Although the peel of the hallabong (Citrus sphaerocarpa) fruit is rich in polysaccharides, which are valuable dietary ingredients for human health, it is normally wasted. The present study aimed to utilize the peel waste and identify properties it may have against breast cancer metastasis. Hallabong peel extract containing crude polysaccharides was(More)
Existing influenza vaccines protect mostly homologous subtypes and acted most effectively only when well matched to the circulating strain. Immunization with an updated vaccine is therefore necessary to maintain long-term protection and the development of a broadly protective influenza vaccine against the threat of pandemic outbreak. The highly conserved(More)
Antitumor and immunomodulatory activities of an aqueous extract (GF100) of Acanthopanax senticosus were examined. In experimental lung metastasis of colon26-M3.1 carcinoma cells, intravenous (i.v.) administration of GF100 2 days before tumor inoculation significantly inhibited lung metastasis in a dose-dependent manner. The i.v. administration of GF100 also(More)
The objective of this study was to investigate the activation of natural killer (NK) cells and anticancer effects of exo-biopolymer from rice bran cultured with Lentinus edodes [rice bran exo-biopolymer (RBEP)]. Oral administration of RBEP induced the activation of NK cells in a dose-dependent manner. RBEP also prolonged the life spans of mice transplanted(More)
Ultraviolet B (UVB) irradiation may induce the acceleration of skin aging. The purpose of this study was to develop an effective formulation containing tannase-converted green tea extract (FTGE) to inhibit UVB-induced oxidative damage. Significant (p<0.05) prevention of the reduced form of glutathione (GSH) depletion was observed in mice treated with FTGE.(More)
BACKGROUND This study was performed to investigate the anti-wrinkle effects of topical applications of green tea extract with high antioxidant activity by tannase treatment. Increases in gallic acid (GA), (-)-epigallocatechin (EGC), and (-)-epicatechin (EC) were observed in the green tea extract after tannase treatment. OBJECTIVES This study was performed(More)
We investigated ginsenoside transformation by fermentation of red ginseng with Lactobacillus plantarum M-2. We also examined the anti-metastasis and immune-stimulating activities of EtOH extracts of fermented red ginseng (FRG-E) in animal and human subjects. Total sugar decreased from 85.5 mg mL(-1) to 44.1 mg mL(-1) with increasing culture time during the(More)
A polymerase chain reaction (PCR) assay for confirmation of Mycobacterium avium subsp. paratuberculosis was developed using the primer set derived from ISMav2. The PCR product was 494 base pairs (bp) and could be digested with ClaI, which produced 311- and 183-bp fragments. No amplification of 494-bp DNA fragment was detected from DNA of other Mycobacterium(More)
After we prepared exo-polymers (EPS) from Cordyceps sinensis by submerged culture, prophylactic intravenous administration (i.v.) of EPS significantly inhibited metastasis in experimental lung metastasis of colon 26-M3.1 carcinoma. Cytotoxicity against Yac-1 tumor cells of natural killer (NK) cell, which was prepared by i.v. of EPS (100 μg/mouse),(More)
Three genes encoding the secreted proteins (antigen 85-A, B, and C) of Mycobacterium avium subsp. paratuberculosis were cloned, sequenced and studied. The complete sequences of these three 85-complex proteins revealed their similarity with 85-complex proteins of other mycobacterial species. Specifically, these sequences showed 99% homology with M. avium(More)
