Ten patients with multiple sclerosis (MS) were enrolled in a preliminary trial of the potassium channel blocker, 3,4-diaminopyridine, to evaluate drug toxicity and pharmacokinetics. The patients were treated with oral 3,4-diaminopyridine, first with increasing single doses up to 100 mg and then with divided dosage for up to 3 weeks. Paresthesias were(More)
This report describes the first use of recombinant-DNA-produced human interferon in patients with multiple sclerosis (MS). Ninety-eight patients who were clinically definite for MS with two or more documented exacerbations during the preceding two years were admitted to this placebo-controlled double-blind randomized trial. Although both groups were(More)
A double-blind, placebo controlled trial of recombinant alpha 2 interferon in relapsing/remitting multiple sclerosis patients was performed to assess the clinical and immunological responses to treatment. This study demonstrated that natural killer (NK) cell activity, known to be enhanced by interferon (IFN) treatment, increased during the first week of(More)
The effects of immune manipulation upon survival and histopathology in two experimental group B togavirus encephalitides were studied in inbred mice. The median survival time 8 days after intracerebral injection of Langat virus increased to 10 days with an immunosuppressive course of cyclophosphamide, with concomitant reduction in the inflammatory response.(More)
Lymphocytic choriomeningitis virus-induced central nervous system disease is characterized by death during a seizure approximately seven days after intracerebral inoculation. This process is mediated by thymus dependent lymphocytes, sensitized against viral antigens. Various forms of immunosuppressive treatment prevent the seizure death and produce(More)
Because previous ultrastructural studies of murine lymphocytic choriomeningitis (LCM) had revealed only mononuclear cell infiltration with no cytopathology of target cells in the choroid plexus, ependyma, and leptomeninges, diazepam treatment was used to prolong survival for characterization of late pathogenetic events. Mice which were treated with diazepam(More)
A middle-aged woman had five discrete episodes of herpes zoster. The first attack consisted of uncomplicated herpes zoster ophthalmicus. The subsequent four episodes involved thoracic, cervical, and finally sacral dermatomes and were complicated by myelitis or encephalomyelitis. During the most recent attack, while she was receiving corticosteroids,(More)
