The invention provides a PLGA (polylactic acid-hydroxyacetic acid) nano-drug carrier which is composed of PLGA nano microsphere kernel and an anillic aldehyde crosslinked chitosan housing. A preparation method of the polylactic acid-hydroxyacetic acid copolymer nano-drug carrier is as follows: dispersing a PLGA organic phase which takes dichloromethane and alcohol as a mixed solvent in a water phase to prepare PLGA microspheres by taking PVA (polyvinyl acetate) as an emulsifier by virtue of an one-off emulsion process; then, adding the PLGA microspheres into chitosan liquor, so that the chitosan is adsorbed on the surfaces of the PLGA microspheres, and then adding the chitosan on the surfaces of anillic aldehyde crosslinked PLGA microspheres. The product has a certain pH environmental responsiveness, can realize controlled release of the drug according to in-vivo pH environmental changes, is high in stability, strong in up-taking capacity for microsphere-coated medicaments by the cells, and has very good application prospect in the drug carrier for treating tumors.

The present invention is drawn to the nucleic and amino acid sequences encoding vaginolysin (VLY) toxin from Gardnerella vaginalis, and biologically active fragments and variants thereof. The invention is also directed to anti-VLY antibodies and to their use therapeutically and in a new ELISA assay of VLY toxin. Other embodiments of the invention are directed to VLY toxoids and to vaccines that use the new VLY toxoids as immunogens.
