The long-term results obtained in a series of 174 patients operated on for spinal meningiomas are critically analyzed. This series was similar to those of other authors with regard to age, sex, location of the tumors, and clinical presentation.

This study outlines the vascular territories of the cerebral arteries that originate from the Willis circle to supply limbic structures in the guinea pig brain. The entire cerebral vascular system was visualized in four preliminary experiments by performing superselective microangiographic studies with iodine contrast medium perfusion of the whole brain(More)
A human reference serum pool, lot 89-S, has been developed for use in quantitating concentrations of antibody to Streptococcus pneumoniae. Weight-based units have been assigned to antibodies to 11 pneumococcal polysaccharide (PnPs) serotypes (1, 3, 4, 5, 6B, 7F, 9V, 14, 18C, 19F, and 23F) by using enzyme-linked immunosorbent assay methodology and a human(More)
We compared the diagnostic sensitivity of magnetic resonance imaging (MRI) and evoked potential (EP) studies in a series of 19 children affected by clinically definite (16 cases) and laboratory supported (3 cases) multiple sclerosis (MS). MRI revealed abnormal areas consistent with demyelinating plaques in 18 out of 19 cases: multiple lesions in 16 and an(More)
