  • Objectives : This study investigated the effects of electroacupuncture on memory, depression, and plasma stress hormone levels in rats that were under immobilization stress. Materials and Methods : The immobilization-only group was given two hours of immobilization stress for 10 consecutive days. The immobilization and high frequency EA group was given two hours of immobilization stress simultaneously with high frequency (100Hz) electroacupuncture stimulation on the right ST-36 (Zusanli) for 10 consecutive days. We conducted the inhibitory avoidance and forced swimming tests to recognize whether immobilization stress and electroacupuncture have effects on memory and depression. We collected blood samples from the tail of each rat at 30, 60, 90, and 120-minute intervals during the immobilization stress and EA stimulation to measure plasma concentrations of ACTH, corticosterone, melatonin, and norepinephrine induced by immobilization stress and electroacupuncture. Results : There was a significant effect of high frequency on the increase in anamnesis based on the result of the inhibitory avoidance test, but there was no significant effect of decreasing depression based on the result of the forced swim test. Also, there was no significant effect on the response indicated by stress hormones. Conclusions : 1. High frequency electroacupuncture (100Hz) improved anamnesis in immobilization stress states under the inhibitory avoidance task. 2. High frequency electroacupuncture (100Hz) did not reduce depression induced by immobilization stress under the forced swimming test. 3. High frequency electroacupuncture (100Hz) did not decrease stress hormones through blood sampling.

  • Purpose: X-linked adrenoleukodystrophy(ALD) is a rare disorder that shows a great deal of phenotypic variability. We subdivided chidhood X-linked ALD patients into several phenotypes by the age at onset, the sites of most severe clinical involvement and the rate of progression of neurologic symptoms. Methods: Thirteen patients who had been diagnosed as X-linked ALD and followed up for at least one year were enrolled from 1996 to 2003. Results: 1. Ten had childhood cerebral ALD, who showed first neurologic symptoms at 7.02 years and progressed rapidly: interval between first symptoms and vegetative state was 1.35 years, and interval from initial symptoms to death was 3.35 years. Treatment with Lorenzo's oil did not prevent neurologic progression. Two patients who underwent umbilical cord blood transplantation died. 2. Two had adolescent cerebral ALD. They had first symptoms at 11.5 years, and showed tendency to progress less rapidly than childhood cerebral form patients. 3. One "Addison only" patient who had adrenal insufficiency without nervous system involvement remained asymptomatic during Lorenzo's oil treatment. 4. All cerebral form patients except one showed the lesions in both parieto-ocipital white matter in brain magnetic resonance imaging. Conclusion: The cerebral ALD was the most common form in childhood and was asoociated with a serious prognosis.
