Effects of licorice aqueous extract on morphological changes in the uterine inner annular layer. Example histological section of the uterine inner annular layer using HE staining under the light microscope at 200× objective. No discernible pathological changes were observed in the control group and the myometrial cells were slender with round nuclei, which was described as fusiform nucleated cells. The short rod-shaped cells with shorter nuclei were in contractile status, which was described as oval nucleated cells. The licorice aqueous extract downregulated the proportion of oval nucleated cells (contractile cells) in uterine inner annular layer.
