Separation of mitogenic fraction (PH-I) from Pseudostellaria heterophylla and characterization of its biological activities were investigated. PH-I was isolated as an alcohol-insoluble fraction from the hot water extract obtained by heating the roots of P. heterophylla in water at 80 degrees C for 4
Tumor necrosis factor (TNF) could be induced in the serum of ICR mice bearing Ehrlich ascites tumor (EAT) cells by the i.v. administration of antitumor fractions (PH-I A, PH-I B, PH-I C, PH-I Ca, PH-I Cb) separated from the roots of Pseudostellaria heterophylla. TNF could also be detected in the
We have previously shown that a mitogenic fraction (PH-I) separated from Pseudostellaria heterophylla (P. heterophylla) could act as a priming agent for the release of tumor necrosis factor-alpha (TNF-alpha) in mice. In the present study, PH-I was further purified by gel filtration chromatography
Pseudostellaria heterophylla has been becoming a popular research topic because of its functionally active components. The immunomodulatory activity of P. heterophylla peptide (PPH) derived from protein hydrolysate and the molecular mechanism underlying its immunomodulatory effect were investigated
Pseudostellaria heterophylla (PH) has various pharmacological effects that include immunologic enhancement and anti‑oxidation. However, it remains unclear whether PH exerts beneficial effects in dermatological diseases. The present study examined the effects of PH on a 2,4-dinitrochlorobenzene
Our previous study has demonstrated that Pseudostellaria heterophylla protein hydrolysate (PPH) has immunomodulatory activity on murine spleen lymphocytes. The aim of this study was to investigate the excitation of PPH in RAW264.7 macrophage cells and the protective effect in cyclophosphamide
