Aim To investigate the pharmacokinetics of ginsenoside Re(G-Re)in chinese healthy *** An open-label,randomized and crossover clinical trials recruited 16 healthy volunteers were carried out for single-dose(100 and 200mg)and multiple-doses(100mg×2/d×7d) administration *** concentrations of G-Re and its metabolites in human plasma and urine were determined using HPLC-MS/MS *** Pharmacokinetic parameters were determined from plasma G-Re *** single-dose administration,there was no statistical difference of Tbetween 100 and 200mg doses,and the accumulative excretion rate of G-Re from urine after 24. administration were(0.0036±0.0021)% and(0.0017±0.0011)% for 100 and 200mg doses,*** multiple-doses administration,the values of Cand AUCof d7 were the double to those of d1,and no statistically significant difference was seen in Tand ln Cbut was seen in *** accumulative excretion rate of G-Re from urine after d7 administration were(0.004.±0.0025)%.Conclusion The present studies indicated that G-Re after orally in single-dose or multiple-doses administration is minimally absorbed and excretion from urine in *** are not significant differences of the pharmacokinetic parameters between single-dose and multiple-doses study except for AUC.

＜正＞Cyclopeptides and their derivatives continue to hold the attention of synthetic chemists and biologist alike. Besides their bioactivity, the rigid conformation that allows them to be used in the study and mimicry of protein folding and to present diverse functionality in a defined and predicable manner is another attractive feature of the cyclopeptides. Here we present the synthesis of two disulfide cyclopeptides which contain four （lR,3S）-3-aminocyclohex-

Corss-modal learning of animals using "BatEars"

中国神经科学学会第四次会员代表大会暨第八届全国学术会议

＜正＞Objective Cross-modal learning is crucial for daily activities and survival for both animals and *** recent results of fMRI study showed that the visual cortex was activated as well as the hippocampal system with the "BatEars" sound after a 2-week training *** further investigate the neural mechanisms underlying the cross-modal learning at the neuronal levels,animal model replicating the human studies is ***（1） Cats will be trained to use the electronic "BatEars" to navigate themselves in three types of mazes.（2） Neuronal activities of the auditory and visual cortices,and the entorhinal and/or perirhinal cortices in the hippocampal system will be simultaneously recorded while the animal is trained to use the "BatEars".Results The animal with deprived vision could learn to use the signals from the "BatEars" to navigate within circled maze.
