Abstract:
First in the literature this study aimed to investigate the effects of Tartrazine, a common industrial food dye, on kidney and whether Thymoquinone has a protective effect in tartrazine-induced nephrotoxicity. The study conducted on the rats bred at İnönü University Experimental Animals Production and Research Center. Wistar albino rats were randomly divided into 4 groups, where each group included 8 rats: control, Tartrazine, Thymoquinone, and Tartrazine + Thymoquinone groups. The experiments continued for 3 weeks and then, kidney tissues and blood samples were collected from the rats under anesthesia. Malondialdehyde (MDA), super oxidized dismutase (SOD), total oxidant status (TOS), increase in Oxidative stress index (OSI), glutathione (GSH), Glutathione peroxidase (GSH-Px), catalase (CAT), Total antioxidant status (TAS) levels decreased in the kidney tissues collected from the tartrazine group. Serum Bun and Creatinine levels increased in the tartrazine group. Tartrazine administration damaged and degenerated the glomeruli and cortical distal tubes in the histopathology of kidney tissues, also different degrees of inflammatory cell infiltration were observed in the renal cortex and medulla. Thymoquinone and tartrazine administration improved both biochemical and histopathological parameters. Tartrazine administration induced nephrotoxicity. This could be observed with the increase in oxidant capacity and the deterioration of kidney functions. Thymoquinone was observed to demonstrate strong antioxidant properties. Thymoquinone could be used primarily as a protective agent against Tartrazine-induced toxicity.
Insights
This study reveals that the food dye Tartrazine causes kidney damage by increasing oxidative stress. However, Thymoquinone effectively protects against this Tartrazine-induced nephrotoxicity due to its potent antioxidant properties.
Area of Science:
- Toxicology
- Pharmacology
- Biochemistry
Background:
- Tartrazine is a widely used synthetic food dye with potential adverse health effects.
- Nephrotoxicity is a significant concern associated with exposure to certain industrial chemicals.
- Thymoquinone, derived from Nigella sativa, is recognized for its antioxidant and anti-inflammatory properties.
Purpose of the Study:
- To investigate the impact of Tartrazine on kidney function and structure.
- To evaluate the protective efficacy of Thymoquinone against Tartrazine-induced nephrotoxicity in a rat model.
Main Methods:
- Wistar albino rats were divided into four groups: control, Tartrazine, Thymoquinone, and Tartrazine + Thymoquinone.
- Animals were treated for three weeks, followed by the collection of kidney tissues and blood samples.
- Biochemical markers of oxidative stress (MDA, SOD, TOS, OSI, GSH, GSH-Px, CAT, TAS) and kidney function (BUN, Creatinine) were analyzed.
- Histopathological examination of kidney tissues was performed to assess structural damage.
Main Results:
- Tartrazine administration led to increased oxidative stress markers and elevated BUN and Creatinine levels, indicating kidney dysfunction.
- Histopathology revealed glomerular and tubular damage, along with inflammatory infiltration in the kidneys of the Tartrazine group.
- Co-administration of Thymoquinone with Tartrazine significantly improved biochemical parameters and ameliorated histopathological damage.
- Thymoquinone treatment alone did not show adverse effects and maintained normal kidney function and structure.
Conclusions:
- Tartrazine induces significant nephrotoxicity, characterized by oxidative stress and impaired kidney function.
- Thymoquinone exhibits potent antioxidant and protective effects against Tartrazine-induced kidney damage.
- Thymoquinone holds promise as a therapeutic agent to mitigate Tartrazine-induced toxicity.
