Abstract:
PURPOSE: A pharmaceutical composition containing EGCG(epigallocatechin gallate) is provided to suppress differentiation of cytotoxic Th17 cells and to prevent or treat Sjogren syndrome, Behcet syndrome, or lupus. CONSTITUTION: A composition for preventing or treating Sjogren syndrome, Behcet syndrome, or lupus contains EGCG(epigallocatechin gallate) compound or salt thereof as an active ingredient. The EGCG suppresses or reduces differentiation of undifferentiated T cells into Th17 cells. A method for activating regulatory T cells comprises a step of treating the EGCG compounds or salt thereof to the T cells(Treg) in vitro. A functional food for treating or preventing Sjogren syndrome, Behcet syndrome, or lupus contains the EGCG compound or salt thereof as an active ingredient. A composition for suppressing immunity contains the EGCG compounds or salt thereof as an active ingredient.
Abstract:
PURPOSE: A composition containing Grim19 for preventing or treating immune diseases is provided to suppress cytotoxic Th17 cell differentiation and to activate regulatory T cells. CONSTITUTION: A composition for preventing or treating immune diseases contains Grim19 protein as an active ingredient. The Grim19 protein has an amino acid sequence of sequence number 1. The immune diseases are autoimmune diseases, inflammatory diseases, and transplantation rejection diseases of cells, tissues, or organs. A method for activating regulatory T cells comprises a step of treating Grim 19 protein or an expression vector to the T cells. The expression vector contains a polynucleotide encoding Grim19 protein.
Abstract:
PURPOSE: A pharmaceutical composition containing Vitis vinifera seed extract is provided to prevent and treat gastrointestinal ulcer. CONSTITUTION: A pharmaceutical composition for preventing or treating gastrointestinal ulcer contains Vitis vinifera seed extract and pharmaceutically acceptable carrier. The extract of Vitis vinifera seeds contains 80-130 of procyanidolic value(PCV); 30% or less of (+)catechin and (-) epicatechin; and 95-105% of proanthocyanidin. A method for preparing the Vitis vinifera seed extract comprises: a step of extracting Vitis vinifera seed seeds in a mixture solvent of acetone and water and filtering; a step of distilling liquid and removing acetone; a step of saturating sodium chloride and filtering; a step of extracting the liquid with ethyl acetate and concentrating; and a step of adding chloroform and filtering to obtain precipitate.

PURPOSE: A pharmaceutical composition containing Vitis vinifera for preventing or treating osteoarthritis is provided. CONSTITUTION: A pharmaceutical composition for preventing or treating osteoarthritis contains Vitis vinifera extract and pharmaceutically acceptable carrier. Osteoarthritis is caused by aging, obesity or trauma. The Vitis vinifera extract contains 80-130 of procyanidolic value(PCV), 30% or less (+) catechin and (-) epicatechin, and 95-105% of proanthocyanidine. A method for producing Vitis vinifera extract comprises: a step of extracting Vitis vinifera and mixture of acetone and water at room temperature and filtering; a step of distilling remaining liquid and removing acetone; a step of saturating sodium chloride and filtering; a step of extracting with ethyl acetate and concentrating; and a step of adding chloroform and precipitating.
Abstract:
A method for preparing extracts from seeds of Vitis Vinifera is provided to reduce the quantity of acetone consumed for extraction by using a mixed solvent of water and acetone while securing a high yield. A method for preparing extracts from seeds of Vitis Vinifera comprises the following steps of: extracting an extract from a mixture of pulverized seeds of the Vitis Vinifera and a acetone/water mixed solvent in a mixing ratio of 1 to 1-2 at a room temperature and filtering the extract; removing the acetone by distilling the obtained extract and saturating the extract with sodium chloride; extracting the saturated extract by ethylacetate and concentrating the extract; and adding chloroform to the concentrated extract to obtain precipitate.
