Worm Expulsion

In rats treated with compound 48/80 or histamine, worm expulsion was inhibited. Treatment with a histidine decarboxylase inhibitor accelerated worm expulsion. Treatment with compound 48/80 elevates histamine and histidine decarboxylase levels and reduces circulating reagin titres. These results show that histamine is not responsible for worm expulsion.Compounds such as isoprenaline and theophylline which increase cellular levels of cyclic 3′,5-AMP, prevented worm expulsion.It is concluded that the evidence that amines are involved in worm expulsion needs reassessing and that cellular release mechanisms in general may be affected by drugs thought to act solely on amine release. In particular, the release of effector substances from sensitized lymphocytes on contact with antigen may be affected by these treatments.The skilful technical assistance of Miss R. Keist and Miss I. Beeger is gratefully acknowledged. We thank Mr H. Berchtold, Biostatistisches Zentrum der Universität Zürich, for the statistical evaluation of the data.

Old Rats

α-Fluoromethylhistidine, a histidine decarboxylase inhibitor, induced a significant depletion in the hypothalamic, midbrain, and cortical brain histamine amounts in 12- and 3-month-old rats. In all three brain regions the most evident depletion occurred 2 h after treatment. In both groups of rats midbrain histamine levels returned to control values 6 h after treatment; however, hypothalamic histamine depletion was still significant and more evident in the old than in the young animals. Cortical brain histamine also remained significantly depleted in old rats, but returned to control values in young animals 6 h after α-fluoromethylhistidine treatment. These results suggest that old rats show a slower rate of new histamine synthesis in the cortex and hypothalamus. Regional brain histamine depletion was associated with a very significant decrease in plasma corticosterone levels, which indicates that brain histamine–corticosterone interactions do occur.
