| Abstract |
We studied in humans the effect of exogenous secretin in a physiological dose on gastric acid secretion stimulated by pentagastrin and postprandial plasma gastrin concentration. Two doses of pentagastrin, 80 and 160 pmol/kg/hr were used to stimulate gastric acid secretion. Secretin in two doses, 2.8 and 5.6 pmol/kg/hr were tried to study the response on stimulated gastric acid secretion. Intravenous secretin in a dose of 5.6 pmol/kg/hr significantly inhibited the gastric acid output stimulated by intravenous pentagastrin in a dose of 160 pmol/kg/hr, from 11.25 +/- 1.5 to 5.99 +/- 1.34 meq/hr while lower dose of intravenous secretin (2.8 pmol/kg/hr) failed to inhibit the gastric acid output stimulated by the same dose of pentagastrin. However, the lower dose of intravenous secretin (2.8 pmol/kg/hr) inhibited the gastric acid output significantly from 8.78 +/- 1.21 to 6.37 +/- 1.62 meq/hr when gastric secretion was stimulated by the lower dose of pentagastrin (80 pmol/kg/hr). The plasma concentrations of secretin during intravenous secretin in a dose of 2.8 pmol/kg/hr was similar to postprandial plasma concentrations of secretin as previously reported. Doubling the dose of intravenous secretin resulted in almost twofold higher plasma concentrations than postprandial plasma concentrations. In addition, the low dose of secretin (2.8 pmol/kg/hr) suppressed the integrated postprandial gastrin response from 13.9 +/- 3.7 to 11.2 +/- 2.8 ng/min/ml (P = 0.05) when endogenous release of secretin was blocked by intravenous cimetidine. Since the dose of pentagastrin and secretin employed in this study fell in a physiologic range, the inhibitory effect of secretin on stimulated gastric acid secretion appears to be a physiologic action in humans.(ABSTRACT TRUNCATED AT 250 WORDS) |
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 01 March 2017.
All research outputs
#7,917,073
of 23,854,458 outputs
Outputs from Digestive Diseases and Sciences
#1,379
of 4,304 outputs
Outputs of similar age
#3,489
of 12,203 outputs
Outputs of similar age from Digestive Diseases and Sciences
#5
of 8 outputs
Altmetric has tracked 23,854,458 research outputs across all sources so far. This one is in the 44th percentile – i.e., 44% of other outputs scored the same or lower than it.
So far Altmetric has tracked 4,304 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.8. This one is in the 43rd percentile – i.e., 43% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 12,203 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 8th percentile – i.e., 8% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 8 others from the same source and published within six weeks on either side of this one. This one has scored higher than 3 of them.
