Abstract:
Objective To examine the heating capability of thermoseeds in isolated hepatic tissues.Methods Isolated hepatic tissues were heated uniformly to 37 ℃,meanwhile the thermoseeds and thermocouples were planted using a template paralleling with the magnetic line.Afterwards,the tissues were treated in an extracorporeal magnetic field of 120-123 gauss at a frequency of 113-116 kHz for 30 minutes.At the meantime,the temperature was recorded by a computer through thermocouples. Results The temperature of the tissues raised markedly with a largest change of 14 ℃.The heating area became hard and showed a gradual change of color(white-yellow-brown).The final temperature was negatively correlated with distance when using same number of the thermoseeds(r=-0.96017 to-0.99767,P=0.0023 to 0.0398),and positively correlated with the number of thermoseeds when measuring at a same point(r=0.93775 to 0.99270,P=0.0007 to 0.0185)except for the center group(r=0.93936,P=0.0606).Conclusions Thermoseeds inductive heating technology can achieve an appropriate temperature in isolated hepatic tissues.In certain extent,the temperature increase the number of thermoseeds and heating distance.
