Solutions in contact with polyvinyl chloride can become contaminated with trace amounts of lead, titanium, tin, zinc, iron, magnesium or cadmium from additives used in the manufacture and moulding of PVC. V-Phenyl-2-naphthylamine is a contaminant of solvents and biological materials that have been in contact with black rubber or neoprene (in which it is used as an antioxidant). Although it was only an artefact of the separation procedure it has been isolated as an apparent component of vitamin K preparations, extracts of plant lipids, algae, livers, butter, eye tissue and kidney tissue [Brown Chem Br 3 524 1967]. 

Nitrogen sources include proteins, such as casein, zein, lactalbumin protein hydrolyzates such proteoses, peptones, peptides, and commercially available materials, such as N-Z Amine which is understood to be a casein hydrolyzate also corn steep liquor, soybean meal, gluten, cottonseed meal, fish meal, meat extracts, stick liquor, liver cake, yeast extracts and distillers solubles amino acids, urea, ammonium and nitrate salts. Such inorganic elements as sodium, potassium, calcium and magnesium and chlorides, sulfates, phosphates and combinations of these anions and cations in the form of mineral salts may be advantageously used in the fermentation. 

Concentration limits for chloride and acetate in PN typically are linked to limitations for sodium and potassium. The usual ratio of chloride acetate in PN is about 1 1 to 1.5 1. Chloride and acetate primarily play a role in acid-base balance. Acetate is converted to bicarbonate at a 1 1 molar ratio. This conversion appears to occur mostly outside the liver. Bicarbonate never should be added to or coinfused with PN solutions. This can lead to the release of carbon dioxide and potentially result in the formation of calcium or magnesium carbonate (very insoluble salts). 

Liver function, including AST, ALT, alkaline phosphatase, lactate dehydrogenase (LDH), total and conjugated bilirubin a comprehensive metabolic panel can be ordered (i.e., sodium, potassium, chloride, bicarbonate, blood urea nitrogen, creatinine, glucose, calcium, AST, ALT, alkaline phosphatase, albumin, and total bilirubin), but phosphorus, magnesium, and fractionated... 

Signs of chronic zinc poisoning evident after 12-14 months. Signs included reduced appetite, emaciation, submandibular edema, diarrhea, moderate anemia, elevated serum zinc (4.3-6.0 mg/L vs. normal 1.8-2.1), liver Zn (420-1600 mg/kg DW vs. normal 72-248), kidney Zn (910-1680 mg/kg DW vs. normal 40-114), and low serum calcium and magnesium.

Monitoring Monitor renal function frequently during amphotericin B therapy. It is also advisable to monitor liver function, serum electrolytes (particularly magnesium and potassium), blood counts, and hemoglobin concentrations on a regular basis. Use laboratory test results as a guide to subsequent dose adjustments. Monitor complete blood count and prothrombin time as medically indicated.

Protein or calcium deficiency impairs drug metabolism in animals, due to decreased activity of the microsomal enzymes of the liver. The sleeping time by hexobarbitone is increased as a result of prolonged protein malnutrition. Acetylsalicylic acid has been shown to be more toxic to animals on a diet deficient in protein and magnesium.

Niwaguchi et al. (14-16) reported that when rat liver homogenates were incubated in a system containing 14C-L-glutamate, glucose, DPN, adenosine triphosphate (ATP), magnesium ions, cytochrome c, and fu-marate, an acidic compound was formed which could be identified as pyrrolidone carboxylic acid by infrared spectroscopy, electrophoresis,... 

An alkaline pyrophosphatase from rat liver cytoplasm has been partially purified and characterized (24) the corresponding enzyme from mice is inhibited by Mg J+-ADP and free PPj, and free Mg2+ has been implicated as an allosteric activator (23). Partial heat inactivation results in loss of the apparent allosteric effects. Rat liver mitochondrial pyrophosphatase, which is inhibited by adenine nucleotides (36), appears to be bound to the inside of the inner mitochondrial membrane (37). This enzyme, after solubilization, has been separated into two fractions which have somewhat different specificity (24, 38). A pyrophosphatase strongly simulated by sulfhydryl reagents (39) has been partially purified from brain tissue (40). The mono-magnesium PPj complex appears to be the true substrate for this enzyme (41). Pynes and Younathan have purified a pyrophosphatase 1800-fold from human erythrocytes (43). The properties of this enzyme are strikingly similar to those of the yeast enzyme the major difference appears to be the more rigid substrate specificity of the erythrocyte enzyme in the presence of Znz. ...
