Abstract: The attenuating effect of 150 mg/kg of N-acetylcysteine (NAC) against the oral administration of 7.88 and 202.07 mg/kg/day for 14 days of either chlropyrifos-ethyl (CPE-E) or chlropyrifos-methyl (CPF-M), respectively, in male rat was investigated using biochemical and genetic markers. Biomarkers such as acetylcholinesterase (AChE), butyrylcholinesterase (BuChE), paraoxonase (PON), adenosine 5'-triphosphatase (ATP-ase), glutathione-S-transferase (GST), catalase (CAT), glutathione reduced (GSH) in serum showed a significant decline in their levels, while calcium (Ca+2), cytochrome C reduction (CYC-R), lipid peroxidation (LPO), nitric oxide (NO) levels showed a significant increase in serum of treated rats. Regarding the genotoxic parameters, when rats are treated either with CPE-E or CPF-M, liver DNA, chromosomal aberration (CA), and micronucleated polychromatic erythrocytes (MnPCE) significantly increased, while the mitotic index (MI) and polychromatic erythrocytes (PCE)/ normochromatic erythrocytes (NCE) ratio were significantly decreased. However, the administration of NAC following the intoxication of CPF-E or CPF-M attenuated the tested biochemical and genotoxic markers. It can be concluded that NAC can be used to ameliorate the toxicity of certain organophosphorus compounds such as CPF-E and CPF-M.
TL;DR: These remarkable hazardous effects of SO2 on male albino mice could be used as a potential guide for the prediction of its human health impact, and consumers could be advised to prevent excessive consumption of the drink (Qamar Al-Deen) prepared from dried apricot leather.
Abstract: Sulphur dioxide (SO2) is used as a preservative in food to prevent its discolouration, and to inhibit the growth of bacteria. Little data is available concerning its in vivo hazardous impact.The present study is therefore designed to examine the cyto-genotoxic potential and the testicular histological alterations in adult mice, induced by SO2 present in the dried apricot leather used to prepare the oriental drink Qamar Al-Deen. Two different forms of drinks were tested; cold and boiled drinks. Animals were placed into 4 groups. The first group received distilled water as a negative control.The second and third groups received orally the drink for 28 days in the form of a cold and a boiled drink, respectively. Animals of the fourth group received cyclophosphamide, they were used as a positive control for cyto-genotoxic tests. The chromosomal aberrations, as well as sperm abnormalities, were significantly elevated in animals that received the two different drink preparations. The mitotic index significantly decreased in comparison with negative and positive controls. Furthermore, histological examination showed different degrees of alterations in the testis. Our results suggest that the presence of SO2 inside the apricot leather might be responsible for these changes. Thus, these remarkable hazardous effects of SO2 on male albino mice could be used as a potential guide for the prediction of its human health impact. Furthermore, consumers could be advised to prevent excessive consumption of the drink (Qamar Al-Deen) prepared from dried apricot leather.
TL;DR: Results showed that the administration of the P. mildbraedii leaf extract restored the levels of the plasma enzymes, blood proteins, urea, and creatinine close to normal control levels, which were altered by the crude oil-contaminated diet, and the number of chromosomal aberrations were fewer in treated rats than in the untreated intoxicated rats.
Abstract: This study evaluated the ameliorative potential of the aqueous leaf extracts of Pterocarpus mildbraedii against crude oil-induced toxicity in rats. The effects of co-administration of the P. mildbr...
