Fig. 4From: Berberine exerts a protective effect on rats with polycystic ovary syndrome by inhibiting the inflammatory response and cell apoptosisThe effects of BBR on cell apoptosis in PCOS rats. a Apoptotic cells were observed by using the TUNEL assay kit. The positive apoptotic cell nuclei were dark brown in color, and the non-apoptotic cell nuclei were blue in color. b The apoptosis of interest (AOI) was calculated. * P < 0.05, compared with the control group. # P < 0.05, compared with the PCOS-ND group. $ P < 0.05, compared with the PCOS-HFD groupBack to article page
