Abstract:In this study, we examined the responses of the neurons in the lumbar segments of the spinal cord to nociceptive stimuli induced by formalin using c-fos immunohistochemistry and NADPH-d histochemistry Materials and Methods: Thirteen male, Wistar albino rats were used. The rats were divided into 3 groups. Group 1: pain group (n=5). Group 2: sham group (n=5). Group 3: control group (n=3). In group 1, 50 µl of 30% formalin solution was injected subcutaneously unilaterally on the dorsal surface of the right foot. … Show more
