beta-beta'-iminodipropionitrile (IDPN)-induced monoamine and hydroxyl radical changes in the rat brains were studied. IDPN caused decreases in 5-HT and 5-HIAA levels in all brain regions, strongly indicating that IDPN's neurotoxicity primarily affects 5-HT containing neurons. Dopamine and its metabolites' levels decreased in the some regions, most likely(More)
Osteoporosis is an adverse effect of prednisolone therapy, although no study has been conducted on myasthenia gravis patients receiving high-dose prednisolone. We measured bone density in 36 patients (26 females and 10 males) who had undergone long-term prednisolone administration, and found a decrease in bone density in 31% of female patients and(More)
Extended thymectomy and high-dose alternate-day prednisolone administration may increase the chance of remission in myasthenia gravis (MG) patients. In cases of remission, ocular symptoms sometimes reappear after a gradual decrease or discontinuation of prednisolone administration. We compared relapsed patients with those who experienced complete remission.(More)
Experimental autoimmune myositis (EAM) is a good model of human inflammatory myopathy. We induced EAM in SJL/J mice by injection with myosin and treated inflammatory changes with FK506. The mice developed inflammatory changes after the fifth myosin injection. After treatment with FK506, inflammation was suppressed and central nuclei of the muscle fibers(More)
Quadriceps muscle biopsies from 24 patients with amyotrophic lateral sclerosis (ALS) and 15 age-matched controls were prepared for histochemistry and analyzed morphometrically. Pathological features for denervation and reinnervation were observed in most ALS patients, although considerable variation between patients was noted. Myopathic changes were also(More)
We describe a rare case of autoimmune polyglandular syndrome type 2 initially presenting as Addison disease and autoimmune thyroid disease, with subsequent development of autoimmune hepatitis and myasthenia gravis (MG) crisis in a Japanese woman. MG improved with oral prednisolone followed by plasmapheresis for immunoadsorption; thymectomy was not(More)
A 34-year-old man presented with gait disturbance. He had a low grade fever and diarrhea for a few days prior to admission. Two weeks after he started to have diarrhea, he developed gait disturbance with a left foot drop. The cerebrospinal fluid obtained on admission showed pleocytosis (30/microl) and increased protein. The motor nerve conduction velocities(More)
