Abstract: The present invention provides a method for treating a disease in a human subject in need thereof, wherein the disease is selected from the group consisting of inflammation, bronchiolitis and cystic fibrosis, and wherein the method comprises repeatedly administering to the human subject a gas mixture comprising nitric oxide at a concentration from about 144 to about 176 ppm for a first period of time, followed by a gas mixture containing no nitric oxide for a second period of time, wherein the administration is repeated for a time sufficient to: a) reduce the level of at least one inflammatory biomarker in the human subject when compared to the level of the inflammatory biomarker prior to the administration; b) reduce the microbial density by 1 to 2 log units as measured by colony forming units in the human subject when compared to the microbial density prior to the administration; or c) a combination thereof.

Abstract: The present invention relates to a method of treating a human subject suffering from a disease or disorder that is manifested in the respiratory tract or a disease or disorder that can be treated via the respiratory tract, the disease or disorder being associated with a nosocomial infection, the method including subjecting the subject to intermittent inhalation of gNO at a concentration of at least 160 ppm, thereby treating the disease or disorder.

Abstract: A system for inhalation, comprising gas supply apparatus configured to separately supply at least NO, and a carrier gas mixture which contains O2; a mixer apparatus configured for receiving gases from the supply apparatus and mixing the NO with the carrier gas mixture to provide a therapeutic mixture; an inhaler device configured for receiving the therapeutic mixture and releasing the therapeutic mixture in an enclosed space of the inhaler device; a chemical sensing assembly configured for providing data pertaining to a concentration of at least NO2 in the inhaler device; and a controller configured for controlling flow of the therapeutic mixture responsively to the data.

Abstract: A method of treating a human subject which is effected by intermittent inhalation of gaseous nitric oxide at a concentration of at least 160 ppm is disclosed. The method can be utilized for treating a human subject suffering from, or prone to suffer from, a disease or disorder that is manifested in the respiratory tract, or from a disease or disorder that can be treated via the respiratory tract. The disclosed method can be effected while monitoring one or more of on-site and off-site parameters such as vital signs, methemoglobin levels, pulmonary function parameters, blood chemistry and hematological parameters, blood coagulation parameters, inflammatory marker levels, liver and kidney function parameters and vascular endothelial activation parameters, such that no substantial deviation from a baseline in seen in one or more of the monitored parameters.
