Abstract

Abstract

Interest in phytochemical therapy methods in the treatment of diabetes is increasing day by day. Although the antidiabetic and

antioxidant effects of Cistus laurifolius L. (CL) have been mentioned, the systemic effects remain unknown. The present study aims

at evaluating the antidiabetic effects of the CL aqueous extract via metformin on streptozotocin (STZ)-induced diabetic rats. Forty male

Wistar albino rats were divided into five groups of eight animals each: control, diabetic group (55mg/kg STZ), STZ+125mg/kg CL,

STZ+250mg/kg CL, and STZ+100mg/kg metformin. The effects of CL and metformin on oxidative, apoptotic, and inflammatory

pathways were comparatively investigated. In addition, nuclear factor-κB(NFκB), tumor necrosis factor-alpha (TNF-α), and interleukin

(IL)-1β expressions analysis were carried out. CL treatment resulted in a significant improvement in blood glucose levels, lipid profile,

pancreatic markers, and liver and kidney function tests. A 250mg/kg CL treatment decreased by 67.9%, 31.6%, 66.8%, 28.3%, and

31.4% in the total oxidant capacity, NFκB, TNF-α, IL-1β, caspase3, and cytochrome c levels, respectively, compared to the diabetic

group. Additionally, CL treatments showed a dose-dependent reduction in NFκB, TNF-α, and IL-1β expression levels. A 250mg/kg

CL treatment exhibited a greater increase (by 9.6%) in total antioxidant capacity than metformin. CL treatment provided histologically

more improvement in the brain, heart, pancreas, spleen, liver, kidney, and testicular tissues compared to the metformin group. Our

results suggest that the single treatment of CL aqueous extract at the low doses may have stronger short-term anti-diabetic effects than

metformin. Therefore, further studies are needed regarding the long-term hypoglycemic effect or treatment of CL aqueous extract.
