A simple, biocompatible system and procedure for generating nitric oxide (NO) is described. A mixture of powdered sodium nitrite, ascorbic acid, and maleic acid (or another organic acid of adequate strength) immediately generates nitric oxide (NO) on treatment with water. To slow down the NO generation, one may prepare an ointment from a nonaqueous medium (petrolatum, Vaseline™) and the three powdered ingredients, which on being applied topically on the skin will release NO as water permeates through this medium; alternatively, one may convert the aqueous sodium nitrite solution into a gel with hydroxyethylcellulose (or other gel-forming compound) and combine this gel with another gel obtained from aqueous ascorbic and maleic acids with hydroxyethylcellulose for topical application (on intact skin, burns intra-cavity, burns, intra-cavity, etc.). The two gels may be admixed immediately before use (possibly from a single container with separate chambers and dual nozzle, via pushing or squeezing the two gels through the nozzle), or may be applied in sandwich-like fashion (possibly as a transdermal patch) for further slowing down the delivery of NO.

Transcutaneous immunization can deliver antigen to the immune system through the stratum corneum without physical or chemical penetration to the dermis layer of the skin. This delivery system induces an antigen-specific immune response without the use of a heterologous adjuvant. Although perforation of intact skin is not required, superficial penetration or micropenetration of the skin can act as an enhancer; similarly, hydration may enhance the immune response. This system can induce antigen-specific immune effectors after epicutaneous application of a formulation containing one or more antigens. The formulation may initiate processes such as antigen uptake, processing, and presentation; Langerhans cell activation, migration from the skin to other immune organs, and differentiation to mature dendritic cells; contacting antigen with lymphocytes bearing cognate antigen receptors on the cell surface and their stimulation; and combinations thereof. Systemic and/or regional immunity may be induced. Immune responses that provide prophylactic and/or therapeutic treatments are preferred. Antigenic activities in the formulation may be found in the same molecule, two or more different molecules dissociated from each other, or multiple molecules in a complex formed by covalent or non-covalent bonds. For antigens which are proteinaceous, they may be provided in the formulation as a polynucleotide for transcutaneous genetic immunization. Besides simple application of a dry or liquid formulation to the skin, patches and other medical devices may be used to deliver antigen for immunization.

A transcutaneous immunization system delivers antigen to immune cells without perforation of the skin, and induces an immune response in an animal or human. The system uses an adjuvant, preferably an ADP-ribosylating exotoxin, to induce an antigen-specific immune response (e.g., humoral and/or cellular effectors) after transcutaneous application of a formulation containing antigen and adjuvant to intact skin of the animal or human. The efficiency of immunization may be enhanced by adding hydrating agents (e.g., liposomes), penetration enhancers, or occlusive dressings to the transcutaneous delivery system. This system may allow activation of Langerhans cells in the skin, migration of the Langerhans cells to lymph nodes, and antigen presentation.

The present invention includes a topical anesthetic composition having one or more local anesthetic agents, a penetration enhancer, and an anhydrous, volatile solvent combined to provide a liquid homogenous solution. The present invention may also include water in the topical anesthetic composition as concentration levels low enough to avoid precipitation of the local anesthetic agent and penetration enhancer from solution and undesired enhanced delivery of the local anesthetic agent through the skin or mucosa to the systemic circulation. The topical anesthetic composition can be conveniently sprayed onto intact skin and can be absorbed percutaneously with greater efficacy in order to shorten the time needed for the anesthesia to take effect.

Transcutaneous immunization can deliver antigen to the immune system through the stratum corneum without physical or chemical penetration to the dermis layer of the skin. This delivery system induces an antigen-specific immune response. Use of skin-active adjuvants is preferred. Although perforation of intact skin is not required, superficial penetration or micropenetration of the skin can act as an enhancer; similarly, hydration may enhance the immune response. This system can induce antigen-specific immune effectors after epicutaneous application of a formulation containing one or more antigen and adjuvant.

The invention discloses a skin exchanging method and apparatus for application software display interface. The method comprises steps of acquiring a to-be-updated skin resource package set during start and operation of application software, loading the skin resource package set and refreshing application interface. The skin resource package set is achieved when all skin resources of the application interface of the application software are sorted. By the use of the skin exchanging method, a problem that the whole software interface in relative technology usually has only one skin package file and therefore a user has to re-download the resource during skin update can be solved, so resource utilization rate can be reduced and a technical problem of bandwidth resource can be solved.

The invention relates to a method and composition for synergistic topical therapy of the symptoms of neuromuscular pains. In this method, for intact skin or open skin, there is used a suitable topical pharmaceutical formulation, which is loaded in a suitable dose relationship with a sodium channel blocker from the class of local anesthetics of the ester or amide type and a substance from the class of non-steroidal anti-inflammatory drugs, and which releases these substances selectively onto or under the skin region. By the simultaneous inhibition of the initial inflammatory pain factors at the cellular level and also of the transmission of neuronal pain impulses in reaction thereto, this therapy achieves pharmacologically more effective alleviation of neuromuscular pain.

The skin serves as a barrier that protects the body from the external environment and prevents water loss. This barrier function also prevents most hydrophilic or hydrophobic and large molecular weight ingredients (>500 kDa) from penetrating intact skin. Until recently, methods to increase stratum corneum permeability were generally not effective enough to make the stratum corneum so permeable that the barrier posed by the viable epidermis mattered. However, that has now changed with the development of the present embodiment's physical methods and highly optimized chemical formulations, such that we revisited the permeability of the full epidermis with the example embodiment's constructs and not focus only on the stratum corneum. This example embodiment therefore tests the hypothesis that the viable epidermis offers a significant permeability barrier to both small molecules and macromolecules that becomes the rate limiting step.
