Effects of rapamycin or chloroquine on autophagic activity and EG-induced CaOx crystals depositions in rat kidneys. (A) Quantitative changes in autophagic vacuoles under TEM in kidney sections from indicated rats. The red arrows indicate autophagic vacuoles. Scale bar: 1 µm. (B) The expressions of Beclin1 and SQSTM1 in kidney sections from indicated rats were detected by immunohistochemical staining and quantified using Image Pro Plus software. (magnification 200×) (C) Photomicrographs of kidney sections from indicated rats were obtained under dark field illumination with polarized light. Retained crystals exhibit strong birefringence (magnification 200×). The sizes of the areas of crystal deposition per field were estimated and quantified using ImageJ software. *P < 0.05, **P < 0.01 and ***P < 0.001.
