title: The interaction between anthelmintic drugs and histamine in Ascaris suum.
abstract: 1 Piperazine reduced the histamine content of Ascaris suum, yet it greatly increased the uptake of histamine from the surrounding medium, the neuromuscular structures of the nematode preferentially increasing in amount. 2 Bephenium reduced the histamine content of Ascaris and the uptake of histamine from the surrounding medium. However, the relative amount in the neuromuscular structures increased. 3 The flaccid paralysing action of piperazine may thus involve increased histamine absorption whereas the spastic paralysing action of bephenium may be independent of histamine.
