Stereometry of the red pulp on the human spleen. II) The normal spleen.

The stereometric measurements obtained in three human normal spleens surgically removed for trauma have been submitted to statistical evaluation. On the basis of the original counts, some stereometric measures of the normal splenic red pulp have been determined, namely per cent volume of sinuses, per cent volume of cords, breadth of the cords, mean sectional area of sinuses and the volume of sinuses:volume of cords ratio. These data can constitute a series of parameters to which compare the measures of the pathologic spleens.
