▪ In man and other species, there is accumulating evidence that gastrin stimulates acid secretion by releasing histamine.
▪ Beverages with higher alcohol content such as whisky and cognac did not stimulate acid secretion.

▪ After premedication with atropine intravenous ethanol failed to stimulate acid secretion.
▪ Further characterisation of the non-ethanolic component of beer and wine that stimulates acid and gastrin secretion needs to be carried out.
▪ This is because the very low concentrations of these substances present in beer failed to stimulate acid secretion.
▪ Early studies by Cooke showed that ethanol in concentrations of 1% to 20% did not stimulate gastric acid secretion.
EXAMPLES FROM OTHER ENTRIES

EXAMPLES FROM CORPUS
▪ In man and other species, there is accumulating evidence that gastrin stimulates acid secretion by releasing histamine.

Secretion \Se*cre"tion\, n. [L. secretio: cf. F. s['e]cr['e]tion.]

  1. The act of secreting or concealing; as, the secretion of dutiable goods.

  2. (Physiol.) The act of secreting; the process by which material is separated from the blood through the agency of the cells of the various glands and elaborated by the cells into new substances so as to form the various secretions, as the saliva, bile, and other digestive fluids. The process varies in the different glands, and hence are formed the various secretions.

  3. (Physiol.) Any substance or fluid secreted, or elaborated and emitted, as the gastric juice.

Secretion

Secretion is the movement of material from one point to another chemicals, or a secreted chemical substance from a cell or gland. In contrast to excretion, it is the removal of certain substances or waste products. The classical mechanism of cell secretion is via secretory portals at the cell plasma membrane called porosomes. Porosomes are permanent cup-shaped lipoprotein structure at the cell plasma membrane, where secretory vesicles transiently dock and fuse to release intra-vesicular contents from the cell.

Secretion in bacterial species means the transport or translocation of effector molecules for example: proteins, enzymes or toxins (such as cholera toxin in pathogenic bacteria for example Vibrio cholerae) from across the interior ( cytoplasm or cytosol) of a bacterial cell to its exterior. Secretion is a very important mechanism in bacterial functioning and operation in their natural surrounding environment for adaptation and survival.
