As shown in Figure 1, real-time RT-PCR analysis showed that the expression of LIF in the endometrium increased at late diestrus and proestrus phases during the estrous cycle (linear effect of day, p<0.05), while the expression of LIFR did not change during the cycle.

Smears were scored as follows: proestrus (P) contained primarily nucleated epithelial cells with no or few cornified cells, estrus (E) consisted of mostly cornified cells, metestrus (M) contained epithelial cells with leucocyte attacks, and diestrus (D) consisted of few cells that were leucocytes with some rounded or cornified epithelial cells.
Our previous study confirmed a significant lengthening of the estrous cycle and the diestrus phase, and an increase in the progesterone concentration in female rats treated with dill extracts, but the stereological study did not reveal any changes in the volumes of ovaries, and the primary, secondary, and graafian follicles (3).
