    Notes: Summary An immunohistochemical study with a polyclonal anti-β-protein antiserum was performed in order to understand the mechanism of deposition of amyloid fibrils in senile plaques in Alzheimer-type dementia (ATD). Serial cortical sections cut from ATD brains were necessary to investigate the structural correlation between senile plaques and blood vessels. The senile plaques were stained well and a blood vessel or capillary-like structure was found in most of β-protein-immunoreactive deposits. These findings may suggest an involvement of blood vessels in the formation of at least some of the amyloid deposits in ATD brains.

    Notes: Summary Postmortem stability of arginine-vasopressin (AVP) messenger RNA (mRNA) in the rat brain was studied comparing changes with those in the recovered amounts of total RNA and ribosomal RNA (rRNA). The amount of AVP mRNA and rRNA showed a decrease with increasing time interval after death (postmortem time), whereas the amount of total RNA did not alter with postmortem time. The half-life of AVP mRNA in the rat postmortem seemed to be approximately 16 hrs. The analysis of the ratio of AVP mRNA to 18S-rRNA suggested that AVP mRNA was degraded postmortem more rapidly than rRNA. These results suggest that autopsied human brains should be used for AVP mRNA study within a short postmortem time.
