Cd-EGTA和La-EGTA的DNMR谱

Biocompatibility of EDTA, EGTA and citric acid.

This in vivo study evaluated, through the physicochemical assay method for quantification of enhanced vascular permeability, the irritating potential of EDTA, EGTA, citric acid and saline. Thirty-two male Wister rats were anesthetized and four experimental sites were demarcated on their backs. Injections of 2% Evans blue (20 mg/kg) were administered intravenously into the lateral caudal vein. T...

Thyrocalcitonin, EGTA, and urinary electrolyte excretion.

The infusion of thyrocalcitonin (TCT) into thyroparathyroidectomized rats, given either no exogenous parathyroid hormone or a constant infusion of this hormone, leads to a transient phosphaturia and a decreased excretion of urinary magnesium, calcium, and hydroxyproline without a change in glomerular filtration rate. The changes in phosphate excretion may be due to a direct effect of the hormon...

The effects of EDTA and EGTA on renin secretion.

1 The effects of the disodium salt of ethylenediamine tetra-acetate (EDTA) and 1, 2, bis, 2 aminoethoxyethane-NNN'N'-tetra-acetic acid (EGTA) on renin secretion and vascular resistance were studied in the isolated perfused kidney of the rat. 2 Both substances produced a significant increase of renin release 3 In the absence of calcium and magnesium, EDTA still increased rein release and there w...

Effect of different EGTA concentrations on dentin microhardness.

The effect of 1%, 3% and 5% EGTA (ethylene glycol-bis-(beta-amino-ethyl ether) N,N,N',N'-tetra-acetic acid) on the microhardness of root dentin of the cervical third of human teeth was studied. Five newly extracted maxillary incisors were sectioned transversely at the cementoenamel junction, and the crowns were discarded. The roots were embedded in blocks of high-speed polymerized acrylic resin...
