Abstract:
OBJECTIVE: To confirm the effect of calcitonin injection relieving pain in ovariectomized rats. METHOD: Thirty five Sprague-Dawley rats were randomly divided into five groups (high dose calcitonin group (112 U/ Kg), low dose calcitonin group (56 U/Kg), free calcitonin group, ovariectomy group, control group). To assess the pain in ovariectomized rats, the tail of rats were dived in waters of 50+/-1degrees C. Then the tail withdrawal time was measured (tail withdrawal test). The tail withdrawal test was performed in once a week for eight weeks. RESULTS: 1. At seven and eight weeks after injection, the tail withdrawal time of high and low dose calcitonin group compared with that of ovariectomy group were significantly prolonged (p<0.05). 2. At eight weeks after injection, the tail withdrawal time of free calcitonin group compared with that of ovariectomy group was significantly prolonged (p<0.05). CONCLUSION: The effect of calcitonin injection relieving pain in ovariectomized rats was found.
