I didn't realize that I may have been at least partly responsible for
the fears suroundinf AA. I am familiary with these articles as I have
been collecting such amterials for well over a year.

I do not have the last article you posted in Lipids (1997). AA from
dietary sources does not appear to be a problem as far as I'm concerned.

RBC AA content does not present a significant problem as RBCs are devoid
of cyclooxygenase content. Remember, I'm concerned with endogenous
production of AA.
