RESUMO

Diabetes mellitus is one of the chronic metabolic diseases whose control remains a challenge. Its increased incidence was mainly attributed to increased environmental contamination. Therefore, this study aims to investigate the effect of feeding clover microgreen (CM) on a diabetes model with or without aflatoxin exposure. Rats were distributed into 8 groups. G1 was a control group. G2 was fed CM. G3 was administered aflatoxin orally. G4 was fed clover and administered aflatoxin. G5 was diabetic rats. G6 was diabetic rats fed CM. G7 was diabetic rats administered aflatoxin. G8 was diabetic rats administered aflatoxin and fed CM. Phytochemical analysis of the CM showed that gardenin was the most common compound. The administration of aflatoxin aggravated diabetes. The groups fed CM showed a decreased glucose concentration compared to the unfed groups. Liver and kidney function parameters were improved by CM. The histopathological alteration of the pancreas, liver, and kidneys was relieved in CM-fed groups. The area % of insulin in islets of Langerhans was increased in CM-fed groups. Feeding CM also enhanced the oxidative stress biomarkers. In conclusion, CM improved all evaluated parameters in diabetic rats either exposed to aflatoxin or not compared to the control.

RESUMO

Diabetes mellitus type 2 remains one of the common diseases nowadays. Several risk factors can be implicated like increased environmental pollution. This study is aimed at evaluating the toxic effect of aflatoxin on diabetes mellitus and possible protection using natural food like radish microgreen (RM). Forty-eight male rats were randomly assigned to 8 groups: G1 control group, G2 RM group, G3 aflatoxin group, G4 aflatoxin-RM group, G5 diabetic group, G6 diabetic RM group, G7 diabetic-aflatoxin group, G8 diabetic, aflatoxin, RM group. Phytane and citronellyl tiglate were the main phytochemicals present in RM. The glucose and insulin levels were the worst in G5 and G7 groups. RM feeding restored glucose level to normal but did not alter insulin level. Insulin resistance was decreased, and insulin sensitivity was increased in groups fed RM. Liver and kidney function parameters and LDH activity were improved in groups fed RM. Histopathology of the pancreas and immunohistochemistry of insulin in pancreatic islets was improved in groups fed RM. In RM fed groups, the MDA content was decreased, whereas GSH content and antioxidant enzymes activity were increased. In conclusion, feeding RM in diabetic and/or aflatoxicated groups improved all evaluated parameters which could be due to its antioxidant potential.

RESUMO

Diabetes mellitus type 2 (DM) is a common chronic disease worldwide, which may be due to increased environmental pollution. Aflatoxin B1 is a likely inevitable contaminant in food and dairy products. Both DM and aflatoxicosis exert a deleterious effect on reproduction urging the exploration of various functional food for protection. This study investigated the effect of barley microgreen (BM) on reproductive disorders caused by DM with or without aflatoxicosis in male rats. Rats were divided into eight groups; G1 control, G2 barley, G3 aflatoxin, G4 aflatoxin-barley, G5 streptozotocin (STZ), G6 STZ-barley, G7 STZ-aflatoxin, and G8 STZ-aflatoxin-barley. BM chemical composition revealed elevated calcium, iron, phosphorus, and vitamin A compared with barely seeds. Complete blood picture, lipid profile, serum oxidative stress parameters, relative testicular weight, sperm analysis, chromosomal aberration, and testis histopathology were performed. The lipid profile was altered significantly in G7. Oxidative stress was increased in G3, G5, and G7, whereas it was decreased in BM-treated groups. Sperm counts were reduced significantly in aflatoxin and/or STZ groups but increased significantly in BM-treated groups. Sperm morphological abnormalities and chromosomal aberrations were decreased significantly in BM-treated groups compared with untreated groups. Testicular histopathology revealed moderate diffuse degeneration of seminiferous tubules in aflatoxin and/or STZ groups, which were alleviated in BM-treated groups. In conclusion, aflatoxin and STZ together caused severe reproductive disorder and oxidative stress more than aflatoxin or STZ alone. BM diet reduced significantly oxidative stress and reproductive disorder associated with DM and aflatoxicosis in rats.

RESUMO

Organophosphorus pesticides (OPPs) cause great risk to human health as they are used globally. Therefore, the purpose of this research was to determine the total phenolics, flavonoids, and antioxidant activity of agricultural waste, as well as to control the pesticide residues (diazinon, and parathion) at a laboratory scale level using dried-milled fruit wastes. The pesticide residues parathion and diazinon were used at concentrations of 0.094, and 1.90 mg/mL respectively. The fruit wastes used in this study were orange and banana peels, as well as date stones, and they were used in two concentrations (3 and 9 g/30 mL deionized water). The total phenolic and flavonoid contents and the antioxidant activity were measured in fruit wastes. Also, the Fourier transmitted infrared (FTIR) spectra of fruit wastes were established to figure out the nature of the functional groups found before and after pesticide residues removal. The ability of fruit wastes to remove pesticides residues was determined using Gas Chromatography/Mass spectrometry (GC/MS). Data showed that date stones contained a higher amount of total phenolic content than orange and banana peels. However, orange peels contained a higher amount of total flavonoid contents than those of date stones and banana peels. As for antioxidant activity, banana peels recorded the higher antioxidant activity, followed by orange peels and date stones respectively. Results revealed that there was no relation between total phenolic content, total flavonoid content, and antioxidant activity. Results also indicated that date stones at a concentration of 9 g successfully reduced diazinon (81.18%), followed by banana (63.86%) and orange peels (43.42%) respectively, whereas parathion was reduced by banana peels at a concentration of 9 g (50.34%), followed by orange peels (45.28%), and date stones (39.52%) respectively. This study demonstrated that agricultural wastes were effective in the adsorption of diazinon from water, and their use is considered safe for the environment.

