title: Biochemical, hematological and histological parameters induced by cypermetherin toxicity in domestic rabbits.
abstract: Cypermetherin is widely used in Algeria; this insecticide belongs to the group of pyrethroids classified by the World Health Organization as moderately harmful class II (WHO, 2005). This study was conducted to search the effect of non lethal dose on biochemical parameters, hematological and histological parts of the organs. Male of domestic rabbits Oryctolagus cuniculus (1 kg) received per week and per gavage 1/10 LD50 of Cypermetherin (ARRIVO 25%, active substance of Cypermetherin 250 g/l). blood was collected 72 hours after the treatment. Enzyme activities were assayed in the plasma samples for Glutamate oxalo acetate transaminase (GOT), Glutamate pyruvate transaminase (GPT), Alcaline phosphatase (AlcP), creatinine (Crea) and glucose. Red blood (RBC) cells and white blood cells (WBC) were calculated too. The results indicated a significant increase in transaminases GOT and GPT, and AlcP explain a high energy generating product and dysfunction of the liver. A decline in Crea, Hb, RBC and WBC which is related to the immunity, this is probably due to cell lyses explain the effect of Cypermetherin on erythropoeisis. Histological examination confirmed the biochemical tests by the observation of inflammatory infiltrate and perilobular fibrosis. In conclusion, Cypermetherin with used dose affects biochemical, hematological and histological parameters of the rabbits.
