Efeito do extrato etanólico da Simarouba versicolor sobre os parâmetros reprodutivos de ratas / Effect of Simarouba vesrsicolor's ethanolic extract on the reproductive parameters of rats

ABSTRACT

The objective of this study was to evaluate the effect of the ethanol extract of Simarouba versicolor on reproductive parameters of Wistar rats (Rattus norvegicus) implantation index (%), resorption index (%), pre-implant loss, post-implant loss of the parents. pregnancy, the rats with approximately 90 days, weighing 160 to 250 g were divided into 4 groups (n=8), Control, Sv-EtOH 10, 20, 40mg/kg. The formulas used to evaluate reproductive parameters were following IMPLEMENTATION INDEX = (number of implantations / number of corpus luteum)x100; REABSORPTION INDEX = (no resorption*/ no implants) x100* no resorptions = (no implants)-(nofetuses); PRE-IMPLANT LOSSES = (No. of corpus luteum - No. of implants / No. of corpus luteum) x100; POSTIMPLANT LOSSES = (number of implants - number of natives / number of implants) x100. In the analysis of the implantation index, resorption, pre-implant loss and post-implantation loss were not significant when compared to the control. These results indicate the absence of maternal toxicity for the investigated doses during the period of pre-implantation, implantation and full term pregnancy. However, further studies with different doses and concentrations of Simarouba versicolor extract will be necessary in the gestational period.
