Study on Reversibility of Genetic Toxicity of TDI in Mice
This article studied whether genetic toxicity of toluene diisocyanate was reversible. Kunming mice were exposed to TDI by respiratory tract for 14 days in 1/8LC50, 1/4LC50 and 1/2 LC50 dosage and then were feed normally for 14 days. The chromosomal aberrations and the content of RNA & DNA were detected by optical microscope and laser scanning confocal microscope. In 1/4LC50 and 1/2 LC50 group, chromosome aberration rate and the RNA /DNA ratio of TDI were higher than control group significantly (P<0.01). In addition there was no significant difference between 1/4LC50 and 1/2 LC50 (p> 0.05). The results showed that the damage of TDI on chromosomes and DNA was repairable, but can not be repaired completely.
