5、hown to inhibit the intracellularactivation of caspase-like proteases. The injection of Z-VAD(OMe)-FMK suppresses the caspase-3 activity inlung tissues, and significantly decreases the number of terminal dUTP nick-end labeling-positive cells 1. Z-VAD(OMe)-FMK is administered intraperitoneally at 1 h

6、our before and 6 hours after SAH. Expression ofcaspase-3 and positive TUNEL is examined as markers for apoptosis. Z-VAD(OMe)-FMK suppressesTUNEL and caspase-3 staining in endothelial cells, decreases caspase-3 activation, reduces BBBpermeability, relieves vasospasm, abolishes brain edema, and improv

7、es neurological outcome 2. Z-VAD(OMe)-FMK is a cell-permeable caspase inhibitor, efficiently blocks cell death induced by SMNdeficiency 3.体内研究 The survival rate of mice is prolonged significantly by the injection of Z-VAD(OMe)-FMK. All mice succumbedto LPS within 30 hours. By contrast, the mice trea

ThedsRNA products are ethanol precipitated and annealed by incubation at 65C for 30 min and then slowlyallowed to cool at

11、 room temperature. The annealed dsRNA products are analyzed on a 1% agaorse gel toensure the majority of dsRNA existed as a single band. The dsRNA (2 g) and/or plasmid DNAs (2 g) areintroduced into cells by using Cellfectin. Caspase inhibition is achieved by using 50 M of Z-VAD(OMe)-FMKin the cultur

Mice are injected with 30 mg/kg LPSfrom E. co

13、li serotype O111:B4 through the tail vein. A single intravenous injection of Z-VAD(OMe)-FMK (0.25mg) is made 15 minutes before LPS injection, followed by three intravenous injections of Z-VAD(OMe)-FMK(0.1 mg each) per hour. Control mice are injected with the same volume of 1% DMSO in sterile saline.

14、Rats 2Male Sprague-Dawley rats weighing 300 to 350 g are anesthetized with -chloralose (40 mg/kg IP) andurethane (400 mg/kg IP). Animals are intubated, and respiration is maintained with a small animal respirator.Rectal temperature is maintained at 370.5C with a heating pad. The left external caroti

Sham-operated rats underwent the sameprocedures except that the suture is withdrawn after resistance is felt. Z-VAD

16、(OMe)-FMK (50 M per 0.3 mL)is injected intraperitoneally at 1 hour before and 6 hours after SAH induction. In vehicle group, ratsunderwent SAH induction and are treated with the same volume of vehicle (DMSO diluted in physiologicalbuffer solution). No treatment is applied in sham-operated animals.MC
