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.
