Objective To explore the effects of subchronic arsenic exposure through drinking water on glutamate-glutamine cycle in the brain of mice. Methods The female Kunming mice were exposed to arsenite ( iAsⅢ ) by drinking water at the levels of 25, 50 and 100 mg/L respectively for 6 consecutive weeks. The blood and brain were taken, the concentration of inorganic arsenic (iAs), monomethylarsenic acid (MMA), dimethylarsenic acid (DMA) and the activity of glutamine synthetase (GS), phosphate activated glutaminase (PAG), superoxide dimutase (SOD) and the concentrations of glutamate (Glu), lipidperoxide(LPO) were determined. Results The concentrations of iAs, MMA and DMA in the blood and brains increased as the iAsⅢ concentrations in drinking water increased. The activity of GS, PAG and the concentrations of Glu in the arsenic exposed mice increased compared with the control. The activity of GS in 50 mg/L group, the activity of PAG in 25 and 50 mg/L groups, the concentration of Glu in 100 mg/L group showed a significant difference compared with the control. The activity of PAG in 25 mg/L group was significantly higher than that in 100 mg/L group. The activity of SOD in exposed groups was higher than that in the control, the concentration of LPO in exposed groups did not show a significant difference compared with the control. Conclusion Arsenic can enter the brain and organic arsenic is dominant both in the blood and brain, however, the composition of arsenic speciation is different in the blood and brain. DMA, as a main arsenide, distributed in the brain. Arsenic exposure can change the activity of GS and PAG which can influence the concentration of Glu. Moreover, arsenic exposure can increase the superoxide anion and make the activity of SOD increase compensatively.

AIM:To select an optiomal formulation of liposome entrapped alkanin prepared with ethanol injection in the combination of orthogonal design and central composite design/Response surface method.METHODS:Five influencing factors,including ratio of alkanin to liposome and soyabean lecithin to cholesterol,volume ratio of ethanol phase to water phase,soybean concentration and mannitol concentration were chosen as indices by orthogonal design.Then the method utilized the central composite design,which fitted multivariate linear and second/third order nonlinear regression equation,to find out the optimal formulation.RESULTS:Third order regression equation gained made the good prediction about entrapment(85.4%)and alkanin load(5.16%),and exhibited no significant difference between theoretic value and measured value.CONCLUSION:The combination of orthogonal design with central composite design is a feasible and convenient method to optimize the prescription of alkanin-liposome.

This study aimed to optimize the ultrasonic extraction of gardenia oils from Gardenia jasminoides Ellis.by response surface analysis methodology (RSM).The duration of extraction,ratio of liquid to materials and extracting times were selected as impact factors based on single-factor experiment.RSM was adopted to learn the effects of the three factors on the extraction rate of Gardenia oil from Gardeniajasminoides Ellis.As a result,it was found that the duration of extraction was 28.7 min,while the ratio of liquid to materials was 11.62:1,and the number of extracting times were 3.36.Under this extracting condition,the average extraction rate of the oil was 13.5% according to three validation experiments,fitting the predicted value well.In conclusion,it was demonstrated that the ultrasonic extraction method effectively improved the extraction rate of gardenia oil,providing a certain basis for the development and utilization of gardenia oil.
