Abstract:
Objective To probe whether the preinduced adult animal hepatocytes (AHH) by phenobarbital sodium (PBS) in vivo could boost the metabolic activity of bilirubin in vitro for seeking the optimal biomaterial for the extracorporeal bioartificial liver support system (EBLSS). Methods Twelve adult male rats with 34g mean weight were randomly divided into preinduce group and control group, the rats of the preinduce group were intraperitoneal injected daily with 45mg/kg PBS for 5 days, while the control group with normal sodium. 0.5g wet weight liver was taken from every rat after 24 hours of last administer, the suspensions were made by mixing six wet weight livers in two groups and put in the cultivate board of 96 apertures, 30ul per aperture, then 50?l jaundice serum and 20?l culture fluid were added into every aperture, which were statically cultured in the incubaton of humidity 95% at 37℃, 5% CO2 for 3 hours, and then revolved, the metabolic activity of bilirubins were determined by Beckmann auto-analyzer. Results The total bilirubins and indirect bilirubins fell 60%, 71.42% respectively in the preinduced group, and 34.78%, 54.87% in the control group (P0.05, t=1.571). There were no obvious changes in direct bilirubins in two groups. Conclusions The preinduced AHH by PBS in vivo can boost the metabolic activity of bilirubin in vitro, it may be the optimal biomaterial for EBLSS.
