Among the 45 neurons generating phasic firing, 8 (17.78﹪) neurons could still be induced phasic firing after treatment with 1×10-2 μg/mL SVHRP and 37 (82.22﹪) neurons had no responses to the stimulation. The AP firing of neurons was dramatically different after treatment with SVHRP (P＜0.01, n=45). Among the 7 repetitive firing neurons, all of them could only generate 1 or 0 AP instead of repetitive firing when SVHRP was applied. The number of APs was 14.57±1.00 and 0.57±0.20 before and after SVHRP treatment (P＜0.01, n=7). The AP rheobase was (75.10±8.99) pA and (119.85± 12.73) pA before and after 1 × 10-4 μg/mL SVHRP application, respectively (P＜0.01,n=8). The AP threshold was increased from (-41.17±2.15) mV to (-32.40±1.48) mV after 1×10-4 μg/mL SVHRP treatment (P＜0.01,n=8). The peak amplitude of AP was (68.49±2.33) mV for the neurons before treatment with 1×10-4 μg/mL SVHRP and (54.71±0.81)mV after treatment (P＜0.01, n=8). These results showed that SVHRP could decrease the AP firing frequency, increase the AP rheobase and threshold, but decrease the AP peak amplitude of hippocampal neurons.

在产生位相放电的45个细胞中，有8个细胞在SVHRP处理后仍可以诱发出位相放电(占17.78﹪)；37个细胞在SVHRP处理后无法诱导出位相放电(占82.22﹪)，SVHRP处理后动作电位的产生与处理前相比，有显著差异(P＜0.01，n=45)；在产生重复放电的7个细胞中，在1×10-2μg/mL SVHRP作用后均不能再次诱发出重复放电，而是产生一个动作电位或不再产生动作电位，药物处理前产生的动作电位个数为14.57±1.00，SVHRP处理后产生动作电位的个数为0.57±0.20，二者之间有显著性差异(P＜0.01，n=7)。1×10-4 μg/mLSVHRP处理后，诱发动作电位产生的基强度由(75.10±8.99)pA增加到(119.85±12.73)pA(P＜0.01，n=8)；阈电位由(-41.17±2.15)mV升至(-32.40±1.48)mV(P＜0.01，n=8)；动作电位峰值由(68.49±2.33)mV下降至(54.71±0.81)mV(P＜0.01，n=8)。
