Abstract A procedure for determining low levels of molybdenum in fertilizers by atomic absorption is proposed. With potassium thiocyanate as complexing agent, molybdenum is extracted in an isoamyl alcohol fraction to separate the fraction containing molybdenum from the water-soluble fraction containing materials that would interfere in the atomic absorption procedure. However, the procedure cannot be used with samples that have high concentrations of iron. Tests on the recovery of molybdenum in four fertilizers indicate that the procedure is reliable to levels as low as 2.5 ppm of molybdenum

Abstract A quantitative method is presented for the determination of cadmium at low levels (5–20 ppm) in water-soluble color additives by atomic absorption spectroscopy. Absorption measurements were made on aqueous solutions of typical color additives to which known amounts of cadmium had been added. The method requires no pretreatment of sample and should be applicable to all water-soluble color additives.

Abstract The stimulation by calcium and magnesium of ATPase activity of isolated ghosts, of water-soluble protein (spectrin), and of residual vesicles, derived from normal erythrocytes and from hereditary spherocytes (H.S.), has been measured. The ATPase activity found in normal water- soluble protein (WSP) at low levels of calcium (0.1–2.0 mM) is essentially absent in H.S. water-soluble protein, but the ATPase activity with magnesium and with high levels of calcium (60-100 mM) is the same in H.S. and normal WSP. Compared to normal, H.S. ghosts have increased Mg2+-stimulated activity. This increased activity is retained by the sedimentable vesicles (“residue”) after extraction of the ghosts with 0.025 mM EDTA. The Ca2+, Mg2+-ATPase associated with the calcium pump is not significantly different in H.S.

Low Levels

Since nutritional deficiencies might worsen the severity of symptoms and prolong the length of illness in non-nutritional disorders, particularly in the elderly, we examined the nutritional status of 216 elderly women newly admitted to a mental hospital. Compared to healthy elderly women, they had lower values for plasma prealbumin, vitamin C, and B vitamins. This was particularly common in senile dementia, and appeared to be the result of inadequate intake of protein or vitamins. Regular hospital diet for one month corrected the very low levels of prealbumin, but supplements were essential to remove deficiency of the water-soluble vitamins. Although vitamin supplements did not influence the length of stay in hospital, we did not exclude the possibility that nutritional deficiencies have a significant effect on the severity of mental illness.
