Abstract —The activity of thiamine pyrophosphatase was determined in segments and segment subfractions from normal and crushed sciatic nerves of the cat. Activity of the enzyme was increased in segments near the site of compression. The highest activity of the enzyme was in a fraction rich in tubular and vesicular elements resembling those observed in intact compressed nerves. On morphological grounds these structures have been interpreted as originating from Golgi‐like structures.
