This study aimed to compare the antioxidant content and antioxidant capacity of pulp and peel of two varieties of pomelo fruit (Tambun White and Tambun Pink). Antioxidants including total phenolic content, total flavonoid content and ascorbic acid content were determined using Folin-Ciocalteu reagent assay, aluminium chloride colorimetric assay and AOAC method, respectively. Antioxidant capacit...

Ascorbic acid and Mg-ATP were found to regulate norepinephrine biosynthesis in intact secretory vesicles synergistically and specifically, using the model system of isolated bovine chromaffin granules. Dopamine uptake into chromaffin granules was shown to be unrelated to the presence of Mg-ATP and ascorbic acid at external dopamine concentrations of 7.5 and 10 mM. Under these conditions of dopa...

methemoglobinemia is a disorder characterized by the presence of a higher than normal level of methemoglobin. prilocaine which is one of the oxidizing local anaesthetics is widely used in many local procedures. the first choice of treatment of complications due to the use of these local anaesthetics is methylene blue, while ascorbic acid is the alternative choice. the side effects of metilen bl...

background combining different analgesic drugs for improvement of drug efficacy is a recommended strategy intended to achieve the optimal therapeutic effects. objectives the purpose of the present study was to assess the nature of the interaction between ascorbic acid and two analgesic drugs, morphine and tramadol. materials and methods the analgesic activity was assessed by the acetic acid wri...

A method was developed for assessing ascorbic acid concentration in fruit juices and wine by differential pulse voltammetry. The oxidation peak for ascorbic acid occurs at about 530 mV (versus SCE) on a Pt strip working electrode and at about 470 mV on a carbon paste working electrode. The influence of the operational parameters like the pulse amplitude and the pulse period on the analytical si...

Juvenile shrimps (Penaeus monodon) weighing about 15-20 gms were procured from the grow-out ponds and reared under laboratory conditions. They were challenged with Vibrio parahaemolyticus MTCC 451 and their LD50 value was evaluated. The ascorbic acid and the histamine activity of both the control and experimental groups were assessed. The results showed a marked decline in both the parameters a...

although water and land pollution are very dangerous, air pollution has its own peculiarities due to its transboundary dispersion of pollutants over the entire world. in any well planned urban set up, industrial pollution takes a back seat and vehicular emissions take precedence as the major cause of urban air pollution. in the present study, air pollution tolerance index was calculated for var...

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%...
