    Description / Table of Contents: Zusammenfassung Spezielle Behandlungsmaßnahmen sind 1. Stoßartig Steroidhormone, 2. Antithyreoidale Substanzen, 3. Radiojod, 4. Strumaresektion. Die ersten beiden sind passagere Verfahren und ergänzen die definitiven nuklearmedizinischen und operativen Behandlungsmaßnahmen. Differentialtherapeutische Erwägungen knüpfen sich an Lebensalter und Kropfgröße. Für ca. 60 % aller Fälle ist die Radiojodtherapie optimal, je größer eine hyperthyreotische Struma, desto eher ist die Operation indiziert. Detaillierte Gesichtspunkte werden anhand von 3580 eigenen Fällen von Hyperthyreose erörtert.
    Notes: Summary Special procedures are: (1) Short-term treatment with steroid hormones; (2) antithyroid substances; (3) radioactive iodine; (4) operation. The first two methods are complementary to the definitive procedures of isotope and surgical therapy. The indications conform to the age of the patient and the size of the goiter. The treatment of choice in 60 % of all cases is radioactive iodine; 20–25 % are treated with antithyroid substances only for several years. The remaining cases, complicated by goiters of size II and more, should be handled surgically. Discussion based on personal experience with 3580 cases over 20 years).

    Notes: Abstract Polysaccharide K (PSK) is a biological response modifier used for adjuvant immunotherapy of malignant diseases. We studied the potential applicability of PSK for preventing tumor progression using an experimental model of murine lymphoma. Mice inoculated with the radiation leukemia virus (RadLV) develop thymic lymphomas after a latency of 3–6 months. However, 2 weeks after virus inoculation, prelymphoma cells can already be detected in the thymus. We found that PSK treatment induced hyperresponsiveness to concanavalin A and heightened production of interleukin-2 (IL-2) and IL-4 in spleen cells of both control and prelymphoma mice. The response was transient and was accompanied with a dominant usage of T cells expressing Vβ8, but other T cell subsets were also stimulated by PSK. T lymphoma cells expressing Vβ8.2 underwent apoptosis when incubated with PSK. Treatment of RadLV-inoculated mice with PSK delayed the onset of overt lymphoma (and mortality) but could not protect the mice from the disease. Combined treatment with PSK and a RadLV-specific immunotoxin prevented synergistically the progression of the prelymphoma cells to frank lymphoma. The results suggest that PSK contains a superantigen-like component that selectively activates Vβ8+ T cells. Its administration prelymphoma mice interfered with the process of lymphoma progression.
