[Ulinastatin attenuates lung injury in rats with hemorrhagic shock].

Objective: To investigate the effects of ulinastatin on lung injury in hemorrhagic shock rats.

Methods: Twenty-four normal SD rats were randomly divided into 3 groups (n=8), namely the control group, hemorrhagic shock group (group H) and ulinastatin group (group U). In group H and group U, blood was drawn from the femoral artery over a period of 10 min until a mean arterial pressure of 40 mmHg was obtained.

[Cerebral uptake and regional cerebral distribution of propofol under concentration equilibrium condition in the internal carotid artery and internal jugular vein in dogs].

Objective: To investigate the cerebral uptake and regional distribution of propofol when plasma propofol concentration reaches equilibrium in the internal carotid artery and internal jugular vein in dogs.

Methods: Eight male hybrid dogs aged 12-18 months weighing 10-12 kg were anesthetized with propofol at a single bolus (7 mg/kg) in 15 s followed by propofol infusion at a constant rate of 70 mg.kg(-1).
