Biological Activity

[Description]:

pentagastrin is a synthetic polypeptide that has effects like gastrin when given parenterally，which can cause the secretion and synthesis of salivary proteins.[1]In vivo: WIN55, 212-2, which is a non-selective cannabinoid agonist decreased gastric acid secretion stimulated by pentagastrin (10 mg/kg, i.v.) in anaesthetized rats.[2]The effect of curcumin administered i.g. in a dose of 50 mg/kg on the pentagastrin (250 ?g/kg)-stimulated gastric acid output in rats with chronic gastric fistula.
