Description

本発明は、ウイルス及び真菌による感染および、ガーゼ、リネン、衣服、床材、絨毯、マット、カテーテル、器具等への汚染防止と除ウイルスと除真菌に有効な除ウイルス剤又は除真菌剤に関する。   The present invention relates to an antiviral agent or antifungal agent effective in preventing infection by viruses and fungi, and preventing contamination of gauze, linen, clothes, flooring, carpets, mats, catheters, instruments, etc., and eliminating viruses and fungi.

老人が増加している近年、寝たきりの老人人口も増加し続けており、かつ高度医療の発展に伴い免疫不全患者も増加している。老人も一種の免疫不全状態であり、これらの免疫不全者に対して、インフルエンザウイルスを含むウイルスや皮膚糸状菌を含む真菌による感染症も増加し続けており、それに伴いリネン類や衣服および、処置するためのガーゼ、カテーテル、器具などに対する汚染が拡大している。それらの感染症を防ぐために汎用されているのが次亜塩素酸、クレゾール、陽イオン界面活性剤の塩化ベンザルコニウムと塩化ベンゼトニウム、両性界面活性剤の塩化アルキルジアミノエチルグリシンおよび、ビグアナイト系薬剤のグルクロン酸クロルヘキシジンであるが、いずれも汚染後の処置にしか使用できず、汚染の防止には役立たない。一旦、リネン類が汚染されてしまえば、院内感染もしくは在宅感染が発症するばかりか、それらを取り扱う医療従事者の他に清掃員やクリーニング従事者のような第三者に対する2次感染の危険性も大きくなる。   In recent years, the number of elderly people has increased, the bedridden elderly population has continued to increase, and with the development of advanced medical care, the number of immunocompromised patients has also increased. Older people are also a kind of immunodeficient state, and infections due to viruses including influenza virus and fungi including dermatophytes continue to increase in these immunodeficient people, and accordingly linens, clothes and treatment Contamination for gauze, catheters, instruments, etc. is growing. Commonly used to prevent these infections are hypochlorous acid, cresol, cationic surfactants benzalkonium chloride and benzethonium chloride, amphoteric surfactants alkyldiaminoethylglycine chloride and biguanite drugs. Although chlorhexidine glucuronide can be used only for post-contamination treatment, it does not help prevent contamination. Once linen is contaminated, hospital infections or home infections may develop, and there is a risk of secondary infection to third parties such as cleaning workers and cleaning workers in addition to medical workers who handle them. Also grows.

一般的に、重症急性肺呼吸器症候群(SARS)や鳥インフルエンザなどのウイルスの感染予防は空気感染予防策がとられるためマスクの着用が行われている。このマスク自体に除ウイルス効果はなく、単に機械的に侵入を止めているにすぎないため二次感染の恐れがある。また、皮膚糸状菌は皮膚からはがれた剥落層内にも存在しているため、これが二次感染の現況となっている。
これらの問題は医療上または医療費上に大きな負担を強いていることは事実であるが、免疫不全人口の増大によりさらに加速することは容易に推察できる。
また、特許文献1に記載されている抗菌性消毒剤は、ガーゼ、リネン、衣服、カテーテル、器具等への半永久的維持能力は無く、洗浄によって容易に除洗されてしまう欠点がある。
特開2002−205941
In general, masks are used to prevent infection with viruses such as severe acute pulmonary respiratory syndrome (SARS) and avian influenza. This mask itself has no virus-removing effect, and merely intrusions mechanically, so there is a risk of secondary infection. Moreover, since dermatophytes are also present in the exfoliated layer peeled off from the skin, this is the current state of secondary infection.
It is true that these problems place a heavy burden on medical care or medical costs, but it can be easily inferred that they will be further accelerated by the increase in the immunodeficient population.
Further, the antibacterial disinfectant described in Patent Document 1 has a semi-permanent maintenance ability to gauze, linen, clothes, catheters, instruments, and the like, and has a drawback that it is easily removed by washing.
JP 2002-205941 A

本発明の目的は、微生物学の分類に従って、細菌とは分類を異にするウイルスや真菌までを含む微生物に広く有効な除ウイルス剤と除真菌剤製品を提供することであり、特に染色可能な除ウイルス剤と除真菌剤を提供するものである。   It is an object of the present invention to provide antibacterial and antibacterial products that are broadly effective for microorganisms including viruses and fungi that are classified differently from bacteria according to the classification of microbiology, and are particularly stainable. An antiviral and antifungal agent is provided.

