in this study, the effects of dietary egg lecithin on digestive enzymes and body biochemical composition of juveniles mesopotamichthys sharpeyi was evaluated. four experimental diets including control diet (with 0% egg lecithin) and three diets containing 2%, 4% and 6% egg lecithin were used. at the end of the experiment, digestive enzymes activity (lipase, amylase and alkaline phosphatase) and...

screening of3000 soil samples collected from cities of four different provinces of iran for starch-hydrolysing bacteria revealed that the nature is enriched with streptomyces species capable of producing amylolytic enzymes. among the bacterial isolates, one of the high starch-degrading strains was selected for further microbiological identification and also amylolytic enzyme(s) characterization...

bioactive food components (such as phenolic compounds, carotenoids, anthocyanins, tochopherols, ascorbic acid, flavonoids, minerals, enzymes and pectin) are active ingredients in food or dietary supplements, which proven to have an important role in health, and are safe for human consumption. these compounds exert their antioxidant effects by different mechanisms such as single electron transfe...

All five urea cycle enzymes of rat liver increased in activity 48 h after subcutaneous administration of crystalline zinc glucagon to male rats and remained elevated after 7 days of continuous glucagon infusion. The maximum ratios of enzyme activities over those of controls were 2.0 for carbamyl phosphate synthetase, 1.3 for ornithine transcarbamylase, 2.7 for argininosuccinate synthetase, 3.2 ...

Background: Organic acids and their salts are known as appropriate substitutes in feed for improving the health, growth, performance of fish. Objectives: The present study was conducted to determine effects dietary lactic acid supplementation on immunological factors, hepatic enzyme activity, plasma proteins common carp, Cyprinus carpio. fish were fed diets mentioned above 56 days, then growth ...

SEVERAL YEARS AGO LaDue (2) made the iiiteresting observation that soon after myocardial infarction the plasma glutamic oxalacetie tramisammase is increased, reaches a peak within a few days, and then returns to normal. This observation stimulated a new area of clinical interest ill diseases related to infarction and necrosis as manifested ill plasma enzymes changes. The source of this increase...

The sites of reaction product resulting from ATPase and 5-nucleotidase activities remaining in parenchymatous cells of osmium-fixed rat liver were studied by electron microscopy of thin sections. These indicate that both ATPase and 5-nucleotidase activities are localized in the plasma membrane where it folds to form the microvilli of the bile canaliculus, and that 5-nucleotidase activity is als...

Bergamottin, a furanocoumarin isolated from grapefruit juice, was investigated for the ability to increase diazepam bioavailability and for its effect on cytochrome P450 (P450) enzymes in the beagle dog liver and intestine. To study the effect of bergamottin on diazepam pharmacokinetics, male beagle dogs were dosed with bergamottin (1 mg/kg) p.o. 0 or 2 h before p.o. diazepam (10 mg). In a seco...
