TERATOGENIC EFFECT OF HERBICIDE GLIFONOX IN RATTUS NORVEGICUS, WISTAR STRAIN

Abstract

Teratogenic effect of herbicide glyphosate-Roundup, sold under the name Glifotox on Wistar rats was evaluated. The biological material was treated intraperitoneally with glyphosate at concentrations of 100, 125, and 150 mg/kg from gestation day nine. Hysterectomy was performed on day 18 of gestation, and the uterine horns where the embryos were located, in addition to recording the percentage of malformed embryos by modifying the method of Wilson were observed. The liver was removed and quantified by spectrophotometry with transaminase activity showed higher concentrations malformation rate and higher enzyme activity was 125 mg/kg, below is the average of 100 mg/kg and higher concentrations such as 150 mg/kg a large number of resorptions was obtained. It is concluded that glyphosate is toxic affecting the liver and liver enzymes involved in the formation of amino acids also produce delay in embryonic development.
