Effects of amino acids on the volume and pH of gastric contents in pylorus-ligated rats.

Drugs	Doses (mg/kg)	No. of rats	Volume (mL)	Gastric pH
Control	–	5	6.38±0.87	1.30±0.05
L-arginine	250	4	6.30±0.41	1.82±0.05*
L-alanine	500	5	8.56±0.48	2.36±0.12*
L-glutamine	750	5	8.66±0.81	1.73±0.09*
Glycine	750	4	8.63±0.41	2.38±0.07*

Amino acids were given orally immediately after the pylorus was ligated. The gastric contents were collected 3 h after the ligation. Following centrifugation for 10 min at 3,000 rpm, the volume of each sample was measured, and the pH was determined by using a pH meter. Values are presented as the mean ±SE for four to five rats.
