The theory Of reinforcement and reduction with acupuncture is one of the important contents ofthe needling techniques in acupuncture. In order to verify the theory

experimental fever caused by ve-nous injection of E. Bacillus coll in rabbits were treated by acupuncture at Quchi(LI 11 ) with differentneedling methods (reinforcing or reducing) and stimulations (acupuncture or electroacupuncture). Theresults showed that each of the three reducing techniques with simple rotating of needle

rotation withliftingthrusting needle and electroacupuncture presented the fever-subduing effects

especially obtain-ing the immediate effect and lowering the peak of fever. Among them

the former two had the betterresult than electroacupuncture.The reinforcing technique with rotating needle did not give rise to thesignificant effect on lowering fever'The result indicates that there exist significant differences in the effect on fever-subduing betweenrein forcing and reducing methods with acupuncture and between acupuncture and electroacupuncture.The simple reducing needling technique share the same therapeutic result with compound one. Thework provides avaluable example for further laboratory study of reinforcing-reducing theory ofacupuncture.
