  • Publication number: 20120202736
    Abstract: The present invention relates to a spray-dried composition comprising as an active ingredient at least one member protein of the collectin family or its functional equivalent for treating and preventing microbial infectious diseases. The present invention also relates to a method for producing the same composition. The composition produced by the method of the present invention is effective in suppressing infections caused by viruses, bacteria, fungi, and parasites. Since the composition is developed in a form suitable for inhalation, it can directly provide the active ingredient to the sites of infection from these microbes, and thus treat and prevent respiratory infections and external wounds.

  • Patent number: 5965837
    Abstract: A device for carrying artillery shells, each shell having a cylindrical body and a conical head, is disclosed. The device includes an upper body and a lower body. A gripper assembly is connected to the lower body and has an inner circumferential surface corresponding to the cylindrical body. A driving unit pivots the gripper assembly about an axis. A shell-head stopping unit is connected to the lower body at a position which may be adjusted along the length of the lower body. The shell-head stopping unit receives the conical head of a shell to hold the shell in a set position. Also included is a shell-rear stopping unit connected to the gripper assembly and elastically biased upward with respect to the inner circumferential surface of the gripper assembly. The shell-rear stopping unit holds the rear end of the shell in the gripper assembly.
