Santa Ana C, Morawski S, Fordtran J
Ann Intern Med . 1983 Jul; 99(1):14-7. PMID: 6190422
Self-induced purging with laxatives is common among bulimic persons, who assume that purging reduces intestinal absorption of ingested calories. However, the efficacy of purging in reducing calorie absorption has never...

Davis G, Morawski S, Santa Ana C, Fordtran J
J Clin Invest . 1983 Feb; 71(2):201-7. PMID: 6401766
During perfusion of a plasma-like solution, colonic absorption rate of chloride was much higher than the secretion rate of bicarbonate (34 vs. 3.5 meq/h, respectively). This might suggest that anion...

Diamond J, Ehrlich B, Morawski S, Santa Ana C, Fordtran J
J Membr Biol . 1983 Jan; 72(1-2):153-9. PMID: 6854620
There is significant absorption of Li+ by human jejunum and ileum, but negligible absorption by human colon. Thus, a proximal-to-distal gradient of decreasing Li+ absorption and increasing junctional tightness exists...

Santa Ana C, Morawski S, Fordtran J
N Engl J Med . 1982 Dec; 307(23):1413-6. PMID: 6182469
It has been known for more than 25 years that certain plant foods, such as kidney beans and wheat, contain a substance that inhibits the activity of salivary and pancreatic...

Schiller L, Davis G, Santa Ana C, Morawski S, Fordtran J
J Clin Invest . 1982 Nov; 70(5):999-1008. PMID: 7130398
To determine whether the antidiarrheal action of opiate drugs in humans is due to enhanced intestinal absorption rates, as suggested by recent experiments in animals, or is due to altered...

Davis G, Santa Ana C, Morawski S, Fordtran J
Gastroenterology . 1982 Oct; 83(4):844-50. PMID: 6809521
In order to assess the passive permeability characteristics of the human intestine in vivo, we measured potential difference in the jejunum, ileum, proximal colon, and distal colon during perfusion of...

Davis G, Santa Ana C, Morawski S, Fordtran J
J Clin Invest . 1981 Jun; 67(6):1687-94. PMID: 6787081
The effect of intravenous vasoactive intestinal polypeptide (VIP) on normal transport mechanisms in the human jejunum in vivo was examined with the triple-lumen, steady-state perfusion technique. By using special test...

Davis G, Santa Ana C, Morawski S, Fordtran J
Gastroenterology . 1980 Jul; 79(1):35-9. PMID: 7380220
Polyethylene glycol (PEG) is commonly used as a nonabsorbable volume marker in intestinal perfusion and flow studies. It has been assumed that PEG does not affect water and electrolyte movement,...

Davis G, Santa Ana C, Morawski S, Fordtran J
Gastroenterology . 1980 May; 78(5 Pt 1):991-5. PMID: 7380204
Ingestion of large volumes of a balanced electrolyte solution has previously been shown to be an effective method of cleaning the colon for diagnostic studies. However, in this paper we...

Read N, Krejs G, Read M, Santa Ana C, Morawski S, Fordtran J
Gastroenterology . 1980 Feb; 78(2):264-71. PMID: 7350049
We studied 27 patients with severe chronic diarrhea for which extensive investigations carried out at other institutions had failed to reveal a diagnosis. They were studied by standard diagnostic methods...
