[Intragastric bile acids and lysolecithin in clinical stress ulcer risk (author's transl)]

In 10 intensive care patients with a risk of stress ulcer intragastric concentrations of lecithin, lysolecithin and bile acids were determined and compared to values in seven normal persons. All results were increased to multiple normal values. In particular lysolecithin and bile acids showed highly abnormal concentrations. These substances have a pathogenic importance for the occurrence of stress ulcers.
