the show

hey, does anyone have an opinion on the verb "show"?

i'm having trouble determining whether there's an actual grammatical or stylistic basis for my dislike of this word. for example, would you keep the verb "show" in these sentences or attempt to change it:

"Gross neuropathologic examination showed brain weighing 1230 g, mildatherosclerosis....

"The substantia nigra (SN) and locus ceruleus (LC) showed a moderate loss ofpigmented neurons....

"Initial laboratory studies showed normal thyroid tests, B12, chemistries....

the author uses "show" about a billion times. i think my problem is that it (a)sounds sloppy and vernacular--this may be personal taste--and (b) it isn't always literally accurate (the SN and LC don't actually do any showing). however, there's a chance that "show" might have special neuropathological meanings, but i haven't found anything of the sort, and it's unclear from the literature whether neuropathologists are using it techinically.
