Intragastric alcohol causes endothelin release from feline pancreas.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The mechanism by which alcohol causes pancreatic damage is still largely unknown. One important contributory factor may be the endothelins, potent vasoconstricting endothelial-derived peptides. The aim of this study was to examine in vivo endothelin release from the pancreatic vascular endothelium after alcohol ingestion. In anesthetized cats immunoreactive endothelin was measured in serum after instillation of alcohol into the stomach (20 ml, 40%). After intragastric alcohol, a rise in endothelin was seen in pancreatic venous effluent (to a mean of 24.5 +/- 7.7 pg/ml at 60 min). Control serum from the femoral artery exhibited no rise in endothelin (2.11 +/- 1.2 pg/ml). Pancreatic blood flow was significantly decreased in a further group to 93% basal after intravenous infusion of 0.1 nmol/kg ET-1 and to 61% after infusion of 1 nmol/kg ET-1. Portal serum levels of endothelin were 105 pg/ml and 15 pg/ml, respectively, immediately following bolus infusion and decreased to normal levels within 120 sec. We conclude that the serum endothelin rise after intragastric ethanol may be a major factor behind the drop in pancreatic blood flow.
