title: Preparation of isolated intestinal villi useful for studying hydrolysis rates of penicillin and cephalosporin esters.
abstract: A method for the preparation of freeze-dried intestinal villi from hamsters and mice is described. The villi, consisting largely of epithelial cells rich in esterase activity, are useful for hydrolysis studies of penicillin and cephalosporin esters.
