Abstract
Plasma protein shedding in the stomach was measured in 23 normal individuals before and after intragastric administration of a 30% solution of ethyl alcohol. Two different methods were used to assess plasma protein shedding. The first technique utilizes [131I]albumin and requires neutralization of the gastric juice. It was used in 12 subjects and failed to demonstrate any increase of plasma protein shedding under the influence of ethanol. The second technique which utilizes [51Cr]chloride was used in 11 subjects. It demonstrated a significant increase of the gastric clearance of plasma protein which reached 2.5 times the control values. The [51Cr]chloride technique does not require prior neutralization of gastric acidity. It is concluded that, in normal man, ethanol administration increases plasma protein shedding in the stomach when it is given in the presence of an acid gastric juice. The effect is not observed when the gastric acidity is neutralized.
