MODIFIED HEMATOXYLIN AND EOSIN STAIN FOR ELASTIC FIBERS IN RAT CAROTID AND PIG CORONARY-ARTERIES AFTER BALLOON INJURY

We modified and automated a conventional hematoxylin and eosin stain f or formalin fixed, paraffin embedded rat carotid and pig coronary arte ries. This method enhanced the staining of the elastic laminae in inju red pig coronary and rat carotid arteries, and improved morphometric m easurements of the media and neointima by computerized image analysis. This modified hematoxylin and eosin stain can replace complicated ela stic stains such as Verhoeff-Van Gieson or Movat pentachrome as a meth od for routine staining of arteries for morphometric analysis.
