 This study investigated the effects of Dialythrin, a commonly used pyrethroid insecticide, on the liver and kidneys of pregnant mice. It also looked at its potential teratogenic effects on developing fetuses. The results showed that Dialythrin caused significant damage to both organs, including necrosis and hydropic degeneration of the liver and infiltration of inflammatory cells and fibrosis in the portal area of the liver. In addition, it caused premature births and failed fetal development in the fetuses. These findings suggest that Dialythrin should be avoided during pregnancy due to its potential harmful effects on the mother's organ systems and the unborn child. This article was authored by D.C.
