| 2 | Electrophysiological research of synapse formation from beginning to maturity显示文摘The development of synapses is an important question in neurobiology. We employ patchclamp technique to record MEPCs and EPCs of myoballs in Xenopus cell culture. The rate of EPC/MEPC is related with synapses maturation. Accordingly, we define the mature synapses as those whose rate of presynaptic membrane’s EPC to MEPC is more than 8. The process of maturation needs about 2-5 h after neurites contact with myoballs. We divide the development of synapses into three stages: young, developing and mature. The neurotransmitters stack gradually and increase by hundreds of times along with young synapses growing into maturity. So the process of synapses maturation should include presynaptic membrane specialization, postsynaptic membrane specialization and neurotransmitters stack. | XIE Zuoping and ZHENG Yufang State Key Laboratory of Biomembrane and Membrane Biotechnique Department of Biological Sciences and Biotechnology, Tsinghua University, Beijing 100084, China | 1998 | Chinese Science Bulletin1998，43，1： | 0 |
| 3 | Effects of Maca Extract on Endurance and Blood Antioxidant Enzyme Activity of Rats显示文摘[Objectives] The aim was to investigate the effects of maca extract on endurance and blood antioxidative enzyme activity of rats.[Methods]The Wistar rats treated with/without maca extract( 8. 0,16. 0,and 32. 0 g/kg) were given with free access to circulating water.The administration was conducted for 15 consecutive d. On the 16 th d,the endurance and blood malondialdehyde( MDA),superoxide dismutase( SOD) and glutathione peroxidase( GSH-Px) levels of the rats were determined. [Results] Compared with those of the rats without maca extract treatment,the swimming time before sinking of the rats administered with 8. 0,16. 0,and 32. 0 g/kg of maca extract was increased by 34. 38%,84. 25% and 126. 07%( P < 0. 01),the total swimming time was increased by 37. 42%,47. 03% and 107. 24%( P <0. 01),the times of sinking was reduced by 17. 65%,33. 28% and 55. 50%( P < 0. 05,P < 0. 01),the blood MDA level was reduced by 34.63%,54. 13% and 63. 73%( P < 0. 01),the blood SOD activity was increased by 67. 78%,108. 25% and 154. 49%( P < 0. 01),and the blood GSH-Px level was increased by 48. 57%,110. 28% and 154. 86%( P < 0. 01). [Conclusions]Maca extract has the functions of resisting fatigue and enhancing athletic,and the mechanisms are related to the reduction of blood MDA level and the increase of blood SOD and GSH-Px activity. | Zuoping LI Farong YU Mingren XIE | 2018 | Medicinal Plant2018，9，4： | 0 |
| 4 | Effects of Noise Pollution on Functions of the Liver and Kidney of Rats显示文摘To study the effects of noise pollution on the functions of the liver and kidney of rats,a total of 40 male SPF Wistar rats were randomly divided into a control group and three experimental groups. The rats in the experimental groups were respectively stimulated with 38,55 and 70 dB noise for 15 days,and the levels of blood components were determined by an automatic biochemical analyzer. The results showed that in comparison with the control group,the level of the blood glucose in the experimental groups increased by 23. 53%,52. 94% and 88. 24%,respectively,and the differences were statistically significant( P < 0. 01). The levels of triglyceride in the blood rose by 20. 83%,38. 54% and 79. 68%,respectively,and the differences were also statistically significant( P < 0. 01). The level of globulin in the blood increased by 16. 49%,21. 13% and 51. 78%,and the level of albumin in the blood rose by 9. 51%,12. 67% and 17. 89%,respectively. The level of total bilirubin in the blood increased by 27. 04%,41. 63% and 73. 67%,respectively,and the differences were statistically significant( P < 0. 01). The level of creatinine in the blood rose by 9. 72%,10. 21% and 20. 99%,respectively. The level of amylase in the blood reduced by 6. 6%,13. 05% and 23. 89%,respectively. The level of creatine kinase in the blood decreased by 19. 81%,27. 37% and 36. 81%,respectively,and the level of urea in the blood reduced by 11. 19%,12. 77% and19. 26%,respectively. The results revealed that noise pollution could significantly affect the levels of blood components and the functions of the liver and kidney of rats. | Yu Farong Yu Xin Li Zuoping Lian Xiuzhen Xie Mingren Li Denglou | 2018 | Meteorological and Environmental Research2018，9，4： | 0 |
| 5 | Inducement of Sechenov inhibition by EtOH and NA in the Bufo toad显示文摘Central inhibition, discovered by Sechenov in 1862, suggests that electrically stimulating the forebrain or medulla oblongata in frog generally suppresses reflexes. However, the underlying molecular mechanisms are still unclear. Using ethanol (EtOH), noradrenalin (NA), and other neurotransmitters in thalamic preparations, Sechenov inhibition was stimulated in Bufo toads in this study. The result showed that, similar to Sechenov inhibition, the acute application of EtOH or NA excited the thalamus and prolonged the latency of withdrawal reflex. Our study evidences the involvement of α-adrenoceptors in such central inhibition, and explains the role of acute EtOH application in the in- duction of reflex inhibition. | LI RuXin JIA ShanShan LI YingZi CAO Yin CHENG XiuZhen XIE ZuoPing | 2008 | Chinese Science Bulletin2008，53，8： | 0 |
