IgM, IgG Serum Levels and Lymphocytes Count before and after Adenotonsillectomy.

Background: Tonsils and adenoids are involved in both local immunity and immune surveillance for the development of immune defence mechanisms. A number of investigators have found decreased immunoglobulin levels after adenotonsillectomy while others have failed to find significant changes. The effects of adenotonsillectomy on the cellular immunity of children have not been investigated extensively.

Significant association between expression of the CD11b surface molecule and favorable outcome for patients with acute myeloblastic leukemia.

The expression of several myeloid and non-lineage associated surface antigens in 70 patients with acute myeloblastic leukemia was investigated in relation to patient and disease characteristics, response to therapy, and prognosis. A leukocyte integrin, CD11b, was the only antigen that showed a significant association with complete remission (CR) duration and survival (P < .025).
