Equal weights of the various protein fractions in plasma affect the plasma specific gravity equally, whereas weight for weight the fractions exert differing influences on the plasma viscosity. Thus fibrinogen has a greater effect on the plasma viscosity than does globulin, which, in turn, has a greater effect than albumin (Bircher, 1921 ; Naegeli, 1931; Oberst, 1939; Cowan and Harkness, 1947). ...

We found the Easy very easy to run and without te#{233}hnique-dependent steps in the procedure. Operators need not have a high level of skill. Calibration is stable for one month, except for the ion-selective electrodes, which must be calibrated every two days. In conclusion, we found the Easy satisfactory in operational and analytical performance. The analyzer is well suited for use in the eme...

HIS STUDY WAS UNDERTAKEN IN AN ATTEMPT to evaluate some of the more promising methods for the determination of cerebrospinal fluid protein with the objective of deciding on the most suitable one for use in this laboratory. There are a number of methods available, with great variations in the ease of performance and the accuracy of results; therefore it seems that some sort of compromise must be...

In the title compound, [Gd(C(2)H(5)N(3)O(2))(2)(H(2)O)(4)]Cl(3), which is isostrucutural with its yttrium analogue, the Gd(3+) ion (site symmetry 2) is bonded to eight O atoms (arising from two O,O'-bidentate biuret mol-ecules and four water mol-ecules) in a distorted square-anti-prismatic arrangement. A network of N-H⋯O, N-H⋯Cl and O-H⋯Cl hydrogen bonds helps to establish the packing, leading ...

Variation of the protein content in urine of patients known to excrete protein in excessiveamountswas studied. Variation in different specimensobtained from the same patient on a particular day and from day to day were studied. A total of 293 urine specimensexcreted over a 3to 6-day period by 25 patients were examined. No particular pattern of protein excretion was observed. The morning specime...

Recent interest in the treatment of disseminated intravascular coagulation with heparin (1, 2) has caused some clinicians and laboratory workers to express doubt concerning the accuracy of fibrinogen methods based on thrombin-induced fibrin clot formation and subsequent measurement of the fibrin by biuret methods. It was reasoned that inaccurately low results would be produced owing to the pres...

IN THE TITLE COMPOUND (SYSTEMATIC NAME {[(phenyl-formamido)-carbon-yl]amino}-methane-thio-amide), C9H9N3O2S, both benzoyl and terminal thio-urea fragments adopt transoid conformations with respect to the central carbonyl O atom. The benzoyl and thio-biuret groups are almost coplanar, making a dihedral angle of 4.40 (8)°. The mol-ecular structure is stabilized by two intra-molecular N-H⋯O hydrog...
