Objective To investigate the role of cerebellar dentate-interpositus (D-I) nuclei during acquisition of classical eyeblink conditioning in guinea pigs. Methods A 500 ms tone conditioned stimulus (CS) was paired with a 100 ms corneal oxygen-puff unconditioned stimulus (US) in a delay paradigm. Guinea pigs were trained daily to acquire the classically conditioned eyeblink responses. Micorinjections of Muscimol into bilateral cerebellar D-I nuclei were performed during the 4-6 day of training session. A high-resolution potentiometer was used to detect the eyeblink responses. Results The conditioned response (CR) rates of Muscimol-injected group on session 4-6 were significantly lower than their rates on session 3 (P1=0.005,P2=0.004,P3=0.010); Their rates on session 7 and 8 were as the same level as those without microinjection on session 4 and 5 (P1=0.061,P2=0.669). However, there was no significant difference on their amplitude and peak latency of unconditioned responses (URs) during the entire course of training (P1=0.926,P2=0.939). Conclusion The cerebellar D-I nucleus is actively involved in the neural circuitry of motor learning, which is essential for both acquisition and performance of the classically conditioned eyeblink responses.

Objective:Coherence analysis of the EEG is used to study the synchrony or coupling between cortical areas underlying the electrodes. However,the effects of intravenous anesthetics on EEG coherence have not been defined. Method: Forty patients were administered with intravenous thiopental (5mg/kg),propofol (2.5mg/kg ), ketamine(4mg/kg)or fentanyl(10?g/kg). The changes of coherences in total and in a given frequency band of the EEG(?.?.?.?) were measured with an AXON Systems Sentinel-4 Neurological monitor between two pair electrodes(Cz-F_7 vs Cz-F_8 and Cz-A_1 vs Cz-F_2). Result: The anesthetics had significantly different effects on the coherence by either increase or decrease. The variability of the coherences had no regular pattern,and no relationship to excitement or depression of the anesthetics and to potency of them. Conclusion:Each anesthetic above selectively depresses and excites generators of the EEG in quite different ways.

Objective To investigate the biophysical properties of mechanosensitive(MS) channels in cultured dorsal root ganglion neurons of neonatal rats. Methods MS channels current of cultured dorsal root ganglion neurons of neonatal rats were recorded using cell-attached and inside-out patch-clamp technique.The biophysical properties such as pressure response relationship,current voltage relationship,channel kinetics and ion selectivity were analyzed.Membrane stretch was achieved by the application of negative pressure(suction) to a patch-clamp electrode. Results One type of MS non-selective cation ion channels in the membrane patches tested in cultured dorsal root ganglion neurons of neonatal rats were recorded. Those channels were activated rapidly when suction was applied, and kept active during sustained application of negative pressure and quickly turned off when the suction was released.The MS channels exhibited a nearly linear current voltage relationship in the balance solution.The outward chord conductance was (96.2?3.6)pS (mV is between +40 mV and +60 mV) and the inward slope conductance was (62.5?0.4)pS (mV is between -60 mV and 0 mV). This kind of channels appeared to be outward rectifier.The average reversal potential was (-2.3?0.8)mV.The channel kinetics analysis indicated that suction could significantly increase the duration of short-openings and long-openings and decrease that of long-closings,with no effects on short-closings. Conclusion The results of this study could serve as a reference to the understanding of electric activity of DRG neurons.

The content of zinc and copper in the hair of 321 persons was detected by an atomic absorption spectropolarimeter. The subjects included young healthy group (35 men, 30 women), middle aged healthy group (72 men, 18 women), arteriosclerosis group (81 men, 20 women), cerebral embolism group (23 men, 8 women) and its control group (23 men, 8 women). The ratio of zinc to copper in the hair of the persons suffered from cerebral embolism was obviously higher than that of healthy controls. By comparing the function of the susceptible factors in cerebral embolism with Feisher's determination analysis method, diastolic pressure was found to be 75.02 percent, the ratio of zinc to copper 16.32 percent. The diagnostic coincidence was found to be above 82 percent.
