Description:
Triethyltin (TET) and trimethyltin (TMT) are neurotoxic organotin compounds which produce different patterns of toxicity in adult animals. Exposure to TET produces behavioral toxicity (decreased motor activity, grip strength, operant response rate and startle response amplitude) which reflects impaired neuromotor function. These deficits are consistent with the reported myelin vacuolation and cerebral edema produced by TET, and with its direct effects on muscle. Exposure to TMT produces both hyperactivity and impaired learning and performance. These impairments are consistent with reported neuronal cell death produced by TMT, particularly in limbic system structures. While the behavioral deficits produced by repeated exposure to TET are reversible when dosing is terminated, the behavioral impairment produced by a single exposure TMT appears to be irreversible.
