  • Patent number: 6482443
    Abstract: Disclosed are an antler herb medicine and a preparing method thereof. The antler herb medicine is prepared by fermenting a mixture of antler and gizzard membrane at 20-60° C. In the mixture, the weight ratio of antler to gizzard membrane is within the range of 1:10 to 10:1. The antler herb medicine contains all of the efficacious components of antler, rather than selected components. Also, the fermentation of antler brings about a great change in the composition of antler, converting high molecular weight proteins into low molecular weight proteins and polypeptides, so that the antler herb medicine is greatly improved in uptake rate in the body. Thus, the antler herb medicine can show medicinal effects of antler at a small amount.

  • Patent number: 5985592
    Abstract: In accordance with the present invention, it has been discovered that monocyte conditioned medium (MCM) obtained from patients with liver disease stimulates the proliferation of fibroblasts. Platelet derived growth factor (PDGF) has also been found to stimulate fibroproliferation of fibroblasts, and to be at least partially responsible for the fibroproliferative effect of the MCM. Further in accordance with the present invention, the effect of MCM and PDGF on the expression of c-fos and c-jun has been investigated, because c-fos and c-jun form AP-1 complexes which can stimulate genes involved in proliferation. It has recently been reported that pentoxifylline inhibits platelet derived growth factor-stimulated proliferation. The mechanism of this action of pentoxifylline is unclear. Thus, in the course of the work undertaken as part of the present invention, studies were conducted to determine whether pentoxifylline altered the expression of c-fos and c-jun.

  • Patent number: 5948442
    Abstract: This patent relates to the obtaining of two pharmaceutical forms--pulvis and ampules of the veterinary medical preparation "Enterogenin". The bioactive ingredient of the preparation is isolated by fractionation of pig small intestinal mucosa cell, extraction with acetic acid, sedimentation with ethyl alcohol, ion-exchange chromatography and diaflo ultrafiltration in the range of 0.5-2 kDa. The bioactivity of the preparation is related to two nucleopeptides: guanosine tripeptide and adenosine heptapeptide. The basic criterion for the biological action of "Enterogenin" pulvis and ampules is the activation of biosynthesis of nucleic acids and specific proteins in the muscles, liver, intestines and spleen.

    Abstract: A fluidized, injectable tissue graft composition is described. The composition comprises comminuted intestinal submucosa or protease-digested intestinal submucosa. Methods for the preparation and use of injectable tissue graft compositions are described. In preferred embodiments the tissue graft material is prepared from the intestinal submucosa comprising the tunica submucosa, the muscularis mucosa and the stratum compactum of a segment of intestinal tissue of a warm-blooded vertebrate. Effective amounts of the fluidized graft compositions can be injected to promote repair tissue defects by inducing formation of endogenous tissues.

  • Patent number: 5445957
    Abstract: This invention relates to a beta-fructofuranosidase enzyme food supplement composition, which alleviates gastrointestinal distress caused by ingested food containing oligosaccharides, comprising a beta-fructofuranosidase enzyme, a cellulase enzyme and a hemicellulase enzyme. More particularly, the enzyme food supplement composition of this invention comprises a beta-fructofuranosidase enzyme, a cellulase enzyme, a hemicellulase enzyme, a lipase enzyme and an acid protease enzyme. This invention also relates to a method of alleviating gastrointestinal distress in the gastrointestinal system of a human being, which distress is caused by ingested food containing oligosaccharides, the method comprising the step of ingesting a beta-fructofuranosidase enzyme food supplement composition comprising a beta-fructofuranosidase enzyme, a cellulase enzyme and a hemicellulase enzyme, to convert oligosaccharides contained in the ingested food to reducing sugars.
