[EX Q]: Abstract: Three clinicopathologic cases with a remarkable pattern of extensive diffuse subependymal periventricular spread of cerebral metastases from solid systemic cancer are reported. Two patients had a small cell carcinoma of the lung. In the third case, the histologic features of the brain metastases were consistent with a neuron-specific enolase-positive, small cell anaplastic carcinoma. Involvement of the choroid plexus and leptomeninges was moderate or absent. Intraparenchymatous nodular metastases were not found except in one case in which rare nodular superficial cortical metastases were present. The clinical data were nonspecific except for orthostatic hypotension, in one patient, which was probably due to the infiltration of the floor of the third and fourth ventricles. Results of the cerebrospinal fluid examination, available in two cases, were normal. The only diagnostic investigation was contrast-enhanced computed tomography scanning.

[EX Q]: Abstract: A series of monoclonal antibodies (mAb) was raised in mice against Schistosoma mansoni, which recognized a carbohydrate determinant on a major Mr greater than 200,000 schistosomulum surface antigen. These mAb cross-reacted with the surface of cercariae and miracidia and with schistosomula of S. haematobium and S. bovis. Other mAb were generated that only recognized a Mr 20,000 schistosomulum surface antigen; they did not cross-react with eggs or miracidia and were species specific. The anti-Mr 20,000 mAb of the IgG1 isotype exhibited high levels of complement-dependent cytotoxicity to schistosomula in vitro. IgM mAb that recognized carbohydrate epitopes of the Mr greater than 200,000 surface antigen blocked the lethal activity of the anti-Mr 20,000 mAb. The IgM anti-Mr greater than 200,000 mAb also reduced complement-dependent cytotoxicity of serum from mice vaccinated with irradiated cercariae.

[EX Q]: Abstract: Previous serial measurements of lymphocyte subpopulations in individuals with multiple sclerosis (MS) have demonstrated periodic reductions in the number of OKT8 positive (T8+) cells. In this longitudinal study, involving twice monthly samples from each participant and carried out in two phases lasting at least six and three months respectively, we have confirmed that fluctuations in T8+ cells occur in patients with MS and also found a significant reduction in this lymphocyte subpopulation in patients' spouses but not their siblings, compared with unrelated controls. The changes observed in spouses were related in time to those occurring in patients on 10/13 occasions from 5/9 families; no temporal relationship occurred in the remainder. Taking two or more low T8+ values as significant, 12/13 patients, 7/9 spouses, 6/13 siblings and 4/13 controls (chi 2 = 12.5; P less than 0.01) were abnormal at some stage. Our results provide indirect evidence for the role of environmental factors in determining certain immunological abnormalities present in patients with MS and illustrate the role of family studies in determining the specificity of these changes to the disease.
