The tests performed included intradermal tuberculin tests, T- and B-lymphocyte counts, and lymphocyte blast transformation tests; phytohemagglutinin (PHA), concanavalin A (ConA) and pokeweed mitogen (PWM) were used as mitogens. Enhancement in lymphocyte proliferative response to mitogenic stimulation by PHA and PWM was seen in patients after 3 courses of chemotherapy + levamisole, whereas irradiation given after chemotherapy caused long-lasting depression in response to PHA (p = 0.039) and PWM (not significant). T-lymphocyte counts were also lower after irradiation than after chemoimmunotherapy (p = 0.007). Clinically, the 16 patients treated with radiation therapy after chemotherapy exhibited a higher recurrence rate than the 24 patients treated first by irradiation. Enhanced reactivity to tuberculin tests occurred generally in patients receiving a planned treatment including irradiation, chemotherapy (5-fluorouracil, doxorubicin, cyclophosphamide) and levamisole. Enhancement of reactivity was seen more often in patients who had not relapsed.","PeriodicalId":77655,"journal":{"name":"Acta radiologica.

The dependence of the quality parameters on the design of the clinical beams such as the incident electron energy, target and filter thicknesses, field size and depth in the phantom are analyzed in some detail using analytical and Monte Carlo techniques. It is shown that the mean attenuation coefficient of the beam for a standard field size of 10 cm X 10 cm is related very accurately to the mean stopping power ratio for ionizing chamber dosimetry but also approximately to the equilibrium absorbed dose in the beam for a given photon energy fluence. This means that accurate photon dosimetry can be performed without knowing the acceleration potential, target design or filter thickness for the beam in use. Furthermore, the mechanism behind beam hardening and softening in the phantom are quantitized and suitable quality parameters for the lepton contamination are identified. The latter allow a determination of the lepton contamination for correction of the stopping power ratio near the surface if the contamination is large.","PeriodicalId":77655,"journal":{"name":"Acta radiologica.

The experimental design is based on the assumption that impaired immune responsiveness, by other means than 90Sr, might increase the neoplastic response in exposed individuals, and thus reflect a protective function, if existing. Intercomparison is made of the tumour yield in mice exposed to different single doses of 90Sr and simultaneously subjected or not to long-term immune suppression by adult thymectomy (ATx) and/or antilymphocyteglobulin (ALG) treatment. Information on the general condition and responsiveness of the immune system, in the respective models, during tumour expectancy time, is essential for a conclusive evaluation of the results. To meet these demands the present paper reports on histopathologic alterations in immune organs and changes in white blood cell counts, induced by the different combinations of 90Sr, ATx and ALG treatment. The results confirm the prediction, that ATx + ALG is an efficient and, with respect to the purpose of the study, suitable treatment for additive long-term depression of the immune system in 90Sr irradiated mice, evidenced in particular by increased depletion of monomorphonuclear cells (MNC) in lymphoid organs and peripheral blood. Subsequent reports will deal with functional immune parameters.","PeriodicalId":77655,"journal":{"name":"Acta radiologica.
