The effects of intraperitoneal administered tanshinone IIA sulfonate (TIIAS) on motor performance of normal rats in the rotarod test. Compared with the baseline response, intraperitoneal administration of TIIAS (2, 10, or 50 mg/kg) for 10 days did not affect motor performance. The results were expressed as a percentage of each rat’s own baseline value. TIIAS, tanshinone IIA sulfonate.
