I think these collection of domain names would bring in about $5,000 to $10,000 to the right end user but I first suggest building up a text heavy site based on your intended buyers such as the medical things you spoke of.
Just keep in mind that finding the right end user won't be easy and can take some time. In the mean time you can continue to build up the value of these domains by having your text heavy websites listed in the major search engines.
