering slider is provided with a gunpowder combustion chamber fixing groove, which penetrates through an upper part of the buffering slider along the front-rear direction. The gunpowder combustion chamber fixing groove is internally provided with a gunpowder combustion chamber, and an upper part of the gunpowder combustion chamber is provided with a positioning ferrule for fixing the gunpowder combustion chamber.

Abstract: The present invention is directed to a method for promoting or stimulating a cell-mediated immune response to an antigen, by administering a target antigen (such as a protein) with a transport factor that contains a fragment of a bipartite protein exotoxin, but not the corresponding protective antigen. Preferred transport factors include the protective antigen binding domain of lethal factor (LFn) from B. anthracis, consisting of amino acids 1-255, preferably a fragment of at least 80 amino acids that shows at least 80% homology to LFn, and a fragment of about 105 amino acids from the carboxy portion that does not bind PA. The target antigen can include any molecule for which it would be desirable to elicit a CMI response, including viral antigens and tumor antigens.
