Randomized Controlled Trial
Effects of So-cheong-ryong-tang and Yeon-gyo-pae-dok-san on the common cold: randomized, double blind, placebo controlled trial.
So-cheong-ryong-tang (SCRT) and Yeon-gyo-pae-dok-san (YPS) extracts are widely used in treatment of the common cold. The purpose of this study is to evaluate the efficacy of SCRT and YPS on the common cold. ⋯ SCRT and YPS have beneficial, albeit limited, effects on common cold patients, especially those with the Wind-cold pattern cold.

Lonicera japonica Thunb and Anemarrhena asphodeloides BUNGE have been used for the treatment of a variety of inflammatory diseases, cold and infective diseases in many countries, including Korea and China. ⋯ When compared to celecoxib, WIN-34B exhibited similar or better anti-nociceptive and anti-inflammatory activities in osteoarthritic animal models, which may become a potential novel treatment for osteoarthritis.

Lubricating gut pill (LGP), a traditional Chinese formula, was widely used for the treatment of chronic constipation, especially in the elderly, in China. However, it is unclear whether LGP-induced laxative and/or lubricating effect is involved in water and electrolytes transport in distal colonic epithelium. ⋯ LGP enhances Cl(-) secretion that is mostly mediated through the release of cyclooxygenase metabolites, by which provided an osmotic force for the subsequent laxative action observed in the rat constipation model.

Comparative Study
Pharmacokinetic properties of paeoniflorin, albiflorin and oxypaeoniflorin after oral gavage of extracts of Radix Paeoniae Rubra and Radix Paeoniae Alba in rats.
To establish a HPLC-MS method and investigate the pharmacokinetic properties of paeoniflorin, albiflorin and oxypaeoniflorin and the pharmacokinetics difference of Radix Paeoniae Rubra and Radix Paeoniae Alba. ⋯ A specific and sensitive HPLC-ESI-MS method was developed for simultaneous determination of paeoniflorin, albiflorin and oxypaeoniflorin in rat plasma and was successfully applied to pharmacokinetic study. The results might be helpful for the investigation of different effects of Radix Paeoniae Rubra and Radix Paeoniae Alba.

Rhizoma coptidis is used widely in traditional Oriental medicine to treat inflammatory diseases. The aim of this study was to identify the anti-inflammatory target genes of Rhizoma coptidis extract (CEX) in lipopolysaccharide (LPS)-stimulated RAW264.7 murine macrophage-like cells. ⋯ The data obtained in this study demonstrate that CEX exerts its anti-inflammatory effect by inhibiting the expression of various proinflammatory cytokines and cell surface molecules involved in inflammatory responses at the transcriptional level. These data support the traditional use of CEX as an anti-inflammatory agent and should provide useful information for the understanding of the pharmacological effects of CEX.
