Y. Tuncok et al., PREVENTION OF ORAL DICHLORVOS TOXICITY BY DIFFERENT ACTIVATED-CHARCOAL PRODUCTS IN MICE, Annals of emergency medicine, 25(3), 1995, pp. 353-355
Study objective: To determine whether immediate treatment with oral ac
tivated charcoal (AC) products of differing surface areas prevents cli
nical toxicity of a lethal oral dose of dichlorvos in mice. Design: An
in vivo, prospective, randomized, placebo-controlled study using 75 m
ale albino mice. Interventions: Fasting mice were administered 57.5 mg
/kg of a 0.55% dichlorvos solution via feeding tube. One minute later,
groups of 15 mice each received 1 or 2 g/kg of Actidose-Aqua(R) AC or
1 or 2 g/kg of Sigma(R) AC or sterile water by feeding tube. In this
way, all mice received 15 mL/kg of an AC suspension or sterile water.
The animals were observed for 24 hours for seizures or death. Results:
In all treatment groups, mice were found to have significantly fewer
seizures and deaths (P<.05) than the control group when compared by ch
i2 and Fisher's exact tests. No statistical difference was found betwe
en the death and seizure rates when treatment groups were compared wit
h each other. The group sizes were too small, however, to rule out sig
nificant type II error (beta > .2). Conclusion: In this in vivo mouse
model, all AC products tested decreased the incidence of seizures and
death. Further studies should be done to investigate the clinical effe
cts of AC products with different surface areas.
