METHODS:The study was performed with 30 male rats divided into three groups:a sham group,an obstructive jaundice group,and an obstructive jaundice plus honey group. At the end of the study period,the animals were sacrificed,and levels of nitric oxide(NO) ,and NO synthase(NOS) activities were measured in liver tissues,and levels of adenosine deaminase(ADA) and alanine transaminase(ALT) activities were measured in serum. RESULTS:Blood ALT and ADA activities were significantly elevated in the jaundice group as compared to those of the sham group. In the obstructive jaundice plus honey group,blood ALT and ADA activities were significantly decreased as compared to those of the jaundice group. In erythrocytes and liver tissues,NO levels were found to be significantly higher in the obstructive jaundice plus honey group compared to those of the sham group. Additionally,NO levels were found to be significantly higher in liver tissues from the animals in the obstructive jaundice plus honey group than those of the jaundice group.CONCLUSION:Honey was found to be beneficial in the prevention of hepatic damage due to obstruction of the common bile duct.展开更多

This control system makes use of the amplitude enhancement of alpha-wave blocking in electroencephalogram(EEG) when eyes close for more than 1 s to constitute a BCI for the switch control of wheelchair movements. The system was formed by BCI control panel, data acquisition, signal processing unit and interface control circuit. Eight volunteers participated in the wheelchair control experiments according to the preset routes. The experimental results show that the mean success control rate of all the subjects was 81.3%, with the highest reaching 93.7%. When one subject's triggering time was 2.8 s, i.e., the flashing time of each cycle light was 2.8 s, the average information transfer rate was 8.10 bit/min, with the highest reaching 12.54 bit/min.展开更多