上記目的を達成するべく、本発明者らは人体に安全であり、かつカテーテル、リネン類及び衣服などの繊維に染色可能な除ウイルス剤と除真菌剤の両方の性質を有す物質を検索した結果、ゲンチアナバイオレットで代表される抗菌性色素剤が最も優れていると判断した。しかし、抗菌性色素剤単独による染色では、洗浄によって容易に溶出してしまい、長時間の殺菌効果は期待できない。そこで、本発明者は抗菌性色素剤と組み合わせることで殺ウイルス、殺真菌効果増強と洗浄によって容易に脱染しない長時間の染色を可能に出来る化合物の検索を行った結果、金属剤を用いると染色が可能であり、洗浄によって容易に脱染せず、かつ従来品を上回る殺ウイルス、殺真菌効果を有する除菌剤が得られることを見いだし、本発明に到達した。   In order to achieve the above-mentioned object, the present inventors searched for a substance that has both antiviral and antifungal properties that are safe for the human body and that can be dyed on fibers such as catheters, linens, and clothes. As a result, it was judged that the antibacterial pigment represented by gentian violet was the best. However, dyeing with an antibacterial dye alone easily elutes by washing, and a long-term sterilizing effect cannot be expected. Therefore, the present inventor conducted a search for a compound that can be dyed for a long time without being easily destained by virucidal, fungicidal effect enhancement and washing by combining with an antibacterial pigment, and when using a metal agent The present inventors have found that a disinfectant that can be dyed, is not easily decontaminated by washing, and has a virucidal and fungicidal effect that exceeds that of conventional products has been achieved.

即ち、本発明は,抗菌性色素剤と金属を含有してなる除ウイルス剤又は除真菌剤及び当該除ウイルス剤又は除真菌剤で処理してなる物品である。抗菌性色素剤に金属を併用することにより、ウイルスと真菌に対しても優れた殺ウイルス及び殺真菌力を示すようになる。また、金属を使用することにより、リネン類の布、紙やカテーテルに対して脱染を少なくした染色が可能になる。   That is, the present invention is an antibacterial agent or fungicide containing an antibacterial pigment and a metal, and an article treated with the antibacterial agent or fungicide. By using a metal in combination with an antibacterial pigment, it exhibits excellent virucidal and fungicidal power against viruses and fungi. Further, by using metal, it is possible to dye linen cloth, paper, and catheter with less destaining.

本発明の除ウイルス剤又は除真菌剤は、抗菌性色素剤と金属を併用することによって、ウイルスと真菌の両方に対して相乗的殺菌効果を発揮する。特にゲンチアナバイオレットと銅、就中CuCl2の添加によってゲンチアナバイオレットの活性が増強することは、これらの併用が染色に応用できることを示している。CuCl2はゲンチアナバイオレットを染料とする染色時の色止めに使用できる。本剤で繊維の染色を行うことにより、ウイルスと真菌の汚染防止が可能となる様々な製品が考えられることになる。また、その他の抗菌性色素剤、例えばマラカイトグリーンを用いても、ゲンチアナバイオレットと同様の結果を得られる。
さらに、消毒剤、抗菌剤、ゲル化剤、固化剤、安定化剤、pH調整剤を添加して使用しても同等の効果を得ることが可能である。従って、本発明の除ウイルス剤又は除真菌剤を含有する製品は、ウイルスと真菌の汚染防止、除ウイルスと除真菌を目的として幅広く使用できる。
なお、本発明者は既に抗菌性消毒剤を特許出願しているが(特願2003−166305)、該抗菌性消毒剤は微生物学的分類の細菌に属するものを対象とし、本件の対象であるウイルス及び真菌とは学問的に異なるものである。
The antiviral agent or antifungal agent of the present invention exhibits a synergistic bactericidal effect on both viruses and fungi by using an antibacterial pigment and a metal in combination. Particularly gentian violet and copper, is to enhance the activity of gentian violet by the addition of, inter alia CuCl 2, indicating that these combination can be applied to staining. CuCl 2 can be used for coloring at the time of dyeing with gentian violet as a dye. By dyeing fibers with this agent, various products that can prevent contamination with viruses and fungi can be considered. In addition, the same results as in gentian violet can be obtained using other antibacterial pigments such as malachite green.
Furthermore, even if a disinfectant, an antibacterial agent, a gelling agent, a solidifying agent, a stabilizer, and a pH adjuster are added and used, the same effect can be obtained. Therefore, the products containing the antiviral agent or antifungal agent of the present invention can be widely used for the purpose of preventing contamination of viruses and fungi, and eliminating viruses and fungi.
The inventor has already filed a patent application for an antibacterial disinfectant (Japanese Patent Application No. 2003-166305), and the antibacterial disinfectant belongs to bacteria belonging to the microbiological classification and is the subject of this case. Viruses and fungi are academically different.

