In our hands precipitation (Clark & Colip, 1925) and visual complexometric (Buckley, Gibson & Bortolotti, 1951) methods of determining calcium and magnesium in blood serum have proved difficult for routine diagnostic purposes. The ammonium oxalate-ammonium phosphate method tended to give difficulty with the precipitates. The end point of the complexometric method varied with operators and even ...
Eyes are supplied O2 through the cornea and vessels of the retina and iris, which are tissues characterized by aerobic metabolism. Meanwhile, there are no reports on the association between iris sphincter contraction and aerobic metabolism. In this paper, we studied the aforementioned association. Eyes from adult pigs of either sex were obtained from a local abattoir. A muscle strip was connect...
Apart from the breast milk, infant formula and baby weaning food have a special role in infant diet. Infants and young children are very susceptible to amount of trace elements. Copper and zinc are two elements that add in infant food. Lead and cadmium are heavy metals that enter to food chain unavoidably. DPASV is a benefit and applicable method for measurement of trace elements in food produc...
The urinary excretion of cystine, as determined on the polarograph, varies, in normal adults, between 40 and 80 mg. daily (1). It may be increased either as a result of a low renal threshold for cystine or a raised plasma cystine concentration. Cystinuria due to a low renal threshold occurs in 'classical cystinuria,' the Fanconi syndrome and hepatolenticular degeneration (2). In such conditions...
