Abstract:
PURPOSE: An eye drop composition containing beta-glucan for treating keratoconjunctivitis is provided to ensure excellent biocompatibility and to resolve the problem of high toxicity. CONSTITUTION: A pharmaceutical composition for treating keratoconjunctivitis or allergic keratoconjunctivitis contains 0.01-10 wt% of beta-1,3 glucan. The beta-1,3 glucan has a beta-1,3 main sugar chain without a beta-1,6 branch. The molecular weight of beta-1,3 glucan is 450-550 kDa. Beta-1,3 glucan is derived from Euglena Gracilis. The pharmaceutical composition additionally contains carboxymethyl cellulose and hyaluronic acid. The composition is an eye drop.
Abstract:
A method for preparing sulfasalazine hyaluronic acid compound is provided to inhibit occurrence of after-cataract by inhibiting activity of NF-kappa B(nuclear factor kappa-B) expressed when lens epithelial cell is proliferated or moved through slow degradation in capsular bags of eye. A method for preparing sulfasalazine hyaluronic acid compound comprises the steps of: PEGylating sulfasalazine by using balanced salt solution to obtain hydrophilic sulfasalazine; and adding hyaluronic acid into the hydrophilic sulfasalazine. A composition for suppressing after-cataract comprises (i) a pharmaceutical carrier such as distilled water, and (ii) the sulfasalazine hyaluronic acid compound in a sufficient amount to suppress after-cataract.
Abstract:
PURPOSE: Prox 1 siRNA which is specific to a lymphatic endothelial cell is provided to suppress protein synthesis of Prox 1 and proliferation and growth of lymphatic duct, and to effectively treat corneal edema, clouding, and graft rejection. CONSTITUTION: An inhibitor of ophthalmic lymphatic duct contains Prox 1 gene siRNA selected from the group consisting of base sequences of sequence numbers 1-12. A composite of the Prox 1 gene siRNA and cationic lipid maximally suppresses Prox 1 protein expression by improving cell delivery efficiency and stabilizing Prox 1 siRNA. The cationic lipid is mPEG-Arg-Lys-dioleyl or 3-beta-[N-(N',N'-dimethylaminoethane)carbamoyl]cholesterol(DC-Chol). The cationic lipid is formed of a cathionic liposome, a micelle, an emulsion, or a nanoparticle. [Reference numerals] (AA) Lymphangiogenesis(%); (BB) Control group; (CC) Prox 1 siRNA
Abstract:
The present invention relates to an eye drop composition for treating keratoconjunctivitis containing hydrophilic sulfasalazine and hyaluronic acid. The eye drop composition for treating keratoconjunctivitis contains the hydrophilic sulfasalazine having a density of 0.005-0.1 %(w/v), hyaluronic acid having a density of 0.01-0.5 %(w/v), and also a carrier including an aqueous solution. The carrier including the aqueous solution is selected from a group, constituted by distilled water, phosphate buffer, a balanced salt solution and a saline solution, and is pharmaceutically acceptable.
