Improved Quantitation of Cephalin-cholesterol Flocculation Test.
A rapid turbidimetric method for the determination of cephalin-cholesterol flocculation is described. Greater specificity and photometric sensitivity have been achieved along with adequate precision. The test is standardized with the conventionalbarium sulfate turbidity standards usedfor other laboratory procedures. Definition of results in turbidity units is proposed, and photometric standardi...
متن کاملMechanism of the Positive Cephalin-cholesterol Flocculation Reaction in Hepatitis.
An alteration of the blood serum proteins in patients with catarrhal jaundice has been amply established by the development of a positive cephalin flocculation (1). A standard emulsion composed of cephalin and cholesterol, which remains stable in 0.2 ml. to 0.1 ml. normal serum, diluted 1: 21, tends to flocculate and precipitate when added under identical conditions to the serum of patients wit...
متن کاملY Serial Cephalin Flocculation Test in Leprosy a Preliminary Report
In 1943 Bruger (1) proposed a fractional cephalin-cholesterol flocculation test to be used as an index of increasing or decreasing hepatic dysfunction. This modified test consisted in the use of increasing dilutions of serum with saline, noting the flocculation according to the procedure originally described by Hanger. The data presented in support of the modified test do show that, when it is ...
متن کاملSignificance of Cephalin-cholesterol Flocculation Test
The effect of malarial fever on hepatic physiology has recently been investigated. It has been found (1) that considerable bromsulphthalein retention, a marked reduction in cholesterol and cholesterol esters, a moderate fall in phospholipids, diminished hippuric acid excretion and a strongly positive cephalin-cholesterol flocculation reaction resulted when malaria was induced in 9 patients by i...
متن کاملA Rapid Modification of the Cephalin Cholesterol Flocculation Test.
‘THE LENGTHY INCUBATION PERIOD and the subjective interpretation of degree of flocculation ai’e undesirable characteristics of the Hanger cephalin cholesterol flocculatiomi test (1). Several workers (2-4) have reported modifications either to shorten test time or to determine extent of flocculation mnstrumemitally. Inadequate sensitivity has been noted in some of these technics as well as inter...
