TH and infection: In the kidney, serious granular and vacuolar degeneration and cell necrosis were observed in the infected-untreated group (Figure 1N); mild granular and vacuolar degeneration were observed in the ShiYingZi-PM group (Figure 1O), ShiYingZi-TH group (Figure 1Q), and positive control groups (Figure 1P, monensin; Figure 1R, sulfachloropyrazine sodium); more severe inflammatory cell infiltration was observed in the sulfachloropyrazine sodium group (Figure 1R) than that in the ShiYingZi-TH group (Figure 1Q); and without infection, the kidney showed a normal structure (Figure 1I).
