I cannot reproduce this.  If I type `C-c C-p C-d' in a buffer with the
following example file, the "bar" string is shown in italics.

--8<---------------cut here---------------start------------->8---
\documentclass{article}
\newcommand{\defi}[1]{\emph{#1}}
\usepackage[active]{preview}
\PreviewMacro[!]{\defi}
\begin{document}
foo \defi{bar} baz
\end{document}

%%% Local Variables: 
%%% mode: latex
%%% TeX-master: t
%%% End: 
--8<---------------cut here---------------end--------------->8---

If the algorithm does not show up in the typeset document, then
preview-latex will likely also have problems showing it.  Or do you mean
that the algorithm is shown in the typeset document but not rendered by
preview-latex?

With preview-latex or with font locking?  If it is the latter, you can
customize `font-latex-math-environments' as mentioned in the AUCTeX
manual.
