| Outline of Final Research Achievements |
Unknown factors or diseases that were not recognized to cause sudden infant death were investigated. It was thought that infection of Cronobacter sakazaki as cause of sudden death could be simply diagnosed only by the growth of that pathogen in the culture. Fulminant type Ⅰ diabetes could also be diagnosed by the extreme low level of blood 1,5-AG concentration, whereas evaluation of stress as the factor of sudden death should be examined further using saliva chromogranin A concentration.
According to the investigation of the ratios of area of the left ventricle to those of the right ventricle and the total left heart in the heart cross-section, it was suggested that the the left heart dysfunction could be another possible unknown factor/cause of infantile sudden death.
