ABSTRACT: To investigate the protective effects of BPI on the vital organ function after endotoxic shock in rats, and to provide experimental evidence for further clinical studies.
12.5 mg/kg of E. coli 026:B6 LPS were bolus injected via i.a. to reproduce endotoxic shock. Immediately after injection of LPS, 5 mg/kg of BPI or equal volume of physiological saline were bolus injected via i.a.
The survival time of shocked animals was prolonged in the BPI group, 24 h survival rate was higher than that in the saline group. The values of mean arterial pressure, left intraventricular systolic pressure, isovolemic ventricular pressure, and dp/dtmax in the BPI group were markedly higher than those in the saline group. The plasma glutamic-pyruvic transaminase and urea nitrogen levels were obviously lower than those in the saline group. The plasma endotoxin and TNF levels in the BPI group were significantly lower than those in the saline group.
BPI has good protective effects on cardiac, hepatic, and renal function in endotoxic shock in rats, indicating that BPI might be useful in clinic treatment of sepsis/septic shock.
