Evaluation of the Toxicity of Pradosia huberi Extract during the Preimplantation in Wistar Rats

Abstract EN

The treatment during the embryonic preimplantation phase of Wistar rats with the Pradosia huberi extract did not interfere with the water and feed consumption, as well as upon the body-weight gain.

However, it has expressed a decrease of the uterine implant number, followed by the preimplantation losses at all applied doses (1.22, 6.1, and 30.5 mg/kg), and the number of embryonic resorptions in the two highest doses (6.1 and 30.5 mg/kg).

After the organ weighing (hypophysis, ovaries, and uterus), only the relative weight of the hypophysis was raised at the different doses (1.22, 6.1, and 30.5 mg/kg).

It was concluded that the hydroalcoholic extract of Pradosia huberi compromises the reproductive ability during the embryonic preimplantation phase, suggesting a possible toxic effect upon the reproductive system of Wistar rats.
