the ability to biosynthesis of protein A from some Staphylococcus aureus strains isolated from the patients of Bach Mai Hospital was studied in the years 2001-2002. The results showed that there were 3 strains (25, 28 and 55) have the ability to synthesize protein A in the highest levels among 8 strains investigated. Using ELISA technique with protein A served as an antigen from Staphylococcus strain 25 to analyse IgG from sera of 32 healthy subjects has determined that the average IgG level from human serum is 14.37mg/ml. This result was supported by the same technique using commercial foreign bio-kit. It is proven that protein A preparation can be used as an antigen in bio-kit capturing specifically IgG from human serum in clinical diagnosis and in immuno-pathological research using ELISA technique

OBJECTIVE: To investigate how many leiomyoma patients are exposed to bisphenol-A (BPA) and whether the serum concentration of BPA is related to leiomyoma growth. METHODS: Total 131 patients were recruited for measuring BPA. Initially, leiomyoma patients were divided into three groups, mild (n=38), moderate (n=33), and severe (n=30) according to the size of the leiomyomas. The control (n=30) group was defined as having no leiomyomas. The identification and diameter measurements of leiomyomas was performed by transvaginal ultrasonography. Serum BPA concentrations were measured by enzyme linked immunosorbent assay. RESULTS: BPA was detected in 83.9% out of 131 samples totally, and 83.1% out of 101 leiomyoma patients. In detail, the detection rates of serum BPA were 86.7% in control group, 71.1% in mild group, 84.9% in moderate group, and 96.7% in severe group. The mean BPA concentrations in the control group was 0.557+/-0.086 ng/mL and those in the leiomyoma groups were 0.273+/-0.052 ng/mL (mild), 0.336+/-0.063 ng/mL (moderate), and 0.636+/-0.075 ng/mL (severe) (P=0.0003). Values are mean+/-standard error. Conclusions: The detection rate of serum BPA in control and leiomyoma groups were 86.7% and 83.1% respectively. However, there was no statistical significance of serum BPA concentrations between control and leiomyoma groups. To verify the effect of BPA on the leiomyoma growth, close and sequential monitoring for the person who have exposure risk is recommended.

Assessing antigen concentration of vaccine is essential step in determining the quality of the vaccine prior to vaccination. After vaccination, vaccine-induced antibody titer should also be measured to verify the vaccine efficacy. Since conventional assay used for vaccine concentrations and induced Ab-titers is antibody-based enzyme-linked immunosorbent assay, the assay inevitably brings drawbacks of antibody such as high cost for production, limited stability, and inconsistent quality between lot-to-lots. Aptamer is single-stranded nucleic acid having three-dimensional structure and has features overcoming limitations of antibody. This review will briefly introduce the features of aptamer and potential of aptamer-based system for evaluation of vaccine efficacy.
