Whether the generation of PSC is influenced by psychological factors of the observed subjects

it is an important problem ought to be sol ved. In this study the authors inspired the subjects by using signals of sound

li- ght and eletricity

by describing the lines of PSC with model or chart of channel

by drawing lines of PSC on the body surface of the subjects

or by giving distinct suggestions to the subjects with obvious hinting conver- sations. We have observed the PSC phenomena of the channels. In 250 first vi- sit patients the results were as follows: (1) Before strong suggestion

the rate of appearance of PSC was 2.0% in marked models

17.6% in relative marked models and 80.4% in insensi- tive models respectively. After strong suggestion

the rate of appearance was 2.0%

18.8% and 79.2% in corresponding models respectively. Comparisons in each corresponding models showed no significant differences in their statistical treatments (p>0.05). (2) Before and after the strong suggestion

the lengths of PSC lines of the Large Intestine Channel were 56.34±0.48cm and 57. 65±0.56 cm; the widths were 1.78±0.22cm and 1.97±0.22cm; the velocities were 9.23±0.41 cm/sec and 10.02±0.44 cm/sec respectively. The compared statistical results of three items had no significant diferences (p>0.05). Before and after the strong suggestion

the lengths of PSC of the Ga- llbladder Channel were 92.65±0.51 cm and 91.74±0.45cm

the widths were 2.53±0.31 cm and 2.25±0.29 cm

the velocities were 8.98±0.30 cm/sec and 8.62±0.28cm/sec respectively. The compared statistical results of three items had no significant differences (p>0.05). (3) When we made the PSC suggestions to directions of Spleen Channel and the Stomch Channel respctively at 18 Channel-times for the three subjects who had marked PSC along the Large Intestine Channel and the Pericardium channel

we did not found the deviations of PSC to the Spleen and Stomach Channel. These observed results show that strong suggestions have no obvious and important influences on PSC

and PSC phenomena are not the results of psychological effects or due to subjective factors

It reveals that the Channel lines are not noly related to the central nervous system

but also possess certain substantial structure on the body surface and definite physio- logical foundations.