以下に本発明を詳細に説明する。
本発明において使用する抗菌性色素剤としては、ゲンチアナバイオレット、マラカイトグリーン、ブリリアントブルー、エタクリジン、アゾ色素が好ましい。アゾ色素としては例えばスルファピリジン、スルファグアニジン、ホモスルファミン、スルファチアゾールが例示できる。これ等の中でゲンチアナバイオレットとマラカイトグリーンが特に好ましい。
The present invention is described in detail below.
As the antibacterial dye used in the present invention, gentian violet, malachite green, brilliant blue, ethacridine, and azo dye are preferable. Examples of the azo dye include sulfapyridine, sulfaguanidine, homosulfamine, and sulfathiazole. Of these, gentian violet and malachite green are particularly preferred.

抗菌性色素剤は市販されているものでも、試薬として市販されているのもでも合成品でも構わない。また、液状でも固形状でも構わない。さらに、抗菌性色素剤自体でも、作成されうる塩の形態をとっていても構わない。水溶液の場合、抗菌性色素剤の濃度に制限はないが、通常0.00001〜10重量%水溶液である。除ウイルス剤と除真菌剤として使用されうる抗菌性色素剤の濃度は約0.001重量%水溶液であり、好ましく使用できる。   The antibacterial coloring agent may be a commercially available product, a commercially available reagent, or a synthetic product. Further, it may be liquid or solid. Furthermore, the antibacterial coloring agent itself may take the form of a salt that can be prepared. In the case of an aqueous solution, the concentration of the antibacterial coloring agent is not limited, but is usually 0.00001 to 10% by weight aqueous solution. The concentration of the antibacterial pigment that can be used as a virus eliminating agent and a fungicidal agent is about 0.001% by weight aqueous solution, which can be preferably used.

金属としては、マグネシウム、アルミニウム、亜鉛、鉄、コバルト、ニッケル、スズ、クロム、鉛、銅、銀、白金、それらの塩及びそれらの錯体が好ましく、銅および銀、その塩又はその錯体が特に好ましい。これらの金属は、抗菌性色素剤の除ウイルス効果と除真菌効果を増強し、かつ製品の安定化及び染色時に効力を有する。金属は、微粉末化した金属自体でも、作成されうる塩や錯体の形態をとっていても構わない。   As the metal, magnesium, aluminum, zinc, iron, cobalt, nickel, tin, chromium, lead, copper, silver, platinum, salts thereof and complexes thereof are preferable, and copper and silver, salts thereof or complexes thereof are particularly preferable. . These metals enhance the antibacterial and fungicidal effects of antibacterial pigments and have efficacy during product stabilization and dyeing. The metal may be a finely powdered metal itself or may be in the form of a salt or complex that can be prepared.

