ABSTRACT

OBJECTIVE: To determine whether or not pomegranate extract can affect postmenopausal syndrome in ovariectomized rats. METHODS: Seventy-nine female Sprague-Dawley rats were used A, no intervention; B, sham operation and distilled water; C, ovariectomy and distilled water; D, ovariectomy and 10% dilute pomegranate; E, ovariectomy and 20% pomegranate; and F, ovariectomy and 40% pomegranate. The study samples were obtained 4 weeks later. The following parameters were investigated for analyses the thickness of urogenital epithelium, tail skin temperature, serum levels of sex hormones, lipid profile, homocysteine, and thiobarbituric acid reactive substances. RESULTS: 20% pomegranate had a transient thickening effect of bladder epithelial layer. There was an intermittent lowering effect of tail skin temperature of pomegranate extract, however, it was not consistent. There were lowering effect in serum homocysteine and elevating effect in serum high density lipoprotein-cholesterol. Pomegranate did not reverse post-ovariectomy reduced sex hormone levels. CONCLUSION: Pomegranate extract showed a tendency to reverse ovariectomy-related urothelial changes. Also pomegranate had a serum homocysteine-lowering effect.
