Discoloured Cholesterol and Wassermann Antigen
solid rectangles were yellow and in the debris were found yellow cylinders much smaller than the rectangles. The smell was suggestivje of bile salts. The fortifying effect of the sample on Jhe alcoholic heart extract, in the Wassermann reaction, was appreciably reduced. For the removal of the colour and smell the sample was submitted to four processes : (i) one gramme was subjected to negative ...
متن کاملAn investigation into the use of cardiolipin antigens. II. Complement-fixing properties of cardiolipin Wassermann antigen.
Complement-Fixing Properties of Cardiolipin This reagent was examined using two ranges of 0-6 per cent. to 0 0045 per cent. One range was suspended in saline at a dilution of 1 in 50 and the other at 1 in 200. No fixation of complement was obtained when using syphilitic sera. Mixtures of cardiolipin and lecithin were next tested for their complement-fixing ability in the presence of a suitable ...
متن کاملthe evaluation of language related engagment and task related engagment with the purpose of investigating the effect of metatalk and task typology
abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...
15 صفحه اولAn investigation into the use of cardiolipin antigens. III. Choice of a formula for cardiolipin Wassermann antigen for use in the Whitechapel Wassermann technique.
The choice of a formula for the antigen is limited by four considerations: (1) The anticomplementary action of the antigen. (2) The complement-fixing properties of the antigen. (3) The occurrence of floccules when the antigen is made in saline suspensions. (4) The unit strength of the formula to be employed. It has already been shown (Price, 1953a, b) that as far as the anticomplementary proper...
متن کاملThe Value of Diluted Antigen in the Wassermann Reaction.
This paper reports an attempt to assess the value of a modification of the Wassermann reaction wherein a suitable dilution of the normal antigen together with an increased amount of serum was used in an additional tube as suggested by Richardson (1940). By this method we hoped, first, to be able to differentiate specific reactions in sera giving doubtful results with the standard Wassermann tec...
