摘要: Abstract The aim of this study was to investigate whether Toxocara canis infection in guinea pigs provokes changes ileum responsiveness histamine. Ileum segments from control and T. -infected groups were placed at isometric conditions submitted various doses No observed between controls days 3, 6 12 after infection. However, 18 24 infection, there a significant increase histamine group. Pre-incubation with 1 mg ml −1 disodium cromoglycate (DSCG) prevented the increased did not affect contractility non-infected animals. These results indicate that develop intestinal DSCG prevents alterations smooth-muscle contractility.
