[Seroepidemiology of varicella-zoster virus infection measured by the fluorescent antibody to membrane antigen test].

Objective: Adopting serology assay-fluorescent antibody to membrane antigen (FAMA) as "gold standard", sero-prevalence status of varicella-zoster virus (VZV) infection was investigated, in Guangzhou.

Methods: FAMA test was established with VZV infected human embryo fibroblasts as antigens and fluorescein isothiocyanate(FITC) labeled goat anti-human IgG as the secondary antibody. Sensitivity and specificity of the assay were evaluated.

[Determination of serum acute phase reaction protein in patients with severe acute respiratory syndrome].

Objective: To study the diagnostic value of determinations of serum acute phase reaction protein, such as complement 3 (C3), complement 4 (C4), prealbumin (PA) and C-reactive protein (CRP), etc., in patients with severe acute respiratory syndrome (SARS).

Methods: Serum levels of C3, C4, PA and CRP were determined by turbidimetry in 54 cases of SARS, 20 of other pneumonia and 30 normal persons.
