Lambda Cyhalothrin (LCT) is a type II synthetic pyrethroid widely used in agriculture, home pest control and protection of food stuff. Here, we evaluated its toxicity on biochemical parameters (Total protein, Acetyl cholinesterase, RNA and DNA) and liver histological alteration in mice after 24 h of oral administration @ 25, 50 and 75% of LD50 i.e.; 26.49 mg/kg/body wt. Distilled water (DW) and Cyclophosphamide (CP @ 40 mg/kg/body wt.) were used as negative and positive control; respectively. LCT treated mice showed significant decrease in total protein (P < 0.01), acetyl cholinesterase (P < 0.001) and DNA (P < 0.001) in a dose dependent manner. On the contrary, RNA content showed significant increase (P < 0.01) at 50% of LD50 of LCT. Histological observations of the mice liver showed vascular congestion and hepatocyte degeneration with 6.63 mg/kg/body wt. of LCT; and accumulation of RBCs with sinusoid degeneration and wide necrotic area with pyknosis with 13.25 and 19.88 mg/kg/body wt., respectively. The results demonstrated LCT induced biochemical changes and hepatotoxicity in female mice.
