Compared with control cells, cell viability is significantlydecreased in SH-SY5Y cells treated with thrombin.

9、ystem, is lower for the Baicalin treated groups than for the ischemia-reperfusion (IR)+salinegroup. Compared with the sham group, malondialdehyde (MDA) content is only slightly up-regulated and the SODactivity is only slightly down-regulated in rats treated with 10 and 100 mg/kg Baicalin, indicating

14、IR+Baicalin (1 mg/kg) group; (iv) IR+Baicalin (10 mg/kg) group; and (v) IR+Baicalin(100 mg/kg) group. Renal IRI is induced by clamping the left renal artery for 45 min plus a right nephrectomy. Ratsare anesthetized through an intraperitoneal injection of pentobarbital sodium (40 mg/kg body weight).
15、After amedian abdominal incision, the left renal arteries are clamped for 45 min with serrefine. After clamp removal,adequate restoration of blood flow is checked before abdominal closure. The right kidney is then removed. Sham-operated animals underwent the same surgical procedure without clamping1
