Figure 1. (IMAGE) Maximum Academic Press Caption (a) Microphotography, (b) crystal numbers of urine and the (c) frozen kidney sections. Urine was collected after the mice gavaged with AT, CH, CT, EG, ET, EC or ECT for 3 d. Frozen kidney sections of the mice gavaged with CT were observed under polarized microscope, the red arrows indicate the crystals induced by the treatment of CT. The crystal numbers in different groups were about 432, 456, 2,336, 2,984, 952, 904, 2,080, 3,928 C μL−1, respectively. Vertical bars on data in the columnar graph represented standard deviation; values with different letters are significantly different at p < 0.05.
