Abstract:

Osteoporosis is a metabolic skeletal disorder leading to bone fracture which adversely impacts the quality of life. In the present, we aimed to investigate the effect of Peperomia pellucida (L.) Kunth herb juice and ethanolic extract on ovariectomy (OVX)-induced osteoporotic rat model. Osteoporosis was induced by OVX with a double dorsolateral approach on female Wistar rats. Female Wistar rats undergoing sham surgeries (sham-control group) served as controls. The ovariectomized rats were divided into six groups based on administered treatments, (i) CMC Na 0.3% (OVX-control group), (ii) standard drug (ethynil estradiol 4.5 µg/kg), (iii) P. pellucida juice at dose of 50 mg/kg, and (iv) 100 mg/kg, (v) P. pellucida ethanolic extract at dose of 50 mg/kg, and (vi) 100 mg/kg. Treatments were started 1 week after the surgeries and lasted for 6 weeks. Rats treated with 100 mg/kgP. pellucida ethanol extract had significantly decreased serum ALP level and reduced excretion of urine calcium compared with the OVX-control group (P<0.05). These levels were not significantly altered when compared with the sham-control group (P<0.05). Furthermore, 100 mg/kg ethanolic extract-treated group showed improvement on three-dimensional image of the trabecular bone compared with the OVX-control group. Trabecular cavity formation in 100 mg/kg ethanolic extract-treated group was minimal. Ethanolic extract of Peperomia pellucida (L.) Kunthherbs at a dose of 100 mg/kg had preventive effect on OVX-induced osteoporotic rats.
