ABSTRACT
Objective To study the therapeutic effect of resiniferatoxin(RTX)on prostatic pain from chronic prostatitis.Methods Complete Freund's adjuvant(CFA)was injected into rat bilateral ventral prostate to form chronic prostatic inflammation in 15 male SD rats.Two weeks later,RTX was injected into lumbosacral vertebral canal(n=5)or bilateral ventral prostate(n=5).Another 5 SD rats served as normal control.Neuropeptide level and the mRNA expression of substance P(SP)and calcitonin gene-related peptide(CGRP)in lumbosacral spinal cord and dorsal root ganglia(DRG)were measured by immunohistochemistry,radioimmunoassay,and RT-PCR.Results SP and CGRP level and their mRNA expression increased significantly in rat with prostatitis.Neuropeptide level and their mRNA expression were decreased after RTX was injected into vertebral canal and prostate.Conclusion Local injection of RTX can effectively inhibit synthesis and release of SP and CGRP,suggesting that RTX may be helpful to the analgesic therapy of chronic prostatitis.
