Patent number: 6197290Abstract: Disclosed are cholesterol-depressant, coated or non-coated tablets for oral administration, which comprise an anion exchange resin of formula (I): wherein X represents a physiologically-acceptable counter ion; and p represents an average degree of polymerization, and is larger than 10,000, silicon dioxide and crystalline cellulose, but not containing water. The non-coated tablets are preferably coated with cellulosic substances. The tablets are easy to take, as being not bitter. The dose of the tablets can be decreased, since the tablets can contain a large amount of the active ingredient. The mixture comprising the constituent components can be directly tabletted in the absence of water.Type: GrantFiled: January 13, 1999Date of Patent: March 6, 2001Assignee: Hisamitsu Pharmaceutical Co., Inc.Inventors: Takeshi Goto, Tatsuya Meno

Patent number: 6197293Abstract: Replication-competent adenovirus vectors specific for cells which allows a probasin transcriptional response element (PB-TRE) to function, such as cells which express the androgen receptor (AR), and methods of use of such viruses are provided. These viruses comprise an adenoviral gene under control of a transcriptional regulatory portion of a PB-TRE, which is in turn dependent upon AR expression. The gene can be, for example, a gene required for viral replication or the adenovirus death protein gene (ADP). The viruses can also comprise at least one additional adenoviral gene under control of at least one additional prostate-specific transcriptional response element, such as that controlling prostate-specific antigen expression (PSA-TRE). Thus, virus replication can be restricted to target cells exhibiting prostate-specific gene expression, particularly prostate carcinoma cells.Type: GrantFiled: March 2, 1998Date of Patent: March 6, 2001Assignee: Calydon, Inc.Inventors: Daniel R. Henderson, Eric R. Schuur, De-Chao Yu

Patent number: 6197295Abstract: The present invention solves the need for non-toxic forms of selenium which is an essential part of the human diet. This invention provides novel dried-yeast products containing selenium as well as a method of producing the dried yeast products. The method uses selenium having high biological activity but low toxicity. The invention also provides nutritional supplements containing the novel selenium containing dried yeast products and methods of administering these products and supplements to improve human health. The invention also provides a practically non-toxic yeast selenium product having increased intracellular selenium concentrations and methods to reduce tumor cell growth by administration of a selenium yeast product comprising yeast Saccharomyces boulardii sequela PY 31 (ATCC 74366) in combination with chemotherapeutic agents.Type: GrantFiled: May 3, 1999Date of Patent: March 6, 2001Assignee: Viva America Marketing CorporationInventors: Houn Simon Hsia, Ping Yang, Michael Arnold

Patent number: 6197296Abstract: A method of forming a tissue equivalent is described. A length of polyester tube is threaded over a mandrel (H) and attached at either end by clips at A and D. A block (F) is then screwed into place. The polyester is then pre-soaked by injecting through Tap (2) an acidified collagen solution for approximately one hour. After a suitable period of time the excess solution is aspirated off. Following this stage, a second, alkaline solution is injected into the apparatus which contains smooth muscle cells (SMC). Thus, neutralisation of the collagen impregnated within the fabric of the tube occurs leading to spontaneous fibrillogenesis within the interstices of the cloth, eliminating the risk of delamination. The apparatus is then incubated. The collagen contracts down onto the fabric tube and the cell-impregnated gel becomes incorporated into the presoaked collagen. The pre-impregnated collagen and the collagen provided in the aqueous mixture contract down as one into a coherent whole with the SMC.Type: GrantFiled: July 21, 1997Date of Patent: March 6, 2001Assignee: National Heart Research FundInventors: Alban Davies, Sarah Haynes, Tom Browne, John Kearney

Patent number: 6197297Abstract: A monoclonal antibody which is specific to a polypeptide having a molecular weight of 18, 500±3,000 daltons on SDS-PAGE and a pI of 4.9±1.0 on chromatofocusing. The monoclonal antibody is obtainable from hybridomas and can be used for the purification and detection of the polypeptide. The polypeptide strongly induces the IFN-&ggr; production by immunocompetent cells with only a small amount, and does not cause serious side effects even when administered to human in a relatively-high dose.Type: GrantFiled: November 15, 1995Date of Patent: March 6, 2001Assignee: Kabushiki Kaisha Hayashibara Seibutsu Kagaku KenkyujoInventors: Toshio Kunikata, Mutsuko Taniguchi, Keizo Kohno, Masashi Kurimoto
