Two-day and 15-day-old offspring of capsaicin-pretreated Wistar rats were given subcutaneous injections of a 5% formalin solution to the dorsal aspect of the right forepaw. One hour after injection, acid phosphatase activity of the substantia gelatinosa of formalin/capsaicin cervical sections was significantly greater bilaterally than in saline/capsaicin 15… (More)
