A new and convenient myelin stain is described. Paraformaldehyde fixed tissue is serially immersed in a nitroblue tetrazolium solution and then in a diaminobenzidine solution. The result is distinct blue staining of myelinated fiber tracts. This technique has advantages over presently used myelin stains.

Guinea-pigs sensitized by a subcutaneous injection of ovalbumin in Al(OH)3 and boosted 2 weeks later exhibit marked bronchial hyperresponsiveness to various agonists and intense bronchial wall infiltration by CD4+ T-lymphocytes and eosinophils. We have compared the effect of FK506, a novel immunosuppressive agent, on the mucosal infiltration by T-cells and eosinophils with the well established ...
