A case of idiopathic periodic paralysis was studied by using various clinical and laboratory examinations, and the, conclusion of our studies are as follows:
(1) Leucocyte count increased during the spontaneous attack, however it showed normal value when the attack was abated.
(2) Cerebrospinal pressure was elevated during the attack was going on and it returned to normal thereafter.
(3) Seru m potassium did not show any remarkable entrance into the erythrocyte when the attack was provoked by the glucose infusion containing insulin.
(4) ECG showed typical hypokalemic pattern during th e provoked paralysis, that is prolongation of P-R interval, depression of the RS-T segment and the appearance of U wave and so on.
(5) EMG showed normal pattern before the provocation, but it showed diminution of frequency of NMU, low amplitude NMU voltage and polyphasic pattern at the onset of the provocation and then it finally showed electrical silence even by the voluntary contraction and then the patient became fainted. But five hours after the provocation his EMG began to show low amplitude NMU voltage by administration of Solita T3 and KCL tablets.
24 hours later, his EMG showed recovery of the amplitude of NMU, the interference wave by the strong contraction, and polyphasic pattern became obvious and his fatigability was restored almost completely.48 hours later EMG showed nearly normal pattern.
