| Outline of Final Research Achievements |
In this study, horseradish peroxidase (HRP) was administered into the cistern magna in rats, and HRP penetration in the brain parenchyma was measured. The results showed that the penetration area of HRP in the brain parenchyma increased with time, and the HRP signals were observed in areas surrounding the lobule in the pars tuberalis. In contrast, HRP signals were not observed when HRP was injected intravenously. We also analyzed peptide extracts from the pars tuberalis and the cerebrospinal fluid by mass spectrometry. We showed that several peptides from the pars tuberalis were also found in the cerebrospinal fluid.