具体的に銅剤は、銅、塩化銅、硫酸銅、酢酸銅、ホウ酸銅、フッ化銅、水酸化銅、硝酸銅、リン酸化銅、セレン銅、アルセネイト銅、臭化銅、硫化銅、銅-塩基性アミノ酸であるが、好ましくは塩化銅、特に塩化第二銅と酢酸銅が好ましい。錯体としては、例えば酸性アミノ酸、クエン酸、リンゴ酸、フマール酸、オキザロ酢酸等によって形成される錯体が例示できる。銅剤は市販されているものでも、試薬として市販されているのもでも合成品でも構わない。抗菌性色素剤の染色固定に使用する銅剤は、余分な銅剤が洗浄除去されるため濃度制限はないが、人体に影響しない濃度を考慮すれば、0.001〜10重量%が好ましい。   Specifically, the copper agent is copper, copper chloride, copper sulfate, copper acetate, copper borate, copper fluoride, copper hydroxide, copper nitrate, copper phosphate, selenium copper, arsenate copper, copper bromide, copper sulfide, A copper-basic amino acid, preferably copper chloride, particularly cupric chloride and copper acetate. Examples of the complex include complexes formed with acidic amino acids, citric acid, malic acid, fumaric acid, oxaloacetic acid and the like. The copper agent may be a commercially available product, a commercially available reagent, or a synthetic product. The copper agent used for dyeing and fixing the antibacterial pigment agent is not restricted in concentration because excess copper agent is washed away, but if considering the concentration that does not affect the human body, 0.001 to 10% by weight is preferable.

具体的に銀剤は、銀、炭酸銀、臭化銀、炭酸銀、塩化銀、よう素酸銀、よう化銀、硝酸銀、亜硝酸銀、プロテイン銀、硫酸銀、亜硫酸銀、乳酸銀、トリフロオロ酢酸銀、トリフルオロメタンスルフォン酸銀、トルエンスルフォン酸銀であるが塩化銀、酢酸銀と硝酸銀が好ましく、濃度は0.001〜10重量%が好ましい。   Specifically, silver, silver carbonate, silver bromide, silver carbonate, silver chloride, silver iodate, silver iodide, silver nitrate, silver nitrite, protein silver, silver sulfate, silver sulfite, silver lactate, trifluoroacetic acid Silver, trifluoromethane sulfonate, and toluene sulfonate are preferable, but silver chloride, silver acetate, and silver nitrate are preferable, and the concentration is preferably 0.001 to 10% by weight.

本発明においては、抗菌性色素剤と金属の比は0.0001〜0.1:0.01〜5であることが好ましい。抗菌性色素剤がこの比率より小さいと、金属併用時に於ける相乗効果が期待できないし、この比率より多い抗菌性色素剤自体の皮膚刺激性による毒性の恐れがでてくる。金属の比率がこれより少ないと、抗菌性色素剤との併用による効果が期待できないし、これより多くなれば金属の析出と毒性の恐れがでてくる。   In the present invention, the ratio of the antibacterial coloring agent to the metal is preferably 0.0001 to 0.1: 0.01 to 5. If the antibacterial coloring agent is smaller than this ratio, a synergistic effect cannot be expected when the metal is used in combination, and the antibacterial coloring agent itself having a ratio higher than this ratio may cause toxicity due to skin irritation. If the ratio of the metal is less than this, the effect of the combined use with the antibacterial coloring agent cannot be expected, and if it is more than this, precipitation of the metal and a risk of toxicity appear.

本発明による除ウイルス剤と除真菌剤は、常法により任意の剤形とすることができる。例えば、粉末製剤、固化製剤、ゲル製剤、軟膏製剤、パップ製剤、水剤とすることができる。また、さらに抗感染症剤を含有させた形態、すなわち抗菌性色素剤と金属および抗感染症剤を配合した形態としてもよい。抗菌剤としては、例えば一般的に使用されているクロラムフェニコール、マクロライド、キノロン、β-ラクタム、テトラサイクリン、サルファ剤などが使用できる。   The antiviral and antifungal agents according to the present invention can be made into arbitrary dosage forms by conventional methods. For example, a powder preparation, a solid preparation, a gel preparation, an ointment preparation, a poultice preparation, and a liquid preparation can be used. Further, a form further containing an anti-infective agent, that is, a form in which an antibacterial pigment, a metal, and an anti-infective agent are blended may be used. As the antibacterial agent, for example, chloramphenicol, macrolide, quinolone, β-lactam, tetracycline, sulfa drug and the like which are generally used can be used.

