[Immunoturbidimetric determination of C-3 components of complement systems using nonlinear calibration].

A method for the immunoturbidimetric analysis of the C-3-component in the complement system was elaborated by means of the antiserum Q-SwAHu/C3 USOL (SEVAG) Praha. A diluted human control serum USOL (SEVAG) Praha with declared values of plasma proteins was applied as a standard solution. The relation between concentration and absorption in an eight step calibration series is well described by a parabola of the 2nd degree. The precision in series and the accuracy of the method are mentioned. The proposed technique is in a relatively good correlation with the radial immunodiffusion according to MANCINI.

Results of regular study on radionuclidic purity of 99mTc obtained from 99Mo--99mTc generators.

A total of 39 99mTc eluates obtained from 9 99Mo--99mTc generators delivered by The Radiochemical Centre Amersham during one year was studied with regard to their radionuclide purity. Using a Ge(Li) spectrometer the contaminants 60Co, 103Ru, 131I, 134Cs, 140Ba, 140La and 188Re were found in 99mTc-eluates with average levels ranging from 2.9 X 10(-3) to 2.8 X 10(-1) per cent of 99mTc activity. The additional total body absorbed dose caused by these contaminants, as calculated from their average content in 99mTc eluates, was less than 1% of the dose due to 99mTc pertechnetate.
