in vitro analysis of allogeneic lymphocyte interaction. iv. dual recognition of b cell-associated mls locus and i-region determinants by a helper allogeneic effect factor (aef) generated across a minor h locus disparity.a helper allogeneic effect factor (aef) was produced across an incompatibility at the minor histocompatibility loci. this aef is genetically restricted in its activity since it helps b cells only of the stimulator haplotype and of haplotypes that share both an mls and i-region identity with the stimulator haplotype. the i-region genes involved here map to the i-a and/or i-c subregions. an anti-lym immunoadsorbent column but neither an anti-h-2 nor an anti-ia column absorbed aef helper activity. ...200087470
pattern and flash visual evoked responses in multiple sclerosis.in multiple sclerosis (ms), increase of delay may be important, but the earlier change is the behavior of the wave shape; amplitude is always lower even in ms patients without visual subjective symptomatology, provided not only flash but also pattern stimulation is performed. normal amplitude with pattern stimulation does not necessarily mean normal with flash. combining both stimulation methods, we obtained lowering of amplitude and change of wave shape in 100% of cases while latency was increa ...200087495
