Abstract: Nucleated cells can resist lysis by and recover from complement attack even after formation of the potentially cytolytic membrane attack complex on the cell surface. We have found that human neutrophils resist complement lysis by the physical removal of membrane attack complexes by both endocytic and exocytic process. The latter mechanism predominates, vesiculation being detectable within 60 sec of initiating the complement cascade. Sixty-five percent of the formed complexes are removed on plasma membrane vesicles, although only 2% of the cell surface is lost. Ultrastructural examination revealed that these vesicles were covered with ring-like "classical" complement lesions. Analysis of these vesicles by gel electrophoresis indicated that C9 was present exclusively in the form of a sodium dodecyl sulfate-resistant, high m.w. complex. In contrast, the 35% of C9 that remained associated with the cells was found to be inaccessible to a C9-specific monoclonal antibody, and was partly degraded, suggesting internalization of the membrane attack complex and proteolysis of some C9 molecules. The molar ratio of C9 to C8 was 12 to 1 on shed vesicles and on recovered cells.

Abstract: Subacute combined degeneration of the cord is a rare complication of folate deficiency. Disturbance of methylation reactions in nervous tissue probably underlie subacute combined degeneration of the cord arising from folate as well as vitamin B12 deficiency. Methyl tetrahydrofolate is the form in which folic acid is transported into the CNS. Therefore methyl tetrahydrofolate treatment of the neurological and psychiatric manifestations of folate deficiency would seem to be theoretically advantageous. A case of subacute combined degeneration of the cord due to dietary folate deficiency and associated with an organic brain syndrome is reported. There was striking haematological, neurological and psychiatric response to methyl folate treatment.

Abstract: A thyroid nodule comprised numerous polyclonal plasma cells inside cellular fibroblastic stroma, with residual thyroid tissue in the centre of the nodule. There was no associated paraproteinaemia. The residual thyroid tissue suggests that the exuberant granulation tissue in this case represents an unusual reaction to a colloid nodule. As far as we know, this is the first adequately documented case of the so called plasma cell granuloma of the thyroid.
