Many factors

such as the selection of acupoints

the interval between acupunctures

the acupuncture time

the manipulation and the specification of acupuncture needles

are capable of affecting curative effects

There were some studies on these factors ago. However each of these studies only related to a single factor. These stlldies could not reflect the clinical truth

and could not provide accurate overall data for rnedical staff. ln order to solve the above problems

we carried out an animal experiment designed by L9 (34) orthogonal design. The experiment which consisted of 9 acuouncture groups and 3 control ones was carried out in lO8 rats

which were suffered from experirnental gastric ulcer. In the experiment

the body weight

ulcer area

plesrna SoD and LPO of each rst were observed.The results showed that in the acupuncture treatments for experimental gastric ulcer in rats

10 minutes' electric acupuncture treatment using thinner needles and the method that each rat was treated every other day were the best methods. The reason why the above results came into being was elucidated in this paper
