Conducting pr

The complexes of some rare earths with DL-2-amino-n-butyric acid were synthesized. The solid complexes have the general formula [Ln(Hbu)4]Cl3 [Ln: Pr, Nd, Sm, Eu, Gd and Hbu: CH3CH2CHNH2COOH]. The structure of the complexes have been recognised by the basic of elemental analysis, conductivity measurements, IR spectra and thermal analysis methods. It was found that the DL-2-amino-n-buryic acid utilized amino nitrogen and carboxyl oxygen for bonding.

Diagnostic Tests The choice of diagnostic tests should be guided by the history and the physical examination. Measurements of serum electrolytes, glucose, and the hematocrit are usually indicated. Cardiac enzymes should be evaluated if myocardial ischemia is suspected. Blood and urine toxicology screens may reveal the presence of alcohol or other drugs. In patients with possible adrenocortical insufficiency, plasma aldosterone and mineralocorticoid levels should be obtained.