本発明の除ウイルス剤と除真菌剤は、上記の様に殺菌効果増強と抗菌スペクトルが広いという特徴を有する製剤を提供できる。また、紙、綿球、ガーゼ、マスク、タオル、繊維、不織布、布地、リネン、ベットパッド、ベットカバー、寝具、オムツ、オムツカバー、靴下、靴の中敷、マット、絨毯、たたみ、床材、衣服、カテーテル、便座、タイル、用具、器具のように汚染が考えられる物品を処理することができる。また、セラミックスやカーボン繊維、カーボンチューブ、ナノカーボン、活性炭のようなカーボン製品も処理することができる。即ち、抗菌性色素剤を除ウイルスと除真菌の主成分とし、金属の添加によって抗菌性色素剤の除ウイルス効果と除真菌効果が相乗的に強くなる染色可能な本製剤を作ることが出来る。具体的な処理方法としては、例えば汚染が考えられる物品あるいは清潔を保持したい物品を本発明の除ウイルス剤と除真菌剤に浸漬したり、物品に練り込んだり、物品をコーティングしたりあるいは物品にスプレーしたりして染色することができる。また、除ウイルス剤または除菌剤を物品に封入処理をして汚染防止をすることが考えられる。   The antiviral agent and antifungal agent of the present invention can provide a preparation having the characteristics of enhanced bactericidal effect and broad antibacterial spectrum as described above.

As a specific treatment method, for example, an article that is considered to be contaminated or an article that needs to be kept clean is immersed in the antibacterial and antifungal agent of the present invention, kneaded into the article, coated with the article, or coated on the article. It can be dyed by spraying. It is also conceivable to prevent contamination by enclosing an article with a virus eliminating agent or a disinfecting agent.

以下、実施例で本発明を説明する。
実施例1
ゲンチアナバイオレットとCuCl2併用における抗HA効果
MDCK細胞を用いて培養したインフルエンザウイルス(influenzae A/WSN3, H1N1)を用いて、赤血球凝集素(HA)の力価(HA価)を定法により、目視にて完全凝集を判定した。つまり、1.1x107 influenzae A/WSN3の2倍希釈系列を作成後、0.5%ニワトリ赤血球浮遊液を等量添加し、4℃で一時間静置後、凝集の起こる最低濃度であるHA価を求めた。このHA価は320であった。このインフルエンザウイルス(influenzae A/WSN3,以下ストックウイルス液と略す)100μLと各検体100μLを37℃60分反応させ、その後、各反応系50μLに0.5%ニワトリ赤血球を50μL加え、4℃60分後にHA価を判定した。コントロールとしてリン酸緩衝生理食塩水を用いた。
結果は、リン酸緩衝生理食塩水、0.001%ゲンチアナバイオレット(GV)、0.001%GV+0.0001%CuCl2と0.0001%CuCl2の順に、320、160、40、160であり、GVとCuCl2の併用により、HA価で8倍の不活化作用が確認された。
Hereinafter, the present invention will be described by way of examples.
Example 1
Anti-HA effect in combination with gentian violet and CuCl 2
Using an influenza virus (influenzae A / WSN3, H1N1) cultured using MDCK cells, complete agglutination (HA) titer (HA titer) was determined visually by a standard method. In other words, after preparing a 2-fold dilution series of 1.1x10 7 influenzae A / WSN3, add an equal volume of 0.5% chicken erythrocyte suspension, and let stand at 4 ° C for 1 hour, then obtain the HA titer, the lowest concentration at which aggregation occurs. It was. The HA value was 320. 100 μL of this influenza virus (influenzae A / WSN3, hereinafter abbreviated as stock virus solution) and 100 μL of each sample were reacted at 37 ° C. for 60 minutes, and then 50 μL of 0.5% chicken erythrocytes were added to 50 μL of each reaction system. Judgment was made. Phosphate buffered saline was used as a control.
Results, phosphate-buffered saline, 0.001% gentian violet (GV), in the order of 0.001% GV + 0.0001% CuCl 2 and 0.0001% CuCl 2, a 320,160,40,160, the combination of GV and CuCl 2 As a result, an inactivation effect of 8 times in HA value was confirmed.

