    摘要: Fusion antigen used as vaccine. The invention relates to a fusion antigen specific for a target cell. The fusion antigen contains a ligand moiety, a Pseudomonas exotoxin A translocation domain II, an antigenic moiety, and a carboxyl terminal moiety. The ligand moiety is capable of reacting, recognizing or binding to receptors on the target cell. The carboxyl terminal moiety permits retention and processing of the fusion antigen in the endoplasmic reticulum (ER) membrane of the target cell. Pharmaceutical compositions and methods of inducing an immune response using the same are also disclosed.

    摘要: An ultrasonic nebulizer for producing high-volume sub-micron droplets is disclosed. The ultrasonic nebulizer utilizes a 3 or 5 MHz frequency as an oscillation frequency for producing sub-micron droplets. The nebulizer can also use at least one piezoelectric ceramic oscillator for increasing the volume of the droplets. The ultrasonic nebulizer comprises an ac/dc converter, an oscillator circuit, an amplifying device, a nebulization chamber, and at least one piezoelectric ceramic oscillator. The ac/dc converter rectifies an ac current to a dc current. The oscillator circuit produces an oscillation signal with a frequency larger than or equal to 3 MHz. The amplifying device amplifies the oscillation signal. The nebulization chamber has a lower face for holding a liquid to be nebulized. At least one piezoelectric ceramic oscillator is formed on the lower face of the nebulization chamber and connected to the amplified signal providing an ultrasonic output to cause nebulization for producing high-volume sub-micron droplets.
