Histological study of the liver and lung tissues of pyrethroid exposed mice

Cypermethrin, a type II pyrethroid considered to be environmentally safe, is one of the most widely used pyrethroid insecticide. But the possible health hazards of these pyrethroids have been ignored. Cypermethrin may become an air pollutant and adversely affect the health. The present work was aimed to investigate the possible health effects of cypermethrin on the lung and liver tissues caused by inhalation. The study was performed on 16 mature Swiss albino mice. While 4 of them were used as control, the remaining 12 were divided into three groups (of 4 mice each) exposed to 0.5% dilution of cypermethrin in an…
