Objective To study the subchronic toxicity of sodium fluoride on mRNA expression of estrogen receptor(ER) in female mice.Methods Forty female mice were randomly divided into 4 groups according to body mass,10 in each group,and exposed to sodium fluoride solution(0,1,5,25 mg/L) through drinking water in control,low-dose,medium-dose and high-dose groups for 12 weeks.The expression levels of ERα,ER3 mRNA in ovarian tissues were determined by RT-PCR method.Results The relative expression levels of ERα,ERβ mRNA in control,low-,medium-and high-dose groups were 0.7028 + 0.0474,0.7195 ± 0.0552,0.6479 ± 0.0590,0.5684 ± 0.0513 and 0.8418 ± 0.0131,0.7729 ± 0.0974,0.7610 ± 0.0984,0.8026 ± 0.0234,respectively.The difference between high-dose and control groups of the expression level of ERα was statistically significant (P ＜ 0.05).Conclusions The subchronic toxicity of fluoride can decrease the expression of estrogen receptor in ovarian tissue,which may have a certain effect on reproductive development of female mice.

AIM:To establish a method for GC fingerprint determination of the chemical constituents in the volatile oil of Eucalyptus globulus Labill.in Yunnan Province,China. METHODS: GC was used to optimize the fingerprint determination method,and to identify the main peaks in the GC fingerprint. RESULTS: 16 mutual peaks were gained on the base of 10 batches of samples. CONCLUSION: Stable and reproducible GC fingerprint is helpful to further analyze the volatile oil constituent of Eucalyptus globulus Labill.
