Abstract:
AIM To establish a dysmenorrhea model in mice. METHODS The mice were given with some kinds of oestrogens once a day for 3～25 days. On the last day, the mice were injected intraperitoneally with oxytocin and the number of twisting body was recorded to evaluate the intensity of dysmenorrhea. The optimum conditions to establish the model was analysed statisticly. RESULTS The optimum oestrogens was stilbestrol. Stibestrol should be given for 12～15 days. The regression equation of the dose effect curve of stibestrol was =0 03?0 04 X, r =0 9688. The optimum dosage of oxytocin was 20 U?kg -1 . The dysmenorrhea model in mice could be preserved for about 7 days. 90% of the twisting body reactions concentrated in 0～30 minutes after oxytocin was given. The effect of oxytocin (20 U?kg -1 ) had significent difference with that of prostaoglantin (1 3 mg?kg -1 ). The test of uterus in vivo showed that stilbestrol could increase the uterine contraction frequency and strengthen the contractility. The dysmenorrhea model in mice was testified by some anti dysmenorrhea drugs. CONCLUSION Compared with the hypodermic implantation in rats, the dysmenorrhea model in mice was simple, reliable, economical and testifiable,etc.
