Development of vitex-derived polymer nanofibers using electrochemical sensors for the treatment of polycystic ovarian syndrome in rats as an animal model
Abstract
Nanofibers have a high specific surface area and small pores, which increases the possibility of drug uptake. In this study, chasteberry-containing nanofibers were prepared by electrospinning to investigate their potential for polycystic follicles after induction of polycystic ovarian syndrome (PCOS). Chasteberry-containing nanofibers were identified using Fourier-transform infrared spectroscopy (FTIR), Field Emission Scanning Electron Microscopy (FESEM), and thermal gravimetric analysis (TGA) tests, as well as drug release and antibacterial tests. In this study, 42 Sprague-Dawley rats with regular menstrual cycles were divided into five groups: control group (healthy rats), polycarbonate (PC) group (treated with 1 mg/kg letrozole for 28 days to induce PCOS syndrome), and Poly terephthalate (PT) group (treated with PCOS for 30 days). Chasteberry was included at 1, 2, 4 wt%. To induce PCOS, the polyterephthalate (PT) and polycarbonate (PC) groups were administered 1 mg/kg letrozole by oral gavage for 28 days. The polyterephthalate (PT) group was treated with different doses of chasteberry-containing nanofibers (1, 2, 4 wt%). The results showed that the drug was well incorporated into the fibers and released slowly and sustainedly from the nanofibers for 30 days. Ex vivo results showed that by taking letrozole, the polycarbonate (PC) group had larger cystic follicles with a very thin granulosa layer than the control group. This is the cause of ovarian anovulation or…
How strong is the evidence?
Evidence Hub reads this as a experimental / empirical study, done in animal, not in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
