Figure 3.The schematic representation of brief experimental schedule including modeling and treatment. After acclimatization, 10 rats were randomly assigned to the Control group and intravenously injected with saline (75 mg/kg). Meanwhile, other rats were intravenously injected with PAN (75 mg/kg) to establish NS model on day 0. In the subsequent fifteen days, they were orally administered distilled water, YBD or CsA respectively.
