A transgenic non-human animal with alterations in the MBL gene is prepared by introduction of a gene encoding an altered MBL protein into a host non-human animal. An ink-repellent layer is formed on an ink ejecting side surface of the nozzle plate, and portions of the ink-repellant layer around the ink ejecting holes are selectively removed so that portions of the nozzle plate around the ink ejecting holes are exposed. Another solid dispersion contains amorphous paroxetine mesylate and a -vinylpyrrolidonevinylacetate copolymer, where the weight ratio of paroxetine mesylate to copolymer ranges from about 30:70 to about 50:50. The anchor includes a plurality of flexible legs adapted for coupling to the plunger when the plunger is fully displaced to its distal end position within the syringe barrel.
