Role of ascorbic acid versus silymarin in amelioration of hepatotoxicity induced by acrylamide in adult male albino rats: histological and immunohistochemical study

Int. j. morphol; 38 (6), 2020
SUMMARY: Acrylamide (ACR) is a cytotoxic and carcinogenic material. It is a product of a Maillard reaction during the cooking of many types of fried fast food, e.g. potato chip fries, and chicken nuggets. ACR has a severe toxic effect on different body organs. This study investigates the hepatotoxic effe...

Vitamin C administration attenuated artemether induced hepatic injury in rats

Int. j. morphol; 38 (1), 2020
This research was designed to investigate the potential protective effect of vitamin C supplementation against hepatocyte ultrastructural alterations induced by artemether (antimalarial drug) administration. Twenty-four adult male albino rats were used in this study and were divided into four groups (n=6...

Vitamin C inhibits crystallization of struvite from artificial urine in the presence of Pseudomonas aeruginosa

Int. braz. j. urol; 44 (6), 2018
ABSTRACT Background: Formation of struvite stones is associated with urinary tract infection by urease-producing bacteria. Biogenic crystal growth in natural and synthetic materials is regulated by the action of inhibitors, ranging from small ions, molecules to large macromolecules. Materials and Metho...

The role of vitamin C in the gene expression of oxidative stress markers in fibroblasts from burn patients

Acta cir. bras; 33 (8), 2018
Abstract Purpose: To assess the action of vitamin C on the expression of 84 oxidative stress related-genes in cultured skin fibroblasts from burn patients. Methods: Skin samples were obtained from ten burn patients. Human primary fibroblasts were isolated and cultured to be distributed into 2 groups:...

Evaluation of phenolic compounds and lipid-lowering effect of Morus nigra leaves extract

An. acad. bras. ciênc; 89 (4), 2017
ABSTRACT Morus nigra L. (Moraceae) is a tree known as black mulberry and the leaves are used in folk medicine in the treatment of diabetes, high cholesterol and menopause symptoms. The aim of this study was to evaluate the M. nigra leaves phytochemical profile in different extractions and the hypolipidem...

An experimental study of ascorbic acid effects in acute renal failure under general anesthesia

Acta cir. bras; 32 (10), 2017
Abstract Purpose: To evaluate the preventive effect of ascorbic acid on sevoflurane-induced acute renal failure in an experimental rat model. Methods: Twenty-four adult male Wistar rats were randomly distributed into three groups. Subjects were allocated into 3 groups: Group I received sevoflurane onl...

The preventive effects of ascorbic acid supplementation on locomotor and acetylcholinesterase activity in an animal model of schizophrenia induced by ketamine

An. acad. bras. ciênc; 89 (2), 2017
ABSTRACT Studies have shown that schizophrenic patients seem to have nutritional deficiencies. Ascorbic acid (AA) has an important antioxidant effect and neuromodulatory properties. The aim of this study was to evaluate the effects of AA on locomotor activity and the acetylcholinesterase activity (AChE) ...

Reduction of the DNA damages, Hepatoprotective Effect and Antioxidant Potential of the Coconut Water, ascorbic and Caffeic Acids in Oxidative Stress Mediated by Ethanol

An. acad. bras. ciênc; 89 (2), 2017
ABSTRACT Hepatic disorders such as steatosis and alcoholic steatohepatitis are common diseases that affect thousands of people around the globe. This study aims to identify the main phenol compounds using a new HPLC-ESI+-MS/MS method, to evaluate some oxidative stress parameters and the hepatoprotective ...

Avoiding liver injury with papaverine and ascorbic acid due to infrarenal cross-clamping: an experimental study

Abstract Objective: Ischemia-reperfusion injury after acute ischemia treatment is a serious condition with high mortality and morbidity. Ischemia-reperfusion injury may result in organ failure particularly in kidney, lung, liver, and heart. In our study, we investigated the effects of papaverine and vit...

Soluble amino acid profile, mineral nutrient and carbohydrate content of maize kernels harvested from plants submitted to ascorbic acid seed priming

An. acad. bras. ciênc; 89 (1,supl), 2017
ABSTRACT Both the scientific community and society have shown interest in improving the content of amino acids, carbohydrates and mineral nutrients in maize because it represents an important staple food in many developing countries. Earlier studies demonstrated that the treatment of seeds using ascorbic...
