Urine pH and urinary excretion rate of PSP. PSP was administered intravenously at 2.5 mg/kg (A, C) and 25 mg/kg (B, D). Control group is represented by open circles and white columns. SBECD group is represented by closed circles and black columns. SBECD (saline in control) was administered intravenously at 320 mg/kg before the infusion of PSP. Each point and column represents the mean ± S.D. of three rats from two separate experiments. *p < 0.05
