Try \textmd ("medium" weight) to cancel boldness (these are called  
"font series" in NFSS), and \textup ("upright" shape) to cancel any of  
italic, slanted, or small-caps (these are "font shapes").  So if you  
wrap your embedded "normal" object in \textmd{\textup{....}} you  
should get what you want.

For more, check your friendly local LaTeX reference book for details  
about NFSS, the New Font Selection Scheme (though it was "new" a long  
time ago now!).
