  • Patent number: 8642630
    Abstract: It relates to an endogenous repair factor production accelerator which comprises one or at least two selected from prostaglandin (PG) I2 agonist, EP2 agonist and EP4 agonist. Since prostaglandin (PG) I2 agonist, EP2 agonist or EP4 agonist has various endogenous repair factor production accelerating action, angiogenesis acceleration action and stem cell differentiation induction action, it is useful as preventive and/or therapeutic agents for ischemic organ diseases (e.g., arteriosclerosis obliterans, Buerger disease, Raynaud disease, myocardial infarction, angina pectoris, diabetic neuropathy, spinal canal stenosis, cerebrovascular accidents, cerebral infarction, pulmonary hypertension, bone fracture, Alzheimer disease, etc.) and various cell and organ diseases.

  • Patent number: 8617614
    Abstract: The present invention provides a microsphere with a slow-release period from about two weeks to about four weeks following administration, to enable a higher content of a drug to be included, to suppress an initial burst of the drug, and to maintain an optimal, effective blood concentration during the slow-release period. In a microsphere containing a drug and polylactic acid/glycolic acid (PLGA) copolymer, the amount of PLGA copolymer per part by weight of the drug is from about 3 to about 10 parts by weight; the average particle size of the microsphere is from about 20 to about 50 ?m; and (3) the PLGA copolymer has a weight-average molecular weight from about 10,000 to about 50,000 and a PLGA compositional ratio from about 75/25 to about 50/50. The microsphere promotes the production of various endogenous repair factors useful against various tissue disorders.
