Age-related changes in duodenal adaptation after distal small bowel resection in ratDigestive Diseases and Sciences - Tập 38 - Trang 410-416 - 1993
Keigo Yoshinaga, Jin Ishizuka, Courtney M. Townsend, James C. Thompson
Two groups of male Fisher 344 rats (young: 4 months old; aged: 25 months old)
underwent either 70% distal small bowel resection or sham operation (small bowel
transection). Rats from each treatment group of each age were sacrificed on the
10th (N=15: young rats;N=13: aged rats) or 20th (N=15: young;N=13: aged)
postoperative day (POD), and the duodenal mucosa was weighed and assayed for
DNA, RNA, a... hiện toàn bộ
Hemodynamic effect of propranolol on portal hypertension in patients with HBsAg-positive cirrhosisDigestive Diseases and Sciences - Tập 31 - Trang 1303-1306 - 1986

Wedged hepatic venous pressure, free hepatic venous pressure, and cardiac index
were measured before and one hour after intravenous and one month after chronic
oral administration of propranolol in nine patients with HBsAg-positive
cirrhosis. The gradient between wedged hepatic venous pressure and free hepatic
venous pressure was decreased 22.7% at one hour after intravenous administration
of 5 mg... hiện toàn bộ
Delta-Opioid Receptor mRNA Expression and Immunohistochemical Localization in Porcine IleumDigestive Diseases and Sciences - Tập 43 - Trang 1402-1410 - 1998

Opiates have potent antidiarrheal actions thatare mediated in part by
delta-opioid receptors (DOR). Weexamined DOR localization within subregions of
porcineileum, a tissue analogous to human small bowel. A partial cDNA sequence
for porcine DOR wasobtained after reverse transcription-polymerase chainreaction
cloning of forebrain RNA; it encoded the end oftransmembrane domain 1 through
the beginning... hiện toàn bộ
Clinical course of esophageal stricture managed by bougienageDigestive Diseases and Sciences - Tập 27 - Trang 884-888 - 1982
Michael E. Glick
To define the clinical course of patients with benign esophageal stricture
treated with bougienage, we reviewed the records of 76 patients undergoing
dilatation. Patients with the diagnosis of scleroderma and those with previous
hiatal hernia repair or gastric surgery were excluded. Initial evaluation
included contrast study, esophagoscopy, and biopsy. Patients underwent a series
of dilatations un... hiện toàn bộ
Effect of experimental cold pain stress on gastroesophageal junctionDigestive Diseases and Sciences - Tập 39 - Trang 641-647 - 1994
P. Zacchi, F. Mearin, J.-R. Malagelada
The impact of stress on gastroesophageal reflux and antireflux mechanisms
remains largely unexplored. To a major extent, reflux depends on a balance
between gastroesophageal junction resistance to flow and gastric tone. We
hypothesized that these two forces could be differently affected by stress, and
to test the hypothesis we quantified in 10 healthy volunteers the effect of an
acute stressful st... hiện toàn bộ
