- Patent Literature Magnetite-containing crystallized glass as a ferromagnetic material and magnetite crystal by high frequency induction thermal plasma method (both non-patent literatures)
- Non-Patent Document 5 Disclosure of the invention
- an object of the present invention is to provide a therapeutic agent for cancer that is easy to transport by force and easily stops at an affected part.
- a method for producing a cancer therapeutic agent according to the present invention comprises an acidic or neutral first solution prepared by dissolving gold and insoluble sulfonic acid amide in an alkaline solution. Into the aqueous solution of
- Enzyme that catalyzes the hydrolysis m of the rubonic acid amide may react with components in the first aqueous solution or gel with the addition of external X energy Add a second aqueous solution of the organic polymer,
- the obtained precipitate is dried.
- the organic polymer is to be gelled by the reaction with the components in the first aqueous solution
- the second aqueous solution is added to the first aqueous solution
- the first aqueous solution takes in the first aqueous solution and gels.
- the form of the second aqueous solution to be added is a droplet
- the second aqueous solution gels into particles.
- the carboxylic acid amide is hydrolyzed by the action of the enzyme held in the gel, and the generated hydride ions increase the pH of the first aqueous solution.
- the metal dissolved and ionized in the first aqueous solution is combined with the hydroxide ion to form a precipitate.
- the above enzyme is a gel
- the hydrolysis proceeds only inside the gel (particle) and in the vicinity of the gel (particle), and a precipitate reflecting the shape of the gel (particle) is generated. Since the gel (particles) is porous, the sediment becomes porous and the specific gravity is small.
- the metal can be manufactured to Lee Tsu Application Benefits A particles exhibiting radioactive to be Lee Tsu Application Benefits um, if there iron Magunetai preparative exhibiting magnetism (F e 3 ⁇ 4) or My bets to mug ( ⁇ over F e 2 0 3) particles can produce a 'certain.
- it may contain zinc, magnesium, manganese, etc. in addition to iron.
- carboxylic acids Ami de is broadly understood containing urea may be one represented by the general formula RCONH 2. That is, R is not particularly specified, and may be an amino group in addition to a residue obtained by removing a carbonyl group from a carboxylic acid. When R is an amino group, it is urea.
- the organic polymer When the organic polymer is alginate, by reaction with iron ions, it is preferable to use a salt of an alkylcellulose derivative because it gels by the reaction with yttrium ions.
- the organic polymer When the organic polymer is albumin, it gels by gentle heating, and when it is agar or gelatin, it gels by cooling.
- the organic polymer When the organic polymer gels in response to external energy application, it is preferable that the organic polymer be gelled in advance and then added to the first aqueous solution.
- the organic polymer when the organic polymer is pectic acid, it gels by the reaction with sugar, and when it is carrageenan, it gels by the reaction with the force of room temperature while cooling. In these cases, sugar or potassium ion may be added to the first aqueous solution in advance. The sugar can be removed by baking after the formation of the precipitate.
- a vibrating orifice method may be used in addition to dropping or spraying with a suvoy.
- the aqueous solution is ejected from an orifice with a hole diameter of about several tens of 11 m that is ultrasonically vibrated.
- the particle size of the droplet is determined by the following equation, and by controlling the vibration frequency and the concentration of the aqueous solution, it is possible to produce fine droplets having a uniform particle size.
- d ⁇ (6 QC) / (% f) ⁇ 1/3
- FIG. 1 is an SEM photograph showing the gel particles of Example 1 (after firing).
- FIG. 2 is an SEM photograph showing the gel particles of Example 2 (after drying).
- FIG. 3 is an SEM photograph showing the gel particles of Example 2 (after firing).
- a first aqueous solution containing 75 g of urea and a second aqueous solution containing 1 mg of perase (derived from rapeseed) and 330 mg of carboxymethylcellulose sodium salt were prepared.
- the second aqueous solution (10 mL) was dropped by a dropper. Immediately after dropping, the droplets individually gelled. The gel particles were allowed to stand at 36 ° C for 4 days, washed with water and ethanol in that order, and lyophilized. Next, the dried gel particles were heated at a rate of 5 ° C./min, and calcined by maintaining them at various temperatures of 6′00 to 130 ⁇ X for 2 hours. The diameter of the dried gel particles was about 2 to 3 mm, and was 0.5 to 1 mm after firing.
- Figure 1 shows a scanning electron microscope (SEM) photograph of the gel particles fired at 110 ° C.
- the upper part shows the appearance and the lower part shows the cross section.
- the right picture is an enlarged view of a part of the left picture.
- the inside of the gel particles had a honeycomb shape, even though there were no holes on the surface of the gel particles. This point is from 600 to 1 200
- the dried gel particles were heated at a rate of 5 ° C./min, and calcined by holding at 400 ° C. for 3 hours in a mixed gas atmosphere of 70 C 02 +30.
- the diameter of the particles was about 1.5 mm, and was about 0'5 mm after firing.
- Figure 2 shows an SEM photograph of the dried gel particles.
- the upper row shows the appearance of a certain gel particle
- the lower row shows the appearance of another gel particle that has broken into two when dried
- the right picture is an enlarged view of a part of the left picture in each row.
- Figure 3 shows an SEM photograph of the gel particles after firing. As can be seen, the surface of the gel particles has no holes Nevertheless, the inside was hollow.
- Carrier gas for powder supply Ar 5 L / min
- Plasma gas composition Ar 90 L / niin + O 25 L / min
- High frequency oscillator Plate input 40 kW, frequency 4 MHz
- the obtained microspheres were dropped into water in a beaker, they reached the bottom at a depth of 10 cm from the water surface in 1 second.
