Objective To observe the effect of electroacupuncture(EA)intervention on expression of cytochrome P 450 side chain cleavage(P 450scc)and 17β-hydroxysteroid dehydrogenase 3(17β-HSD3)in the testis in partial androgen deficiency of aging male(PADAM)rats so as to reveal its mechanism underlying improving PADAM.Methods Thirty male SD rats were randomly and equally divided into control
model
and EA groups.The PADAM model was established by intraperitoneal injection of cyclophosphamide(20mg·kg-1·d-1)
once daily for 5days.EA(20-30 Hz
1-3mA)was applied to bilateral"Shenshu"(BL 23)and"Guanyuan"(CV 4)for 15 min
once daily for 8weeks.Serum total testosterone(TT)and free testosterone(FT)levels were measured using enzyme-linked immunosorbent assay(ELISA).The expression levels of P 450scc/17β-HSD3 proteins and mRNA in the testis tissue were assayed by immunohistochemistry
Western bolt(WB)and RT-polymerase chain reaction(RTPCR)
separately.Results Compared with the control group
both serum TT
FT levels and expression levels of P 450scc/17β-HSD3 proteins and mRNA in the testis tissue in the model group were significantly down-regulated(P<0.01).After EA intervention
compared with the model group
the cyclophosphamide-induced decrease of serum TT
FT levels and the expression levels of P 450scc/17β-HSD3 proteins and mRNA in the testis was reversed in the EA group(P<0.01).Conclusion EA intervention is effective in up-regulating serum TT and FT
testicular P 450 scc and 17β-HSD3 proteins and mRNA levels in PADAM rats
which may be one of its mechanisms underlying improvement of PADAM.
