In a case of chronic thrombocytopenic purpura, significant lymphocyte transformation could be induced with autologous platelets as a stimulant. The reaction was not due to serum factors since it occurred when culture medium was supplemented either with autologous or pooled human serum. Controls excluded nonspecific lymphocyte transformation. Modulation of normal platelet antigens by viral or ch...

Nodular lymphocyte-predominant Hodgkin lymphoma is an uncommon variant of Hodgkin lymphoma. Progressive transformation of germinal centers has been associated with and can develop prior to, concurrent with, or after the diagnosis of nodular lymphocyte-predominant Hodgkin lymphoma. We present a patient with a history of progressive transformation of germinal centers of the right parotid who pres...

A study was made of PHA-stimulated formation is age-related. Until the 18th thymic lymphocyte transformation in 10 week of gestation, the per cent of transhuman fetuses ranging from 12 to 22 formed thymic lymphocytes is comparaweeks of gestation. The results were ble to that of blood lymphocytes. After compared with those obtained using cirthe 18th week of gestation, the per cent culating blood...

Children with kwashiorkor showed a high incidence of deranged cellular immunity as evidenced by impairment of delayed cutaneous hypersensitivity reactions to candida and diphtheria toxoid antigens and of lymphocyte transformation after phytohaemagglutinin stimulation. This may contribute to their susceptibility to infection. A correlation was shown between the degree of impairment of tests of c...

Forty-three patients with an initial diagnosis of tropical splenomegaly syndrome were placed on long-term proguanil therapy. All patients who failed to respond to proguanil and who were adequately followed up developed identifiable disease, usually malignant lymphoma or chronic lymphatic leukaemia. In patients who responded to proguanil IgM values were always very high and phytohaemagglutinin (...

The influence of DDS on PHA-induced lymphocyte transformation was investigated in leukocyte cultures from two samples of healthy Caucasoid individuals. In one sample the sulfone-treated cultures differed from the controls in that they contained 0.4 mug/ml of other sample, the treated cultures contained DDS in concentrations of 4 mug/ml, 8 mug/ml and 16 mug/ml. The frequency of lymphocyte transf...
