| Outline of Final Research Achievements |
It was confirmed that some kinds of peroxidase-labeled streptavidin and IgG has abilities of non-specific adsorption to glassy matter. The methods of staining for diatom frustules were established. Then this staining method was applied to diatom tests that have been actually drowned victims. As a result, detection of the diatom frustules was easier, and the time to diagnose drowning was greatly shortened.
In addition, we could submit a paper on novel species of diatom discovered from sample water obtained from a drowning site during this research. Subsequent research confirmed that this diatom was also found in a completely different water system in Oita prefecture, and expansion of the habitat was found. Currently, we are conducting comparative study on the genetic diversity of diatoms discovered from each water system.
