Interestingly, Danshen extract and its pure compounds showed different effectiveness in protecting HUVEC against Hcy-induced injury according to the following descending order: Dansen aqueous extract, 3-(3,4-dihydroxy-phenyl)-2-hydroxy-propionic acid, protocatechuic acid, catechin and protocatechualdehyde.

A panel study to evaluate quality of life assessments in patients suffering from allergic rhinitis after treatment with a Chinese herbal nasal drop
ARND may have a therapeutic effect by relieving clinical symptoms and improving the QOL in patients with perennial allergic rhinitis, with significant improvements in appetite and digestion after cross‐over treatment with ARND. Expand
Human papillomavirus infection in Macau women.
The HPV infection rate in Macau appears to be higher than that in the neighbouring city of Hong Kong, and the most prevalent genotypes were similar to those in South-west and Southern China. Expand
Studies of lymphocyte subpopulations and immunoglobulin production in IgA nephropathy.
The results failed to support a shift in the immuno-regulatory T lymphocyte subpopulations during clinical quiescence but a more profound defect in immunoregulation may probably occur during clinical exacerbation. Expand
Charge distribution of IgA-lambda in IgA nephropathy.
The data of raised anionic IgA lambda in IgA nephropathy may be important in determining its selective mesangial binding that could contribute to the immunopathogenesis. Expand
Light chain ratios of serum immunoglobulins in disease.
The kappa/lambda ratios of individual immunoglobulins in patients with rheumatoid arthritis, systemic lupus erythematosus and liver cirrhosis were similar to those of normal subjects, however, patients with IgA nephropathy displayed a distinctly lower IgA kappa-lambda ratio, suggesting a unique antibody response in the immunopathogenesis of this disease.

Predominant synthesis of IgA with lambda light chain in IgA nephropathy.
The results showed that patients with primary IgA nephropathy displayed a unique immunologic response characterized by a predominance of IgA with lambda light chain in circulation. Expand
Analysis of charge of kappa and lambda chain-containing serum immunoglobulin A by immunoblotting and densitometry.
A novel method for studying the charge distribution of different subclasses of serum immunoglobulin A (defined by the light chains) is described and developed membranes were made transparent with Triton-x 114 to obtain quantitation of charge distribution. Expand
Light-chain ratios of immunoglobulins G, A, and M determined by enzyme immunoassay.
An enzyme-linked immunosorbent assay for determination of light-chain ratios for IgG, IgA, and IgM in serum is described and kappa and lambda chain concentrations of individual immunoglobulins in the standard and samples are determined. Expand
High-performance liquid affinity chromatography for the purification of immunoglobulin A from human serum using jacalin.
A high-performance liquid affinity chromatographic method for the purification of serum immunoglobulin A (IgA) using a jacalin column is described and it showed that greater than 90% IgA could be recovered with less than 0.5% total IgG and greater than 2.0%total IgM remaining in the fractions containing purified IgA.
