Ameliorative Effect of Natural and Synthetic Antioxidants on Arsenic Toxicity in Male Mice: Biochemical and Histological Perspectives
Sayed AmerMohammad AL-Harbi


The present study aimed to investigate the protective effects of some natural and artificial antioxidants on the hepato-renal injuries induced by arsenic toxicity. Sixty adult male albino mice weighing 30-40 g were subjected to a sub-lethal dose of sodium arsenate (40 mg/kg body weight) to investigate hematological, biochemical and histopathological alterations resulting from arsenic-induced hepato-renal toxicity. Arsenic-exposed mice were also co-treated with different antioxidants including green tea, garlic and vitamin C to reveal their potential protective role. The antioxidants induced normalization of all blood parameters that showed significant declines by arsenic toxicity. ALT and AST activities were significantly increased in sodium arsenate treated group compared to all other groups. These enzymes did not acquire insignificant differences in antioxidants-treated groups compared to the control mice. Creatinine and urea were significantly increased in arsenate treated mice and become normal in mice co-treated with different antioxidants. Liver sections of arsenate treated mice showed venous congestion, sinusoidal dilatation, mononuclear cell infiltration and periportal fibrosis. Renal sections in the same groups reveale...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
