abstract background and aim: reduction of dental plaque ph is an effective factor in the incidence of dental caries. one of the common methods for assessment of the cariogenic potential of food products is the study of plaque ph changes in the oral environment. the present study was performed due to the importance of dental plaque and its known complications and also the increase in consumption...

background the increase in intestinal permeability following damage to the intestinal mucosa in any surgical procedure, trauma or fasting is well- known. objectives our objective was to experimentally evaluate whether antioxidant consumption is associated with decreased intestinal damage in intestinal surgical procedures. materials and methods forty rabbits were used to compare the pathological...

this study was designed to investigate the effects of tangerine, orange, and grapefruit juice on the pharmacokinetic pattern of cyclosporine a in rats. forty male sprague-dawley rats were divided into four groups to receive water, orange, tangerine, or grapefruit juices respectively. water or juices (10 ml/kg) were given orally twice a day for 3 days. three hours after the 5 th dose, cyclospori...

Orange juice concentrates were packaged aseptically by a “Dole” aseptic canning machine using 6 oz metal cans. The final juice products (ll”, 34’, 44’, 58” Brix) were stored between -18” and 36°C and tested periodically for nonenzymatic browning, ascorbic acid destruction, furfural and sensory changes. Nonenzymatic browning, the main deterioration phenomena in these products, was satisfactorily...

Oregano has been shown to possess antioxidant capacity in various in vitro models and has thus been suggested to be potentially beneficial to human health, but studies in humans are lacking. The aim of this study was to investigate the bioavailability and the effects of Origanum vulgare extract supplementation on serum lipids and lipid peroxidation in healthy nonsmoking men. A four-week double-...

OBJECTIVES To assess the erosive potential of a number of readily available flavoured waters in the laboratory. METHODS The erosive potential was assessed by measuring the pH, neutralisable acidity and ability to erode enamel. These were compared to an orange juice positive control. RESULTS The pH of the flavoured waters ranged from 2.64-3.24 with their neutralisable acidity ranging from 4....

The aim of this study was to compare tooth surface pH after drinking orange juice or water in 39 patients with dental erosion and in 17 controls. The following investigations were carried out: measurement of pH values on selected tooth surfaces after ingestion of orange juice followed by ingestion of water (acid clearance), measurement of salivary flow rate and buffering capacity. Compared with...

BACKGROUND We previously established furanocoumarins as mediators of the interaction between grapefruit juice (GFJ) and the model CYP3A4 substrate felodipine in healthy volunteers using a GFJ devoid of furanocoumarins. It remains unclear whether furanocoumarins mediate drug-GFJ interactions involving CYP3A4 substrates that are also P-glycoprotein substrates. OBJECTIVE The effects of furanocou...

Glyphosate is a broad spectrum herbicide. Fruits and vegetables improve health and a diminish chronic degenerative processes. This study aims to investigate orange juice protective role against the toxicity of glyphosate induced in mice. Fifty six adult male albino mice divided into seven groups. Oral administration of glyphosate caused a significant increase in MDA levels, serum AST, ALT, BUN,...
