Evaluation of Nano‐curcumin effects against Tartrazine‐induced abnormalities in liver and kidney histology and other biochemical parameters

Abstract

In the current study, 40 albino male rats were investigated to evaluate the impact of Nano-curcumin (Nano-CUR) administration against Tartrazine (TZ)-induced variations in kidney and liver histology and their related functions. The liver function biomarkers are (glutamate oxaloacetate transaminase (GOT), glutamate pyruvate transaminase (GPT), alanine aminotransferase (ALT), aspartate aminotransferase (AST), gammaglutamyl transaminase (GGT), alkaline phosphatase (ALP), total bilirubin (T. BiLL)), whereas the kidney biomarkers are (creatinine, uric acid, urea, globulin, total protein (TP)), as well as blood parameters of (serum glucose (sGlu), alpha-fetoprotein (AFP), protein Kinase-C (PKC)) and lipid profiles that include (total lipids (TL), triglyceride (TG), total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C), high-density L-C (HDL-C), and very-low-density L-C (VLDL-C)). The collected rats were randomly separated into four different groups (G1, G2, G3, and G4) of 10 rats each, where G1 stands for control, G2 for TZ-ingestion, G3 for Nano-CUR-ingestion, and G4 for (TZ + Nano-CUR mix.) ingestion. TZ-ingestion significantly (p < .05) increases the liver function enzymes' activity, total bilirubin and kidney biomarkers (creatinine, urea, uric acid, total protein (TP), globulin (Glu)). Also, TZ-ingestion significantly increased sGlu, PKC, AFP, as well as lipid profiles, while there were significant (p < .05) decreases in HDL-C and albumin (Alb) concentrations compared to control. Histopathological changes in liver, such as dilatation of blood sinusoids and central vein with hemorrhage and necrosis, were observed due to TZ-ingestion. Similarly, TZ-ingestion influenced kidney tissues in terms of tubular dilatation with tubular degeneration, thickened basement membrane, and dilatation of the glomerular capillaries. Markedly, the administration of Nano-CUR significantly decreased liver and kidney function enzymes as well as sGlu, AFP, and PKC, whereas it significantly increased serum Alb and HDL-C levels compared to control and TZ-ingested rats. All values arranged around normal control values. Also, the liver tissue of Nano-CUR-ingested rats showed a normal arrangement of normal blood sinusoids(s), hepatic cords, and hepatocytes as compared to controls.The same results were also found in the section of rat kidney ingested with 2.00 g of | 1345EL-DESOKY Et aL. | INTRODUC TI ONPeople consume various food additives every day, which have both advantages and disadvantages. Food additives have showed an important impact on food sources and provided people delicious, nutritious, and safe foods (Himri et al., 2011). Food additives are classified into six main groups including preservatives, nutritive additives, flavoring, coloring, texturizing, and miscellaneous compounds (Amin & Al-Shehri, 2018). Food colors are added to give a color to a foodstuff and to restore its usual color, which is usually attractive to consumers, especially children. The synthetic food colors are considered as the class of essential foo...

Puerarin protects against acetaminophen‐induced oxidative damage in liver through activation of the Keap1/Nrf2 signaling pathway

“…Due to the low bioavailability of puerarin in oral administration (El Desoky et al, 2022;Zhang, 2019), mice were treated with 200, 400, 800 mg kg −1 Pue for 10 days in advance and then injected intraperitoneally with 300 mg kg −1 APAP to establish the model of acute liver injury. Interestingly, we found that Pue can significantly reduce liver index in APAP injected mice.…”

“…Organ index is one of the biological characteristics that used to measure and reflects the functional state of animals, which can be used as evidence to evaluate histopathological changes, and it is also a sensitive index to judge the toxicity of drugs (Bailey et al, 2004 ). Due to the low bioavailability of puerarin in oral administration (El Desoky et al, 2022 ; Zhang, 2019 ), mice were treated with 200, 400, 800 mg kg −1 Pue for 10 days in advance and then injected intraperitoneally with 300 mg kg −1 APAP to establish the model of acute liver injury. Interestingly, we found that Pue can significantly reduce liver index in APAP injected mice.…”

Green synthesized silver nanoparticles for the treatment of diabetes and the related complications of hyperlipidemia and oxidative stress in diabetic rats

“…19 Using the biological nanoparticle sources is important for nanoscale material development, and technical tools that can be used to develop ecofriendly and reliable methodologies to synthesize such materials. [20][21][22] Accordingly, we aimed to synthesize green silver nanoparticles using cinnamon extracts (C-Ag-NPs) and study the physical and chemical characteristics of the composite nanoparticles, and to assess the biological ecofriendliness of the nanoparticles when controlling the hyperglycemic conditions and related complications disorders in streptozotocin (STZ)-induced diabetic rats.…”

“…A standard diet in the form of dry pellets and water was frequently supplied to the animals. 20 The National Institutes of Health (NIH) guides were adhered to when handling all the animals used in this study; specifically, we adhered to the guides on the caring and use of animals: NIH Publication revised (1985), NIPRD standard operating procedures (SOPs).…”
