Studies on Organic Microanalysis. XIX

Studies on Copper Metabolism. Xix

Ferrokinetic studies were performed in three copper-deficient swine and the results have been compared with similar studies in 18 normal pigs. The mean value for the plasma iron turnover rate in the deficient swine was 1.76 mg./kg. day; for the red cell iron incorporation rate, 1.24 mg./kg. day; for the red cell iron turnover rate, 1.18 mg./kg. day; for the red cell life span, 13 days.

The Present Status of Organic Elemental Microanalysis

The influence of instrumental analysis, i.e., physicochemical methods, has become increasingly important in organic chemistry, but organic elemental microanalysis is by no means an obsolete field. On the contrary, with the development of new methods, the organic chemist obtains the results that he needs for a first orientation on a compound, more quickly and more reliably than ever before. Toda...

Studies of drugs given before anaesthesia. XIX. The opiates.

Using Ridit analysis, a comparison was made of the overall effects of what are generally considered to be equianalgesic doses of sixteen opiates, with respect to their desired and toxic effects when given as premedication to a standard population. Four mixtures of opiates, the non-opiate diazepam and saline were also included in the analysis. Results with all individual drugs have been previous...

Immunochemical studies of organ and tumor lipids . XIX . Cytolytic

Rabbit antisera to rat lymphosarcoma contain antibodies that are cytolytic for rat erythrocytes in the presence of complement. The reaction can be inhibited completely by pure cytolipin R showing that (u) immune hemolysis can be mediated through lipid determinants in the membrane, and ( b ) that cytolipin R determinants are present in the intact erythrocyte membrane and exposed on the surface. ...