実施例2
ゲンチアナバイオレットとCuCl2併用時の感染価(tissue culture infectious dose、50%感染価、TCID50=10-n)に及ぼす影響
ストックウイルス液を希釈した16HA価のインフルエンザウイルス(influenzae A/WSN3)に0.0063%ゲンチアナバイオレット(GV)、0.0031%GV、0.0031%GV+0.0016%CuCl2と0.0063%CuCl2、0.25%I2を等量混合し、3時間後にサンプリングした溶液をMDCK細胞に感染させた。72時間培養後に細胞変性を観察し、Read and Munch法に従ってTCID50を算出した。
結果は、25mMリン酸緩衝液(pH7.2)、0.0063%ゲンチアナバイオレット(GV)、0.0031%GV、0.0031%GV+0.0016%CuCl2、0.0063%CuCl2、0.25%I2の順に、5.60、1.50、2.24、1.75、4.26、1.75(TCID50=10-n)であった。GV単剤、もしくはCuCl2単剤に比べ、GVとCuCl2の併用は優れた効果を示していた。また、その併用効果は80倍以上の低濃度であるにもかかわらず、0.25%I2と同程度の効果であった。
Example 2
Effect on infectious titer (tissue culture infectious dose, 50% infectious titer, TCID 50 = 10 -n ) when combined with gentian violet and CuCl 2 % Gentian violet (GV), 0.0031% GV, 0.0031% GV + 0.0016% CuCl 2 , 0.0063% CuCl 2 and 0.25% I 2 were mixed in equal amounts, and the sampled solution was infected with MDCK cells after 3 hours. Cell degeneration was observed after culturing for 72 hours, and TCID 50 was calculated according to the Read and Munch method.
The results are as follows: 25 mM phosphate buffer (pH 7.2), 0.0063% gentian violet (GV), 0.0031% GV, 0.0031% GV + 0.0016% CuCl 2 , 0.0063% CuCl 2, 0.25% I 2 , 5.60, 1.50 2.24, 1.75, 4.26, 1.75 (TCID 50 = 10 −n ). Compared with GV alone or CuCl 2 alone, the combined use of GV and CuCl 2 showed excellent effects. The combined effect was as high as 0.25% I 2 even though the concentration was 80 times lower.

実施例3
染色布のインフルエンザウイルスに対する不活化効果
あらかじめ3%タンニン酸で処理した綿布を0.001%GV液で加温染色し、洗浄後、0.01%CuCl2液で後媒染し、ソーピングして洗浄した染色布および同行程の非染色布、銅単独媒染布について検討した。染色あるいは媒染の温度はひろく染色で用いられている室温から100℃以上の高圧高温も可能である。染色布に50μLのストックウイルス液を希釈した16HA価のインフルエンザウイルス(influenzae A/WSN3)を滴下し、1時間後と3時間後に残存しているウイルス感染価を実施例2と同様にTCID50で算出した。
1時間後の結果は、非染色布、GV染色、GV+CuCl2染色、CuCl2染色の順のTCID50は、4.75、2.38、1.38、3.5(TCID50=10-n)、3時間後では、4.75、2.21、<1、3.5であった。染色布においても、GV単剤、もしくはCuCl2単剤に比べ、GVとCuCl2の併用は10倍から100倍程度、非染色布に比しては3,000〜50,000倍程度優れたインフルエンザウイルス不活化効果を示した。
上記、HA価、感染価及び染色布の結果から、GV+ CuCl2に代表される抗菌性色素剤と金属の併用は、繊維の汚染防止ばかりか汚染後の除ウイルスもしくは殺ウイルスとして有効と考えられる。
Example 3
Inactivation effect of dyed cloth against influenza virus A cotton cloth previously treated with 3% tannic acid was warm-dyed with 0.001% GV solution, washed, and then post-mordanted with 0.01% CuCl 2 solution, soaped and washed A non-dyed cloth and a copper mordanting cloth in the same process were examined. The dyeing or mordanting temperature can be from room temperature to 100 ° C or higher, which is widely used for dyeing. 16 HA titer influenza virus (influenzae A / WSN3) diluted with 50 μL of stock virus solution was dropped onto the dyed cloth, and the virus infection titer remaining after 1 hour and 3 hours was measured with TCID 50 as in Example 2. Calculated.
The results after 1 hour indicate that the TCID 50 in the order of non-dyed cloth, GV dyeing, GV + CuCl 2 dyeing, CuCl 2 dyeing is 4.75, 2.38, 1.38, 3.5 (TCID 50 = 10 −n ), and after 3 hours 4.75, 2.21, <1, 3.5. In the case of dyed cloth, GV and CuCl 2 combined use is 10 to 100 times better than GV alone or CuCl 2 alone, and 3,000 to 50,000 times better inactivation of influenza virus than non-dyed cloth. Showed the effect.
From the above results of HA value, infectivity value and dyed cloth, the combined use of antibacterial pigments such as GV + CuCl 2 and metal is considered to be effective not only for preventing fiber contamination but also for virus removal or virus killing after contamination. .

