investigating the possibility that acetylcholinesterase ( ache ) and butyrylcholinesterase ( buche ) are regulated in a coordinated manner , we have examined the natural variation in activity of these two enzymes in several tissues of adult male sprague-dawley , fischer-344 , and wistar-furth rats .
