Definitions
- the present invention relates to a therapeutic / prophylactic agent or a surgical adjuvant for ophthalmic diseases, including nuttilinase (subtilisin NAT). More specifically, the present invention relates to a therapeutic / preventive agent or surgical adjuvant for ophthalmic diseases, including Nattokinase that induces liquefaction of the vitreous body, weakening of the proliferation membrane, posterior vitreous detachment, and the like.
- the vitreous body is a transparent gel-like structure that fills the posterior force of the lens to the surface of the retina.
- a large amount of water and a small amount of low-molecular-weight substances are contained in the network structure of collagen and hyaluronic acid, which are the two major components. Etc. exist and hold.
- the retina is a membranous nerve tissue that contacts the back of the vitreous and covers the inner wall of the eyeball.
- a proliferative membrane is generated due to various causes, causing retinal detachment and vitreous hemorrhage, which causes blindness.
- vitreous surgery has been introduced as the treatment method, and surgical removal of the proliferative membrane and retinal surface peeling of the vitreous body that becomes the scaffold ("posterior vitreous detachment") are performed.
- posterior vitreous detachment Such mechanical excision always carries the risk of pulling and damaging normal retinal tissue, which is inherently vulnerable during the procedure. Therefore, an enzyme is used to induce posterior vitreous detachment, or a tissue such as a pathological proliferative membrane is chemically treated with the enzyme to reduce intraoperative complications. It was anxious to treat without doing.
- Hyaluronidase (Vitrase registered trade mark, Istafarmas-Tikicals Incorporated) has been proposed for intravitreal injection as it promotes the absorption of vitreous hemorrhage by decomposing hyaluronic acid and promoting absorption of vitreous hemorrhage. ing.
- hyaluronan-dase is the skeletal component of the vitreous It is thought that collagen fibers do not break down and do not induce posterior vitreous detachment, which is important for treatment!
- Plasmin degrades collagen fibers, the skeletal component of the vitreous body, and is thought to induce not only liquefaction of the vitreous body but also posterior vitreous detachment, and is clinically used in some ophthalmic facilities.
- plasmin needs to be extracted and purified by autologous blood force. Because of this, it is difficult to apply plasmin widely and clinically because it requires special equipment and technology. Because it takes several days to purify the serum, it cannot be applied to cases that require surgery on the same day, and there may be individual differences in the amount of plasmin activity extracted and purified. It is difficult to become law.
- an object of the present invention is to provide a novel therapeutic / preventive agent for ophthalmic diseases (particularly retinal 'vitreous diseases) using a substance that can be easily extracted and purified. More specifically, the present invention relates to an ophthalmic disease (especially retinal / vitreal disease) that uses a substance that can induce vitreous phlegm and posterior vitreous detachment and that can be easily extracted and purified. ) Provision of new therapeutic / preventive agents was a problem to be solved.
- an agent for the treatment or prevention of ophthalmic diseases, or a procedure aid, which contains Nattokinase is provided.
- the Nattokinase is derived from a Bacillus natto culture extract.
- the ophthalmic disease is a retinal vitreous disease.
- the medicament of the present invention has a vitreous liquefaction and Z or posterior vitreous detachment inducing action.
- the medicament of the present invention is administered intravitreally.
- a method for treating or preventing an ophthalmic disease or a method for assisting an operation of an ophthalmic disease comprising administering Nattokinase to a mammal including a human.
- Nattokinase for the manufacture of a prophylactic or surgical adjuvant for the treatment of ophthalmic diseases.
- Nattokinase is used as an active ingredient in the ophthalmic disease treatment / prevention agent or surgical adjuvant (also referred to herein as the agent of the present invention) according to the present invention.
- Nattokinase (subt ilisin NAT) is a single-strand protein with a capacity of 275 amino acids, so far it has a strong thrombolytic effect [Sumi et al. Experientia, 1987], and the effect of plasminogen activator It has been reported to have potentiation [Sumi et al. Hematologica, 1990] and suppressive action of plasminogen activator inhibitor [Urano et al. J Biol Chem, 2001].
- Nattokinase has a thrombolytic effect when administered orally [Sake iet al. Hematologica, 1990].
- processed foods utilizing Nattokinase-rich Natto bacteria culture extract have been used. Widely used as a health food.
- this Nattokinase is used as an alternative to plasmin that has been conventionally used. Similar to the conventional plasmin procedure, Nattokinase is administered into the vitreous cavity, and after a certain period of time, vitrectomy is started. It can be reduced. [0013] As shown in the examples in the present specification, the experimental results using rabbit eyes confirmed that the liquefaction of the vitreous body and induction of posterior vitreous detachment were confirmed, and an effect equivalent to or better than that of plasmin was expected. Has been obtained. By providing Nattokinase as a preventive agent for retinal 'treatment of ophthalmic diseases such as vitreous diseases' and a surgical aid, the disadvantages of using plasmin can be overcome.
- the Nattokinase used in the present invention may be derived from, for example, a Bacillus natto culture extract, and an expression vector containing a gene encoding Nattokinase is transformed into a host to express the gene. It can be either a recombinant Nattokinase obtained by this method, or a protein synthesized by a peptide synthesizer! /.
- a culture solution containing a high content of Nattokinase is produced by ingesting and cultivating natto bacteria in a liquid medium mainly composed of soybeans. can do.
- a method for producing a Bacillus natto culture extract is described in JP-A-2001-29977.
- a Bacillus natto-culture extract produced by the method described in JP-A-2001-299277 can be used. it can.
- any microorganism can be used as long as the microorganism used in the production of the Bacillus natto culture extract is a microorganism that is classified as Bacillus natto and is capable of producing Nattokinase.
- a commercially available natto bacterium isolated from natto may also be used.
- the type of medium used for culturing natto bacteria is not particularly limited.
- Bacillus natto can be cultured using inorganic salts such as The method for cultivating Bacillus natto is not particularly limited, and for example, it can be cultured by aeration stirring culture.
- the culture temperature is not particularly limited, but is usually about 30 to 45 ° C, particularly preferably 32 to 42 ° C.
- the culture period is not particularly limited, and can be cultured for about 3 to 4 days, for example.
- the culture supernatant after completion of the culture contains vitamin K2 in addition to Nattokinase, this culture is brought into contact with chitosan to adsorb vitamin K2 to chitosan. Can be removed.
- a concentrated solution of a natto fungus culture solution can be obtained.
- Nattokinase used in the present invention is similar to natto, natto fungus liquid or solid cultures.
- these processed products can be used as starting materials, and can be obtained by methods commonly used for separation and purification of enzyme proteins, that is, ion exchange chromatography, gel filtration chromatography, hydrophobic chromatography and the like.
- the separation and purification method the method of Sumi et al. (Japanese Patent Publication No. 61-162184, Experientia, 43, 1110 (1987), the method of Ichishima et al. (Biochimi ca et Biophysica Acta, 869, 178-184 (1986 )), Nakanishi et al.
