Effects of rosmarinic acid and sinapic acid on the average lens mass and lens soluble protein content in ovariectomized rats.

Parameter/Group	SHAM	OVX	OVX + ESTR	OVX + RA10	OVX + RA50	OVX + SA5	OVX + SA25
Average mass of the lens (g)	0.059 ± 0.002	0.058 ± 0.003	0.055 ± 0.002	0.055 ± 0.001	0.056 ± 0.002	0.056 ± 0.002	0.055 ± 0.001
Soluble protein (mg/g of the lens)	280.6 ± 6.8	302.5 ± 7.8	295.8 ± 5.8	290.4 ± 3.2	291.7 ± 7.2	291.9 ± 5.2	286.7 ± 4.2

Rosmarinic acid at doses of 10 mg/kg (OVX+RA10) and 50 mg/kg (OVX+RA50), sinapic acid at doses of 5 mg/kg (OVX+SA5) and 25 mg/kg (OVX+SA25) or estradiol at a dose 0.2 mg/kg (OVX+ESTR) were administered orally to ovariectomized rats, once daily for 28 days. SHAM: sham-operated control rats; OVX: ovariectomized control rats. Results are presented as the mean ± SEM. No statistically significant differences in results for both parameters were demonstrated by ANOVA.