RESUMO

Increased environmental pollution and unhealthy lifestyle are blamed for escalated chronic diseases. Exposure to aflatoxins was recently suggested to have a role in the increased incidence of type 2 diabetes mellitus. Diet modification and consumption of different functional food are now gaining attention, especially in diabetes management. This study investigates the effect of a diet containing barley microgreen against diabetes induced by streptozotocin with or without aflatoxin administration in rats. Barley microgreen was rich in 3'-Benzyloxy-5,6,7,4'-tetramethoxyflavone (48.8% of total) followed by 5ß,7ßH,10α-Eudesm-11-en-1α-ol (18.46%). Streptozotocin injection and/or aflatoxin administration significantly elevated glucose level, decreased insulin level, decreased ß-cell function, deteriorated liver and kidney function parameters, and induced oxidative stress in the liver. Histopathology revealed irregular small-sized islets and decreased area % of insulin-positive beta cells in the pancreas, hepatic degeneration, nephropathy, and neuropathy in diabetic and/or aflatoxin administered rats compared to control. Barley microgreen diet fed to diabetic rats with or without aflatoxin alleviated all evaluated parameters. Barley microgreen diet also ameliorated the toxic effect of aflatoxin. In conclusion, exposure to aflatoxin aggravated diabetes and its complication. The incorporation of barley microgreen in the diet was able to control type 2 diabetes mellitus and the improved outcomes observed with barley microgreen treatments involved or occurred in conjunction with improved biomarkers of oxidative stress.

RESUMO

Lifestyle and diet preferences are primarily responsible for developing type 2 diabetes. In this study, okara was manufactured into okara whey crackers (OWC) to investigate its dietary role in controlling diabetes in streptozotocin-diabetic rats with and without a high-fat diet. Forty-eight rats were divided into eight groups. G1-G4 were nondiabetic and fed a basal diet, a basal diet with 30% crackers, high fat diet, and a high-fat diet with 30% crackers, respectively. G5-G8 were diabetic groups that received similar diets as previous groups. Blood glucose, liver function, lipid pattern, pancreas and liver histopathology, and insulin immunohistochemistry were performed. OWC improved measured parameters and histopathology of the liver and pancreas in diabetic rats. The area % of positive insulin cells was increased in G6 (5.20%) and G8 rats (2.83%) fed OWC compared to diabetic rats (1.17%). In conclusion, the use of 30% OWC in a semi-modified diet has controlled the hyperglycemia and hyperlipidemia associated with diabetes.

RESUMO

Hairy root culture is a promising alternative method for the production of secondary metabolites. In this study, transformed root of Linum usitatissimum was established using Agrobacterium rhizogenes A4 strain from root cultures for lignans, phenolic acids and antioxidant capacity determination. Total lignin content (secoisolariciresinol diglucoside, secoisolariciresinol and matairesinol) was 55.5% higher in transformed root cultures than in the non-transformed root culture. Secoisolariciresinol was detected in higher concentration (2.107 µmol/g DM) in the transformed root culture than non-transformed culture (1.099 µmol/g DM). Secoisolariciresinol diglucoside and matairesinol were exclusively detected in the transformed root culture, but were not found in the non-transformed root culture. The overall production of phenolic acids in transformed roots was approximately 3.5 times higher than that of the corresponding non-transformed culture. Free radical scavenging DPPH˙ and ABTS˙+ assays showed 2.9-fold and 1.76-fold higher anti-oxidant activity in transformed root culture as compared to non-transformed.

RESUMO

The present work is aimed to investigate the toxicity of 1/20 LD50 of cadmium chloride (CdCl2) on male albino rats by oral ingestion and to determine the hepatoprotective effect of Solanum nigrum Linn (SN) dried fruits and their ethanolic extract against CdCl2 toxicity using biochemical parameters. Rats were divided into six groups; the first group is control, second group is CdCl2-intoxicated rats, third group is fed with a semi-modified diet with S. nigrum fruits, fourth group rats ingested with dried extract, and intoxicated rats (groups 5 and 6) were treated with fruits and ethanolic extract of S. nigrum, respectively. The results showed that rats exposed to CdCl2 induced remarkable decrease in body weight gain, feed efficiency, and Hb, Hct, RBC, and WBC count and MCHC, but increase in MCV and MCH values. In the case of plasma enzymes, there were significant stimulations observed in ALT and AST, acid phosphatase, alkaline phosphatase, and LDH activities of CdCl2-intoxicated rats (group 2) compared to control (group 1). Plasma protein profile showed decreases in total soluble protein and albumin; also globulin content was decreased by CdCl2 ingestion. Under the same condition, plasma total bilirubin and glucose levels were increased in group 2. In addition, lipid peroxidation and antioxidative system (GSH, catalase, and SOD) of liver were harmed by CdCl2 ingestion. Whereas, normal rats treated with SN showed insignificant changes in groups 3 and 4 as compared to control (group 1). The treatment with dried fruits and their ethanolic extract in CdCl2-intoxicated rats (groups 5 and 6) ameliorated and improved these harmful effects in all above parameters either for blood or liver. The results of this study suggest the protective effect of S. nigrum against liver injury happened by CdCl2 which may be attributed to its hepatoprotective activity and thereby.
