Jervine, a novel steroidal alkaloid from Veratrum nigrum L., exhibits both antitumor effect and potential toxicity. The aim of study was to characterize the pharmacokinetic behaviors and enterohepatic circu-lation of jervine in rats. A rapid and simple ultra-high performance liquid chromatography-tandem mass spectrometric method was developed and validated for quantification of jervine and alpinetin (internal standard) in rat plasma. After extraction from rat plasma by a simple protein-precipitation method, the analyte was separated on a C18 column (2.1 mm × 50 mm, 1.7μm) using water with 0.1%formic acid and acetonitrile as the mobile phase delivered at a flow rate of 0.4 mL/min. Jervine and alpinetin were determined in the positive mode with multiple reaction monitoring (MRM) of the ion transitions at m/z 426.3→108.8 and m/z 271.0→166.9, respectively. Molecular docking method was used to investigate the binding of jervine to p-glycoprotein and dehydroepiandrosterone sulfotransferase. The method was well validated within acceptance limits including specificity, matrix effect, recovery, precision, accuracy, and stability, and was successfully applied to the pharmacokinetic study of jervine after oral and intravenous administration to rats. Jervine presented a small volume of distribution, fast absorption, high oral bioavailability, and enterohepatic circulation. The enterohepatic circulation was first observed in veratrum alkaloids, and was further investigated by molecular docking studies, which was related to the binding of jervine to p-glycoprotein and dehydroepiandrosterone sulfotransferase. The pharmacokinetic properties and enterohepatic circulation of jervine in rats provided a significant basis for the drug-drug interaction and toxicity study in the future.

Journal of Zhejiang University. Medical sciences 2013;42(6):666-670
OBJECTIVETo prepare the poly(lactic-co-glycolic acid) (PLGA) microspheres and composite alginate-chitosan-PLGA microspheres containing superoxide dismutase (SOD) and to evaluate their SOD activities.
METHODSThe SOD-PLGA microspheres were prepared by W/O/W emulsification method, and the composite microspheres were prepared by two steps:alginate-chitosan microcapsules were first prepared by a modified emulsification and ion crosslinking method, and then they were further dispersed in PLGA to form the composite microspheres. The SOD concentration was determined by Coomassie method, its activity was measured by xanthine oxidase system.
RESULTSThe SOD activity was less sensitive to temperature and sensitive to pH, organic solvents, ultrasound and vigorous stir without iced bath. The entrapment efficiencies of SOD in PLGA (50:50) microspheres, PLGA (70:30) microspheres, alginate-chitosan microcapsules, the composite PLGA (50:50) microspheres and the composite PLGA (70:30) microspheres were 36.42%±1.81%, 66.18%±0.05%, 91.08%±1.28%, 87.30%±3.89% and 83.19%±3.48%, respectively. In vitro release tests demonstrated that the SOD activities in 50:50 composite microspheres were higher than that in the PLGA ones at 1 h, 8 h and 1 w.
CONCLUSIONThe composite alginate-chitosan-PLGA microspheres for SOD sustained release can significantly improve the protein entrapment efficiency and maintain its protein activity.

The activity of the NK cells in patients with preeclampsia was studied to investigate the pathogenesis of preeclampsia. By using MTT and 51Cr releasing technique, the proliferation and killing ability of the NK cells in maternal and umbilical blood from preeclampsia patients (n = 18) and normal third trimester pregnant women (n = 18) were detected. The NK-92 cell line was as the positive control. The results showed that the NK cell counts of umbilical blood in preeclampsia patients and normal third trimester pregnant women were significantly greater than those of maternal blood (both P<0.05). Compared with that in normal third trimester pregnant women, the proliferative ability of the NK cells in preeclampsia patients was apparently increased (P<0.05). Compared with that in maternal blood, the proliferative ability of the NK cells in umbilical blood from both preeclampsia patients and normal third trimester pregnant women was dramatically increased. The killing ability of the NK cells in preeclampsia patients was significantly higher than that in normal third trimester pregnant women (P <0.05). It was suggested that both number and function of the NK cells in preeclampsia women were increased, and that in umbilical blood was greater than that in maternal blood, speculating that the function of the NK cells may affect the maintenance of the maternal and fetal immune tolerance during pregnancy.
