Hemagglutination-inhibition test in rhinovirus infections of volunteers.
The hemagglutination-inhibition (HI) test for antirhinovirus antibody was carried out on paired sera from volunteers inoculated with rhinovirus type 3 or type 4 (RV4). The HI test gave results which paralleled the neutralization test and was at least as sensitive as a microneutralization method for detection of serotype-specific antibody. Although high levels of HI antibody in the serum were as...
متن کاملEffect of induced interferon in experimental rhinovirus infections in volunteers.
Nasal administration of an interferon inducer, CP-20,961 (N, N-dioctadecyl-N', N'-bis(2-hydroxyethyl)propanediamine), was evaluated in a double-blind, placebo-controlled study of experimental rhinovirus infection in 29 volunteers. Detectable nasal interferon developed in 10 of 15 subjects treated with CP-20,961, and 2 of 14 in the group receiving placebo (P < 0.006). Titers of CP-20,961-induced...
متن کاملPreparation of an Inactivated Egg Drop Syndrome Antigen for Using in Hemagglutination Inhibition Test.
To prepare hemagglutination inhibition (HI) antigen the egg drop syndrome virus (EDSV) was propagated in 10-day-old embryonated duck eggs. The virus antigen was inactivated with two methods including heating (65°C) and adding 0.5% formaldehyde by considering low destroying effect on hemagglutination (HA) and HI titers. The EDSV HI titers of 310 sera and 100 yolks obtained from 23 chicken farms ...
متن کاملExperimental rhinovirus infection in volunteers.
Experimental viral disease studies in volunteers have clarified many aspects of the pathogenesis of human viral disease. Recently, interest has focused on rhinovirus-associated asthma exacerbations, and new volunteer studies have suggested that airway responsiveness (AR) is enhanced during a cold. For scientific, ethical and safety reasons, it is important to use validated methods for the prepa...
متن کاملSimple hemagglutination inhibition test for the diagnosis of toxoplasmosis.
A simple hemagglutination inhibition (HI) test for the serological diagnosis of toxoplasmosis has been developed and evaluated. A total of 84 human and 120 mouse serum samples were tested by the newly developed HI test and compared with an immunoglobulin G-indirect fluorescent antibody test. Statistical analysis of serum titers obtained by using the HI test and the immunoglobulin G-indirect flu...
