The effects of L-ascorbic acid and its stable analogue L-ascorbic acid 2-glucoside on the restoration of liver mass and recovery of liver function after 70% partial hepatectomy (PH), were compared with other natural vitamin C analogues in rats in vivo. L-Ascorbic acid (100 mg/kg/d, intraperitoneally (i.p.))- and L-ascorbic acid 2-glucoside (50 mg/kg/d, i.p.)-treated rats showed an approximately...
abstract: Ascorbic acid (Vitamin C) is an essential Vitamin which participates in many different biological processes. The ascorbic acid content in vegetables and fruits is a maturity index and its determination in such samples is of special interest in quality control. In this paper we present a titrimetric method with potassium bromide for the determination of ascorbic acid in walnut, cabbage...
Background and Aim: Perturbations in copper (Cu) metabolism are characteristic of diabetes type I. Hyperglycemia and increased free radicals generation result in increased Cu plasma levels and leads to oxidative stress. The aim of this study was to determine the antioxidant effects of ascorbic acid on Cu plasma levels in streptozotocin (STZ) induced diabetic rats. Materials and Methods: ...
Introduction: Betaine (trimethyl glycine) is known as methyl group donor and antioxidant in previous reports. The aim of this study was to assess the antioxidant effects of betaine in Indomethacin-induced gastric damages. Methods: Thirty-two adult male Sprague–Dawley rats in an experimental study were divided into four equal groups as follow: Control, Indomethacin, Betaine-indomethacin...

1. A study was undertaken to investigate the distribution of ascorbic acid between various cellular components of blood, in normal individuals, and its relation to the plasma concentration. Forty-one unsupplemented individuals and sixteen supplemented (2 g/d for 5 d) individuals were studied. 2. Granulocytes, mononuclear leucocytes, platelets and erythrocytes were separated by differential sedi...
The aim of this study was to investigate the effect of different light intensities and ascorbic acid on some physiological and biochemical characteristics of Zinnia elegans L. The experiment was designed as a completely randomized design in a form of split-plot with three replications. The treatments were consisted of three light intensity levels (600, 1200 and 1800 μmol m-2 s-1) as the main fa...
We examined the effects of L-ascorbic acid and its analogues on DNA synthesis and cell proliferation. We also investigated the signal transduction pathways involved in the induction of mitogenesis by L-ascorbic acid and its analogues using primary cultures of adult rat hepatocytes. Following a 4-h serum-free cultivation, both L-ascorbic acid and its stable analogue, L-ascorbic acid 2-glucoside,...
L-Ascorbic acid (vitamin C) is as essential to plants as it is to animals. Ascorbic acid functions as a major redox buffer and as a cofactor for enzymes involved in regulating photosynthesis, hormone biosynthesis, and regenerating other antioxidants. Ascorbic acid regulates cell division and growth and is involved in signal transduction. In contrast to the single pathway responsible for ascorbi...
