ABSTRACT
Exposure to dust storm particulate matter (PM) is detrimental to kidney tissue. In this study, the impacts of chronic intake of dusty PM were explored as a major objective in a specified compartment to make a real-like dust storm (DS) model, and the role of hesperidin (HSP) as an antioxidant on kidney tissue was assessed in rats. Thirty-two male Wistar rats (200-220 g) were randomly allocated into 4 groups CA+NS (clean air and normal saline as a vehicle of HSP). Dusty PM and NS (DS+NS). HSP+ CA rats received 200 mg/kg of HSP by gavage for 28 days, once daily in addition to exposure to clean air. HSP+DS HSP plus DS. In DS groups, the animals were exposed to dust storms at a concentration of 5000-8000 µg/m3 in the chamber for 1 h daily, for 4 consecutive weeks, except Thursdays and Fridays. At the end of the experiment, the animals were sacrificed for biochemical, inflammatory, oxidative stress, molecular parameters, and histological evaluation. DS significantly enhanced blood urea nitrogen and creatinine, inflammatory (tumor necrosis factor-α, and interleukin-1ß), and oxidative stress indexes. Likewise, a significant increase was seen in mRNA Smads, collagen-I, and transforming growth factor-ß1 (TGF-ß1) expressions in the kidney. Histological findings showed contracted glomeruli and kidney structure disorder. In addition, Masson's trichrome staining demonstrated renal fibrosis. Nevertheless, HSP could significantly reverse these changes. Our data confirmed that DS results in kidney fibrosis through enhancing Smads/TGF-ß1 signaling. However, HSP was able to inhibit these changes as confirmed by histological findings.
