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 ...

laboratory diagnostic tests are useful in diagnosis of hydatidosis of the lung. in this study, we compare the diagnostic values of these immunodiagnostic tests with the clinical evidence of hydatid disease. application of these tests, especially indirect hemagglutination and bentonite flocculation, is shown to be very useful in diagnosis of the disease, of course in combination with clinical fi...

In an earlier paper in this Journal (Vogelsang, 1947), a new microflocculation test for syphilis described by Harris, Rosenberg, and Riedel (1946) was compared with the Wassermann reaction, the Kahn standard test, and the Meinicke clarification test in 5,556 sera. The test was found to be very useful in the diagnosis of syphilis, having a satisfactory sensitivity and a good specificity. Harris ...

The high volume and unfavorable properties of high-water-content slurries make their treatment difficult costly. Improving the through prefabricated drains combined with surcharge or vacuum preloading represents an environmental economic means reusing these as subsoil. As conventional methods are inefficient in dealing low-permeability slurries, flocculation is often applied. In this study, inf...

During the past few decades many flocculation tests have been developed for use in the serological diagnosis of syphilis. Of these the one most widely used at the present time is the Venereal Disease Research Laboratory (VDRL) test, described by Harris, Rosenberg, and Riedel (1946) and Harris, Rosenberg, and Del Vecchio (1948) and named after the laboratory in which it was developed. The VDRL t...

In a previous paper, Tringali, Del Carpio, and Gismmanco (1966) reported that treatment of sera with 2-Mercaptoethanol (2-ME) caused a disappearance of non-syphilitic anticardiolipin reactivity, usually referred to as T'false positive" (EP) reactivity, as detected in a complement-fixation assay, However, similar treatment did not abolish the reactivity of syphilitic sera in the samie assay. Thi...

Most of the tests of liver function normally performed in a routine laboratory depend on quantitative and qualitative changes in the serum proteins. Since it is now well established that the serum protein pattern in Africans differs significantly from that generally accepted as normal for Europeans (Arens and Brock, 1954; Edozien, 1957; Holmes, Stanier, Semambo, and Jones, 1951 ; Schofield, 195...
