Abstract
Description
例示的な実施形態
本発明の実施形態の最初の概要が以下に提供され、次に特定の実施形態がさらに詳細に説明される。この最初の概要は、読者が技術的概念をより迅速に理解するのを助けることを目的としているが、その主要または本質的な特徴を特定することを意図しておらず、請求された請求の範囲を制限することも意図していない。
実施例
爪真菌症(OMC)は、白または黄色の爪の変色、爪の肥厚、および爪床からの爪の分離を引き起こす皮膚糸状菌によって引き起こされる、つま先の爪の一般的な真菌感染症である。OMCは一般的な爪の病気であり、米国では3,500万人以上が罹患している。それはすべての爪の病気の約半分を占める。爪真菌症の世界的な有病率は、すべての成人の10%である。この割合は、60歳以上の成人では20%に増加する。全身性抗真菌薬が最も効果的な治療法であり、メタアナリシスでは、テルビナフィンで約70%、イトラコナゾールで60%、フルコナゾールで50%の真菌性治癒率が示されている。経口投与は、吐き気、めまい、嘔吐、肝障害などの全身性副作用を引き起こす。多くの患者は、肝臓に損傷を与える可能性があるため、被験者にならない。テルビナフィン治療に対するトリコフィトン耐性は新たな問題である。この病気を治療するためのより良い局所薬が切望されている。
約105cfu/mlのC.acnesが60mMのNORGに晒された。3分後に細菌は検出されなかった。n=3(**=p<0.01、***=p<0.001)。(図11を参照)。
60 mMの一酸化窒素放出溶液(NORS)と60 mMの一酸化窒素放出ゲル(NORG)を調製して、それぞれからの一酸化窒素放出を比較した。pH3.5の各組成物の約1mlを、化学発光検出器に接続されたブローオーバー装置に導入して、NO生成を測定した。キャリアガスとして窒素を1L / minの流量で使用した。(図12および表1を参照)。
さらに、図13は、pH3.5で60mMのNORSおよび60mMのNORGに曝露した後の黄色ブドウ球菌の濃度を示している。より具体的には、約105cfu/mLの細菌をサンプルに入れ、5秒間ボルテックスした。曝露時間が終了した後、反応をNaOHで中和した。次に、サンプルを5秒間ボルテックスし、希釈し、プレーティングしました。溶液とゲルの間の各時点で有意性は見られなかった。
例示的な実施形態
以下の例は、特定の技術の実施形態に関するものであり、そのような実施形態を達成するために使用または他の方法で組み合わせることができる特定の特徴、要素、またはステップに関するものである。
