  • Abstract
  • Look Inside

Electron microscopic studies were conducted with specimen oktained by muscle biopsy from a case of thyrotoxic periodic paralysis. Light microscopy with hematoxylin and eosin stain or with Masson's trichrome stain revealed no abnormal finding except for vacuole. Thick sections stained by toluidine blue showed some dense portions, which were electron microscopically disclosed to be tubular aggregates which may originate sarcoplasmic reti-culum.

The tubules were almost in parallel with myo-fibrill measuring 58-65 mit in diameter and 70-80 Å in the thickness of limiting membrane and contain-ing the core of 26-39 mμ. Some of the tubules were enlarged to measure 0.1-0.7 μ in diameter. Besides, dilation of terminal cisternae and increase of glycogen granules were noted but degeneration of myofilament was not observed.
