SIN alleviates inflammatory pain induced by CFA. (A) Mechanical withdrawal threshold after injection; (B) Thermal withdrawal latencies after injection; (C) Frequency responses to cold stimulation after injection. Saline: rats were injected with 100 μl saline only; Saline+SIN: rats were injected with 30 mg/kg SIN and 100 μl saline; CFA: rats were injected with 100 μl CFA only; CFA+SIN: rats were injected with 30 mg/kg SIN and 100 μl CFA. * p<0.05 vs. Saline group; # <0.05 vs. CFA group.
