くも膜下出血剖検症例の臨床病理学的研究（第2報）—剖検脳に認められる鉄顆粒細胞の意義について

A Clinico-pathological Study on Subarachnoid Hemorrhage in Autopsied Cases:The Significance of Iron Conta ining Granule Cells Seen in Autopsied Brain with Suharachnoid Hemorrhage

Ⅰ．緒言

　くも膜下出血剖検脳に認められる病理所見のうち脳軟化巣と脳実質内出血巣は主要な所見であり^{1，2，15，17，19，20）}，またこれら病理所見がくも膜出血の続発性変化であることは今日異論がない．

　一方，くも膜下出血症例の臨床的観察^{4，12-14，22）}や実験的くも膜下出血例の成績より^3，8，9），くも膜下腔に出た血液が容易に脳血管を攣縮せしめるというきわめて興味深い事実がある，脳血管攣縮というこの臨床的現象は前述のくも膜下出血剖検脳に認められる脳軟化巣や脳実質内出血の発生機序を説明するのに重要な所見である．

Cerebral infarction and petechial hemorrhage are seen in autopsied brains with subarachnoid hemorrhage as most important findings. However, the pathogenesis for the development of these lesions are still obscure.

We have been doing clinico-pathologic-al study on the cerebral petechial hemorrhages following subarachnoid hemorrhage. In this report, the findings of these hemorrhagic lesions were presented in detail by means of Perls-Stieda's iron staining.

The results are as follows.
