英文摘要 | AIM: To study the effects of pentobarbital (PB) on acutely dissociated rat sacral dorsal commissural neurons (SDCN). METHODS: Nystatin-perforated patch clamp recording was used. RESULTS: (1) At a holding potential of - 40 mV, PB induced inward Cl- current (I-PB) in a concentration-dependent manner with a EC50 (95 % confidence limits) of 416 (385 - 477) mu mol.L-1 and a Hill coefficient of 1.08. (2) Picrotoxin reversibly blocked I-PB (3) The reversal potential of I-PB was close to the Cl- equilibrium potential. (4) PB enhanced GABA-induced Cl- influx (I-GABA) In the presence of PB 30 mu mol.L-1, the EC50 (95 % confidence limits) of I-GABA decreased from 6.9 (5.4-8.4) mu mol.L-1 to 3.5 (2.9 - 4.1) mu mol.L-1 CONCLUSION: PB had dual effects on SDCN, facilitated GABAA receptor-mediated currents, and at higher concentrations induced Cl- influx itself. |
