Standardization of the Wassermann Test using Preserved Complement Titrated to 50 per cent. Haemolysis

Standardization of the Wassermann test using preserved complement titrated to 50 per cent haemolysis.

This paper describes a modification of the Wassermann test giving an improved standardization of the complement titration and of the haemolytic system which is suitable to the resources of a small laboratory. Advantage has been taken of the stability of complement preserved by the method of Richardson (1941), so that modern methods for the standardization of the haemolytic system can be include...

Automation of the Wassermann complement-fixation test using a discrete analyser.

Anaesthesia for Caesarean section. Analysis of blood concentrations of methoxyflurane using 0.1 per cent methoxyflurane and 40 per cent oxygen.

In fifteen mothers undergoing elective Caesarean section methoxyflurane 0.1 per cent vapour was added before the birth of the infant to a mixture of 40 per cent oxygen and 60 per cent nitrous oxide. Analysis of uptake and excretion of methoxyflurane was performed. Prompt recovery of consciousness occurred at the end of the procedure. In none of the mothers was there evidence of awareness during...

An examination of the treponemal Wassermann reaction and Reiter protein complement-fixation test.

Less than one year after the description of the Treponema pallidum by Schaudinn and Hoffman, the first report of the application of the complementfixation reaction of Bordet and Gengou (1901) to the diagnosis of human syphilis was published in Budapest by Detre (1906), exactly 2 weeks after the appearance of the classical paper "A Sero-diagnostic Reaction in Syphilis" by Wassermann, Neisser, an...

Different Amounts of Transformed Atoxyl Produced by Incubating One per Cent. and Ten per Cent. Atoxyl in Blood

1. 10 per cent. atoxyl in blood incubated at 37 degrees C. for 1 hour gives rise to a solution that is much more than ten times as toxic as a 1 per cent. solution of atoxyl similarly incubated. 2. When the comparison is made after incubation for 3 hours instead of for 1 hour, the toxicity of the 10 per cent. solution is but slightly greater than ten times that of the 1 per cent., provided the r...
