Abstract
A. A. Philchenkov
ELEVATED LEVEL OF TGF-ALPHA IN RAT SMALL INTESTINAL
MUCOSA FOLLOWING MASSIVE SMALL BOWEL RESECTION
This study was performed to determine the changes in TGF-alpha production during
compensatory regeneration of small intestine. For this purpose rats underwent either
70% small bowel resection or sham operation. Levels of TGF-alpha production were
evaluated by radioreceptor assay and Western blotting. When compared with sham
operation, small bowel resection resulted in threefold increase in the production of
TGF-alpha at postoperative day 3. Possible mechanisms of TGF-alpha involvement in
intestinal adaptation following massive small bovel resection are discussed.
