PURPOSE Many systemic and local factors contribute to gastrointestinal tract anastomoses dehiscence, which is a serious and potentially fatal postoperative complication. The aim of this study was to evaluate the effects of omega-3 fatty acid and ascorbic acid on the healing of ischemic colon anastomosis. PATIENTS AND METHODS 40 Wistar Albino rats weighing between 180 and 220 g were divided in...

It has recently been reported that glucose and its analogues inhibit in vitro ascorbic acid transport across the cell membrane of polymorphonuclear leukocytes and fibroblasts. We have studied the effect of in vivo hyperglycemia on the intracellular ascorbic acid level of mononuclear leukocytes in normal and diabetic human subjects. Administration of an intravenous glucose load resulted in a pro...

Forty-one asthmatic patients in remission were randomly allocated to two treatment groups in a double-blind trial. One group took 1 g, of ascorbic acid as one effervescent tablet once daily and the second group took a matching placebo. The asthmatics were selected from those attending the Asthma Clinic. One criterion for selection was the increase in exacerbation during the rainy season. These ...

In order to study the potential benefit of ascorbic acid in asthma we investigated its role in exercise-induced bronchospasm (EIB). Twelve asthmatic subjects were recruited on the basis of findings compatible with EIB. On two subsequent days the subjects ingested 500 mg. of ascorbic acid or a placebo. The study was performed in a double-blind randomized fashion. Partial and maximal expiratory f...

The respective and combined effects of sodium chloride, ascorbic acid, citric acid, potassium sorbate, and Thymus vulgaris extract on the growth of Aeromonas caviae and Aeromonas sobria were investigated. Sodium chloride (3%) significantly reduced the growth and 4% NaCl inhibited growth of the tested strains. Ascorbic acid (0. 1%), potassium sorbate (0.05%), and citric acid (0.03%) slightly inh...

HYPOTHESIS High-dose ascorbic acid (vitamin C) therapy (66 mg/kg per hour) attenuates postburn lipid peroxidation, resuscitation fluid volume requirements, and edema generation in severely burned patients. STUDY DESIGN AND SETTING A prospective, randomized study at a university trauma and critical care center in Japan. SUBJECTS AND METHODS Thirty-seven patients with burns over more than 30%...

Ascorbic acid (vitamin C) has major effects on the intestinal uptake and utilisation of Fe in humans. The objective of the present study was to investigate the impact of Fe on the acquisition of ascorbic acid. The strategy was to study the cellular uptake and transport of ascorbic acid in the presence of Fe and also to observe the expression of the Na-dependent vitamin C transporter 1 (SVCT1) p...

Although it is generally realized that environmental factors may influence the nutritive value of fruits and vegetables, there has not been a great deal of research reported to show the extent to which climatic variants may exert their effect. The work reported in this paper is concerned with the relationship between sunlight and the ascorbic acid content of strawberries. Reports in the literat...

BACKGROUND Cross-sectional data suggests that a low level of plasma ascorbic acid positively associates with both Body Mass Index (BMI) and Waist Circumference (WC). This leads to questions about a possible relationship between dietary intake of ascorbic acid and subsequent changes in anthropometry, and whether such associations may depend on genetic predisposition to obesity. Hence, we examine...