試験菌は、皮膚糸状菌であるTrichophyton mentagrophytes Fu-19とMicrosporum canis
Fu-22を用いた。抗菌力測定用の培地としてサブローグルコース寒天培地を使用した。試験菌は、サブロー寒天培地にて生育してきたコロニーをサブロー液体培地に懸濁し、107CFU/mLに調整した。2倍希釈系列の被検液含有のサブローグルコース寒天培地に調整された試験菌の5μLを接種し、各薬剤の各真菌に対する抗菌力を最小発育阻止濃度(MIC)で求めた。
結果は、Trichophyton mentagrophytes Fu-19とMicrosporum canis Fu-22ともにGVとCuCl2のMIC値は、0.00005%と0.05%であった。CuCl2の濃度を1/4MICである0.0063%に固定した条件下でGVのMICを求めた結果、GVのMIC値はTrichophyton mentagrophytes Fu-19とMicrosporum canis Fu-22の順に、0.000025%と0.0000125%となった。GV単剤に比べCuCl2の併用によって、その効果は2倍から4倍増強された。
Example 4
Antifungal effect against filamentous fungi Test bacteria are Trichophyton mentagrophytes Fu-19 and Microsporum canis
Fu-22 was used. Sabouraud glucose agar was used as a medium for measuring antibacterial activity. The test bacteria were prepared by suspending colonies that had grown on the Sabouraud agar medium in a Sabouraud liquid medium and adjusting to 10 7 CFU / mL. 5 μL of the prepared test bacteria were inoculated on a Sabouraud glucose agar medium containing the test solution in a 2-fold dilution series, and the antibacterial activity of each drug against each fungus was determined at the minimum inhibitory concentration (MIC).
As a result, the MIC values of GV and CuCl 2 were 0.00005% and 0.05% for both Trichophyton mentagrophytes Fu-19 and Microsporum canis Fu-22. As a result of obtaining the GV MIC under the condition that the CuCl 2 concentration is fixed to 0.0063% which is 1/4 MIC, the GV MIC values are 0.000025% and 0.0000125% in the order of Trichophyton mentagrophytes Fu-19 and Microsporum canis Fu-22, respectively. It became. Compared to GV alone, the combined use of CuCl 2 enhanced the effect by 2 to 4 times.

実施例5
染色布の糸状菌に対する抗真菌効果
実施例3で作成した染色布(1x0.5cm)に5x103CFUのTrichophyton mentagrophytes Fu-19菌液を接種し、それをサブロー寒天培地上に置いて10日間培養した。培養後、染色布をサブロー液体培地中で強力にボルテックスし、上清を希釈後サブロー寒天培地に塗抹・培養後、残存生菌数を計測した。
結果は、非染色布、GV染色布、GV+ CuCl2染色布の順に、1.2x106、3.5x102、5.0x101であった。何れにしても、GV単剤よりはGV+ CuCl2併用のほうが、7倍の、非染色布に対しては20,000倍殺真菌効果が確認できた。
Example 5
Antifungal effect of dyed fabric against filamentous fungus Inoculated with 5 × 10 3 CFU of Trichophyton mentagrophytes Fu-19 fungus on the dyed fabric (1 × 0.5 cm) prepared in Example 3 and placed on Sabouraud agar for 10 days did. After culturing, the dyed cloth was vortexed strongly in Sabouraud liquid medium, the supernatant was diluted, smeared and cultured on Sabouraud agar medium, and the number of remaining viable bacteria was counted.
The results were 1.2 × 10 6 , 3.5 × 10 2 , and 5.0 × 10 1 in the order of non-dyed fabric, GV dyed fabric, and GV + CuCl 2 dyed fabric. In any case, GV + CuCl 2 combined with GV + CuCl 2 was 7 times more effective than GV single agent, and 20,000 times fungicidal effect against undyed cloth.
