Abstract
Objective:
Evaluation of uterine activity (U A) before and after acupuncture stimulation and the influence of central nervous system (CNS) on UA
Methods:
We used 16 female Wistar rats, 7 pregnants and 9 non-pregnants, deeply anaesthesied. In 8 animals (6 non pregnant and 2 pregnant) we placed electrodes at cerebral cortex (areas 3 and 10) and hypoccampus(area CAI). All animal had a pairofelectrodesat uterus. Pregnant rats, between 14-19 days of pregnancy, after 30 minutes initial observat ion, are submitted to 90 minutes of electroacupuncture at acupoints Sanyinjiao (SP-6) and Zuzanli (S-36).
Results:
The uterine activity were similar in pregnant (1,87 contractions/ 3 minutes) and non pregnant rats (1,82 contractions/ 3 minutes, p > 0.1). After eleclroacupuncturte, the number of events rises for 1,87/3minutes to (23,21/3minutes;p>0.01).In 3 rats( 1 non-pregnant and 2 pregnants), after anesthesias, we find correlation between the rise of cerebral activity (cortex and hipoccampus) and the uterine activity. Using Bi-Digital O-Ring Test (BDORT) resonance phenomenon originally found and developed by Prof Omura, Y. of New York between two identical substances with a piece of rat’s uterus as a control substance we found resonance with the dorsal part of hipoccampus (CAI area) and surrounding cerebral cortex.
Conclusions:
Uterine activity rises after 90 minutes of electroacupuncture in Wistar pregnant rats, and activation of CNS may be involved in this phenomenon.
