Definitions
- the present invention relates to a papillary tube insertion material.
- a torsion bar having a diameter of about 3 mm and a length of about 7 cm, the tip of which is cut diagonally, and the rear end of which is a band of about 5 mm in width
- a so-called thread-shaped twisted thread bar with a twisted thread bundled and further impregnated with an antibiotic, and then solidified with a binder (TatePragoo B: manufactured by Denka Pharmaceutical Co., Ltd., Tateboint: manufactured by Nihon Eiken Co., Ltd.)
- the lactating duct has the ability to heal papillary stenosis, the U wound, and has the ability to prevent mastitis. It has the drawback that there is nothing.
- the present invention is a simple process of inserting a rod-shaped insertion material into a papillary duct, and aims at treating papillary duct damage and treating a papillary duct stenosis after surgical treatment.
- the gist of the present invention is a human papillary tube obtained by molding chitin or a chitin derivative, or a human papillary tube obtained by coating or impregnating a support with chitin or a chitin derivative.
- the chitin used in the present invention includes N-acetyl-D-glucosamine, which is contained in shrimp, shrimp and the like, insects such as grasshoppers and beetles, and squid shells, etc.
- chitin derivatives include various deacetylated chitins obtained by partially deacetylating the above-mentioned chitin, chitosan (particularly chitin having a degree of deacetylation of 80% or more), carboxymethylated chitin, hydroxy 10 sheylated chitin, Chemically modified chitin derivatives such as sulfonated chitin
- Examples of the support include silk, collagen, cellulose, nylon, polyethylene, polypropylene, polyester, Teflon, and other yarns, sponges, and cloths made of materials that are harmless to living organisms and are flexible. be able to.
- the human papillary tube formed by molding the chitin or chitin derivative (hereinafter referred to as chitin or the like) of the present invention, or a papillary tube insertion material obtained by coating or impregnating a support with chitin or the like may be used, if necessary.
- Hardness by coating starch, polyvinyl alcohol, carboxymethylcellulose sodium salt, alkyne 25 formic acid, or a salt thereof as a binder. can be provided.
- a thread, sponge, cloth, or the like prepared from chitin or the like is molded into a rope or rod having a diameter of l to 5 mm, preferably 2 to 3 mm.
- a binder solution of 1 to 50 w / v%, preferably 1 to 10 O wZv% is applied and dried to prepare a rod having a diameter of about 3 mm, which is 1 to 10 cm in length, preferably 1 to 10 cm. More preferably, it can be manufactured by shaping into a rod shape of 3 to 7 cm and cutting the tip at a right angle (direct cut) or obliquely (oblique cut).
- a support such as a rod, a thread, a sponge, or a cloth
- a 1-50 w / V% solution or dispersion wave of chitin and / or a chitin derivative, preferably 1-10 wZv% is applied or impregnated.
- wZv% From 1 to 50 wZv%, preferably from 10 to 30 wZv%, and dried to produce a rod with a diameter of 1 to 5 mm, preferably 2 to 3 mm, or After the support is coated with chitin or the like, it is molded into a rope or rod, a binder solution is applied and dried to produce a rod, and the rod is made to have a length of 1 to: L 0 cm, preferably 3 to 7 cm.
- a method of manufacturing by cutting directly or obliquely can be cited.
- the chitin or the like used in the present invention may be chitin or the like singly or a mixture of two or more kinds.
- the above-mentioned silk, collagen, cellulose, nylon, polyethylene, polypropylene Using a mixture of yarn, sponge, cloth, etc., made of chitin or the like, and a yarn, sponge, cloth, etc., made of a flexible material that is harmless to the living body such as polyester, Teflon, etc. It may be processed to the same size.
- the use of the papillary tube filler of the present invention to cure papillary stenosis or papillary tract injuries after surgical treatment of papillary stenosis and to prevent mastitis is currently described.
- the insertion of the papillary material of the present invention into the papillary tube allows the migration of various cells involved in wound healing, does not induce a tissue reaction, and achieves extremely excellent angiogenesis. It has a granulocyte tissue augmentation effect and has antibacterial properties, so it has a direct promoting effect on healing of papillary stenosis after surgical treatment, and also promotes epithelial regeneration and prevents the invasion of various bacteria. it is conceivable that.
- the undiluted solution is extruded from a 0.1 mm x 500 hole nozzle into a 1.5 m long primary coagulation bath containing 10 liters of ethylene glycol, 1.5 kg of ice and 1.8 kg of potassium hydroxide.
- the bobbin on which the yarn was wound was washed with running water for 12 hours, immersed in hot water at 70 to 80 ° C for 4 hours, immersed in ethanol for 24 hours, wound around a skein machine, and air-dried.
- the yarn was moistened with water, and the 18 yarns were twisted into a yarn having a diameter of 5 mm.
- Polyvinyl alcohol (Wako Pure Chemical Co., Ltd.) Toyo Co., Ltd. was immersed in a 7 wZv% aqueous solution having a degree of polymerization of about 1500) to produce a twisted thread coated with polyvinyl alcohol on 0 cm of lmll, and then dried under reduced pressure.
- a papillary tube insertion material (A) of the present invention was prepared using a silicone tube having a diameter of 5 mm and a width of 5 mm.
- Example 1 instead of polyvinyl alcohol, a sodium salt of carboxymethylcellulose (manufactured by Nacalai Tesque, Inc., a first-class reagent) was immersed in a 2 V% aqueous solution to give 0.5 m1Z10 cm of carboxymethylcellulose. Except for the application of sodium salt, a papillary tube with a diameter of 3 mm and a length of 6.5 cm was inserted in the same manner as in Example 1
- Sodium salt of carboxymethylcellulose (Nacalai Tesque Co., Ltd., first-class reagent) A 2 w / v% 7k solution was applied at 2.0 cm 1Z10 cm and then dried under reduced pressure. Obtain the 3 mm diameter rod to a length of 6.5 cm and bevel the end (about 45 degrees in the length direction) or cut directly. Then, a papillary tube insertion material (C) of the present invention was produced by filling a 5 mm-wide silicone tube.
- the papillary tube-inserted material of the present invention prepared as described above is applied to the nipple tube of a dairy cow with nipple tube stenosis, or a dairy cow (both of Holstein type) after a dilation operation of the ostium of the nipple tube stenosis. Inserted. Milking was performed twice a day, and after milking, a new teat tube insertion material of the present invention was inserted each time milking was performed, and changes in the nipple were observed daily. The outcome and mastitis status are shown in Table 1.
- nipple tube insert (A) With the use of nipple tube insert (A), swelling and pain of the nipple was mild, but there was no effect on the treatment procedure or milking.
- the shape of the tip was slightly more difficult to insert than a straight one, but there was little irritation to the papillary duct, and there was no particular inconvenience for mild stenosis.
- papillary tube therapy (Table 1, No. 7) and papillary tube stenosis (Table 1, No. 7) and papillary tube stenosis that were not infected with mastitis were compared with the conventional commercially available papillary tube treatment (Teichiyuichi Point). It was used for the papillary duct (No. 8) of the ostium after opening operation. The experiment was stopped because mastitis occurred after 7 days of use and papillary stenosis did not improve. .
