Abstract
Saw palmetto (SAW), the herbal drug used to treat prostatic hyperplasia, exerts its antiproliferative effects by blocking steroid 5 alpha-reductase (SRD5A1) activity, that has also been involved in gingival hyperplasia (GH) pathogenesis. Concurrently, folic acid (FA) could reduce GH prevalence via its antioxidant and anti-inflammatory effects. Thus, this study tended to assess the potential therapeutic efficacy of SAW, alone and along with FA, against amlodipine-induced gingival inflammation and overgrowth in rats. Rats were grouped into (CONT, AIGH, SAW, SAW-treated, FA-treated, and SAW + FA-treated). SAW and FA were administered once daily for 4 weeks. Gingival SRD5A1, CTGF, GSK-3β, and NLRP3 expressions, as well as T, DHT, MDA, TAC, ET-1, and MMP2 levels were determined. In addition, histopathological and immunohistochemical analyses of TNF-α, IL-6, TGF-β1, and α-SMA were documented. Results declared that SAW and FA administration markedly ameliorated amlodipine-associated GH and may be presenting a novel therapeutic avenue in the future.
