ABSTRACT:

FIELD OF THE INVENTION
The invention relates to compositions that are beneficial for the liver and useful as dietary supplements. These compositions contain yeast cells obtainable by growth in electromagnetic fields with specific frequencies and field strengths.
BACKGROUND OF THE INVENTION
There are various types of liver diseases, including acute hepatitis, chronic hepatitis, toxic liver injury, hepatic cancer, cirrhotic liver, fatty liver, portal hypertension, and the like. Liver disease in some patients develops into hepatic cirrhosis or even hepatic cancer after a period of time (A report by the research group on liver diseases, Health and Welfare Ministry, 1979). Prevention, observation, and cure of hepatitis are therefore important for preventing cirrhotic liver and hepatic cancer. In recent years, animal models of hepatitis and hepatic cancers have been developed and their application to the research of liver diseases is ongoing (Mori et al.,
Hepatic, Cholecyst, Pancresto
19(5):905-910 (1989)).
Rest and diet are principal means for curing acute hepatitis, while various other measures are taken to cure active-type chronic hepatitis, especially hepatitis B. Interferon, adenine arabinoside, and acyclovir have been used to treat hepatitis. However, prolonged use of these drugs causes severe side effects. Development of a treatment that is safe and effective for treating liver diseases is therefore strongly desired.
SUMMARY OF THE INVENTION
This invention is based on the discovery that certain yeast cells can be activated by electromagnetic fields having specific frequencies and field strengths to produce substances that are beneficial for the liver. Compositions comprising these activated yeast cells can be used as dietary supplements for improving liver health, e.g., alleviating symptoms of hepatitis, cirrhosis, fatty liver and other liver ailments.
This invention embraces a composition comprising a plurality of yeast cells that have been cultured in an alternating electric field having a frequency in the range of about 18000-18500 MHZ (e.g., 18180-18240 MHz), and a field intensity in the range of about 50 to 500 mV/cm (e.g., 100-450 mV/cm). The yeast cells are cultured in the alternating electric field for a period of time sufficient to substantially increase the capability of said plurality of yeast cells to produce substances beneficial for the liver. For instance, the cultured yeast cells when ingested can normalize the level of serum glutamate-pyruvate Transaminase (GPT), alkaline phosphatase (AP), and/or lactate dehydrogenase 5 (LDH-5) in a mammal.
The term “normalize” means changing the level of abnormally high or low concentrations of subject proteins in a mammal to a substantially normal level.
In one embodiment, the frequency and/or the field strength of the alternating electric field can be altered within the aforementioned ranges during said period of time. In other words, the yeast cells can be exposed to a series of electromagnetic fields. An exemplary period of time is about 40-100 hours (e.g., 50 to 80 hours).
Yeast cells that can be included in this composition can all be obtained from the China General Microbiological Culture Collection Center (“CGMCC”), a depository recognized under the Budapest Treaty (China Committee for Culture Collection of Microorganisms, Institute of Microbiology, Chinese Academy of Sciences, Haidian, P.O. BOX 2714, Beijing, 100080, China). Useful yeast species include, but are not limited to,
Saccharomyces cerevisiae, Saccharomyces carlsbergensis, Saccharomyces chevalieri, Saccharomyces delbrueckii, Saccharomyces exiguous, Saccharomyces fermentati, Saccharomyces logos, Saccharomyces mellis, Saccharomyces oviformis, Saccharomyces rosei, Saccharomyces rouxii, Saccharomyces sake, Saccharomyces uvarum, Saccharomyces willianus, Saccharomyces sp., Schizosaccharomyces octosporus, Schizosaccharomyces pombe, Sporobolomyces roseus, Torulopsis candida, Torulopsis famta, Torulopsis globosa, Torulopsis inconspicua, Trichosporon behrendii, Trichosporon capitatum, Trichosporon cutaneum, Wickerhamia fluoresens, Candida arborea, Candida krusei, Candida lambica, Candida lipolytica, Candida parapsilosis, Candida pulcherrima, Candida rugousa, Candida tropicalis, Candida utilis, Crebrothecium ashbyii, Geotrichum candidum, Hansenula anomala, Hansenula arabitolgens, Hansenula jadinii, Hansenula saturnus, Hansenula schneggii, Hansenula subpelliculosa, Kloeckera apiculata, Lipomyces starkeyi, Pichia farinosa, Pichia membranaefaciens, Rhodosporidium toruloides, Rhodotorula glutinis, Rhodotorula minuta, Rhodotorula rubar, Rhodotorula aurantiaca, Saccharomycodes ludwigii, and Saccharomycodes sinenses
. For instance, the yeast cells can be of the strain
Saccharomyces cerevisiae
Hansen AS2.375, AS2.501, AS2.502, AS2.503, AS2.504, AS2.535, AS2.558, AS2.560, AS2.561, AS2.562, or IFFI1048; or
Saccharomyces carlsbergensis
Hansen AS2.420, or AS2.444.
