Effect of 1-alpha-hydroxycholecalciferol on magnesium metabolism in chronic renal failure Vitamin D derivatives and analogues are increasingly being used to treat bone disease in chronic renal failure but their effects on magnesium metabolism have not been fully documented. The use of 1-oc-hydroxycholecalciferol (1-m-OHDD) in chronic renal failure, however, may be associated with a special risk...
Properties of the rat hepatic cholecalciferol 25-hydroxylase have been studied. An assay system has been developed in which 25-hydroxycholecalciferol production is linear for at least 2h in both homogenates and microsomal fraction. Furthermore, the initial reaction velocity is linearly related to the amount of liver tissue or microsomal fraction. This enzyme system also metabolizes an analogue ...
Introduction: Contamination of etched enamel to saliva before placement of sealant prevents the appropriate bonding and results in microleakage. Using bondings is effective for decreasing the microleakage. This experimental study aimed to evaluate the effect of bonding agent on microleakage of a fissure sealant before or after contamination to saliva. Methods: In this experimental study 40 sou...
Background and Aim: At present, there are various methods for performing diagnostic tests. Due to the fact that saliva is easily available compared to other body fluids, it can be collected from patients in a non-invasive way and there is no risk of cross-infection because of it, so its use has become more common. Also, the analysis of substances in saliva can be a reflection of a person's oral...
statement of problem: amalgam is the most widely used dental restorative material. however, because of continuous low-level release of mercury from amalgam fillings, its safety has been questionable. purpose: the aim of this study was the evaluation of concentration of mercury in saliva before and after amalgam fillings and its relation with numbers and surfaces of amalgam fillings. materials a...
We describe a direct radioimmunoassay for cortisol in 10-microliter volumes of parotid saliva or whole saliva. Binding proteins are absent from these fluids, as demonstrated by the excellent correlation between results for samples assayed directly and by a comparison procedure involving extraction with 1,2-dichloroethane. The direct assay is specific, precise, and had a lower limit of sensitivi...
the aim of this study was to investigate the rheological behavior and mucoadhesive nature of saliva substitutes, by incorporating various mucoadhesive polymers into an artificial saliva pump spray formulation. for this purpose various mucoadhesive polymers including cellulosic polymers in the range of 0.1-1.0% and carbomers such as c974p, c971, c934p and c971 in the range of 0.01-0.1% were adde...
We report here the first radioimmunoassay for a vitamin D metabolite utilizing a radioiodinated tracer. Antibodies were generated in a goat immunized with the vitamin D analog 23, 24, 25, 26, 27-pentanor-C(22)-carboxylic acid of vitamin D, coupled directly with bovine serum albumin. The 125I-labeled tracer was prepared by reacting a 3-amino-propyl derivative of vitamin D-C(22)-amide with Bolton...
