The present invention generally relates to the improvement of tissue health by increasing local blood flow. In some aspects of the invention, increased local blood flow is effected by the transdermal delivery of the nitric oxide precursor L-arginine and/or its derivatives alone, or optionally in conjunction with an adjunct such as theophylline. The transdermal delivery is effected, in certain embodiments through the means of a hostile biophysical environment, such as that created by a high ionic strength environment. Various pathological states caused by, or occurring in conjunction with, insufficient blood flow, can be treated using the systems and methods of the invention as described herein. In other embodiments, increased blood flow using the systems and methods of the invention may result in enhanced healing, for example, through greater availability of the constituents of the blood. Examples of conditions which may benefit from increased blood flow include, but are not limited to, erectile dysfunction, hair loss, female sexual dissatisfaction, sagging facial or other body tissue, peripheral vascular disease including claudication, neuropathy, skin ulcers, bone healing, wound healing, viral and bacterial infection, and skin grafting.

The present invention refers to the use of phthalimide and/or sulphonamide derivatives with nitric oxide donor properties, which have important activities in increasing the gamma-globin gene expression and anti-inflammatory and analgesic activities, effective in the treatment of hematologic diseases which require reducing the TNF-α levels and an exogenous source of nitric oxide. More particularly, the present invention describes the use of such phthalimide and/or sulphonamide derivatives for the treatment of sickle-cell disease. The invention also has as a novel characteristic the disclosure of new functionalized phthalimide derivatives designed from the prototypes thalidomide and hydroxyurea, and designed rationally through the strategy of molecular hybridization for the treatment of said diseases. The invention still discloses a new method for obtaining a specific sulphonamide derivative which can be used in the preparation of a drug for the treatment of diseases which require reducing the levels of the TNF-α factor and an exogenous source of nitric oxide.

The invention relates to a nitric acid-free pickling method for hot-rolled 201 austenitic stainless steel. The nitric acid-free pickling method for the hot-rolled 201 austenitic stainless steel comprises the step that pre-pickling, first-stage nitric acid-free pickling and second-stage nitric acid-free pickling are conducted on strip steel in sequence, wherein a (H2SO4+Fe<3+>+Fe<2+>+H2SiF6+H2O2) mixed pickling solution is adopted in the two stages of nitric acid-free pickling. According to the nitric acid-free pickling method for the hot-rolled 201 austenitic stainless steel, the mixed pickling solution prepared from concentrated sulfuric acid, hydrogen peroxide and fluorosilicic acid is adopted so that the pickling requirement of the hot-rolled 201 austenitic stainless strip steel can be met, nitric acid-free pickling of the strip steel is achieved, the situation that high-pollution nitric oxides and nitrogen-containing wastewater are generated when nitric acid-containing mixed acid is used for pickling is avoided, and thus environment pollution is reduced.

The present invention relates to a method for generating nitric oxide, which comprises the steps of: providing a precursor solution comprising a nitric oxide precursor in a first reservoir (12), guiding the precursor solution through a reaction chamber (16), thereby subjecting the precursor solution to radiation to generate nitric oxide, guiding the generated nitric oxide out of the reaction chamber (16) by a stream of carrier gas, and guiding the reacted solution into a second reservoir (14). The method according to the invention provides a method of generating nitric oxide, or a flow of nitric oxide comprising gas, in which the concentration of the nitric oxide may be kept especially constant. Also claimed is an apparatus for generating nitric oxide comprising reservoirs for the precursor solution and the reacted solution and a reaction chamber.

The invention relates to a catalyst for removing nitric oxide, the catalyst is mainly used for solving the problems that in the prior art, the activity of the catalyst is low or the selectivity is poor under a high-temperature condition, and the nitrogen oxide cannot be effectively removed. A SOL-GEL method is adopted, a certain amount of silica SOL is mixed with an aqueous solution or alcohol solution containing a soluble aluminum salt to obtain a mixture, the mixture is dropwise added into an inorganic silver salt aqueous solution, after aging, drying, roasting and the like, a silver catalyst loaded with silicon oxide and aluminum oxide is prepared, metal oxides of IVB and VB are adopted for modification, and the problems are well solved. The catalyst is used in the reaction for removingnitrogen oxide waste gas, can be used to reduce nitrogen oxides effectively, has high catalytic activity and long service life, is simple and convenient to prepare and relatively low in price, and issuitable for industrial application.
