A mixture of a carhoxylic acid type of cation exchange resin and a weakly basic anion exchange resin has been used successfully to control the edema of 42 patients wvith congestive heart failure andl the ascites of 14 patients with cirrhosis of the liver. Approximately one-third of the cation exchanger was supplied in the potassium cycle. Inclusion of the anion exchange resin resulted in a grea...

Commercially available Diphonix(®) resin (TrisKem International) was evaluated as a receiving phase for use with the diffusive gradients in thin-films (DGT) passive sampler for measuring uranium. This resin has a high partition coefficient for actinides and is used in the nuclear industry. Other resins used as receiving phases with DGT for measuring uranium have been prone to saturation and sig...

The hyperthyroid state is associated with increased myocardial contractility. To clarify responsible mechanisms, we examined the effects of thyroid hormone on slow Ca channels, beta-adrenergic receptors, transsarcolemmal 45Ca flux and cytosolic free calcium in cultured chick ventricular cells. Compared with cells grown without triiodothyronine (T3), cells grown in 10 nM T3 possessed (a) 67% (P ...

The effects of thyroid hormone on guinea pig myocardial NaK-ATPase activity, transmembrane monovalent cation active transport, and cardiac glycoside binding were were examined. NaK-ATPase activities of left atrial and left ventricular homogenates of control and triiodothyronine (T3)-treated animals were determined, and compared to activities of skeletal muscle and liver. T3 administration was a...

The results of this study has revealed a significant increase in I(131) uptake of cultivated thyroid gland in the media containing petroleum ether extract of Commiphora mukul. Besides, T(3) resin uptake, protein bound iodine as well as free thyroxine index in the media are also observed to be significantly (P 0.001) increased. When explants are cultivated in the media containing melatonin, ther...

‘T”JiE ERYTHROCYTR UPTAKE of i’ -labeled triiodotlmyrornmme, first described by Hanuolsky et a!. (1), involves washmimig erythrocytes 5 times with 10-mi. volunies of saline. Renioval of these washes by decantation is tedious, tinue-consummiing, and liable to error. It was decided to design a maliifol(l which would remove 40 washes sinmultaneously, without any technical skill being required of t...

BACKGROUND This study evaluated the fluoride release and uptake of five common dental restoratives mainly glass ionomer formulations, including a conventional glass ionomer, a relatively new caries stabilization glass ionomer and resin-modified glass ionomer (Fuji II, Fuji VII and Fuji II LC); one compomer (F2000); and one fluoride releasing composite resin (tetric ceram). MATERIALS AND METHO...

Thyroid hormone lowers serum cholesterol and alters sterol metabolic processes. This laboratory has previously reported increased biliary lipid secretion as an early effect of triiodothyronine (T3) in the rat. To evaluate whether the bile lipid action of T3 is a primary or secondary effect, the isolated-perfused rat liver model was used. Red blood cells in lipid-free buffer were used to perfuse...
