[Effect of anabolic steroid on immune response]

Using lymphocyte, monocyte and eosinophil counts of the peripheral blood, PHA-blastoid transformation, immunoglobulin and beta 2-microglobulin, the influence of anabolic steroid on the immune reactivity of the host was dissected by administration of Deca-Durabolin ( nandrolone decanoate) to both tumor-bearing host and tumor-free host after operation for alimentary tract. The number of peripheral lymphocytes and monocytes, the PHA-blastoid transformation of peripheral lymphocytes and the IgG level were increased, and the beta 2-microglobulin level showed the tendency of decrease after the administration of Deca-Durabolin.
