Figure 2. EG- and ractopamine-induced crystal deposition in the Malpighian tubules of Drosophila. (A) The images show representative polarized microscopy for the flies with 0.5% EG- and 10 ppb ractopamine-induced crystal formation in Malpighian tubules. (B) Rates of crystal formation in control, 0.5% EG-, and 10 ppb ractopamine-treated Drosophila (n ≅ 150 for each group). **P < 0.001, *P < 0.05, compared to the control group
