Summary

Light and electron-microscopic studies were performed on the muscles taken from 4 cases with hypokalemic periodic paralysis. The authors conclude that the earliest changes concern the sarcoplasmic reticulum: vacuolisation of the longitudinal system and probably, multiplication of the transverse system. It is suggested, that vacuoles are formed as a result of fusion of the vesicles of the transverse system. Destruction of myofibrilles and enlargement of the interfibrillar spaces appear at a later period of the disease process. Extensive and intensive changes of that kind present a typical appearance of myogenic changes in histological study observed in the cases with clinically fixed symptomes of myopathy.

Zusammenfassung

Licht- und elektronenoptische Untersuchungen wurden an Muskelbiopsien von 4 Fällen hypokaliämischer periodischer Paralyse durchgeführt. Die frühesten Veränderungen betreffen nach Meinung der Verfasser das sarkoplasmatische Reticulum: Vacuolisierung des Längssystems und vermutlich Multiplikation des Quersystems. Es wird vermutet, daß die Vacuolenbildung die Folge einer Fusion der Vesikeln des Quersystems darstellt. Destruktion von Myofibrillen und Vergrößerung der, interfibrillären Räume treten erst in späteren Phasen des Krankheitsprozesses auf. Ausdehnung und Intensität dieser Veränderungen bedingen das typische histologische Bild myogener Läsionen bei Fällen m klinisch fixierten Symptomen der Myopathie.
