KOK has been widely taken as a traditional oriental medicine for improving blood circulation or age-related symptoms, such as(More)
Kyung-Ok-Ko (KOK), a well-known traditional Korean medicinal formula, has long been used to invigorate the essential qi. This use of KOK may be associated with reproductive ability as a more modern concept. The protective effect of KOK was evaluated against deterioration of testicular function induced by heat exposure in male mice. Male fertility was(More)
It was previously reported that polysaccharides (PL) isolated from Phellinus linteus strongly stimulated cell-mediated and humoral immunity. This study was undertaken to investigate the immunochemotherapeutic activity of PL against tumor growth and metastasis. PL alone significantly prolonged the survival rate of B16F10-implanted mice, inhibited tumor(More)
The carbohydrate-peptide linkage in acidic heteroglycopeptide from Phellinus linteus was characterized. Amino acid analysis showed large amounts of serine and threonine. Beta-Elimination results in the reduction of serine and threonine and a subsequent increase in alanine after reduction. These results indicated the presence of O-type linkage in the polymer.
Polysaccharide was purified from mycelial culture of Phellinus linteus (PL) and its effect on immunocompetence of normal splenocytes was observed. Overall in vitro immune function was enhanced by addition of PL into culture of mouse spleen lymphocyte and i.p. injection into mouse, while beta-glucans and other polysaccharides only raised the level of T(More)
