摘要:
The present invention relates to an anti-adhesion polymer composition capable of supporting growth factor, which effectively exhibits anti-adhesion function and, at the same time, has an excellent adhesive property so as to be able to easily and continuously adhere to a wound site, has antibacterial and hemostatic properties, and is composed of an injectable formulation suitable for use in minimally invasive surgery, laparoscopic surgery or the like. The anti-adhesion polymer composition capable of supporting growth factor comprises: 24-50 wt % of a polyethyleneglycol-polypropyleneglycol-polyethyleneglycol (PEG-PPG-PEG) block copolymer having a polyethyleneglycol (PEG) content of 65-85 wt % and a molecular weight of 6,000-20,000 Da; 0.03-5 wt % of gelatin; 0.03-5 wt % of chitosan; and distilled water.
摘要:
Disclosed herein is a method for preparing an aqueous solution of high-concentration calcium phosphate, the method comprising the steps of: preparing an acidic aqueous solution using an acidic chelating agent; and dissolving a calcium phosphate-based compound in the acidic aqueous solution, and then adding a pH-adjusting agent to the acidic aqueous solution to adjust the pH of the acidic aqueous solution. The disclosed aqueous solution does not form a precipitate after neutralization so that it can be used in various calcium-containing products, including foods, drugs, or quasi-drugs.

摘要:
The present invention relates to a carrier for growth factor related to regeneration of bone tissues that is capable of arbitrarily controlling the delivery rate of growth factors related to bone regeneration and thus especially applicable to a bone void filler in the fields of the dental or orthopedic applications.The carrier for controlling the delivery rate of the growth factor in the present invention is composed of a hyaluronic acid hydrogel having a distribution of interconnected pores and a calcium phosphate microsphere being distributed in the pores of the hyaluronic acid hydrogel. The calcium phosphate microsphere having a porosity suitable for delivery of the growth factor is positioned into the pores of the cross-linked hyaluronic acid hydrogel to complete the carrier.
