The action of the emitted qi was tested on axon diaphragmatic and culture neuron cell of rat by using the voltage clamp and patch clamp technique in electrophysiology. The excitable activity of the emitted qi was determined by the single sodium channel. The results are summarized as follows.

1. Under the condition of the voltage clamp, holding potential = —50 mV, Vm = —lO mV, the peak inward sodium current INa = —0.46±0.02 uA cm when the emitted qi was applied to the left or right hand at a distance O.5 m for 12 min., INa=-O.70±0.01 uA cm. The peak of sodium current increased by about 40%, the control was by about 2.7%.

2. The sodium channel of culture neuron had one type of magnitude. Single channel currents had conductance of 10.6±0.01 pS in normal. The open-time of the sodium channel was usually 2.1±0.02 ms. When the emitted qi was applied directly to the culture neuron membrane with the hand at a distance 0.5 m for 14 min., conductance of 16.7±0.02 pS. The open-time of the sodium channel increased by the emitted qi was not modified.
