We investigated the time courses of the plasma ethanol, acetaldehyde, gastrin and cholecystokinin (CCK) levels after the ingestion of ethanol (1g/kg, 21.5%, whisky) in healthy male adult volunteers. The ethanol level reached a peak at 15 to 45 minutes after the ingestion and then decreased almost linearly. The acetaldehyde level of the group who became flushed after drinking (the F group) peaked earlier than that of the other group whose faces became only slightly flushed (the N group). The gastrin level increased significantly and remained elevated for about 3 hours. In three of the nine subjects, the CCK level increased 75 minutes after drinking. As a result, the absorption of the ingested ethanol is more rapid than 15 minutes, followed by a quick catabolism of the absorbed ethanol to acetaldehyde, but the catabolic action of acetaldehyde in the F group is later than that in the N group. The plasma gastrin level is certified to increase after the ingestion of ethanol and this is not mediated by acetaldehyde because the intra-venous infusion of acetaldehyde was not increased the plasma gastrin level in dogs. CCK which stimulate the pancreatic enzymes may be considered to have a possibility relating to the development of alcoholic acute pancreatitis but the ingestion of ethanol showed no increase of the plasma CCK level. But we cannot deny the possibility of the individual differences in the hormonal reaction in these experiments.

To ascertain whether any of the well-known effects of intravenous ethanol on pancreatic and gastric secretion could be due to its metabolite--acetaldehyde, a strong cytotoxic and sympathomimetic agent--acetaldehyde was given intravenously for 1 h (50, 100, and 200 mg/kg/h) in seven dogs. Acetaldehyde did not modify pancreatic secretion stimulated with secretin and caerulein, but under basal conditions 200 mg/kg/h slightly increased the volume and protein content of pancreatic juice. Acetaldehyde increased gastric secretion up to 4.03 meq/15 min in a dose-dependent manner, while serum gastrin remained unchanged. The increase of acidity persisted after propranolol and was inhibited but not abolished by ganglionic blockade. It can be concluded that physiological concentrations of acetaldehyde do not interfere with pancreatic secretion and that it is possible that the stimulatory effect of ethanol on gastric secretion is mediated at least partly through acetaldehyde.

We have searched for millimetre-wave line emission from ethylene oxide (c-C2H4O) and its structural isomer acetaldehyde (CH3CHO) in 11 molecular clouds using SEST. Ethylene oxide and acetaldehyde were detected through multiple lines in the hot cores NGC 6334F, G327.3-0.6, G31.41+0.31, and G34.3+0.2. Acetaldehyde was also detected towards G10.47+0.03, G322.2+0.6, and Orion 3'N, and one ethylene oxide line was tentatively detected in G10.47+0.03. Column densities and rotational excitation temperatures were derived using a procedure which fits the observed line intensifies by finding the minimum chi 2-value. The resulting rotational excitation temperatures of ethylene oxide and acetaldehyde are in the range 16-38 K, indicating that these species are excited in the outer, cooler parts of the hot cores or that the excitation is significantly subthermal. For an assumed source size of 20", the deduced column densities are (0.6-1)x10(14) cm-2 for ethylene oxide and (2-5)x10(14) cm-2 for acetaldehyde. The fractional abundances with respect to H2 are X[c-C2H4O]=(2-6)xl0(-10), and X[CH3CHO]=(0.8-3)x10(-9). The ratio X[CH3CHO]/X[c-C2H4O] varies between 2.6 (NGC 6334F) and 8.5 (G327.3-0.6). We also detected and analysed multiple transitions of CH3OH, CH3OCH3, C2H5OH, and HCOOH. The chemical, and possibly evolutionary, states of NGC 6334F, G327.3-0.6, G31.41+0.31, and G34.3+0.2 seem to be very similar.

Whisky (1 g/kg, 21.5% alcohol) was administered orally to healthy young adult male volunteers, and changes in the plasma concentrations of alcohol, acetaldehyde, gastrin, cholecystokinin (CCK) and serum amylase were measured over time. Values for alcohol and acetaldehyde rapidly reached a peak at 30-45 min after alcohol intake, followed by a gradual decline. The plasma gastrin concentration showed a rapid elevation, while the plasma CCK concentration did not exhibit any significant changes in the early phase after alcohol intake. Elevation of CCK was observed after 75 min, however. These results show that intake of whisky stimulates the secretion of gastrin and is associated with a later increase in CCK.
