Abstract
The perinatal period is very critical as the embryo or the new born is more susceptible to Cd toxicity. This study was done to measure Cd levels in brain tissue of F1 and F2 generation mice whose mothers were exposed to Cd during lactation or during the entire period of gestation and lactation and also to investigate whether quercetin could modulate this effect. Dams were exposed to cadmium during lactation and during the entire perinatal period. F1 and F2 generations were reared till 100 days of age. After being sacrificed, their brains were extracted, and cadmium levels were estimated using Atomic absorption spectrophotometer. It was found that Cd levels in brain tissue were significantly higher in the F1 generation when animals were exposed in lactation. There was slight increase in Cd in brain tissue of animals exposed during gestation as well as lactation, but the change was not statistically significant. Quercetin reduced the Cd levels significantly in a dose dependent manner in lactation group. In the other two groups it reduced the Cd levels even lower than the controls. This study shows that Cd is passed on to the next generation more efficiently when exposed during lactation. Lesser transmission is seen when exposure is during gestation followed by lactation. Quercetin effectively reduces Cd levels in brain tissue irrespective of the type of exposure.
