the following parameters were assessed : cell proliferation on day 3 ( determination of in vitro [ 3h ] thymidine incorporation ) , cell migration on days 1 and 3 ( autoradiography ) , cell shedding on days 7 and 14 ( measurement of the remaining dna-bound mucosal radioactivity after in vivo labeling with [ 3h ] thymidine prior to treatment ) , mucosal morphology on day 14 ( light microscopy ) , ex vivo mucosal prostaglandin e2 on day 14 , and serum gastrin on days 0 , 7 , and 14 .
