    Notizen: Abstract Background: To minimize the side effects of treatment in childrenwith Hodgkin's disease (HD), chemotherapy was given without radiotherapy. Patients and methods: From 1975 to 1984, 21 patients with HD havinglymph nodes 〈 4 cm were treated with six MOPP courses. From 1984 to 1987,all children presenting with HD (n = 17) were given six ABVD courses.From 1987 to 1993 all children (n = 21) were treated with sixalternating ABVD and MOPP courses. Results: MOPP-treated children showed an event-free survival (EFS)of 91%, overall survival, 100%; ABVD-treated children had an EFSof 70%, overall survival, 94%; ABVD-MOPP-treated children hadan EFS of 91% and an overall survival of 91%. Two casesdeveloped a second malignancy. Toxicity was low. Conclusions: In children, ABVD-MOPP treatment gives a good survival,and toxicity is low. Radiotherapy is not needed to treat HD in children.

    Notizen: Summary The effect of the histamine liberator compound 48/80 on the rat superior cervical ganglia in vitro has been investigated. After incubation of the ganglia with compound 48/80: (1) ganglionic mast cells degranulate in the same manner as in other tissues; (2) cell bodies of the postganglionic neurons are not affected by compound 48/80; (3) there is evidence that ganglionic interneurons, the monoamine-containing cells are activated. The ultrastructural aspects of this process are characterized by degranulation of perikarya and accumulation of dense core vesicles in cell processes and in terminals adjacent to presynaptic membranes. These vesicles vary in size between 200–800 Å in diameter. They may represent storage sites of the neurotransmitter complexes that have undergone exocytosis. The results are discussed with special reference to models of exocytotic processes involving the adrenergic transmitter. It is concluded that monoamine-containing cells represent interneurons in sympathetic ganglia which inhibit ganglionic transmission and which are stimulated by low concentrations of compound 48/80 in vitro.
