The invention provides a method of treating psoriasis in a subject by administering to a subject an antibody capable of binding to the p40 subunit of IL-12 andor IL-23. The surgery apparatus comprises a tube, a tubular probe or similar working device that can be inserted into an endoscope, with a first channel such that by way of the first channel, as a first working means, there can be guided to the tissue an electrode connected to an HF generator in order to generate a high-frequency current, as well as argon or a similar inert gas. The template further having a locking mechanism to hold needles in place after they have been inserted into the body structure, the locking mechanism utilizing a channel to guide a floating plate in vertical motion with respect to a contiguous stationary plate. As such, the top panel and the side panel may be easily pulled away from the rest of the container thereby providing easy access to the contents container therein.
