Abstract

Peripheral blood lymphocytes from 13 children with newly diagnosed untreated non‐Hodgkin malignant lymphoma were investigated for the proportion of Tμ and Tγ cells. Tumor involvement was classified as stage II in two patients, stage III in five patients, and stage IV in six patients. Diffuse poorly differentiated lymphoblastic histological‐type lymphomas, as defined by the Rappaport classification, were found in eight patients. The proportion of Tγ cells was found to be increased and that of Tμ cells decreased in the patient group as compared to levels in healthy controls. A marked imbalance of the Tμ/Tγ ratio was observed in ten of 13 patients. There was no correlation between Tμ/Tγ ratios and stage of the disease. Imbalances of Tμ and Tγ cell proportions are discussed in relation to humoral and cellular immunodeficiencies observed in patients with non‐Hodgkin malignant lymphoma.

The soluble form of Fas (sFas) can block apoptosis induced by the Fas ligand in vitro. A recent report demonstrated that mice injected with sFas displayed autoimmune features. Therefore, an elevated serum concentration of sFas may be associated with lymphoproliferation and autoimmune diseases. We me

Detection of residual disease in follicular lymphoma is hampered by the observation of t(14;18)-bearing cells in the blood of healthy adult humans. To overcome this problem, we decided to validate a quantification method of t(14;18)bearing cells and test it in t(14;18)-bearing follicular lymphomas (

## Abstract It is well documented that cytotoxic treatment in patients carrying the hepatitis B virus (HBV) enhances the risk of severe hepatic damage. Recently lamivudine has been reported to be effective in suppressing the replication of HBV under such conditions. Here we report two cases with HB
