The effects of Cannabis sativa L. seed (hempseed) in the ovariectomized rat model of menopause.
Cannabis sativa L. has been used for the treatment of various gynecological diseases in traditional medicine. The potential of this plant to protect against complications of menopause has been raised but rarely studied. Twenty female rats were divided into five groups: sham-operated (sham), ovariectomized (OVX) and three other ovariectomized groups: HST1%, HST2% and HST10% which received 1%, 2% and 10% hempseed, respectively, in their diet for 3 weeks. The effects of hempseed on plasma lipid and lipoprotein profiles, estradiol and calcium levels were evaluated. Rats were tested for behavioral changes using the forced swimming test. The results showed that ovariectomy, independent of the type of diet, caused elevation of plasma calcium, total cholesterol and HDL-cholesterol levels, while hempseed modified this effect. Plasma estradiol levels were significantly lower in the OVX group compared to other groups. The swimming times for the OVX and sham groups were significantly shorter than that of the HSD10% group. All hempseed-treated groups were less anxious and showed significant declines in fecal boli compared to the sham group. The exploratory diving percent decreased in the HST10% group compared with other groups. These results suggest that hempseed may improve post-ovariectomy complications in rats.
