Striated ducts of the sublingual gland. a SHAM group; b OVX group; c OVX + E2 group; d OVX + iCR group. In picture a, the mitochondria were arranged in the plasma membrane infoldings and integral with its structure. In contrast, the plasma membrane infoldings had been lost, and many mitochondria were damaged, with a double membrane structure and crest lesions in b. Mitochondrial damage was rarely found, and plasma membrane infoldings were clearly visible in c. The mitochondria were intact in d, but they appeared bigger than in the other treatment groups. White arrows indicate mitochondria. White arrow heads indicate the plasma membrane infoldings. Bars 1 μm
