Outline of Final Research Achievements	Patent ductus arteriosus is a frequent and serious disease affecting the life and developmental prognosis of premature infants, but the influence of amino acids on the closure of the ductus arteriosus has not been clarified so far. This study revealed that glutamate induces rat ductus arteriosus contraction due to noradrenaline production. Administration of glutamate may be useful for prevention of patent ductus arteriosus in human premature infants.
